I can still remember when I met my best friend.She had just moved into the neighborhood and her grandmother brought her down to 1 me.I hid behind my motherland she hid behind her grandmother, 3 to look at each other.Soon we lost the 2 and started playing with each other.
In the 7th grade,I first lost touch with her.She was 4 family problems and I deserted her to be with the because they knew she had 5 people.None of my new friends liked her as much as I did because they knew she had 6.However,every summer we could always sit at each other’s house and watch soap operas,and talk about all the boys we liked.
It was last year when I noticed the problem.I guess I was too devoted in high school to 7 she needed someone there for her.Anyway,she made a new best friend and so did I.Then 1 didn’t know why,but she started cutting herself!
She then was diagnosed(诊断)with clinical depression.At first,1 was very 8 ,but we still stayed in 9 .I wanted to be there for her since her new best friend basically 10 her and people were calling her 11 .
Yesterday she came to me and said:“I never knew what a best friend was until you were the only person that would stop me cutting.I 12 you so much,and you didn’t even know you were 13 me.”
We both cried.And I guess a kind of 14 from my life so far is never to give up on your friends.Even if they aren’t as cool as others,or people think they are crazy,they need someone there.If you desert them,you will only be 15 yourself.

化学键与总能量的关系粤教版高一化学必修2第二章第一节
bonfanfan1年前1
liurantantian 共回答了13个问题 | 采纳率92.3%
答:化学键的键能越高,总能量就越大,化学键的键能越低,总能量就越小.化学键的键能决定于键的键长和成键原子的半径及所带的电荷数.化学键的断裂和形成是化学反应中能量变化的主要原因——化学键的断裂要吸收能量,化学键的形成要放出能量.知道一个化学反应是吸收能量还是放出能量,决定于反应物的总能量与生成物的总能量的相对高低.一般化学键的键能为一百到几百kJ/mol.氢键的键能约在40kJ/mol以下.化学键的形成把原子按一定方式牢固地结合成分子,所以它是使分子或晶体能稳定存在的根本原因.

全部走完需要6秒,先算6秒走的路程s=a*t^2=36*a,所以就是9节车厢!

If I were writing a history of my family, some of the darkest moments recorded would be those surrounding Christmas trees.One would certainly think otherwise; selecting and putting up our trees have always been filled with risk.For example, one afternoon dangerously close to Christmas Eve my mother bought what she thought to be a bargain, a glorious tree that was so full and tall that we could hardly get it onto the house.Once we did, my father immediately realized that we would have to hire a carpenter to build a stand for it.Another December, perhaps the very next one, we bought a tree earlier than we ever had before.We were happy with its shape and delighted that its size was manageable.We easily placed it in a stand, decorated(装饰)it from top to bottom, and then self-satisfiedly sat back by the fire in its soft light.Two or three days passed and the truth could not be hidden; we had bought a tree cut so long ago that its needles were coming off.There was nothing to do undecorated it, take it down, and begin treeshopping again.Our most recent Christmas tree offered still another difficult task.When we brought it home, once again it seemed larger than it had in the great outdoors.To complicate matters, we had bought a new stand, one whose nuts and bolts worked more mysteriously than those of our old stand.I persuaded two young neighbors to stop playing basketball and to help us get the tree into the house and set it correctly in the stand.Unfortunately, no one noticed the mud on our helpers’ shoes, so only after removing several reddish brown spots from the carpet were we able to discuss the question of where the lights and ornaments(装饰)were stored.Perhaps those who cut their own trees have tales more painful than these.I don’t care to hear them, as my family’s experiences are enough to cause me to make the following suggestion:“Let’s forget the tree next Christmas.Let’s simply hang some flowers on the front door and over the mirror in the hall.”
41.The darkest moments in the writer’s family were with the fact that________.
A.the family bought big Christmas trees

B.they had problems decorating their Christmas trees

C.they had problems picking suitable Christmas trees

D.they had problems finding carpenters for putting up Christmas trees.
42.We can learn from the passage that the writer would like to________.
A.forget about Christmas

