如图所示,平行四边形ABCD各角的平分线相交于EFGH

∵∠CAB+∠ABD=180°

∴∠FAB+∠FBA=90°

在三角形AFB中,∠AFB=90°

∵∠EFG与∠AFB是对顶角

∴∠EFG=90°

同理可证 ∠FEH=90° ∠EHG=90° ∠HGF=90°

∴四边形EFGH为矩形。

请教众位大哥关于CBA 和CBQ的问题

其实并不冲突的;只有当CBQ为HIGH,CBA为NO的组合时才由C1、C2、PT、CRO、CRH、TO等参数来决定,也就是说,参数CBQCBA的设定优先级别比C1C2等参数的级别高;当CBQ为HIGH,CBA为YES的组合时,小区只允许切入,不允许选择和重选,这样的情况对高话务时,可减少信令负荷量;而剩下两个组合时,可以选择话务量相对较低的小区驻留。

广联达的3个软件GGJ GCL CBQ 之间需要怎么连贯起来 是不是先画好GGJ 然后导入GCL

GGJ主要算的就是钢筋,算钢筋需要把工程的主体结构全画出来,导入GCL中,这时候还有一些内外墙装饰,地面、天棚、屋面等部分没画,需要把这部分也画上,然后汇总计算得出工程量。至于是不是要GCL导入GBQ,我的做法是不导入,因为你要导入GBQ就得在GCL中把项目特征什么的编辑完成,这样还不如直接在GBQ中直接弄了,只要GGJ和GCL出个量就行了。

交换机的队列调度算法的改进方法有哪些

1. 基于权重的调度算法:在传统的FIFO(先进先出)队列调度算法的基础上,为不同的流设置不同的权重值,根据权重值来进行队列的调度。这种算法可以根据流的重要程度来保证重要流的传输性能。2. 公平队列调度算法(Fair Queuing):公平队列调度算法是一种多类别队列调度算法,它通过将输入数据分配到不同的虚拟队列中,根据每个队列的比重来分配资源。在这个算法中,每个流都会被分配同等的带宽。3. 最短剩余处理时间优先算法(Shortest Remaining Processing Time First):这种算法基于任务处理时间来对队列中的数据进行调度。任务处理时间较短的流会比处理时间较长的流先进行调度。4. 队列退让机制(Queue Management):当队列过载时,队列退让机制可以降低非重要数据的优先级,从而确保重要数据的带宽满足率。常见的队列退让机制有RED(随机早期检测)、WRED(加权随机早期检测)和CBWFQ(基于类别的加权公平队列)等。5. 带宽保障算法(Bandwidth Guarantee):通过为每个类别或流分配一定的带宽,来保证它们的传输性能。这种算法可以通过调整带宽分配来实现对重要流的优先级控制。6. 基于流量分类的调度算法(Class-based scheduling):将数据流划分为不同的类别,并按照预设的优先级和权重进行调度。这种算法能够进行精细的流量控制,提高网络的可维护性和易管理性。

阐述手机入网的基本过程

[转帖]手机入网过程一、手机的入网过程手机开机后根据设定,以手动或自动方式选择网络。手机寻找选定网络中的合适小区,并调谐到该小区的控制频点。如果需要,手机还将进行位置更新(LOCATION UPDATING)或国际移动用户识别码(IMSI) 附着(ATTACH)。选择小区后,手机通过测量如发现更好的小区,则进行小区重选。当手机从网络覆盖的盲区回到覆盖区,手机将重新选网。1.网络选择手机按照以下优先规则选择网络:a.归属网(HPLMN)b.SIM卡中设定的网络优先顺序c.信号强度大于-85dBm的网络按随机顺序d.其它网络按信号强度的强弱顺序如果登记成功,手机显示该网络,否则,手机显示NO SERVICE或进入受限服务状态。2.小区选择选择网络后,手机寻找所选网络的合适小区,其规则如下:a.小区属于所选网络b.小区未被禁入c.小区LA不在禁止漫游LA表之列d.手机和基站间的传输损耗低于网络规定的阈值通过小区参数CBQ可以设置在空闲模式下小区选择的优先级。CBQ=1,则小区优先级为低(LOW);CBQ=0,则小区优先级为常态(NORMAL)。小区选择方式有以下两种:a.正常小区选择这种情况下,手机不知道频段内的哪些频点是BCCH载波,手机首先搜索一定数目(900M 30个、1800M 40个)的最强信号频点,按强弱顺序,手机通过识别频率校正信道(FCH)判断是否是BCCH频点。手机将选择满足小区选择准则并且优先级是常态的第一个BCCH。如果所有小区的优先级均为低(LOW即CBQ=1〕,则手机选取它们中信号最强的小区〔即读取过程中第一个满足小区选择准则的小区)。由于CBQ是GSM规范PHASE 2的功能,因此对PHASE 1的手机不起作用。b.预存频点表小区选择手机关机时,存储了登记网络的相邻小区频点表。在该网络覆盖的区域开机后,手机首先据此搜寻小区,如果手机虽然解出某频点的广播信息,但是未能选择该小区,手机将检查其相邻小区频点表并搜寻SIM卡中所没有存储的频点。该方式下小区优先级准则仍然适用。二、网络与小区选择的信令内容在入网过程中,手机搜寻频段内的BCCH频点并测量其信号强度,然后按照信号的强弱顺序,分别读取相应小区的同步信道(SCH)和广播控制信道(BCCH)中的系统信息。使用TEMS测试手机可以监测手机入网的部分操作流程。手机在入网过程中读取以下无线接口的第三层消息,其消息所包含的参数如下:同步信道信息(SYNCH CHANNEL INFORMATION):BSIC系统信息类型3 (SYSTEM INFORMATION TYPE 3):MCC、MNC、LAC、CBQ以及随机接入控制、BCCH控制信道、小区选择与小区重选等参数系统信息类型4 (SYSTEM INFORMATION TYPE 4〕:MCC、MNC、LAC、CBQ以及随机接入控制、信道描述、小区选择与小区重选等参数系统信息类型2 (SYSTEM INFORMATION TYPE 2〕:邻区BCCH表、NCC等参数手机开机时的位置更新过程:(1)手机向系统请求分配信令信道(SDCCH)。(2)MSC收到手机发来的IMSI可及消息。(3)MSC将IMSI可及信息再发送给VLR,VLR将IMSI不可及标记更新为IMSI可及。(4)VLR反馈MSC可及信息信号。(5)MSC再将反馈信号发给手机。手机周期性位置更新的过程:(1)含有周期性登记的系统信息;(2)激活手机及MSC中的相关计时器;(3)手机计时器到时后激活周期性登记步骤;(4)系统确认,计时器清零。

