1.2下八单元 篇一

春姑娘悄悄地来到我们身边,她留下了脚印。

柳树从直立的茎上伸出纤细的枝条。小草用它的小脑袋从土壤中探出头来,充满活力地看着它。

天气既不多云也不晴朗。起初很冷,但同时很暖和。一会儿,微风习习。再过一会儿,就要下一磅雨了。春天是哭和笑的时候。春天擅长扮演女人。树叶从树枝上发芽,稀疏地散落在地上,黄色、黑色和浅绿色。它看起来很不愉快,但是几天后,它变成了一个浓密的绿云,一幅星星和野花的挂毯。厚厚的灰色乌云压在你的额头上,自然会让你感到闷闷的,但转眼间它们就会变成轻烟,像薄纱,像清脆的小雨。新婚的紫燕经常来我家做客,用柔和的语言窃窃私语,互相讨论。我知道他们一定喜欢我的屋顶梁。事实上,几天后,他们开始用泥土和草筑巢。在远处,我不知道它是画眉、云雀还是黄鹂,试图说些新的东西。强烈的涩味,不自然地,一声一变,就像苦涩的吟游诗人在掂量他的诗句。绿叶中的紫罗兰喃喃自语,芬芳草丛中山谷百合的低语,春天旁迎春花的浅浅微笑,你听不见吗?我听得很清楚。他们都盛装打扮,只等春天女神揭开绣花窗帘,然后他们就一个接一个地玩。现在他们有点浮躁和不耐烦。春天已经准备好了。春天在等待。春天是温柔的,春天是坚强的,春天是浪漫的,春天是一年的开始,一切都是新的。

自然美是不可触摸的,时不时地出现和消失。春天的鸟儿在树枝上歌唱,流动而悠扬,使人们不安的心再次迷失。春花在狂喜的土地上,美丽、优雅。

张开双臂,平静地触摸大自然的春天,感受春天的美丽。

参考答案

一、填空题

1. 3

2. 60

3. 甲

4. 56

5. 334π

6. 2

7. 5

8. 3

9. a=0.005

10. 13

11. 59

12. -560

13. 18

14. 3964

二、解答题

15.解:(1)由于甲、乙两组各有10名工人,根据分层抽样原理,要从甲、乙两组中共抽取4名工人进行技术考核,则从每组各抽取2名工人.

(2)记A表示事件:从甲组抽取的工人中恰有1名女工人,则

P(A)=C14C16C210=815.

(3)Ai表示事件:从甲组抽取的2名工人中恰有i名男工人,i=0,1,2

Bj表示事件:从乙组抽取的2名工人中恰有j名男工人,j=0,1,2

B表示事件:抽取的4名工人中恰有2名男工人.

Ai与Bj独立,i,j=0,1,2,且B=A0·B2+A1·B1+A2·B0

故P(B)=P(A0·B2+A1·B1+A2·B0)

=P(A0)·P(B2)+P(A1)·P(B1)+P(A2)·P(B0)

=C24C210·C24C210+C14C16C210·C16C14C210+C26C210·C26C210=3175

所以抽取的4名工人中恰有2名男工人的概率为3175.

16.解:(1)由题意,前三项系数分别为C0n,12C1n,14C2n,

则C1n=C0n+14C2n,解得n=1(舍),n=8.

(2)设第r+1项系数为tr+1,且设第r+1项系数最大,则

tr+1≥tr

tr+1≥tr+2即Cr8(12)r≥Cr-18(12)r-1

Cr8(12)r≥Cr+18(12)r+1,解得2≤r≤3,且t3=t4=7,

所以展开式中最大项为第三、第四项.

17.解:(1)C36C24=120(种);

(2)C12C48+C22C38=140+56=196(种);

(3)C510-C56=246(种);

(4)C510-C58-C45=191(种);

答:略

18.解:设事件A为“方程a2+2ax+b2=0有实根”.

当a>0,b>0时,方程x2+2ax+b2=0有实根的充要条件为:a≥b.

(1)基本事件共12个:(0,0),(0,1),(0,2),(1,0),(1,1),(1,2),(2,0),(2,1),(2,2),(3,0),(3,1),(3,2).

其中第一个数表示a的取值,第二个数表示b的取值.

事件A中包含9个基本事件,事件A发生的概率为P(A)=912=34.

(2)试验的全部结果所构成的区域为{(a,b)|0≤a≤3,0≤b≤2}.

构成事件A的区域为{(a,b)|0≤a≤3,0≤b≤2,a≥b}.

所以所求的概率为=3×2-12×223×2=23.

19.解:(1)设数学辅导讲座在周一、周三、周五都不满座为事件A,则

P(A)=(1-12)(1-23)(1-23)=118.

