can cause problems. For example, too many tourists can crowd public places that are also enjoyed by the inhabitants(居民) of a country. If tourists create too much traffic, the inhabitants become angry and unhappy. They begin to dislike tourists and to treat them impolitely. They forget how much tourism can help the country’s economy. It is important to think about the people of a destination(目的地) country and how tourism affects them. Tourism should help a country keep the customs and beauty that attract tourists. Tourism should also advance health and happiness of local inhabitants.

Too much tourism can be a problem. If tourism grows too quickly, people must leave other jobs to work in the tourism industry. This means that other parts of the country’s economy can suffer.

On the other hand, if there is not enough tourism, people can lose jobs. Businesses can also lose money. It costs a great deal of money to build large hotels, airports, first-class roads, and other support facilities(设施) needed by tourist attractions. For example, a major international-class tourist hotel can cost as much as 50 thousand dollars per room to build. If this room is not used most of the time, the owners of the hotel lose money.

Building a hotel is just a beginning. There must be many support facilities as well, including roads to get to the hotel, electricity, sewers(阴沟) to handle waste, and water. All of these support facilities cost money. If they are not used because there are not enough tourists, jobs and money are lost.

60. Which of the following has most probably been discussed in the paragraph that goes before the passage?

A. It is not important to develop tourism.

B. Building roads and hotels is important.

C. Support facilities are highly necessary.

D. Planning is of great importance to tourism.

61. Too much tourism can cause all these problems except _____.

A. a bad effect on other industries

B. a change of the customs of the country

C. air and water pollution

D. pressure on traffic

62. Not enough tourism can lead to _____.

A. the fact that some people may be out of work

B. an increase in tourist attractions

C. the higher cost of support facilities

D. a rise in price and a fall in pay

63. The word“handle”in the last paragraph most probably means _____.

A. carry away B. pick up C. get in D. take down

C

It is only during the last few years that man has generally realized that in the world of nature a balance exists between all forms of life. No living thing can exist by itself. It is part of a system in which all forms of life are joined together. If we change one part of the nature order, this will almost certa inly bring about changes in some other part.

The cutting of forests reduced the supply of oxygen. The killing of weeds and insects by chemicals led to the wide-spread poisoning of animals and birds. The throwing of waste products into the ocean hurt life in the sea, while waste gases changed the chemical balance of the atmosphere and shut out some of the sun’s necessary life-giving rays.

And so we could go on adding more examples until in despair(绝望) we might feel like giving up the struggle to control these harmful human activities. Man is very clever at changing the world around him to satisfy his immediate needs, but he is not so clever at looking far ahead, or at thinking about what the future results of his action might be. Man may well destroy himself because of his silly action.

64. The first paragraph tells us that _____.

A. all living things in nature depend on each other

B. everything in nature can’t exist without the help of man

C. man has known the importance of the balance of nature for a long time

D. no living thing can live naturally

65. In the second paragraph the examples given are used to prove that _____.

A. all forms of life belong to a system in which all the parts can be changed for one another

B. it is only during the last few years that man has generally known the balance of nature

C. there are some living things which can exist by themselves without change

D. we can’t change one form of life without destroying the balance of nature

66. The last paragraph suggests that in order to get his immediate benefits(利益) _____.

A. man is always anxious to control his activities within limits

B. man is always too eager in planning for distant future

C. man often fails to think about their future results of his action

D. man often feels that he will have to give up in despair

67. Which of the following is true according to the passage?

A. Cutting down woods does little harm to human beings.

B. Man has to pay much more attention to the future results of his present action.

C. Oxygen comes from forests.

D. The passage tells us to try our best to get as much as possible immediately.

D

Scientists used to explore on the surface of the ocean. Now they are exploring below the surface, too. They want to know about ocean water and the plant and animal life deep in the ocean.

In 1934 the scientist William Beebe dived 3,000 feet below the surface in a hollow steel ball. In 1935 August Piccard dived 10, 330 feet. In 1960 his son Jean dived to a depth of 35,800 feet.

All these early dives were deep. But the divers could not stay down for very long. They had to come back up to the surface after a few seconds. Scientists needed to stay down longer to study life below the surface. Gradually they succeeded. Cousteau, a Frenchman, was able to keep men down to a depth of 36 feet for one month and to a depth of 90 feet for a week.

Now scientists are developing even better equipment. With this new equipment, men can stay below the surface for days or even weeks. In 1962 Cousteau set up a research station 35 feet below the surface. Then in 1964 he set up another station on the ocean floor of the Red Sea. This was the first undersea station to operate without help from the surface.

Many countries are now studying undersea living things. The former Soviet Union had an undersea laboratory in the Crimean Sea. The United States has a laboratory 50 feet down on the ocean floor off the Virgin Islands. In 1970 five men lived there for two weeks. Then a team of five women scientists stayed in the laboratory. Next came other teams of men. All were there to explore the ocean depths and to make plans for the use of its resources. Scientists hope to find enough mineral, vegetable, and animal wealth there to provide food for the entire world.

68. In order to _____, scientists are exploring below the surface of the ocean.

A. know about the ocean water deep in the ocean

B. know about the plant and animal life deep in the ocean

C. stay down longer to study life of the plant and animal below the surface

D. both A and B

69. Who made the deepest dive?

A. August Piccard B. Cousteau C. Jean Piccard D. William Beebe

70. Who set up the first undersea station?

A. A Frenchman B. An American C. A Russian D. The passage made no mention

71. Which of the following is true according to the passage?

A. Nobody can stay below the surface of the ocean.

B. The early divers could not stay below the surface of the ocean for very long.

C. The purpose of setting up the undersea laboratories is to make plans for the use of the resources in the ocean.

D. Up to now only five women scientists have stayed in the undersea laboratory.

I gave my housekeeper an old pair of trousers to wash and went into the reading room to read. My housekeeper usually examined my pockets before she washed anything, but for some reason she failed to do so this time. As I was reading I suddenly remembered that there was a ten-pound note in the back pocket of the t rousers I had given her to wash. I dropped my book right away
