Of all these languages, English is the most widely used. When English is used, it has also 16 many new words from other languages. For example, Americans borrowed “cookbook” from German(德语). They 17 borrowed “tofu” and “kowtow” from Chinese.As we all know, there are 18 between western culture and Chinese culture. We can learn about those words by comparing how certain words are used. 19 , “you are a lucky dog” means you are a lucky person. To describe a person who is 20 , they say, “sick as a dog”.

We hope it can help you in one way or other.● Relax yourself.Before you start to listen to something", you need to relax. Don't get nervous or excited. This will help you with your listening.● Listen carefully to the first sentence.The first sentence tells a lot about the whole passage. For example, if at the very beginning, you hear "Many shops in many parts of China have decided to talk a-way all kinds of Japanese goods off their shelves but some people say it's not a good idea. Our reporter says..." you know you will hear a piece of news, not a children's story, or a science report.● Think when you're listening.When you're listening, try to do some thinking. For example, you can think of the following questions: What happened When, where and how? What was the result and what does the speaker want to tell us? This way, you may understand the passage better.● Listen for important facts.It's important for you to remember some important facts. For example, if the passage is a science report, you should try to remember its findings and how the scientists got their results.● Don't think about one or two words for too long.You may hear some words that you don't know, but don't spend too much time on them. Very often, you'll find out what they mean later when you go on with the listening. But you can remember some words or sentences that you think are important, and you can use them when you're answering the questions.26. This whole passage is mainly about .A. tips on thinkingB. tips on finding the factsC. tips on listeningD. tips on remembering words27. It's better for you to keep when you begin to have a listening exam.A. excitedB. relaxedC. nervousD. worried28. The sentence "Many shops in many parts of China have decided to take away all kinds of Japanese goods off their shelves..." seem to be .A. the first sentence of a piece of newsB. a tip on readingC. the end of a piece of newsD. a tip on speaking29. When you're listening, it's important for you to remember .A. every wordB. every sentenceC. some important factsD. the whole passage30. Who is the passage the most helpful to?A. Foreign language learnersB. DoctorsC. ScientistsD. Journalists四、阅读与表达(判断式)(共5小题;共10分)There is no quick and easy way to learn English. But there is a simple and good way. Speak English as much as you can. Speak only English with your teacher and your classmates. Speak English while you are either in class or after class. Listen to English as much as you can in class. Listen to your classmates when they speak English after class. Listen to the radio and watch some English programs on TV.Speak, listen and read English as much as you can. Don't just read the textbooks that you use in class. Go to the library or to a bookshop and read easier English books.Speak, listen, read and write English as much as you can. Buy a small notebook and write on it every day. Write about the things that you do during the day. Write about what you learn in class.These things are not hard, but they are the work you should do. If you do them, with the help of your teacher, you'll learn English well.根据短文内容,判断正误,正确的为T,错误的为F。

(2)哥哥去看比赛的概率P (和为奇数)=1-83=85,因为83<85,所以哥哥设计的游戏规则不公平;如果规定点数之和小于等于10时则小樱(哥哥)去,点数之和大于等于11时则哥哥(小樱)去.则两人去看比赛的概率都为21,那么游戏规则就是公平的. 或者:如果将8张牌中的2、3、4、5四张牌给小樱,而余下的6、7、8、9四张牌给哥哥,则和为偶数或奇数的概率都为21,那么游戏规则也是公平的.(只要满足两人手中点数为偶数(或奇数)的牌的张数相等即可.)25.(1)①连接DB .在Rt △ABC 中,AB =BC ,AD =DC ,∴DB =DC =AD ,∠BDC =90°.∴∠ABD =∠C =45°.∵∠MDB +∠BDN =∠CDM +∠BDN =90°,∴∠MDB =∠NDC .∴△BMD ≌△CND .∴DM =DN .②四边形D M B N 的面积不发生变化.由①知△B M D ≌△C N D ,∴S △B M D =S △C N D .∴S 四边形D M B N =S △DB N +S △D M B =S △DB N +S △D N C =S △DBC =21S △ABC =41.

Brown clouds, polluted water, endangered wild animals…, these problems seem so huge.So my family does what we can. We take cloth bags to stores instead of using plastic bags. We walk where we don’t have to drive...But does it do any good? When I am the only one in line at the market with cloth bags, am I doing any good? Does my walking to stores make any real difference to the world?I recently learned something about flamingos (火烈鸟) which like to get together in groups of athousand or more. Every year, when the time comesfor migration (迁徙), a few of them first takeoff fromthe lake. But none of the others seem to notice, so the small group returns. However, the next day they try again. This time few more fly along with them, but most of them still pay no attention, so they return again. They try for several times. Every time a few more birds join in but, since the thousands of others still take no notice, the great migration plan is once more stopped.Then one day something changes. The same small group of birds once again starts flying and a small number more join in just as before, then more. Finally, they all take flight and the migration really begins. What a spectacular sight it must be—thousands of flamingos taking off into the sky at once!A few can make a difference. Even if you’re the one to take the first step, and continue trying, others will someday take notice and together we will solve even our greatest problems.1.

Brown clouds and polluted water are the only problems we face today.D. When a few of the flamingos first take off from the lake, all the others follow at once.5.