(2)ξ可能取值为0,1,2,3,4,5,

P(ξ=0)=(1-12)4(1-23)=148,

P(ξ=1)=C1412(1-12)3(1-23)+(1-12)423=18,

P(ξ=2)=C24(12)2(1-12)2(1-23)+C1412(1-12)323=724,

P(ξ=3)=C34(12)3(1-12)(1-23)+C24(12)2(1-12)223=13,

P(ξ=4)=(12)4(1-23)+C34(12)3(1-12)23=316,

P(ξ=5)=(12)423=124,则随机变量ξ的分布列如下:

ξ012345

P1481872413316124

所以随机变量ξ的数学期望Eξ=0×148+1×18+2×724+3×13+4×316+5×124=83.

20.解:(1)取x=1,有a0+a1+a2+…+a2n=(1+14)2n=625256,解得n=2,

此时a3=C34·(14)3=116.

(2)由题意知:ak是a0,a1,a2,…,a2n中的最大项,ak=Ck2n4k,ak-1=Ck-12n4k-1,

所以akak-1=Ck2n4k·4k-1Ck-12n

=(2n)!k!(2n-k)!4·(2n)!(k-1)!(2n-k+1)!

=2n-k+14k(1≤k≤2n,k∈N*),

令2n-k+14k≥1,得k≤2n+15,设小于或等于2n+15的最大整数为M,则

当1≤k≤M时,ak-1≤ak,故a0<a1<…<aM-1≤aM(M=2n+15时取等号);

当M<k≤2n时,2n-k+14k<1,ak-1>ak,故aM>aM+1>…>a2n.所以当2n+15=M时,满足条件的正整数k有2个,即k=M或k=M-1;

当2n+15>M时,满足条件的正整数k只有1个,即k=M.

还香甜地睡着,却被那刺耳的铃声闹醒。“真是的……”我迷迷糊糊地睁开眼,赤着脚跑向了书桌。手机“嗡嗡”地在手里震着,我微眯缝着眼——竟是我定下的闹铃,那上面反复闪动的字:立春。2月4日。

已经是立春了,春天,就这样在早晨,特别地吵醒了我。心情便欢欢喜喜的,仿佛有个小人儿,在心尖尖上闹哄哄地吵着。春天的我,就被注入了鲜活的生命力,疯狂地甩着头发,嘴里哼着歌。我依旧和姐姐在一起向前走,今天还有忙碌的课程,然而心情已经与往昔不同了,这是定理,春天里的人永远获得生机盎然。

风还是有些耍着性子,带着些凶狠地刮着我的脸,慌慌张张间未曾擦干的发,都凝结得紧紧的,怎样也分不开。轻轻地扯那么一下子,还会疼得我呲牙咧嘴。算了,让阳光在某时某刻晒干它吧,就像晒干所有的泪水一样。在书店高高的柜台上,看见了还未放假那会曾留意的一本杂志还在,充满了惊喜。我笑了,咧嘴笑着,买下了它,这大概就叫缘分,所以,我很干脆地买下了它。春天伊始的时候,买下一本和自己有缘的书,文学之路也会开满花朵吧,开满希望的花,生命的花,哦,春天,春天。

4.2下八单元 篇四

人总是会从顶峰陷入到低谷。当我经受挫折时,我总会感觉到有种隐忍的爱。这种爱是神秘无比的,它在无意中才会发觉的。但我知道这种爱一定是来自于母亲的。母亲只有小学文化水平,她没有名人那样博学多才,也没有知识分子那样知识丰富。但她却能用一些朴素而简洁的语言来激励我前进,使我重新找回动力。尽管她的话语不是十分优美动听,但是从她的身上却可以体现到她对儿女深厚的爱。

母亲总会尽她的能力来照料我们。当我淘气的时候,她会用一些可以感化我的事情来劝导我;当我不听话的时候,她会用一颗善良的心来教育我;当我成绩不理想的时候,她会沉住激怒,耐心地安慰我,并告诉我:“人生总会有喜有悲,总会有失败的时候,它不可能是一帆风顺的。如果事事顺利,那么还需要你的努力吗?”从母亲的话语中,我感到母爱是温暖无比的。

母亲是个不善于言辞的人,她总会用实际行动来感化我们。当我赢得快乐的时候,母亲总会和我一起高兴,她希望女儿快乐。只有这样,她付出的汗水才会有收获。她努力让我摆托伤痛,不希望我停留在悲伤的时刻。她经常做些有趣的事把我逗笑,为的就是让我过得快乐。虽然母亲为女儿做的事情不是惊天动地,但在每一件微笑的事中,我都可以感受到母亲那永恒的爱。

母亲像一汪清泉,集汩汩之水哺育儿女茁壮成长。母爱像太阳,能让你在寒冷的冬天也感受到春天的温暖,能让蒙上岁月风尘的情感散发出生命的清辉。母亲把一生的爱都贡献给儿女。她总是无私地奉献,却不求任何的回报。为了儿女,母亲费了多少力气,吃过多少苦。她坚强地支撑这,不向命运低头。然而,她的爱是永恒的。

