In the past, man did not have to think about the protection of his environment. There were few people on the earth, and natural resources seemed to be　46　.                    Today things are　 47　 , the world has become too　 48　 . We are using up our natural resources too quickly, and at the same time we are　 49　 our environment with dangerous chemicals. If we continue to do this, human life on the earth　 50　 survive.
　　Everyone　51　 today that if too many fish are taken from the sea, there will soon be none left. Yet, with modern fishing　 52 , more and more fish are caught. We know that if too many trees are cut down, 　53　 will disappear and nothing will grow on the land. Yet, we　 54　 to use bigger and more powerful machines to　55　 more and more trees.
　　We realize that if rivers are polluted with waste products from factories, we will die.　 56　 , in most countries wastes are　 57　put into rivers or into the sea, and there are　 58　 laws to stop this. We know, too, that if the　 59　of the world continues to rise at the present rate, in a few years there will not be enough 60　. What can we do to solve these problems ?
　  If  we eat more vegetables and less　 61　 , there will be more food available for everyone. Land that is used to grow crops　 62　 five times more people than land where animals are kept. Our natural resources will　 63　 longer if we learn to recycle them. The world population will not rise so quickly if people use modern methods of birth 64　 .
　　Finally, if we educate people to think about the problems, we shall have a better and clearer 65　in the future.

　　The world is not only hungry, it is also thirsty for water. This may seemstrange to you, since nearly 75％of the earth's surface is covered with water. But about 97％ of this huge amount is seawater, or salt water. Man can only drink and use the other 3％--the fresh water that comes from rivers, lakes, underground, and other sources. And we cannot even use all of that, because some of it is in the form of icebergs and glaciers. Even worse, some of it has been polluted.

　　However, as things stand today, this small amount of fresh water, which is constantly being replaced by rainfall is still enough for us. But our need for water is increasing rapidly almost everyday. Only if we take steps to deal with this problem now can we avoid a severe worldwide water shortage later on. A limited water supply would have a bad effect on agriculture and industry. Let me give you just one small example of how necessary water is to industry. Did you know that to produce a single ton of steel, it takes about 91000 litres of water?

　　We all have to learn how to stop wasting our precious water. One of the first steps we should take is to develop ways of reusing it. Experiments have already been done in this field, but only on small scale. The systems that have been worked out are similar to those used in spacecraft.

(1) “The world...is also thirsty for water.” this means that ________.

[　　]

A．the world has not enough fresh water to meet our future needs

B．people all over the world are thirsty for water now

C．we are now facing a serious problem of world-wide water shortage

[　　]

A．the small amount of fresh water is constantly being replaced by rainfall

B．some of it has been polluted

C．some of it is in the form of icebergs and glaciers

D．our need for fresh water is increasing rapidly

(4) According to the passage, one of the first problems is ________.

[　　]

A．to deal with water problem now

B．to have lectures on the water subject

C．to develop ways of reusing water

D．to work out systems that resemble those used in spacecraft

(5) This passage is mainly about ________.

　　The modern sailing ship was developed by a man who never went to sea. He was Prince Henry of Portugal, the younger son of the Portuguese King and an English Princess.

　　Prince Henry lived in the fifteenth century. As a boy he became devoted to the sea and he dedicated himself to improving the design of ships and the methods of sailing them. In 1416, when he was twenty-two, Henry founded a school for mariners, to which he invited everyone who could help him-Jewish astronomers, Halian and Spanish sailor, and Arab mathematicians and mapmakers who knew how to use the crude compass of the day and could improve it.

　　Henry's goal was to design and equip vessels that would be capable of making long ocean voyage without having to keep close to the shore. The caravel, which he helped design, carried more sails and was longer and slimmer than any ship was made, yet was tough enough to stand up against gales at sea. He also developed the carrack, which was a slower ship, but one that was capable of carrying more goods.

　　The world owes credit to Henry for the development of craft (工艺) that made oceanic exploration possible. He lives in history as Henry the navigator.

1．Prince Henry started his school for the purpose of ________.

[　　]

A．helping mariners

B．improving ship design and sailing methods

C．studying astronomy and mathematics

D．improving his own skill as a sailor

2．Prince Henry's goal was to design vessels that could ________.

[　　]

A．make long deep sea voyage

B．travel faster than those in use at that time

C．explore the coastline of Portugal

D．carry larger crews and more goods

3．Compared with his caravel, Henry's carrack was ________.

[　　]

A．longer and slimmer

B．able to carry more sails

C．able to carry more goods

D．shorter

4．Prince Henry's main achievement was that of ________.

[　　]

A．making oceanic exploration possible

B．improving the compass

C．founding a school for mariners

D．inventing caravel and carrack

5．The best title for this selection is ________.

[　　]

A．The First Modern Sailing Vessels

B．The Mariner Prince

C．Prince Henry's Role in the History of Ship-building

D．The First School for Sailors

　　The World Trade Organization（WTO）, established on January 1, 1995, is an open, non-discriminatory trading system. As a successor to the GATT, established in the wake of the Second World War, it is to help world's trade flow freely, fairly and predictably.

　　While the WTO is still young, the multilateral（多边的）trading system that was originally set up under GATT is already 50 years old. The system celebrated its golden jubilee（50周年纪念）in Geneva on 19 May, 1998, with many heads of states and government leaders attending.

　　The past 50 years have seen an exceptional（罕见的）growth in the world trade. Merchandise exports grew on average by 6％ annually（每年地）. Total trade in the WTO has helped to create a strong and prosperous trading system contributing to unprecedented growth.

　　China was an original member of GATT, but for historical and political reasons it was withdrawn from GATT by the government in Taibei in 1950. But over the last several years, China hopes to be seeking to resume（恢复）its contracting party status. China has become a member of the WTO before the body starts a new round of negotiations（谈判）late this year. Premier Zhu Rongji paid a nineday US visit from April 6, 1999. He is the first Chinese Premier to visit US. President Clinton agreed to have talks on China's entry into the WTO with a new round of negotiations in Beijing.

　　Now China has joined the WTO. China's entry into the WTO is not only of economical but also of political importance. China has made attracting progress since its reform and opening up to the outside world. It is growing more and more powerful in economy. China cannot be without the world just as the world cannot be without China. The entry of China into WTO will further strengthen the comprehensive national power of China; it can also quicken the economic development of the world.

According to the context, the underlined word in the first paragraph can be replaced by ______.

　　　　A. ordinary　　　　B. fair　　　　　 C. special　　　　　D. safety

GATT was founded in ______.

　　　　A. 1948　　　　　B. 1950　　　　　C. 1995　　　　　 D. 1998

　According to the passage and picture when did Shi Guangsheng, Minister of Chinese foreign economy and trade, signed the papers in Doha on China's accession to the WTO?

　A. 10,10,2001.　　 B. 11,11,2001.　　 C. 12,11,2001.　　 D. 11,10,2001.

Which of the following is the best title for the passage?

　　　　A. A General Introduction of WTO

　　　　B. How WTO Came into Being

　　　　C. GATT and WTO

　　　　D. WTO and China
