30分钟内回答我从来不肯妄弃了一张纸,总是留着——留着,叠成一只一只很小的船儿,从舟上抛下在海里.有的被天风吹卷到舟中的

阳光下,大海闪闪烁烁,似一片水晶,如一块琉璃瓦.
不,不.大海多像蓝色的梦,一碧万顷,激荡着多少希冀,蕴涵着多少秘密……
海的梦,曾出现在我梦幻般的童年里.长辈、书本、地图、银幕……使我懂得了：海富有、广阔、美丽.
后来,我真的见到了海.在那“东临碣石有遗篇”的地方.我已无法具体描绘当时的情景,只记得,大海彻底地把我征服了……一幅波澜壮阔的画面在我的眼前展开,“涛山浪谷,雷击霆碎,有吞天沃日之势”.整个世界仿佛都在翻腾,仿佛都是蓝色的!这时候,我才懂得了：什么叫雄浑,什么叫浩大,什么叫力量,什么叫生机!水珠溅湿了我的面颊,我从海滩上捡回了一只彩贝.啊,这是海的见面礼!
我把它藏在我的心里.有一天,我讲一篇关于海的课文,忘情间,拿出了那只海贝.孩子们传递着,目转神移,如同海面上轻风习习……
海很大很大、很美很美……
我要用我的梦,去播种一片蓝色的希冀.
“老师,海是怎样形成的?它会不会消失呢?”
多可爱的孩子啊,爱梦,更爱寻根究底.
我取来了地图.从黄河、长江、尼罗河、密西西比河、伏尔加河,讲到了校旁边的滠水河、山间的小溪、岩缝的泉滴……
“她们是海的母亲.这是海永远年轻、永不消失的奥秘.”
是的,海的存在就在于汇集.聚涓滴、纳百川,不断地充实自己,永不满足,永不停息!于是,才有这广阔的胸怀,澎湃的气势,激扬的活力!
自然,朋友,孩子们不一定懂得这么深.然而,这难道仅仅是孩子们应该懂得的?我年轻的朋友啊,你的内心不也是一片广阔的海洋吗?那里,蕴藏着无穷无尽的潜力.充实自己吧,用知识、用理想、用信念、用志气,趁风华正茂,要自强不息!这样,你智慧的航标就会闪亮,你的奋进的风帆就会扬起,你就会像大海一样,有献出奇珍异宝的慷慨,有托起万吨巨轮的伟力!
1.我要用我的梦,去播种一片蓝色的希冀.这句话中“我的梦”指-----------,“蓝色的希冀”指----------,“播种”的含义是-------------------------.
2.大海给人类的启迪是什么?请在文中用横线划出.
3.文中写了哪两种海?他们的共同之处在哪里?
——————————————————————————————————————————————————————————————————————————————————————————————————————————————————
4.“我”为什么喜欢大海?
——————————————————————————————————————————————————————————————————————————————————————————————————————————————————
参考答案：
1．“我的梦”是指培育人才,“蓝色的希冀”是指学生们拥有知识后成为建设祖国的栋梁之材,成为祖国明天的希望,“播种”的含义是培养教育.
2．聚涓滴,纳百川,不断地充实自己,永不满足,永不停息!
3．文中写了两种海,一种是真实的大海,另一种指知识的海.它们共同的特点就是：广博、无边无际、雄浑、大气、活力；它们的存在都需要永不停息地充实、汇集.