DCS1800的空闲状态(IdleMode)的参数选择

小区选择参数是指手机开机后选择最佳小区进行登记的参数。根据GSM规范,小区选择采用C1准则,C1计算公式:C1=(RxLev-RxLev_Access_Min)-MAX(ms_txpwr_max_cch-P,0)其中,RxLev:手机平均接收电平;RxLev_Access_Min:小区参数,小区最小接入电平;ms_txpwr_max_cch:小区参数,手机允许最大发射功率;P:手机实际最大发射功率。手机开机后逐一扫描GSM频点,据此得到一组根据场强高低顺序排列的BCCH频点,且C1大于零,若C1小于零,则手机不能接入该小区。对于Phase1手机,手机会选择C1最大的小区作为其服务小区。 采用小区级别参数(CBQ)来定义小区的级别,用于网络控制手机对于小区的选择。该参数包含于“小区选择参数”信息中在每个小区BCCH广播的系统信息中周期性向手机发送。CBQ=0代表正常级别小区(Normalprioritycell);CBQ=1代表低级别小区(Lowprioritycell)。Phase1手机不受控于CBQ参数,手机直接登记在C1最大的小区,而且一般采用C1算法进行小区重选。Phase2手机受控于CBQ参数,,手机先选择高级别(CBQ=0)中C1最大的小区,当发现不了级别高的小区时,才在级别低的小区中选择C1最大的小区登记。对于Phase2的GSM900手机,每次小区选择,在没有得到高优先级的小区存在的消息前,必须扫描所有的信道进行判断,并且在小区重选过程中,通过其他方法来控制手机在空闲状态下的小区选择。目前,各大城市的DCS1800网络已经发展得较为成熟,DCS1800与GSM900可根据密度,具体信道配置及相应话务负荷设置小区的级别参数,调整双频网话务的分布,减少不必要的拥塞和提高通话质量。从实际网络安装情况看,DCS1800与GSM900共站址情况较多,但是DCS1800安装的载频数要少于GSM900。我们既要让DCS1800吸收一定的话务量,又不能降低通话质量和产生拥塞,因此建议按如下设置然后再进行调整和优化:RxLev_Access_Min(900M)=12,RxLev_Access_Min(1800M)=18,CBQ(900)=1(低级别),CBQ(1800)=0(正常级别),即GSM900的小区级别(CBQ)设为低级别,双频手机入网时,只要有接收电平大于入网电平(RxLev_Access_Min)的DCS1800小区存在,手机将选择GSM1800小区登记入网。对于Phase2的单频GSM900手机,在900M小区中选择C1最大的小区登记入网。 对于Phase2手机,小区重选需根据C2和C1参数来判断。空闲模式时,系统信息2包含了切换邻区表信息,系统信息2、2bis和2ter则通过BCCH广播,参数CRO、temporary_offset和penalty_time在每个小区广播的系统信息中发送。C2=C1+CRO-TO*H其中CRO:cell_reselect_offset,小区重选调整值;TO:temporary_offset,小区重选临时调整值,小区重选参数之一;H:H=0,penalty_time–T<0;H=1,penalty_time–T>0;T:最强邻区所维持的时间,penalty_time:惩罚时间,取值31时,C2=C1-CRO。当最强邻区所能维持的时间长于人工设定的惩罚时间(penalty_time)时,手机较容易重新选定该小区为服务小区。CRO的设定,对于DCS1800,CRO=3-5左右;于penalty_time(惩罚时间),DCS1800,penalty_time=1-2(为40-60秒);对于覆盖较小的GSM900小区,可以设为penalty_time=1(为40秒)。

