摘要：( ) Which is the best title for this passage? A. The History of the Internet B. Computers and Information C. Computers and the Government D. The History of Computers Passage 2 Nearly all our food comes from the soil. Some of us eat meat, of course, but animals live on plants. If there were no plants, we would have no animals and no meat. So the soil is very necessary for life. The top of the ground is usually covered with grass or other plants. There may be dead leaves and dead plants on the grass. The waste matter (粪) from animals also falls on it. All soil needs food. If we do not give it any, the plants will be weak. Farmers found that animals’ waste is the best food for the soil, but chemical fertilizers are also very useful. The same crop should not be grown in the same place every year; it’s better to have a different crop. A change of crop and the use of a good fertilizer will keep the land good.

　　A Chinese man called Cai Lun invented paper almost 2,000 years ago．He made it from wood．He took the wood from trees and made it into paper．He then put these pieces of paper together and made them into a book．

　　Now paper still comes from trees．We use a lot of paper every day．If we keep on wasting so much paper, there will not be any trees left on the earth．If there are no trees, there will be no paper．Every day, people throw away about 2,800 tons of paper in our city．It takes 17 trees to make one ton of paper．This means that we are cutting nearly 48,000 trees every day．Since it takes more than 10 years for a tree to grow, we must start using less paper now．If we don’t, we will not have enough time to grow more trees to take the place of those we use for paper．

　　So how can we save paper? We can use both sides of every piece of paper, especially when we are making notes．We can also use cotton handkerchiefs(手帕)and paper ones．When we go shopping, we can use fewer paper bags．If the shop assistant does give us a paper bag, we can save it and refuse(拒绝)it later．

　　Everyone can help to save paper．If we all think carefully, we can help protect trees．But we should do it now, before it is too late．

　　In the 13th century（世纪）,the famous Italian traveller, Marco Polo, travelled a long way to China. During he stay in China, he saw many wonderful things. One of the things he discovered was that the Chinese used paper money. In western countries, people did not use paper money until the 15th century. However, people in China began to use paper money in the 7th century.

　　A Chinese man called Cai Lun invented paper almost 2 000 years ago. He made it from wood. He took the wood from trees and made it into paper. He then put these pieces of paper together and made them into a book.

　　Now paper still comes from trees. We use a lot of paper every day. If we keep on wasting so much paper, there will not be any trees left on the earth. If there are no trees, there will be no paper. Every day, people throw away about 2 800 tons（吨）of paper in our city. It takes 17 trees to make one ton of paper. This means that we are cutting nearly 48 000 trees every day. Since it takes more than 10 years a tree to grow, we must start using less paper now. If we don't, we will not have enough time to grow more trees to take the place of those we use for paper.

　　So how can we save paper? We can use both sides of every piece of paper, especially when we are making notes. We can choose drinks in bottles instead of those in paper packets. We can also use cotton handkerchiefs（手帕）and not paper ones. When we go shopping, we can use fewer paper bags. If the shop assistant does give us a paper bag, we can save it and reuse it later.

　　Everyone can help to save paper. If we all think carefully, we can help protect trees. But we should do it now, before it is too late.

Two Chinese spacecrafts successfully completed China’s first space docking early November 3, 2011, which has taken the country a step closer to building its own space station.
Nearly two days after its launch, the unmanned spacecraft Shenzhou VIII docked with the space lab module Tiangong I more than 343 km above the earth surface. Shenzhou VIII and Tiangong I took apart after flying together for 12 days. On the 14th of November, the two spacecrafts finished the second docking. Then Shenzhou VIII parted from Tiangong I again and returned to the earth safely on the 17th. Tiangong I is still traveling around the earth in the space, waiting for the arrival of Shenzhou IX and X and so on in the near future.
That marked another great leap for China’s space program and made China the third country in the world, after the United States and Russia, to master the space docking technique (空间对接技术).
The world’s first space docking was achieved in 1966, when the manned U.S, spacecraft Gemini 8 (双子星8号) docked with an unmanned Agena Target Vehicle (阿金纳目标飞行器). Space docking is necessary to explore space beyond Earth’s orbit. “The capability increases China’s ability to act independently in space, as well as its ability to work together with others,” said Gregory Kulacki, a U.S. space scientist and senior analyst.
“With the success of its first space docking, China is now equipped with the basic technology and ability required for the construction of a space station,” said Zhou Jianping, chief designer of China’s manned space program.” The country is on its way to building a permanent manned space station around 2020.”
小题1:What did the success of the first space docking mean to China?

A．China has caught up with the United States in the space exploration field.

B．China took a step closer to building its own space station.

C．China became the first country to master the space docking technique.

D．China has the ability to build a permanent manned space station right now.

小题2:What does the underlined word “That” in the third paragraph refer to?

A．Shenzhou VIII.

B．Tiangong I

C．The Space Station

D．The success of China’s first space docking

小题3:What can we learn from the passage?

A．Tiangong I will fly in the space for 12 days.

B．The first space docking of the world was achieved in 1966, by Russians.

C．Without space docking technique people can’t explore space beyond Earth’s orbit.

D．The U.S.A helped China achieve the first space docking.

小题4:What’s the best title of this passage?

A．The first space docking of China.

B．The history of space docking.

C．The first space docking of the world.

D．The space docking technique

仔细阅读下列短文, 根据题目, 选出最佳选项. Rivers are one of our most important natural resources(自然资源). Many of the world's great cities are located on rivers, and almost every country has at least one fiver flowing through it that plays an important part in the lives of its people. Since the beginning of history, people have used rivers for transportation. he longest one in the United States is the Mississippi. The lifeline of Egypt is Nile. To the people of India, the Ganges is great, but it is also important for transportation; ships can travel along it for a thousand miles. Other great rivers are the Congo in Africa and the Mekong in Southeast Asia. The greatest of all for navigation(航海), however, is the Amazon in Brazil(巴西). It is so wide and so deep that large ships can go about two thousand miles upon it. Besides transportation, rivers give food to eat, water to drink, water for crops, and chances for fun and recreation for the people who live along their banks. In order to increase the supply of water for crops, engineers sometimes build a dam(大坝) across a river and let a lake form behind the dam. Then people can use the water not only to irrigate(灌溉) their fields but also to make electricity for their homes and industries. However, large cities and industries that are located upon rivers often make problems. As the cities grow in size and industries increase in number, the water in the rivers becomes polluted with chemicals and other materials. People are learning the importance, however, of doing more to keep their rivers clean if they want to enjoy the benefits(利益) of this natural resource.

(1)

The greatest river for navigation is ______.

A. the Amazon

B. the Nile

C. the Mekong

D. the Mississippi

[　　]

(2)

Which of the following is WRONG according to the passage

A. The Nile is in India.

B. Almost every country has at least one important river.

C. Many cities are located on rivers.