A Meaningful Visit to Institutes
"Perfect ,wonderful !" Some students summarized their visit using these words with excited expression.
Freshmen together with four teachers coming from Collage of Life Science paid a visit to Zoological Museum And Herbarium in WuHan University and Institute Of hydrobiology Chinese Academy Of Science on Nov 1,2009.
At about 8:20a.m.,all the visitors set off to their first destination—WuHan University.Bus stopped at the gate of Zoological Museum And Herbarium,then they were flocked in.So many specimens of all kinds of animals,such as Felis leo ,Panfbero figris,Ursus arcfos lasiofus,Vulpes Vulpes fschiliensis,Chuanchia labiosa Herzenstein and so on .As for some freshmen,the most attractive were tow dead baby –a boy and a girl,they have been being preserved for several years.So serene they are!
About 35 minutes later,these visitors went to their second destination---Institute of Hydrobiology Chinese Academy of Sciences.When walking into the exhibition hall,visitors can see many animals without any distances because no glass prevent their sight,they can even smell their smell—a little odour suggesting that they were living lives at one time.Chinese sturgeon Sawshark and many precious fish are palpable.These fish are keeping their last pose .That is eternal!The last destination was Baiji Dolphinarium."QiQi",a male baiji that had been in captivity for 22.5 years,dying naturally of old age is now on show in a notable place,also they can see wattle-necked soft shelled turtle and some skeletons.Visitors were luck enough to see a special animal—Yantze Finless Porpolses,the only living animal they have seen this morning in these institutes.
When asked their feeling,some students said,"Today's visit is an important visit in our lives.We had never been to professional institutes before,so the strikes in our hearts are deep and heavy." One student also said,"Now I know how wise I was when I chose to study biology!I'm ready to study hard in the coming future.It's a meaningful visit!"

功率等于工作总量除以工作时间
工作总量W为克服重力做功 9m^3 * 1000kg/m^3 * 10N/kg * 10m = 9 * 10^5J
工作时间是30 * 60 = 1800s
所以功率P = W/t = 500w

1度

1.P=密度*10N/kg*H=1600pa
2.V=4*100=400立方厘米.密度＝G/V=25000kg/立方米
3.F浮＝密度*10N/kg*V排＝4N
4.P=F/S=(G容+F浮力的反作用力）/S=8000pa

《错也是对》
小时候,父亲常教我写毛笔字,每当我写到一半,为其中一笔不满意,而懊恼迟疑,父亲总会安慰我：
“上一笔没写好,可以用下一笔去救.练字的人,不但要会写好,还要懂得救好.因为如果你会救,就无所谓错误了!错也是对!譬如一个人写‘太’字.第二笔写歪,别人认为没办法写好,却见他将最后两笔也改个角度,结果不但漂亮,而且妙极了!”
父亲还说有一次康熙皇帝出巡,到了西湖,灵隐寺的主持求皇帝写副字,康熙原想题“灵隐寺”,但落笔时不小心,将“灵”字上面的“雨”写大了,下面的纸幅有限,怎么也不可能把灵字写完,旁人都捏把冷汗,却见皇帝气定神闲,大笔一挥,改写为“云林禅寺”.那幅字至今仍挂在西湖,大家只觉得笔飞墨舞,是幅好字,有谁会去计较那是写错之后的权宜之计呢
我当时太小,听不懂,直到有一天父亲带我去看漫画家表演---只见台上挂着大张白纸,漫画家邀观众上去,随便画几笔,然后立刻根据那几笔,改成一幅画.有些观众存心找麻烦,故意东勾一圈西画一条,大家怎么想都认为画家会被难倒,却见画家略一思索,就解决了问题.
我开始了解,这世上一般人认为错的事,不见得就是错,有些人不但能将那错变成对,而且对得比别人的对还要好.
所以在中学,我试着在作画没有灵感时,把纸摺皱,摊在地上看那折痕,前看、后看、左看、右看,居然能看出许多美丽的山峦与川流.
后来在大学教课,我也常将纸随便‘团’一下,丢在桌子上,让学生运用想象,去寻找美的造型.我发觉用这种方法创作出的画,常能打破自己惯用的格式,开展出新的面貌.尤其喜爱临摹的学生,往往能因此而脱离古人的槽臼.
我更发现,有时候在作画之前想要使用宣纸,不小心拿错了纸,却很可能因为纸不同,产生许多意外的好效果,远非平日所能想见.
如此说来,那错,不也就是一种对了吗?
最近,有位朋友得到一个新工作,但是犹豫不决,便打电话问我那选择对不对.
“让我讲个故事吧!”我说：“某人去水果摊买香瓜,一眼看见葡萄不错,价钱更合理,便改变主意买了葡萄.但是回家打开盒子,发觉葡萄很酸,又转回摊子,换成香瓜.另有个人碰到相同情况,但是懒得回去换,顺手将葡萄扔进垃圾箱.还有一个人,碰到这情形,居然把葡萄打成汁,加些糖,成为不错的葡萄饮料.他甚至想再去买些这种别人不要,而特别便宜的
葡萄酿成酒呢!”
“谁的选择错了?”我问他：“可能谁都没有错!但是有人及时回了头,有人什么水果也没吃,又有人将那错误变成了完美.对于有毅力、有恒心,只要认定方向,就坚持到底的人,许多必败都成了必胜.如此说来,既然你认为那工作可以发挥,又何所谓对不对呢?”
从写毛笔字、画画,到学国画,我深深领悟了这个由错误中寻对的道理,而用在我的生活中,经过许多坎坷、风浪,一次又一次地证明父亲的那句话：
“如果你会救,就无所谓错误了!错也是对!”