如图,P是等边三角形ABC内的一点,连接PA,PB,PC,以BP为边做∠PBQ=60°,且BQ=BP。连接CQ。求证AP=CQ

由于三角形ABC是等边三角形。所以角ABC是60度。由于角PBQ也是60度,因此角ABP=角CBQ。又因为边AB=边CB,边BP=边BQ,因此三角形ABP和三角形CBQ是全等三角形。根据全等三角形的定理,推得AP=CQ

P,Q分别是圆内接四边形ABCD的对角线AC,BD的中点,若角BPA=角DPA,证明:角AQB=角CQB

延长BP、DP分别与圆相交与B"和D",因为P是AC中点,且∠BPA=∠DPA ,根据圆的对称性可知,DB"与BD"均平行于AC。于是,∠APD=∠BCD。加上∠PAD=∠CBD,就有ΔAPD∽ΔBCD于是,AD/AP=BD/BC。因为P、Q分别是AC、BD的中点,所以就有AD/AC=BQ/BC加上,∠CAD=∠CBQ,就有ΔCAD∽ΔCBQ于是就有,∠ADC=∠BQC,从而∠CQD=∠CBA同理,∠AQD=∠ABC于是:∠AQB=∠CQB,命题得证。

心灵鸡汤英语小故事阅读

  自改革开放以来,我国对外交流逐渐密切,因此社会各界对于英语的重视程度也与日俱增,在大学阶段的英语教学过程中对于基础知识和语法使用的内容比例大范围下降,而增加了 实用英语 的内容。下面是我带来的心灵鸡汤英语小 故事 阅读,欢迎阅读!  心灵鸡汤英语小故事阅读篇一   Flotsam, Jetsam, and Liberty   By James Carey   Perhaps more than anything else in the world, I believe in liberty: liberty for myself, liberty for my fellow men. I cannot forget the legend engraved on the base of the Statue of Liberty on Bedlows Island in New York Harbor: Give me your tired, your poor, your huddled masses yearning to breathe free, the wretched refuse of your teeming shore. Send these, the homeless tempest tossed to me. I lift my lamp beside the golden door. That is the voice of America.   As one small part of it, one tiny decibel in its sound, I, as a free individual of America, believe in it. It makes no boast of noble ancestry. On the contrary, it admits honestly that each of us in this country, with a possible and qualified exception of our native Indians, is a displaced person. In a particular kind of way, the Indian was our first displaced person. If you and I did not come from abroad ourselves, our forefathers did. The scores that drove them was economic, political, or religious oppression.   Oppression has always strewn the shores of life with wretched human refuse. We who today are the proud people of a proud country are what might be called the reclaimed refuse of other lands. The fact that the flotsam and the jetsam, the persecuted and the pursued of all these other lands, the fact that they came here and, for the most part, successfully started life anew, this renews my faith in the resilience of a human individual and the dignity of man.   There are those who say we should be content with the material benefits we have accrued among ourselves. I cannot accept that for myself. A laboring man needs bread and butter, and cash to pay the rent. But he would be a poor individual, indeed, if he were not able to furnish the vestibule of his mind and his soul with spiritual embellishments beyond the price of a union contract.   I mean by this that I believe it is important for a man to discover, whether he is an electrical worker or an executive, that he is an individual with his own resources and a sense of the dignity of his own person and that of other men. We are separate. We are collective. Man can be strong alone but not indomitable, in isolation. He has to belong to something, to realize he is not created separately or apart from the rest of mankind, whether he is an American or a Mohammedan.   I am stirred by the abundance of the fields, the forest, the streams, and the natural resources they hold. But do these things make me important? Have we wrought the miracle of America because of these riches we hold? I say, no. Our strength—and I can say my strength, too, because I am a part of this whole—lies in a fundamental belief in the validity of human rights. And I believe that a man who holds these rights in proper esteem is greater, whether he is recognized or not.   As an individual, I must face the future with honesty and faith, in the goods things that have made us mighty. I must have confidence in myself, in others, and all men of goodwill everywhere, for freedom is the child of truth and confidence.   心灵鸡汤英语小故事阅读篇二   Dreams Are the Stuff Life Is Made Of   By Carroll Carroll   I believe I am a very lucky man.   My entire life has been lived in the healthy area between too little and too much. Iu2019ve never experienced financial or emotional insecurity, but everything I have, Iu2019ve attained by my own work, not through indulgence, inheritance, or privilege.   Never having lived by the abuses of any extreme, Iu2019ve always felt that a workman is worthy of his hire, a merchant entitled to his profit, an artist to his reward.   As a result of all this, my bargaining bump may be a little underdeveloped, so Iu2019ve never tried to oversell myself. And though I may work for less than I know I can get, I find that because of this, Iu2019m never so afraid of losing a job that Iu2019m forced to compromise with my principles.   Naturally in a life as mentally, physically, emotionally, and financially fortunate as mine has been, a great many people have helped me. A few meant to, most did so by accident. I still feel I must reciprocate. This doesnu2019t mean that Iu2019ve dedicated my life to my fellow man. Iu2019m not the type. But I do feel I should help those Iu2019m qualified to help, just as Iu2019ve been helped by others.   What Iu2019m saying now is, I feel, part of that pattern. I think everyone should, for his own sake, try to reduce to six hundred words the beliefs by which he lives—itu2019s not easy—and then compare those beliefs with what he enjoys—not in real estate and money and goods, but in love, health, happiness, and laughter.   