这个!求分啊!

Your hearts are beating with the Olympic cheers!
With your enthusiasm,the world become harmonious.
Your sweat is shining like a superstar!
Everyone dedicate a piece of love,the world is full of happiness.

首先计算所有可能的分配：每个岗位至少一人,说明3个岗位是1人,1个岗位是2人.这个含有两个人的岗位有4种可能.现在假设a有2人,则分配是5C2*3A3=60种,所以全部分配是60*4=240种.
1.甲乙同时在a,情况有3A3=6种,概率是6/240=0.025
2.甲乙不在一起,这种情况可以先算甲乙在一起的概率然后用1减,甲乙在一起的概率是0.025*4=0.1,所以不在一起的概率是1-0.1=0.9
3.这道题应该求得期望吧,一开始算了,a岗位有两个人的情况是60种,所以有一个人的情况是240-60=180种,期望=（60*2+180*1）/240=1.25人.
好久不做,错了的话别笑话我

解题思路：歌声要从卫星传到地球，就要加载在电磁波上，因为卫星和地球之间有一部分是真空的，真空不能传声．

《微笑北京》的歌声要从卫星传到地球，要经过一部分真空地段，需要加载在电磁波上．
故答案为：电磁波．

点评：
本题考点： 电磁波的传播．

Several years ago, we have been immersing it in the happiness of winning 29 sessions of right to host the Olympic Games of the Olympi If I am an Olympic Games Volunteer
c Games all the time. 2008 has already walked close to us quietly, I think what I should do something for her.
I am a middle school student now. I should make more efforts to learn English well. As 2008 Olympic Games ,I will talk to the friends and guests in all corners of the country in the capacity of young man of new era of China. I represent China. I am a master of China. I will discuss with the foreign guest animatedly in fluent English. The ones that describe China are beautiful , Leave a good impression on the foreign guest.
If I am an Olympic Games volunteer, I will draw the beauty and cleaning in Beijing personally. I will land on the streets and lanes of Beijing, will make a contribution for her cleaning, even insignificant. But I will prove my compliment with my my action.
From now on, I should redouble efforts to study. Look forward to becoming an outstanding Olympic Games volunteer in 2008!

因为总有个岗位是2个人的,所以先分好组.分组的组合数C52（5是下标,2是上标）=5*4/2=10,即2个人在一组的情况有10中可能.这样5个人分就成4组了.
有4个岗位,所以排列数A44=4*3*2*1=24,故总共的分配方法数目为C52*A44=10*24=240种.甲乙在一组且在A岗位的情况有A33=3*2*1=6种（甲乙放在A岗位,其他3个岗位人随便换）.所以甲乙同时参加A岗位的概率为 6/240=1/40.

解题思路：由于甲不能从事翻译工作，甲比较特殊，因此需要从甲入选和不入选来分类，不选择甲的情况共有A₄³，选择甲时，需要先选出两个人和甲组成三个人，在使甲在除去翻译工作之外的两个工作中选一个，最后另外两个人再进行排列，相加得到结果．

∵从5名奥运志愿者中选出3名，
每人承担一项，其中甲不能从事翻译工作，
不选择甲的情况：A₄³=24
选择甲的情况：C₄²A₂¹A₂²=24
总共24+24=48
故选C．

点评：
本题考点： 排列、组合的实际应用．

考点点评： 本题考查分类计数原理，是一个有限制条件的问题，注意根据有限制条件的元素进行分类，注意做到不重不漏．

因为我掌握不住五年级是什么水平,尽量写简单点吧
If I am a volunteer
The Olympic Games will be held this year.I am so excited and I think the games will be interesting and also fascinating.But now,the important is,how should we do with the Olmpics if I am a volunteer?To solve the problem will be extremely difficult,because nowadays lots of people devote themselves to society and you can not hold an opportunity easily.So just try my best.
We can go to the English Corner to help them to send some DIY newspapers and go to the neighborhood to tell the stories or history about Olmpics to the people who are curious to learn.Also,we can go on the streets to find the problems such as putting away the trash anywhere,saying out the impolite words.That will be meaningful.I am sure that I will succeed.Believe it,do it!