问题：
1.作者的写作思路是什么?
2.谈谈你对“这世上一般人认为错的事,不见得就是错”的理解.
3.摘出全文的主旨句.
4.说说你读了此文之后收到的启示.
答案：
你炒股吗,在炒股你就能感到对了就是错了,错了也是对了,如你昨天买的股票今天跌了,那你错了,不过第三天又涨了,你对了,但你没卖,第四天又跌了,你错了,其实关于对和错我早就研究过,对和错是相对的,使用时间连衡量的,并且在一段时间内大家认为对的,在下一时间段内就有可能是错的,如最早的人认为所有恒星都围绕地球转,现在看来是错的,将来没准又一次证明我们现在的结论又是错的了

曲曲折折的荷塘上面,弥望的是田田的叶子.叶子出水很高,像亭亭的舞女的裙.层层的叶子中间,零星地点缀着些白花,有袅娜地开着的,有羞涩地打着朵儿的；正如一粒粒的明珠,又如碧天里的星星,又如刚出浴的美人.微风过处,送来缕缕清香,仿佛远处高楼上渺茫的歌声似的.这时候叶子与花也有一丝的颤动,像闪电般,霎时传过荷塘的那边去了.叶子本是肩并肩密密地挨着,这便宛然有了一道凝碧的波痕.叶子底下是脉脉的流水,遮住了,不能见一些颜色；而叶子却更见风致了.
月光如流水一般,静静地泻在这一片叶子和花上.薄薄的青雾浮起在荷塘里.叶子和花仿佛在牛乳中洗过一样；又像笼着轻纱的梦.虽然是满月,天上却有一层淡淡的云,所以不能朗照；但我以为这恰是到了好处——酣眠固不可少,小睡也别有风味的.月光是隔了树照过来的,高处丛生的灌木,落下参差的斑驳的黑影,峭楞楞如鬼一般；弯弯的杨柳的稀疏的倩影,却又像是画在荷叶上.塘中的月色并不均匀；但光与影有着和谐的旋律,如梵婀玲上奏着的名曲.
荷塘的四面,远远近近,高高低低都是树,而杨柳最多.这些树将一片荷塘重重围住；只在小路一旁,漏着几段空隙,像是特为月光留下的.树色一例是阴阴的,乍看像一团烟雾；但杨柳的丰姿,便在烟雾里也辨得出.树梢上隐隐约约的是一带远山,只有些大意罢了.树缝里也漏着一两点路灯光,没精打采的,是渴睡人的眼.这时候最热闹的,要数树上的蝉声与水里的蛙声；但热闹是它们的,我什么也没有.

火车受到的重力：
G=mg=5×10的十次方kg×9.8N/kg=4.9×10的十一次方N
火车的牵引力:
F牵=G×0.02=4.9×10的十一次方N×0.02=9.8×10的九次方N
因为火车是匀速行驶(它受到的是平衡力)
所以F牵=F阻=9.8×10的九次方N
因为物体在运动时受到的阻力与它的运动方向相反
所以阻力的方向为水平向后
答：火车受到的牵引力为9.8×10的九次方N
方向为水平向后
你要觉得麻烦,可以自己简化哈

我算的也是那么多,但水的量多啊,225千克去喔,加热时间还那么短,当然要很大功率才行啊.或者题目说了,0度的水?仔细想想,晶体在溶化时是吸热但不升温的、要不要考虑这些呢?