B.get the neighbors to put up their trees

C.buy a better tree

D.make some other decorations to celebrate Christmas rather than the tree
43.When the writer said“mother bought what she thought to be a bargain”, he means________.
A.she bought the tree at a cheap price

B.she didn’t really want to buy it

C.she had to bargain hard with the salesman

D.she couldn’t afford a more expensive one
44.Which of the following can be the best for the passage?
A.How to Select a Christmas Tree B.No More Christmas Tree for US

C.Dark Moments of Life D.Christmas without Trees

你们是否还记得,有那样一片草地,承载着童年的奔跑和欢笑,你与伙伴们无忧地嬉戏打闹,累了便躺在草地上,将心灵栖息.
你们是否还记得,有那么一棵树,你曾经靠着它迷糊中睡着;在这棵树下,你的妈妈轻轻抚着你的手,说着温暖慈爱的话.
这是你们的童年,那草地,那树承载着你们美好的梦想与记忆.
可现如今,冰冷的斧头狠狠地劈下,那原本挺拔的树木凋零了生命,就像梦想失去了依托.城市上方,黑烟滚滚,入目的竟是灰色的空气,那些嫩绿的草已是不见了踪影.
于是我们悲伤地呼唤:将那绿色还给我们,把我们的童年和梦想还给我们!
那么诗人乔治?珀金斯?莫里斯于内心深处又发出了怎样的呐喊?他对那颗承载了他美好记忆的老橡树又是怎样深切的感情呢? 让我们走进诗人的内心世界一探究竟.

一:白炽灯的灯丝发生颤动.原因是灯丝中流的是交变电流,电流方向时刻在变化,灯丝处在磁场中,受力方向时刻在变化,所以产生颤动现象
二:不对.线圈平面转到中性面的瞬间,没有切割磁感线,所以没有感应电流产生.当线圈平面与中性面垂直的瞬间,ab和cd的速度方向垂直于磁感线,穿过线圈的磁通量变化最快,产生的感应电动势最大
三:Em=2Blv或Em=BωS
带入数据得 Em=6.28×10∧-2 V
四:e=400sin314t V
Im=Em/R=0.2A

五:KL边与磁场方向成30°角时,线圈平面与中性面夹角为60°,此时感应电动势为e=Emsinωt=Bsωsin60°,电流方向为KNMLK

一见班主任,我就喜欢上了他.年轻,热情,富有朝气,而且弹得一手好吉他.
那一年,他刚从师大毕业,怀着年轻人的梦想立刻投入了工作.我们报到时,他始终微笑着,不厌其烦的回答我们提出的所有问题.这让一开始对陌生环境有些不适应而显得有些紧张的我渐渐放松下来.
他教我们语文.第一天给我们上课,他没有像其他老师一样抱着厚厚的书本和教案,他什么也没拿.起立问好后,他开始自我介绍说:“我叫曹春阳,曹操的曹,春天的春,太阳的阳.”边说边用粉笔在黑板上写了三个大字“曹-春-阳”,接着继续说道:“我希望能像春天的太阳一样给大家带来温暖和希望.”大家一听立刻鼓起掌来.
接着他给我们提了三个问题:1 喜欢不喜欢学语文?2 为什么喜欢或不喜欢?3 怎样学好语文?大家一听立刻议论起来.等大家讨论十几分钟后,他开始提问.提到我时,我思考了片刻然后说:”我非常喜欢学语文,不仅因为语文关系到我们母语的发展,每个中国人都要自觉的学好它,用好它,而且语文和我们日常联系很密切,我们的言谈举止都离不开语文,语文就像盲人的手杖,猎人的火枪一样是我们学习其他科目必不可少的.而我爱学语文还有一点,那就是课本里有很多文学作品,它让我陶醉,让我的心灵获得解放,自由飞翔.”
“很好.”他一边带头鼓掌,一边示意我坐下.“正如蔺间同学说的,语文不仅是我们生活所必不可少,而且我们可以学到不少知识,和做人的道理,然我们的生活更加丰富多彩.大家是不是一定要把它学好呀?”同学们一起喊道:“是.”
“至于如何学好语文嘛,”他顿了一顿然后说,“我认为要做到四个多字,即多读,多背,多思,多写--”就这样短短的一堂课很快就结束了.

