Today we can see that many people are cutting down the trees in the forests. A lot of        lands have become deserts. If we read newspapers, we’ll learn that the forests on the earth are getting smaller       . We are cutting down large numbers of trees        we need wood and farmland. Some scientists say that there will not be any great forests        20 or 30 years.
What will happen if the forests disappear? A lot of plants will die and the animals will      
their homes. In many places the new farmland will soon look        the old desert. Crops will not grow there. There won’t be enough       , and the weather will get hot and dry. If the climate of the earth changes, life will be        for everyone. Our living environment will become       . More and more rich farmland will disappear. We will suffer a lot from both droughts (干旱) and floods.
It’s our duty        the forests well. Everyone should try his best to make a contribution (貢獻) to taking care of the forests. Stop cutting down the trees and make the world greener!

試題分析：這篇文章為我們講述了保護森林，保護樹木的重要性�，F(xiàn)在人們越來越多的砍伐樹木，導致世界上的樹木急劇減少，這對于我們所賴以生存的環(huán)境是極為不利的。文中作者設想了如果沒有了森林我們的世界將會怎樣，最后呼吁我們要盡力的保護好森林。
小題1:考查形容詞及語境的理解。句意：很多肥沃的農(nóng)田變成了沙漠。rich 肥沃的；low 低的；lonely 孤獨的，寂寞的。這里是用來修飾農(nóng)田farmland，所以用rich。故選A。
小題2:考查固定短語及語境的理解。句意：我們知道地球上的森林一直變得越來越少。on time準時；all the time 一直，總是；in time 及時。根據(jù)文意，地球上的森林不斷的減少。故選B。
小題3:考查連詞及語境的理解。句意：我們砍伐了大量的樹木，因為我們需要木材，需要農(nóng)田。根據(jù)文意，這里應是因果關系。故選C。or或者，否則；so 因此，所以。B選項正好把因果弄顛倒了。
小題4:考查介詞及語境的理解。句意：科學家們預言在二、三十年之后將不再有大片的森林。in 用于一般將來時，后跟一段時間，表示在…之后；at 后常跟具體的時間點；on 后跟具體的某一天。故選C。
小題5:考查動詞及語境的理解。句意：很多植物將會死亡，很多動物將失去它們的家。lose 丟失，失去；find 發(fā)現(xiàn)，找到；build 修建，建造。根據(jù)句意，沒有了森林，很多動物就沒有了棲息的場所，所以是失去了家。故選C。
小題6:考查介詞及語境的理解。句意：在很多地方，新的農(nóng)田看起來就像古老的沙漠。look like 看起來像；look up 查閱；look at 看…。根據(jù)句意選B。
小題7:考查名詞及語境的理解。句意：將沒有充足的雨，天氣會變得又熱又干燥。根據(jù)句意，天氣會變干燥，所以是沒有足夠的雨。snow 雪，下雪會使天氣變冷，不符合文意；wind 風，跟后面天氣變得熱、干燥沒有關系。故選B。
小題8:考查形容詞及語境的理解。句意：如果地球上的氣候發(fā)生變化，生活對每個人來說將會變得困難。easy 容易的，不符合文意；happy 高興的，快樂的；跟文意不沾邊；hard 困難的。故選C。
小題9:考查形容詞比較級及語境的理解。句意：我們的生活環(huán)境將變得越來越糟糕。better and better 越來越好；bigger and bigger 越來越大； worse and worse 越來越糟糕。根據(jù)文意可知，沒有了森林，地球的環(huán)境會變差，那我們的生活當然會變得糟糕。故選B。
小題10:考查動詞及語境的理解。句意：保護好森林是我們的職責。It’s our duty to do sth. 做某事是我們的職責。在這個句型中應該用動詞不定式。故選A。

It is said that more than four million people die each year from smoking. That number is frightening.

Yet people around the world continue to smoke. In the United States, about forty-seven million adults smoke. This year, more than 430,000 Americans died of diseases which have something to do with smoking. The American Cancer Society(美國癌癥協(xié)會)says smoking harms the body greatly. It warns that smoking even a number of cigarettes is dangerous.
It’s not easy to give up smoking. However, doctors say you probably will live longer if you do stop smoking. You will feel better and look better. You also will protect the health of family members who breathe your smoke.
There is not one right way to stop smoking, doctors say. Any way can help. You can take long walks or spend time in places where smoking is not allowed. Also, you can eat a small piece of fruit or vegetable instead of having a cigarette. The sooner you stop smoking, the more you’ll reduce your chances of getting cancer and other diseases.
Stop smoking before smoking stops you!
小題1:How many people die from smoking each year?
小題2:What does the American Cancer Society say about smoking?
小題3:Is it easy to give up smoking?

Music is different from songs. Songs express feelings with lyrics(歌詞）, but music with tones (音調(diào)).Unlike songs, music tones in themselves have no specific meanings. Different people may get different things from the same musical performance. Though some music works are difficult to understand, people need music in their daily life because it brings fun to them. Different people like different music: some love classical music, and others take an interest in pop music. Most young people like pop music.
Pop music began in the USA and became popular around the world during the 1950s and 1960s.The best-known early kind of pop music was “rock and roll”. Pop music has taken the place of （取代）native music in many parts of the world. It has caused the number of people for “jazz” music to become much smaller than in the 1950s and earlier and it has now begun to become the most popular. Much pop music is without artistic value (藝術價值), but the works of some pop singers such as the Beatles, Bob Dylan, the groups like Pink Floyd and Crosby are excellent. And there is still great interest in it today. Pop music concerts and festivals are held all over the world.