I donu2019t believe we live our lives and then receive our reward or punishment in some afterlife. The life and the rewardu2026the life and the punishment—these to me are one. This is my religion, coupled with a firm belief that there is a Supreme Being who planned this world and runs it so that “no man is an island, entire of himselfu2026” The dishonesty of any one man subverts all honesty. The lack of ethics anywhere adulterates the whole worldu2019s ethical content. In these—honesty and ethics—are, I think, the true spiritual values.   I believe the hope for a thoroughly honest and ethical society should never be laughed at. The most idealistic dreams have repeatedly forecast the future. Most of the things we think of today as hard, practical, and even indispensable were once merely dreams.   So I like to hope that the world need not be a dog-eat-dog jungle. I donu2019t think Iu2019m my brotheru2019s keeper. But I do think Iu2019m obligated to be his helper. And that he has the same obligation to me.   In the last analysis, the entire pattern of my life and belief can be found in the words “do NOT do unto others that which you would NOT have others do unto you.” To say “Do unto others as you would have others DO unto you” somehow implies bargaining, an offer of favor for favor. But to restrain from acts which you, yourself, would abhor is an exercise in will power that must raise the level of human relationship.   “What is unpleasant to thyself,” says Hillel, “THAT do NOT unto thy neighbor. This is the whole law,” and he concluded, “All else is exposition.”   心灵鸡汤英语小故事阅读篇三   A Ball to Roll Around   By Robert Allman   I lost my sight when I was 4 years old by falling off a boxcar in a freight yard in Atlantic City, New Jersey, and landing on my head. Now, I am 32. I can vaguely remember the brightness of sunshine and what color red is. It would be wonderful to see again. But a calamity can do strange things to people.   It occurred to me the other day that I might not have come to love life so, as I do, if I hadnu2019t been blind. I believe in life now. I am not so sure that I would have believed in it so deeply, otherwise. I donu2019t mean that I would prefer to go without my eyes. I simply mean that the loss of them made me more appreciate what I had left.   Life, I believe, asks a continuous series of adjustments to reality. The more readily a person is able to make these adjustments, the more meaningful his own private world becomes. The adjustment is never easy. I was bewildered and afraid, but I was lucky. My parents and my teachers saw something in me—oh, a potential to live you might call it—which I didnu2019t see. And they made me want to fight it out with blindness.   The hardest lesson I had to learn was to believe in myself. That was basic. If I hadnu2019t been able to do that, I would have collapsed and become a chair rocker on the front porch for the rest of my life. When I say believe in myself, I am not talking about simply the kind of self-confidence that helps me down an unfamiliar staircase alone. That is part of it, but I mean something bigger than that: an assurance that I am, despite imperfections, a real, positive person; that somewhere in the sweeping, intricate, pattern of people, there is a special place where I can make myself fit. It took me years to discover and strengthen this assurance. It had to start with the most elementary things.   When I was a youngster, once a man gave me an indoor baseball. I thought he was mocking me, and I was hurt.   “I canu2019t use this,” I said.   “Take it with you, “ he urged me, “and roll it around.”   The words stuck in my head: “Roll it around, roll it around.” By rolling the ball, I could listen where it went. This gave me an idea—how to achieve a goal I had thought impossible: playing baseball. At Philadelphiau2019s Overbrook School for the Blind, I invented a successful variation of baseball. We called it groundball.   All my life, I have set ahead of me a series of goals, and then tried to reach them one at a time. I had to learn my limitations. It was no good to try for something I knew at the start was wildly out of reach, because that only invited the bitterness of failure. I would fail sometimes anyway, but on the average, I made progress.   I believe I made progress more readily because of a pattern of life shaped by certain values. I find it easier to live with myself if I try to be honest. I find strength in the friendship and interdependence of people. I would be blind, indeed, without my sighted friends. And very humbly, I say that I have found purpose and comfort in a mortalu2019s ambition toward godliness.   Perhaps a man without sight is blinded less by the importance of material things than other men are. All I know is that a belief in the higher existence of a nobility for men to strive for has been an inspiration that has helped me more than anything else to hold my life together.