Dear David,
Hello! I’m Li Hua, a student from Mingqi High School of Shanghai. As I’ve always been interested in charity, I’m writing to you in the hope that I could be given the 2,000-yuan fund to carry out my project to help children in poverty-stricken areas.
My poverty-relief program is divided into three parts. In the initial stage, I’ll try to purchase textbooks for subjects such as English and Maths. Given that new books are usually expensive, I’ll be on the look-out for good-quality s econd-hand books. The second stage of my program is to recruit high school students who have a strong desire to help pupils in poor areas. Surely they should be armed with relative knowledge to be qualified teachers. Lastly, we will set out for primary schools, which are selected and contacted in advance, to carry out our program.
As to how to allocate the money, I’d like to use 1,000 for textbooks, and the rest to pay for the travelling fee of volunteers.
I am looking forward to your reply, thanks!
Yours,
Li Hua

Bidding for the Olympic Games,in a way,an image-creating undertaking.The first and foremost thing is to let people fall in love with the city at first sight,attracting them by its unipue image.What image does Beijing
intend to create for itself once it has the opportunity to host the 2008 Olympics?
It is known to all that the Beijing Municipal Government has already set the theme for the future games:New Beijing,Great Olympics.For me,the 2008 Olympics will be a great green Olympics illuminated with two more special colors,yellow and red.
First,yellow is a meaningful color.The Yellow River is China's Mother River and the descendants of the Yellow Emperor.This color has a special origin and great significance for the Chinese people.Beijing is the capital of New China and previously the capital for nine dynasties in Chinese history.So,yellow will naturally add splendor to the 2008 Games.
Secondly,the 2008 Olympics will be a red pageant.Red is another traditionally cherished color for the whole country.We adore red.On big occasions,we like to decorate our homes in red.It is the color of double happiness,representing joyous moments,auspiciousness,enthusiasm and prosperity.Red is one of the most suitable colors to describe the future of Beijing .Beijing ,together with the whole country,is becoming more and more prosperous in the process of modernization.Should the 2008 Olympics be held in Beijing,the whole city will be a sea of red :the red torch,red flags,red flowers,and the radiant faces of millions of joyful people.
Above all,the 2008 Olympics will be a green Olympics.Adding a green ingredient is essential in creating an appealing image,as we can't deny the fact that Beijing,at the moment,is not as green a city as what we like it to be.Striving for an environmentally appealing city has become a central task for all the citizens of Beijing.Big efforts have been made in pollution control,replanting and beautification of the city.According to a project entitled" The Green Olympic Action Plan",between 1998 and 2007,Beijing,we have invested 100 billion RMB in preserving and protecting the environment.Some 12.5 million trees and over 1 million acres of grass will be planted along the Fourth Ring Road.By then,the city's green area will make up 40% of its total.The city will also dredge its reservoirs used as a water supply to Beijing residents,controlling industrial pollution and moving out the 200 factories presently located within the city proper.
Certainly,all of this is no easy task.But I am sure that all of us have confidence that we will realize these green goals.For now we have the full support and participation of the environmentally conscious citizens.Each
citizen is showing great concern for every one of the steps the city government takes.As the saying goes,United,we stand,and a green Beijing will be achieved.
When our aspiration becomes a reality,it will be a unique Olympics." New Beijing,Great Olympics"; will be weaved of these three superb colors:yellow,red and green.
Let us welcome it and look forward to it!