（1）连接BC
∵∠A+∠ABC+∠ACB=180
∠D+∠DBC+∠DCB=180；
∴∠A+∠ABC+∠ACB=∠D+∠DBC+∠DCB
∵∠ABC＞∠DBC,∠ACB＞∠DCB
∴∠ABC+∠ACB＞∠DBC+∠DCB
∴∠D＞∠A
（2）
∵D为BC中点
∴所以S三角形ACD=1/2S三角形ABC
∵E为AD中点
∴S三角形AEC=1/2S三角形ACD
∴S三角形AEC=1/2*1/2S三角形ABC=1/4S三角形ABC
∵S三角形ABC=4
∴S三角形AEC=1
(3)
∵AD⊥BC于D
O是AD上的点
∴OD⊥BC于D
∴三角形OBC的高是OD
OF是三角形ABO、AFO、BFO的高

后来温度会降低是因为升高温度所用的热量在空气中又慢慢散发了啊,当然要逐渐降至室温哦

Can money buy happiness?Various people have various answers.Some people think that money is the source of happiness.With money,one can buy whatever he enjoys.With money,one can do whatever he likes.So,in their minds,money can bring comfort,security,and so on.Money,as they think,is the source of happiness.
But there are still a lot of others who think that money is the root of all evil.Money drives people to steal,to rob,and to break the law.A lot of people became criminals just because they were in search of money.And in the Western countries,there is nothing that can’t be bought by money.Many people lose their own lives when hunting it.
I think that money is essential to life and we cannot do without money.But even though money is necessary to life,it can’t buy happiness.Happiness is not something that can be measured by money.It is a state of mind.One can have plenty of money,with which he can buy whatever he wants,and at the same time he is not happy because he is never satisfied or he is troubled by various kinds of problems.Therefore,although money is necessary for a happy life,it can’t buy happiness.

　　我,喜欢吃芒果,爸爸,喜欢吃芒果,妈妈,也喜欢吃芒果.我们一家三口对芒果可是情有独钟.
　　外婆从外地回来,带来了三只芒果.爸爸把它们放在了冰箱里.
　　几乎没等冰箱的门关紧,我就忍不住打开了冰箱.在柔和的灯光中,三只芒果齐崭崭地摆放在果盘架上,发着青红色的光,透着好闻好闻的香味.显然是十分诱人,可是我还是悄悄地合上了门.
　　妈妈看到了,她从冰箱里拿出一个芒果来,递给我说：“你吃吧.”我接过妈妈手中的芒果,拿在手里有点凉,心却是热的.
　　原来,妈妈这几天喉咙发炎,外婆打电话来说,妈妈的喉咙最近老是犯病,芒果可以去火,外婆带过来是专门为妈的,叫妈吃了它.
　　外婆说芒果能去火,我想芒果还是留给妈妈吃吧.我打开了冰箱的门,又把芒果放了回去.
　　第二天,回到家发现三个芒果已放在桌上了.见我从小房间里出来,妈妈说：“你怎么没吃呀?今天我们分吃了吧.”妈妈用沙哑的喉咙说.
　　她把一个递给我,她拿了一个,给爸爸留下一个.
　　我拿了芒果进入自己的房间,抚摸着它滑溜溜的表皮,好舒服.我把它举到了鼻子上嗅嗅,好香啊.我没有吃,随手把它放在了书桌旁.
　　晚上作完作业,该是睡觉的时候,伸个懒腰,我又看见这个芒果了.耳边似乎又传来妈妈的咳嗽声,我想还是留给妈妈吃吧.
　　我打开了冰箱的门——另两个芒果依旧在灯光下发散着柔和的光芒.
　　——这时,一股怦然心动的感觉从我的内心深处深深地迸发出来,流遍了我的周身……——这时,我也才明白,芒果,一个都没有少……