阿波罗创始人是谁

阿波罗的创始人是罗兰冈佩特(Roland Gumpert),他从最早开始就在奥迪工作。购买这款阿波罗车的车主,一定要注意车子的性能。该车最高时速可达360km/h,百公里加速时间仅需三秒。动力方面,该车搭载奥迪8缸发动机,采用输出功率100kw,最大马力650匹的电动机。阿波罗的外形很吸引人。夸张的欧翼门虽然缺乏安全系数,但却能吸引大家的眼球。车尾采用大面积扩散器,车尾造型非常独特。阿波罗的车标以红色盾牌为基础,上面有一只白色的飞行兽。从现代人的审美角度来看,这款车的造型与其他车格格不入,让车尽最大努力减轻重量。车是碳纤维装饰,连大灯基本都是碳纤维装饰。阿波罗车在国内车市还是比较少见的。由于过度的小众品牌和另类夸张的造型,这个汽车品牌失去了大量的买家,加上高昂的车价,汽车销量一直处于低迷状态。那么,看了边肖的介绍,你对阿波罗的创始人是谁有更深的了解了吗?希望今天边肖的介绍能帮助到大家。如果觉得有帮助,请推荐给更多的人。

关于仰望明月的诗句

1. 关于仰望诗句 关于仰望诗句 1. 关于仰望的句子 有人说,仰望天空是在仰望幸福。 有人说,45°角仰望天空,其实是不让眼泪掉下来,不让别人看见自己的忧伤。 其实,仰望幸福的人有时也被别人仰望着…… 有本书叫仰望幸福的角度 【转】 我常听人说,人能仰望便是幸福。也许是在仰望的过程中能感受到那种满足吧,但也只是一刹那的瞬间。我从不仰望什么,因为我不懂仰望的含义;也许在我的理解范围内,这个词,也就是那么回事而已。。并不占有重要的地位。 想想,我仰望过的只有天空,和不认识的陌生人。那种仰望只是把脸抬高,用自己微弱的目光接对上一双不认识的眼睛或者一片蔚蓝。很简单,在抬头时没有半点犹豫和期待,只是重复着机械枯燥的动作,仰望即是自然的。 而我也从未把它与幸福连接起来。 剖析幸福一词,解释有很多种,可以灵活的运用在不同的语句中,不同的理解上,不同的心情里。幸福亦是简单的也充满复杂。 仰望幸福的角度,那对我来说是一个陌生的句子,我从未仰望过幸福,我总是沉浸在一片迷茫中。它嘈杂的声音淹没了我唯一的声路,深灰色覆盖了最后一束光。。.我的世界从此荒芜,像一个漩涡,致命的吸引着我向前走,却从来不告诉我再往前挪动一点就是深渊。我的世界不再有幸福可言。它随着水分蒸发了。而这也注定了我未来的所有,那都将是悲哀的。 这到什么时候呢。。.我开始试着抬头看,希望在模糊中找到一丝光线;像一只被束缚的残蝶,拼命地想要逃脱黑暗得到重生。也就是那时,我学会了仰望。我的神经不再麻木,思绪逆流成河,渐渐有了挣脱的力量;我清楚我要什么,我要摆脱什么。时间和岁月也不是永恒的,他就代表着一个人的一生,也许在不经意间,你生活的秒针就可能被那些陈旧的杂绪牵制,从此定格在原地。幸福也是如此。 当再一次有人问我,幸福是什么?其实仰望便是。 谁都是幸福的。 听到有人抱怨:我从来没有幸福过。。.反问,那你想要的幸福是什么呢?就会听到一阵沉默。仰望幸福的角度,也谁都没有一个固定的答案,但是每个人都知道该怎样仰望自己的幸福;至少清楚那并不是一件多么悲哀的事情。何必整日把自己泡在烦恼忧愁之中?行尸走肉般的度过自我所谓悲哀的人生呢?改变也只是那么一瞬间的事啊。。.并不期待有惊喜,同时也放下了所有烦恼,只是这么平平淡淡的就能得到幸福。 我看不到幸福的角度,但是我还是非常幸福。因为仰望。因为仰望的那一刻我认识了真正的自己,看到了自己以前从未看过的幸福。那,即使这样我也满足了。 想幸福吗?很简单哦,请抬头,跟我一样深呼吸,睁眼。。.. 仰望幸福的角度。。。. 2. 仰望诗词的天空 我的苍穹,我的梦…… “北冥有鱼,其名为鲲,鲲之大不知其几千里也。化而为鸟,其名为鹏,鹏之背不知其几千里也,怒而飞,其翼若垂天之云。”千百年前的庄周就幻想化为鹏鸟去感受背负青天的惬意,去诠释苍穹的博大,“大鹏一日腾风起,扶摇直上九万里”,这份与苍穹的第一次亲密接触,承受着一种超脱世俗重负的闲然。 “读诗使人明智,读史使人知礼”,而读天你可以身临其境感受到“天人合一”的自然神韵。仰望苍穹,就像在一部巨大的放映机前,你可以窥视整个历史的画面…… 歌舞升平,觥筹交错皇宫门外,宁静安谧的浣溪边,范蠡凝视苍穹,仰天长啸。系着彻骨的阵痛在开往吴国的车队后面,一遍又一遍地呼唤着西施这个名字,凄厉的喊声洞穿时空,我们不会忘记英雄失去心爱人的刻骨铭心…… 浩浩荡荡的迎亲队伍在花轿上坐着一位大清的公主,从这一刻起,她便离开了这个美丽的国都,去一个遥远而野蛮的地方,是紧张是新奇复杂的心情萦绕在心头挥之不去,但当她迈出花轿,双目触及蓝得澄净而耀眼的天宇的一刹那,所有的焦虑、迷惑都像空气中的泡沫一样被蒸发的一干二净。 蓝齐儿读懂她已是葛尔丹的女人,不再是皇阿玛怀里挚爱的娇女,因为这片圣洁的天空,广袤的草原,净化着她的魂灵,此刻她明了应踏的旅途…… 败落的残瓣洒落地上,风起吹皱一池春水,也吹凉了一颗疲惫的心。“生当作人杰,死亦为鬼雄”的雄心壮志,此刻徒留下“云中谁寄锦书来?……花自飘零,水自流”的心灵感伤,苍穹见证这一刻——孤独有着比死亡更深刻的痛苦。 仰望苍穹,听到刘禹锡纵情高歌“晴空一鹤排云上,便引诗情到碧霄”;仰望苍穹,毛泽东感悟:“天若有情天亦老,人间正道是沧桑”;仰望苍穹,张海迪留下:“即使翅膀断了,心中也要飞翔”的誓言………… 3. 