指导老师：顾萌 随着第二十九届夏季奥运会的步伐临近，我渴望成为一名奥运志愿者的欲望越来越强烈了。终于有一天，我收到了奥组委的通知：我被录取为北京奥运会的正式志愿者，我激动地跳了起来，真是太棒了。 2008年北京奥运会即将开赛，我按捺不住内心的激动。终于我渴望的那一天来临了，我穿上了崭新的工作服，戴上工作证，迈着轻快的步伐走向赛场。柔和而明亮的灯光照在我身上，我和其他工作人员连忙开始布置，我们认真地擦着椅子、扫地，为了使中外运动员更好地发挥水平，我们调整灯光强度，保持室内温度，准备矿泉水等等。 各国的运动员进场了，他们满意地看着周围一切设施，比赛中都发挥出自己最好的水平，拿到自己满意的成绩。突然，一名运动员下楼梯不慎摔倒骨折了，身体在地上痛苦地挣扎，我赶紧把好她背到医务室，给她轻轻地擦拭伤口，然后让医生给他包扎、治疗，直到把骨折的手臂用石膏固定后，我悬着的心终于放了下来，那名女运动员感激地流下了眼泪，不停地用英语跟我们道谢。 …… 总而言之，我当奥运志愿者的目的有二点：一是为了锻炼自己，敢用英语和外国人对话，帮助他们。二是为了服务人民，只要别人有困难，我一定会热心帮助，以良好的形象迎接世界友人，展现出我们中华民族的优秀品德和礼仪。 可惜的是，这只是一个美好的愿望而已，能否实现，我不能预测，但是我知道只要一个人不懈地克服各种困难，那些我们梦寐以求的愿望就会一点儿一点儿靠近，最终将会实现。

解题思路：两个闹钟至少有一准时响包括三种结果，即两个都准时响，只有一个准时响，．而它的对立事件是两个闹钟都不准时响，两个闹钟都不准时响的概率是（1-0.8）（1-0.9，由对立事件的概率公式得到结果．

∵两个闹钟至少有一准时响包括三种结果，即两个都准时响，只有一个准时响，
而它的对立事件是两个闹钟都不准时响，
两个闹钟都不准时响的概率是（1-0.8）（1-0.9）=0.02，
由对立事件的概率公式得到
∴至少有一准时响的概率是1-0.02=0.98
故答案为：0.98．

英语作文:参加志愿者活动的一次经历.

What can I do for Beijing 2008 Olympic
I will be sixteen years old when 2008 Olympic being held in Beijing.I have many dreams about it,I want to be a translator to work for foreign athletes.I want to be a guider to show Beijing to foreign visitors.I also want to be a athlete to win honor for China.I want to be…
But as a pupil,what can I do for it now?First,I should make Beijing’s environment to grow better,I can save water,electricity and paper,place garbage by classifying it,actively spread the knowledge of environmental protection.Second,I should enhance my ethic ,safeguard the nation’s honor and take good care of public facilities.Third,I should work hard for my lessons,especially in English.Fourth,I should do exercises every day to improve my health.
I am proud of a Chinese.I hope my country to be much stronger.I look forward to 2008,I will say to the world aloud:Welcome to Beijing.

(1).先算总的：从5个人中先选4个有C54（5下4上）,然后这4个人进行排列有A44种,剩下一个人再插到这4个位置中有4种所以总数有C54*A44*4=480种方法
再算甲与乙在A中的：把甲乙看做一体,占领A位置,剩下的3个人再排位置,有A33种方法,因为总的里面的第一步包括了先排除甲的情况与先排除乙的情况的可能性所以此时甲乙须在排列一次有A22种情况,则甲乙在A中有A22*A33种
所以综上所诉：P（甲乙在A中）=A22*A33/C54*A44*4=1/40.
(2).这是甲乙在A的情况,则在BCD中都有1/40,则P（甲乙在一起）=1/10
所以对立事件P（甲乙不在一起）=9/10

年奥运会我要做一名志愿者I want to be a volunteer of beijing olympic games. I realized the time flies.I must study english very hard. Because English is very useful and it is very important. And to be a volunteer of the olympic games is good for myself too.I can make some friends from different countries and learn more about sport,about olympic. But the first thing to perpare this is study hard, I am confident i will to be a good volunteer and I will show the world:our country and our cities are so perfect in the world.

（1）记甲、乙两人同时参加 岗位服务为事件M ,
那么P(M)= A(3,3)/[C(5,2)A(4,4)]=1/40
即甲、乙两人同时参加 岗位服务的概率是1/40 ．
(2)求甲、乙两人不在同一个岗位服务的概率；
记甲、乙两人同时参加同一岗位服务为事件N ,
那么 ,P(N)=A(4,4)/[C(5,2)*A(4,4)=1/10
所以,甲、乙两人不在同一岗位服务的概率是
1-P(N)=1-1/10=9/10．