5.2下八单元 篇五

思绪又拉回到那个阴雨天,天公不作美,小树都被豆大的雨点打得弯腰,而我,还站在学校大厅里犹豫不决:是顶风冒雨回去,还是再......再等等?雨越下越大,看着同学们一个个被父母接走,急得我像热锅上的蚂蚁——团团转。妈妈她会来接我吗?不,现在她正在上班呢,怎么可能……我叹了口气,准备“上战场”这时,眼帘中出现了一个熟悉的身影,啊,妈妈来了,她来接我了!我欣喜若狂地跳下台阶,一个箭步跑到妈妈跟前,同时又疑惑地问道:“妈妈,你不在上班吗?怎么来接我了?”“孩子,看到外面下雨了,我担心你淋雨,就匆匆请了个假,赶过来了。”只见妈妈,头发湿漉漉的,脸上不知是汗水还是雨水,我感动极了,喃喃地说:“妈妈,以后我长大了一定好好疼你!”

瞧,妈妈对我不仅有生活的呵护,还有学习上的关心倍至。一次正攻克数学题的我遇到了一道列方程的题,我苦思冥想就是找不出等量关系,试了一次又一次,看看了一遍又一遍,答案像是在和我捉迷藏,心灰意冷地我开始烦躁不安。这时,妈妈走了过来,她扫了一眼题,说:“再仔细看看,第二句话中藏有重要信息。”我努力使自己平静下来,认真读题,果然成功的揪出了答案,事后,妈妈语重心长地对我说:“孩子,面对困难不应该气馁,不应该灰心,你有实力,何不去努力战胜它呢?困难像弹簧,你弱它就强,你强它就弱啊!”妈妈这番话让我受益终生。

7.2下八单元 篇七

生活,是一个动词,意味着生存,人生中最主要的目的;是一个名词,代表着日子的积累与流逝。如今随着奥运会的成功举办,世博的临近,上海人的生活也变得美好起来,但是生活的内在却不如外表来的那么光鲜亮丽,在成功那个背后,我们失去了很多,只是相对的,我们仍能从另一方面得到回报。即使有些失去的已将成为永远

例如环境,在人们创造各种奇迹和辉煌的同时,环境污染已越来越严重。有时我在想:生活中,不可获缺的到底是什么?是那些闪亮的辉煌事迹,或是倍受关注的世人的目光,抑或是良好的生存环境。在我看来,环境是最重要的。只有保护好了我们的生存环境,我们的生活才能更美好!

高楼大厦的耸立是城市热岛效应的起源;汽车尾气大量排放导致了城市雨水PH快速降低;为了增加农田面积随意砍伐树林,不但没有预期的效果,反而加重了水土流失,被视为得不偿失之举。这些无不都破坏了生态环境,从而影响到了我们的美好生活,并阻碍了向更美好的方向发展。

因此,当前我们应“从我做起,从身边小事做起”保护生存环境。

不只是上海,全世界的人都应有保护环境的意识,让生活更美好!

生活好似在品味咖啡,伴随着苦涩的同时又是甘甜回味;生活好似雕琢,“玉不琢不成器”,只有细心雕刻好这块“玉”,才能耐人欣赏和挑剔;生活更如同磨墨,历经长久地研磨后,可以在生活中留下潇洒的一抹印记!

8.2下八单元 篇八

你们猜猜我的朋友是谁?那就是我的同班同学徐珺妍啦!她有一个一翘一翘的马尾辫,走起路来,一蹦一跳的,两只圆溜溜的眼睛,散发着童年的光芒,白白的小脸蛋笑起来可美了!

我的好朋友很“狡猾”。有一次,她和我一起玩捉迷藏的游戏,先由她来找我。游戏一开始,我就赶紧跑开了,心想一定要找个她很难找着的地方躲起来。四楼的那个凹凸的洞洞?不行,我们玩过的地方。一楼我们班的公共区?不行!咦!有了,女厕所!她肯定想不到。我一口气跑到了女厕所,躲在里面,尽管臭气难闻,但我心里还得很得意,这下子够她找了。果真,我等呀等呀,就是不见她来。我实在憋不住了,就笑嘻嘻地走出厕所想去笑一笑她这个笨蛋。结果,刚一出去,只听一声“曾添!”,我抖了一下,一蹦三尺高,吓死我了!一看徐珺妍正在得意的咯咯地笑。原来,她一直跟踪我到这儿,机灵地躲在厕所旁,就是不进去找我,专等着我出来吓我一跳,你看,她够“狡猾“的吧!

我的好朋友不但狡猾淘气,还会搞笑呢!我记得上次,徐珺妍故意逗我们说:“漆中昊,油中昊……”一边叫着还一边做着鬼脸。结果,漆中昊气得脸都涨得通红,两眼直直的瞪着,像一头正被激怒的公牛,而我们却被笑得肚子痛得不得了。

你别看她这么淘气,但学习上却是顶呱呱的呢!每次老师要不就表扬她笔记写得好,要不就表扬她作文写得好,还有前几天的“英语大赢家”竞赛她还是第一名呢!
