Now satellites are helping us to forecast the weather. They are in space, and they can reach any part of the world. The satellites take pictures of atmosphere(大气). So the scientists there can see the weather of any part of the world and how the weather will change.
Today, nearly five hundred weather stations in sixty countries can receive satellite pictures. When they receive the new pictures, they compare(比较) them with the earlier ones. Perhaps they may find that the clouds have changed during the last few hours. This may mean that the weather on the ground may soon change, too. In their next weather forecast, they can tell people about it.
So the weather satellites are of great help to the scientists at the station. In the past they could forecast the weather for about 24 or 48 hours earlier. Now they can make good forecast for 3 or 5 days. Soon, perhaps, they may be able to forecast the weather for a week or more ahead.

2. Changing clouds in the atmosphere means that weather may change.
3. Without satellites, scientists could forecast the weather for 3 or 5 days ahead.
4. Today, every country has its own weather station which can receive satellite pictures.
5. The main idea of this passage is that satellites are now used in weather forecast.
B
This is a tale of two friends — one is blind, the other has no arms. On their own, the two are “disabled”. But together, they are a powerful team that has changed part of their village in North China’s Hebei Province into a rich, green forest. Meet 53-year-old Jia Haixia and Jia Wenqi!
Their story began in 2000, when Haixia, who was already blind in his right eye, lost his left one after an illness. Wenqi lost his arms in an accident when he was just three. Neither could find a job, so the two decided to team up. They rented some poor land and began to plant trees. In return, the local officials paid them a small fee.
Haixia and Wenqi never imagined that they would end up creating an environmental paradise. Their forest now has over 10,000 trees, hundreds of birds and many other wild animals. In addition, it saves the village from river flooding during the rainy season.
When the friends work together, they focus on their strengths not their disabilities. Their day begins at 7 a.m. when the sightless Haixia carries Wenqi across the river to get to their worksite. Since they cannot afford to buy young trees to plant, the two use branches from existing trees. Haixia climbs to the tree-top and with Wenqi’s direction, selects the perfect branch. He then digs a hole and carefully plants it. Finally Wenqi waters the area.
Though hard-working, the men don’t make much money. But as Wenqi puts it, “We stand on our own feet, so the fruits of our work taste sweeter.”
Neither Haixia nor Wenqi cares about money. Together, they already have everything they need — a perfect pair of eyes, two strong hands, and the best friendship in the world!
6. Why did Haixia and Wenqi start working together?
A. Haixia needed someone to help him.
B. They both needed a way to make money.
C. They wanted to improve the environment.
D. They were required to do so by local officials.
7. Haixia and Wenqi’s forest has helped the village by______ .
A. stopping floods in the rainy season B. increasing the number of tourists
C. making the villagers richer D. providing more farmland
8. Why do Haixia and Wenqi plant tree branches?
A. They are easy to get. B. They do not cost money.
C. They can grow very quickly. D. They are preferred by animals.

9. In paragraph 5, when Wenqi says “We stand on our own feet, so the fruits of our work taste sweeter”, he means that “______”.
A. they hope to make the forest even better B. the fruits from their trees are very sweet
C. they are proud not to depend on others D. they are able to do any difficult work
10. What can we learn from this story?
A. Never give up and you will succeed. B. We should help the disabled to work.
C. Try your best when facing difficulties. D. We can achieve more with teamwork.
答案与解析：
Ⅰ. 单项选择。
1. C。本题意为“如果Amy不被邀请的话，我也不会去。”此处考查的是被动语态。此句
是复合句。因主句时态是将来时，从句用一般现在时态表示将来。
2. C。hear sb. do sth. 的被动语态结构是sb. be heard to do sth. 注意不要忘记加to。
3. A。be made of“由……制成”，指能看出原料。
4. B。本题考查“时间段”作主语时，相当于第三人称单数形式，句中since之后，是过去时态，所以主句是现在完成时态。
5. C。as soon as “一……就”; as well as “与……一样”; as long as “只要……”; as far as “同……一样远”。根据题意，故选C。
6. C。考查make a contribution to (doing) sth. “为……作贡献”。
7. D。本题考查带有情态动词的被动语态。
8. D。as long as指“只要”；as soon as指“一……就……”引导时间状语从句；as well指“也”，但放在肯定句的末尾；as well as（doing）指“既……又……”，故选D。
9. A。本题考查“疑问词+不定式”结构作宾语。
10. A。考查say for certain 确切地说。

1. C。句意：他们听说晚会因为考试推迟了。put on穿上；put up张贴；put off推迟；put down放下。根据句意可知用put off。
2. A。句意：——来自连云港的六个学生在江苏省中国汉字听写大赛上获得了一等奖。——真是激动人心的消息！本题考查感叹句。感叹句结构之一是：What＋形容词＋不可数名词＋主语＋谓语。news是不可数名词，前面不加不定冠词。故选A项。
3. A。 根据答语的明显时间标志词ago，可知本题所考时态为一般过去时。故答案为A。
II. 完形填空。
1. C。本题考查被动语态，be called表示“被称为”。
2. B。根据题意关于遥远星球的图片和事实是用VoyagerⅠand VoyagerⅡ发回地球的，故
此处用back。
3. D。由下一句“But it is only twenty cents for each American each year. 可知此处用sounds”更合适。
4. A。本题考查so … that …句型。
5. C。at a distance of 固定用法，表示“相隔”。
6. D。sth.+cost+some money，it takes sb. some time to do sth., sb.+spend/pay …，根据以上动词所需要的主语不同，形式不同，所以此题选D。
5
7. B。for example引出插入语，such as引出同位语。
8. C。put on在此处表示“增加……”（额外提供）。
9. D。本题用spoken这个过去分词作定语表示被动含义。
10. A。a message作主语表示单数，故此处用is。
III. 阅读理解。
A
1. F。从阅读全文及生活常识可知气象卫星主要用来帮助科学家们预报天气情况，并不是有助于他们知道所有的事情。
2. T。从文中第二段“Perhaps they may find that … may soon change，too. ”两句中可找到
该答案。
3. F。从文中最后一段得知如果没有卫星，科学家们只能预测未来1到2天的天气情况。
有了卫星的帮助，他们能准确的预测3到5天的天气情况。
4. F。从文中第二段“Today, nearly five hundred weather stations in sixty countries can receive satellite pictures.”一句中可知此答案。
5. T。本文主要讲述的就是卫星在天气预报领域中的使用情况。
B
6. B。根据文章第二段的“Neither could find a job, so the two decided to team up. 单独一个人谁都不能找到工作，结果是后面的他们组成了一个团队。从而推理出本题的答案B。
7. A。 根据文章第三段的 “In addition, it saves the village from river flooding during the rainy season.”可知A选项正确。
8. B。根据文章第四段中的 “Since they cannot afford to buy young trees to plant, the two use branches from existing trees. 可知他们种植树枝的原因是他们不花钱，答案为B。