设在距离甲地 x 公里处 汽车卸第一批客人,返回接第二批客人.
此时 第二批客人距离甲地
[x/40]*8 = x/5
汽车与第二批客人间的距离 4x/5
从汽车返回开始计算时间,与第二批客人相遇所需要时间为
(4x/5)/(40+8) = x/60
此时第二批客人又进一步前进的距离为
(x/60)*8 = 2x/15
第一批客人下车后前进的距离为
(x/60)*8 = 2x/15
汽车与第二批客人相遇到时,
第二批客人与甲地距离为
x/5 + 2x/15 = x/3
第一批客人与甲地距离为
x + 2x/15 = 17x/15
则为了两批客人恰好同时到达
(100 - 17x/15)/8 = (100 - x/3)/40
25/2 - 17x/120 = 5/2 - x/120
16x/120 = 25/2 - 5/2
2x/15 = 10
x = 75
则以第一批客人的时间来计算,共需要时间
75/40 + (100-75)/8 = 25/8 + 25/8 = 25/4 = 6小时15分
因此 为了下午4点到达乙地,则需要在上午 9点45分出发

仙人掌类的花特别艳丽,我特别喜欢.它不仅花大色美,而且花瓣有金属光泽,给人以难以忘却的印象.它们的花期大多短促,这就更使它蒙上一层神秘的色彩.其花形态结构变化多,有菊花形、星形、海盘车形、蝶形、漏斗形、烟斗形、花篮形、叉形等.仙人掌的花大,且有轻微香气,真是色香味俱全.

Spring Is Coming
Spring is coming.What a nice season!The weather is getting warmer and warmer.The flowers are coming out.How beautiful the world is!Look around,the sky is blue and the leaves on the trees are turning green.The sun is shining brightly and the air is so fresh,now everyone takes off his warm coat and is more active than before.We all have good feelings.I must say,be careful not to catch cold again.A good beginning is half done and it’s the first season in the year.We must make the best use of our time and catch every second to work and study.Do you think so?

可知在前一个阶段内行驶的距离为:
90*20/60=30千米.
在后一个阶段内行驶的距离为:
72*10/60=12千米.
则汽车在这30分钟内行驶的平均速度为:
42/(30/60)=84千米/小时.
如果从公式计算的话,就是:
S1=v1*t1=90*20/60km=30km,
S2=v2*t2=72*10/60km=12km,
则S=S1+S2=42km,
t=30/60h=0.5h.
则平均速度等于:
v=S/t=42/0.5km/h=84km/h.

可将他看成2部分,20cm高一部分,30cm高一部分,体积比是2:3,30cm用18分钟,20cm的应该用12分钟,实际用了3分钟,体积比为（12-3）：12=3:4

I wish you are happy everyday in your entire life （在整个一生中）///in your rest of your life （在你剩下的日子里）

　　启动老太太家门前,挂着一只红绿相间的小笼子,里边住着一只活泼的小鹦鹉.
　　小鹦鹉很美丽,它有着一身像彩虹一样的外衣.嘴巴是红色的,流线形往下弯下去,像一个小勾子.张开嘴,便能看到它那可爱的、小小的、粉嘟嘟的、圆圆的小舌头,在“嘴巴剧场”里跳“芭蕾舞”呢.小头是桔色的,在那儿一动!一动!可机灵啦!从它的头部慢慢向身体看去,非常自然地从桔色变为金黄色,从金黄色又变成绿色的.羽毛很光滑,在阳光下一闪一闪发亮,可好看啦!它尾巴上的羽毛很长,是紫色的,走路时,小尾巴一扭一扭的,很好玩,非常滑稽!看着,我越发喜欢起这只小鹦鹉来,拉起妈妈的手来到小笼子边.我盯着它,它也盯着我.“妈妈,它怎么不叫呢?”看了好半天,它就是不叫一声.“等会它……”“叽叽!叽!”妈妈还没有说完,它就嘹亮地叫了几声,吓得我一哆嗦,妈妈笑话我说：“你真胆小,不就是一声鸟叫吗?”妈妈刚说完,“叽叽!”“哎哟!吓死我了!”一声响亮的鸟叫也把她吓了一跳.“你不是也很胆小吗?还说我!”我眨着眼睛,调皮地对妈妈说.我又问妈妈：“你说这只鹦鹉从哪里来的呢?”“我怎么知道呢?你要去问奶奶的哇!”奶奶告诉我,这只鹦鹉飞到了舅爷爷的脚上,就把它捉住了,买了一个笼子,就把它放在里面了!原来是这样,那它从哪里来的呢?谁也不知道啦!
　　小鹦鹉,你是如此活泼;如此可爱;如此机灵……让人们把你那灵动的身影,永远刻在心中!