请认真阅读下列短文,并根据所读内容在文章后表格中的空格里填入一个最恰当的单词。注意:每空只填一个单词。
Making a public speech is most people’s least favorite thing. The reason is that we are all afraid of making fools of ourselves. The more important the speech is, the more frightened we become .But stop biting your finger-nails. Public speaking is easy. It’s just a simple talking, and you talk all the time. Although I’m basically shy (honest!), I’ve been making speeches and talking on radio and television for more than 30 years. Anybody who can talk can speak in public. Here are some of the lessons I have learned: 
  1. Keep your speech simple. Your audience will leave with one or two of your main ideas, that is to say, most people can remember one or two of your ideas well, one or two, not ten or twenty. So you should prepare one or two of your main ideas well. But if you can’t express what you want to get across, then your speech is not focused well enough. And if you don’t have a clear idea of what you want to say, there’s no way your audience will.
  2. Organize your speech well. No matter how long or short your speech is, you have to organize your speech—how you are going to open or begin, what major points you want to make and how you’re going to close or end. Because a strong close is very important and critical(关键的): the last thing you say is what your audience will most likely remember. If not, they will be confused.
3. Keep your speech not long. The standard length of a speech is usually 12 minutes. Most people can’t focus their attention on one thing for too long time, which will make them tired and lose their interest. If you pay no attention to your audience’s reaction(反应),the audience will get bored. Of course, your speech proves a failure.
Following these suggestions above, you can make a good speech in public, and you will be an excellent speaker, I think.

One night about nine o’clock, Dr. Eyck, a surgeon, had a phone call from Dr. Haydon at the hospital in Clens Falls. The surgeon was asked to go there at once to operate on a very sick boy who shot himself while playing with a gun.
The doctor was soon on his way to Clens Falls. It was 60 miles away. And it was snowing heavily in the city. The surgeon thought he could get there before 12 o’clock.
A few minutes later, the doctor was stopped by a man in an old black coat. Gun in hand, the man ordered the doctor to get out. Then the man drove the car down the road, leaving the doctor in the falling snow.
It was after 2 o’clock in the morning when the doctor arrived at the hospital in Clens Falls. Dr. Haydon told him that the boy had died an hour before.
The two doctors walked by the door of the hospital waiting room. There sat the man in the old black coat with his head in his hands.

解题思路:知道路程和步行速度,根据公式求出行走的时间,再求出从家里出发的时间.

∵v=[s/t],
∴小红从家到学校的时间:
t=[s/v]=[720m/1.2m/s]=600s=10min,
为了在8:00前赶到学校,必须从家里出发的时间8:00-0:10=7:50.
故答案为:7:50.

一列火车从静止开始做匀加速直线运动,有一人站在展台上从第一节车厢的前端观察,第一节车厢通过他历时2s全部车厢通过他历时6S.求
1.这列火车共有几节车厢?
2.最后2秒内有几节车厢通过他?
3.最后一节车厢通过它需要多少时间?
1、由X=½at²知:位移与时间的平方成正比.
L/Lo=(t/t0)²=(6/2)²=9/1
故,L=9Lo,就是说,车厢总长为9节.
2、设车厢长为Lo
加速度:a=2X/t²=2Lo/4=Lo/2
末速度:V=√[2a(9Lo)]=3Lo
最后两秒的位移:
X'=Vt-½at²
=(3Lo)*2-½(Lo/2)2²
=6Lo-Lo=5Lo-----X'/Lo=5/1
即:最后2秒内有5节车厢通过他.
3、设“最后一节车厢通过它需要时间”为t'.
X''=Vt-½at²
X''=(3Lo)*t'-½(Lo/2)t'²
Lo=(3Lo)*t'-½(Lo/2)t'²
t'²-12t'+4=0
t=[6-4√2]s≈0.34s