关于仰望星空的诗歌20行 The More Loving One W.H.Auden Looking up at the stars, I know quite well 仰望群星的时分,我一清二楚, That, for all they care, I can go to hell 尽管它们关怀备至,我亦有可能赴地府, But on earth indifference is the least 可是尘世间我们丝毫不必畏惧 We have to dread from man or beast 人类或禽兽的那份冷漠。 How should we like it were stars to burn 倘若群星燃烧着关怀我们的激情, With a passion for us we could not return 我们却无法回报,我们作何感想? If equal affection cannot be 倘若无法产生同样的感情, Let the more loving one be me 让我成为更有爱心的人。 Admirer as I think I am 尽管我自视为群星的崇拜者, Of stars that do not give a damn 它们满不在乎, I cannot, now I see them, say 现在我看群星,我却难以启齿, I missed one terribly all day 说我成天思念一颗星星。 Were all stars to disappear or die 倘若所有的星星消失或者消亡, I should learn to look at an empty sky 我应该学会仰望空荡的天空, And feel its total dark sublime 同时感受天空一片漆黑的崇高, Though this might take me a little time 虽然这样可能要花费一点时间。 我收藏的诗中有一首是有关仰望星空的。 不过没有二十行。 给你欣赏欣赏吧。 (*"▽"*)u266a 4. 关于“仰望唐诗”的作文怎么写 我喜欢冬天,尤其冬天的夜晚。 喜欢风雨故人踏雪寻梅而来,或者我踩着踉跄的醉态归去。倘若有月光,忧郁的美丽,我会对月吟歌,诗心常和月光融合在一起。 最是,夜凉如水,掬一杯香茗,任飘洒的音符浸润在缕缕幽香里,冬夜里书梦唐朝,诗歌与爱情的故乡,我枕着醉马倚斜桥,满楼红袖招的唐诗睡去。 幸有唐诗我未孤。 我来竞何事,高卧沙丘城,城边有古树,日夕连秋声。鲁酒不可醉,齐歌空复情,思君若汶水,浩荡寄南征。在冬天的夜晚,当我需要表达和诉说什么的时候,没有任何文字能比唐诗更适合我的需要了。 冬夜,仰望唐诗的星空,是因为某种程度上唐诗为我们的人生建立了一种贵重的格调,使后世如我们者的情感有所寄托并得到确立。比如爱情,唐诗体现的是一种庄重质朴的情怀,就像现在雪花飘洒的冬夜,当我想念你的时候,李白告诉我应该这样说:思君若汶水,浩荡寄南征。 倾听 总是乐于倾听一些优美的声音。 像鸟鸣,洗亮了乡下的早晨。 像蛙鸣,将田野之夜咏唱得恢弘悠远。 坐在小楼里,倾听一夜的雨声。雨声之下,飘落多少唐诗和花朵? 站在讲台上,书声像一只只展翅而翔的鸟,飞出校园,飞出大山…… 涛声是一种宁静。雪落荒原是一种境界。 那么,时光的脚步呢? 仰望 有些景物是必须仰望的。 比如鹰,比如天空,比如高山…… 有些人是必须仰望的。 像李白,像范仲淹,像辛弃疾…… 有时我们仰望他们的为人,有时我们仰望他们的作品。 就像我痴心写作,惟恐我的浅薄,亵渎了文字的冰清玉洁。对于文字,我只能一辈子去仰望。 仰望崇高,感受卑鄙;仰望伟大,感受渺小;仰望纯洁,感受丑陋…… 仰望使头颅变得有份量,仰望使眼睛长上翅膀。 我们在仰望中感受自己和世界。 5. 一位老者孤独仰望青天诗句 出自盛唐诗人李白的《把酒问月》 青天有月来几时?我今停杯一问之。 人攀明月不可得,月行却与人相随。 皎如飞镜临丹阙,绿烟灭尽清辉发。 但见宵从海上来,宁知晓向云间没。 白兔捣药秋复春,嫦娥孤栖与谁邻? 今人不见古时月,今月曾经照古人。 古人今人若流水,共看明月皆如此。 唯愿当歌对酒时,月光长照金樽里。 赏析 这是一首应友人之请而作的咏月抒怀。全诗十六句,每四句一换韵。悠悠万古,长存不变的明月,是永恒时空里的奇迹,常常引起人类的无限遐思。前两句以倒装句式统摄全篇,以疑问句表达了诗人的这种困惑,极有气势。诗人停杯沉思,颇有几分醉意,仰望苍冥发问道:这亘古如斯的明月,究竟是从何时就存在的呢?这一对宇宙本源的求索与困惑,实际上是对自身的生命价值的思索和探寻,“停杯”二字生动地表现出他的神往与迷惑糅杂的情态。三四句写出了人类与明月的微妙关系。 古往今来,有多少人想要飞升到月中以求长生不老,但皆是徒然,而明月却依然用万里清辉普照尘世,伴随着世世代代繁衍生息的人们。两句写出了明月既无情又有情、既亲切又神秘的人格化的特性,蕴含着诗人向往而又无奈的复杂心境。“皎如”两句极写月色之美。浓重的云雾渐渐消散,月亮皎洁得有若悬挂在天际的明镜,散射出清澄的光辉,照临着朱红色的宫门。诗人以“飞镜”为譬,以“丹阙”、“绿烟”为衬,将皎洁的月光写得妩媚动人,光彩夺目。“但见”二句,借明月的夜出晓没来慨叹时光流逝之速。明月在夜间从东海升起,拂晓隐没于西天云海,如此循环不已,尘世间便在其反复出没中推演至今。两句中既表达了对明月踪迹难测的惊异,也隐含着对人们不知珍惜美好时光的深沉叹惋。