smoking is habit that’s closely linked to certain times and places. if you break these links, you can break the habit. the best way of doing this is to avoid the situations where you want a cigarette. if you can’t avoid them, then you will have to fight off the temptation(***). sit down and think about when and where you usually have a cigarette. for example, do you always have one after breakfast? after other meals? in breaks at work? when you are watching television? with friends in the pub? once you stop smoking, these times and places are going to be the danger spots. so work out how you are going to deal with them.
it will also help if you can make new habits to break the old one of smoking. so plan some new activities to replace smoking-things to draw away your attention, things to do with your hands, and different ways to deal with tensions.
some people find it helps if they cut down on cigarettes before they actually give up. it’s one way of preparing for the day you stop for good. but don’t look on cutting down as an alternative to giving up, and don’t do it for more than a couple of weeks at the very most. the danger is that you go back to smoking more than you did before
1. what is the best way to stop smoking?
a. avoid situations where you feel like a cigarette.
b. avoid working with smokers in the same place.
c. sit down and think about the situations where you moke.
d. do not bring cigarettes with you when you take a rest.
2. the underlined part “the danger spots” are _______________.
a. the beginning and ending of a period when you stop smoking
b. the time period when you relax yourself
c. the times and places which link to smoking habit
d. the time when you start smoking
3. which of the following activities can be used to stop smoking?
a. something you are able to do in your spare time.
b. something that might improve your skills.
c. something you do not like to do when you are free.
d. something that might interest you in your spare time.
4. one of the ways to stop smoking is to .
a. give up smoking together with a group of friends
b. reduce gradually the number of cigarettes you have every day
c. increase the time that you spend on other hobbies

根据上面的公式有:
每节车厢所用的时间为[√N-√(N-1)]*t1
则通过前9节车厢所用的时间为:
T=[1+(√2-1)+(√3-√2)+...+(√9-√8)]*t1

第一节车厢经过和全部经过的平均速度应该和经过时间成正比
所以2次平均速度比为1:5
设每节长S 共有N节车厢
有 5*S/4=N*S/20 得N=25
因为 S=1/2*a*t^2
所以从静止开始
时间的平方和位移成正比
16/25=t*2/400 t=8*根号5
所以经历时间是 20-8*根号5

中的第五章第一节图,5.1-3
发电机原理,产生了电流的时候电流方向为什么我判断出来的总是和书相反?请说明判断的过程.还有,为什么中性面的时候电动势最大呢?
关于图的问题:ab的电流方向在甲图中是不是b到a?如果是的话,那么在乙图中电流表为什么往左偏转呢?ab是穿过l环还是紧贴在l环上?
p.s.下面两个问题都明白了,你讲的好清楚啊,
缘法今生1年前1
陋石二 共回答了13个问题 | 采纳率92.3%
以甲图为例 ,磁场线从N到S,就是从左到右,AB边向左转动,易知从左穿过线圈的电场线减少,故补向右的电场线,故伸出右手四指弯曲,大拇指指向右,电流方向你应该知道了吧.
这类问题抓住变化的磁通量是最关键的.
中性面的时候电动势最大:因为E=△θ/△T,在发电机发电过程中,发电机以匀速转动,故考察任何一时 的△T都是一样的.所以E的大小只与△θ有关.中性面时穿过线圈的磁通量最大,但△θ最小,所以是最小,不是最大.
最大是乙图.
那么如何分析得到的最大最小呢?因为,从正面看去,AB就是一个圆点,你画一条穿过AB这点的磁场线,中性面时,速度沿磁场线,依据切割原理,这是切不到的,所以E最小.
而乙图则是速度与磁场线垂直,所以最大.
其实在分析任意时刻都可以将即时速度沿电场线和垂直磁场线分速度,就像x,y轴一样,这样你就可以看出实际切割的速度是多少了.最后祝你物理学得越来越好~如果还有不清楚的,你再补充,我会再来的.
补充:乙图电流表不是往右的吗?
是紧贴,并穿过它贴在K上.