高考励志英语美文摘抄

  励志教育对于每一个个体的成长成才具有重要作用,贯穿于个体发展的全过程。我精心收集了高考励志英语美文,供大家欣赏学习!   高考励志英语美文:Dreams Are the Stuff Life Is Made Of   By Carroll Carroll   I believe I am a very lucky man.   My entire life has been lived in the healthy area between too little and too much. I"ve never experienced financial or emotional insecurity, but everything I have, I"ve attained by my own work, not through indulgence, inheritance, or privilege.   Never having lived by the abuses of any extreme, I"ve always felt that a workman is worthy of his hire, a merchant entitled to his profit, an artist to his reward.   As a result of all this, my bargaining bump may be a little underdeveloped, so I"ve never tried to oversell myself. And though I may work for less than I know I can get, I find that because of this, I"m never so afraid of losing a job that I"m forced to promise with my principles.   Naturally in a life as mentally, physically, emotionally, and financially fortunate as mine has been, a great many people have helped me. A few meant to, most did so by accident. I still feel I must reciprocate. This doesn"t mean that I"ve dedicated my life to my fellow man. I"m not the type. But I do feel I should help those I"m qualified to help, just as I"ve been helped by others.   What I"m saying now is, I feel, part of that pattern. I think everyone should, for his own sake, try to reduce to six hundred words the beliefs by which he lives—it"s not easy—and then pare those beliefs with what he enjoys—not in real estate and money and goods, but in love, health, happiness, and laughter.   I don"t believe we live our lives and then receive our reward or punishment in some afterlife. The life and the reward…the life and the punishment—these to me are one. This is my religion, coupled with a firm belief that there is a Supreme Being who planned this world and runs it so that “no man is an island, entire of himself…” The dishonesty of any one man subverts all honesty. The lack of ethics anywhere *** erates the whole world"s ethical content. In these—honesty and ethics—are, I think, the true spiritual values.   I believe the hope for a thoroughly honest and ethical society should never be laughed at. The most idealistic dreams have repeatedly forecast the future. Most of the things we think of today as hard, practical, and even indispensable were once merely dreams.   So I like to hope that the world need not be a dog-eat-dog jungle. I don"t think I"m my brother"s keeper. But I do think I"m obligated to be his helper. And that he has the same obligation to me.   In the last *** ysis, the entire pattern of my life and belief can be found in the words “do NOT do unto others that which you would NOT have others do unto you.” To say “Do unto others as you would have others DO unto you” somehow implies bargaining, an offer of favor for favor. But to restrain from acts which you, yourself, would abhor is an exercise in will power that must raise the level of human relationship.   “What is unpleasant to thyself,” says Hillel, “THAT do NOT unto thy neighbor. This is the whole law,” and he concluded, “All else is exposition.”   高考励志英语美文:Keep the Innocent Eye   By Sir Hugh Casson   When I Accepted the invitation to join in "This I Believe," it was not-goodness knows-because I felt I had anything profound to contribute. I regarded it-selfishly, perhaps-as a chance to get my own ideas straight. I started, because it seemed simplest that way, with my own profession. The signposts I try to follow as an architect are these: to keep the innocent eye with which we are all born, and therefore always to be astonished; to respect the scholar but not the style snob; to like what I like without humbug, but also to train my eye and mind so that I can say why I like it; to use my head but not to be frightened to listen to my heart for there are some things which can be learned only through emotion; finally, to develop to the best of my ability the best that lies within me.   But what, you may say, about the really big problems of life- Religion? Politics? World Affairs? Well, to be honest, these great problems do not weigh heavily upon my mind. I have always cared more for the *** all simplicities of life-family affection, loyalty of friends, joy in creative work.   Religion? Well, when challenged I describe myself as "Church of England," and as a child I went regularly to church. But today, though I respect churchgoing as an act of piety and enjoy its sidelines, so to speak, the music and the architecture, it holds no significance for me. Perhaps, I don"t know, it is the atmosphere of death in which religion is so steeped that has discouraged me-the graveyards, the parsonical voice, the thin damp *** ell of stone. Even today a "holy" face conjures up not saintliness but moroseness. So, most of what I learned of Christian morality I think I really learned indirectly at home and from friends.   World Affairs? I wonder if some of you remember a famous prewar cartoon. It depicted a crocodile emerging from a peace conference and announcing to a huge flock of sheep labeled "People of the World", "I am so sorry we have failed. We have been unable to restrain your warlike ambitions." Frankly, I feel at home with those sheep-mild, benevolent, rather apprehensive creatures, acting together by instinct and of course very, very woolly. But I have learned too, I think, that there is still no force, not even Christianity, so strong as patrioti *** ; that the instinctive wisdom with which we all act in moments of crisis-that queer code of conduct which is understood by all but never formulated-is a better guide than any panel of professors; and finally that it is the inferiority plex, usually the result of an unhappy or unlucky home, which is at the bottom of nearly all our troubles. Is the solution, then, no more than to see that every child has a happy home? I"m not sure that it isn"t. Children are nearer truth than we are. They have the innocent eye.   If you think that such a philosophy of life is superficial or tiresomely homespun or irresponsible, I will remind you in reply that the title of this series is "This I Believe”-not "This I ought to believe," nor even "This I would like to believe”-but, "This I Believe."   高考励志英语美文:Flotsam, Jetsam, and Liberty   By James Carey   Perhaps more than anything else in the world, I believe in liberty: liberty for myself, liberty for my fellow men. I cannot forget the legend engraved on the base of the Statue of Liberty on Bedlows Island in New York Harbor: Give me your tired, your poor, your huddled masses yearning to breathe free, the wretched refuse of your teeming shore. Send these, the homeless tempest tossed to me. I lift my lamp beside the golden door. That is the voice of America.   As one *** all part of it, one tiny decibel in its sound, I, as a free individual of America, believe in it. It makes no boast of noble ancestry. On the contrary, it admits honestly that each of us in this country, with a possible and qualified exception of our native Indians, is a displaced person. In a particular kind of way, the Indian was our first displaced person. If you and I did not e from abroad ourselves, our forefathers did. The scores that drove them was economic, political, or religious oppression.   Oppression has always strewn the shores of life with wretched human refuse. We who today are the proud people of a proud country are what might be called the reclaimed refuse of other lands. The fact that the flotsam and the jetsam, the persecuted and the pursued of all these other lands, the fact that they came here and, for the most part, successfully started life anew, this renews my faith in the resilience of a human individual and the dignity of man.   There are those who say we should be content with the material benefits we have accrued among ourselves. I cannot accept that for myself. A laboring man needs bread and butter, and cash to pay the rent. But he would be a poor individual, indeed, if he were not able to furnish the vestibule of his mind and his soul with spiritual embellishments beyond the price of a union contract.   I mean by this that I believe it is important for a man to discover, whether he is an electrical worker or an executive, that he is an individual with his own resources and a sense of the dignity of his own person and that of other men. We are separate. We are collective. Man can be strong alone but not indomitable, in isolation. He has to belong to something, to realize he is not created separately or apart from the rest of mankind, whether he is an American or a Mohammedan.   I am stirred by the abundance of the fields, the forest, the streams, and the natural resources they hold. But do these things make me important? Have we wrought the miracle of America because of these riches we hold? I say, no. Our strength—and I can say my strength, too, because I am a part of this whole—lies in a fundamental belief in the validity of human rights. And I believe that a man who holds these rights in proper esteem is greater, whether he is recognized or not.   As an individual, I must face the future with honesty and faith, in the goods things that have made us mighty. I must have confidence in myself, in others, and all men of goodwill everywhere, for freedom is the child of truth and confidence.