引言
(欢迎新同学到莞中,自我介绍)
多姿多彩与神奇奥秘的生物界
说起生物,相信大家都太熟悉不过了,在我们生活的周围处处存在有生物,哪什么叫生物呢 ――凡是有生命的物体就叫生物.
下面给大家欣赏一些图片(电脑软件).
大家看完这些图片有什么感觉呢 (非常漂亮)
对了,让大家看这些图片的目的只是告诉大家,我们的生物界是多姿多彩.
在我们的地球上曾经出现的生物有五百多万种,现存二百多万种,也正是这些种类繁多的花草树木和千变万化的鱼虫鸟兽,使得我们的地球绚丽多姿,盎然生机.
如果我们仔细观察自己周围,总会碰到不少引人思考的问题,比如:
1.为什么植物的根总是向下生长的呢 (播放视频)
与植物的根相反,为什么植物的茎总是向上生长的呢
2.为什么一粒小小的种子会长成一棵参天的大树呢 (播放视频)
3.平常只是看到动物吃植物,哪有没有植物吃动物呢 (播放视频)
4.动物捕食的花招(拟态),你能在视频的第一幅画面上发现某种动物吗 (播放视频)
5.为什么不同的鸟能织出形状各异的巢呢 (播放视频)为什么蜜蜂能不借用任何工具就能筑成标准的正六边形
诸如此类的问题还有很多,
为什么花草树木的叶子大都是绿色的
为什么蜘蛛能结网
为什么人会思考
为什么人会做梦
为什么子女总是与其父母相似
自然界中的这些纷纭众多的生物现象,看起来十分平常,但仔细想起来却又感到神奇奥秘,饶有趣味.以上所说都是我们平常看得到的现象,如果你在显微镜下观察生物,你会发现更多神奇奥秘的地方:
示图片1:杆菌
示图片2:人的表皮(电子显微镜)
示图片3:白细胞正穿过血管壁
示图片4:黑松花粉粒
好,所有给大家看的这些视频和图片,都是告诉大家,生物界也是充满奥秘的,要想探索生物的种种奥秘,就得跨进生物知识的宝库,去寻求揭示奥秘的知识.那我们的生物课就是带领大家跨进生物知识的宝库,并为大家指路,让大家能更好地在生物知识宝库中遨游.
初中生物我们要学三本生物书(示书本),初一上学期主要学习植物,下学期主要学习动物,初二一学年,我们主要学习与我们自己有关的人体生理卫生.
为什么要学习生物知识
除了刚才我们讲的学习生物可以揭示生命的奥秘外,还有:
个人生活的衣食住行都离不开生物知识.(请同学们自己联系生活实际举例)
国家建设离不开生物知识.物质生产的许多行业都要用到生物知识,农林牧渔,医疗卫生.食品加工不用说,就是采矿和冶炼行业都要用到生物知识.发展先进的科学技术,如遗传工程,基因工程更要用到生物知识.21世纪将是生命科学的世纪,生物技术将对我们人类的生活和生产产生重大影响,以后有时间,我会更详细地为大家解释.
当今世界面临的四大难题(人口,环境,资源,粮食)都与生物知识有关.

寂静的夜晚,月华如水,似嫦娥抛下的轻纱,笼住世间万物.近处的村庄进入甜甜的梦乡,偶尔几声犬吠,飘得很远很远,月光也像随着这声音在起伏飘荡.远处的松林,好像一位娇羞的新娘顶着白纱,静静等待心上人来掀起盖头.夜空中,飘浮着莲花般的云朵,轻盈美丽,几颗星星,调皮地透过云隙窥探松林的心事.

《鱼化石》 诗的第一节中的“跳跃”和”沉浮“能否调换?为什么?

不能,因为“跳跃”是紧接上一句“精力是多么旺盛”的,它相比于“沉浮”更能突出鱼儿生机勃勃,精力旺盛,更使上下诗显得顺畅自然,如果调换后,“沉浮”并无“旺盛”的含义,就无法表达应有的意味,显得突然,不通畅.
哈哈!

设一共有M节车厢,一节车厢长S米,则S=1/2*a*5的平方,M=1/2*a*20平方,5的平方比20平方=1比16,则M比S=16,即有16节车厢.
