Task 2

Directions: This task is the same as Task 1. The 5 questions or unfinished statements are numbered 41 through 45.

The world is not only hungry; it is also thirsty for water. This may seem strange to you because 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 freshwater that comes from rivers, lakes, underground, and other sources. And we cannot use all of that, because some of it is in the form. of iceberg and glaciers (冰河). 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 day by day. 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.

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 a small scale. The systems that have been worked out resemble those used in spacecraft.

The first sentence "The world is not only hungry; it is also thirsty for water "means"______".

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 worldwide water shortage

D．people in the world all feel hungry and thirsty

第6题

If you live in a city in North America or Europe, you have probably never thought much abo

ut water. Whenever you need some, you turn on the tap and there it is. Millions of people in other parts of the world are not so lucky. They have trouble getting enough clean water for their basic needs. This situation may soon become common all around the world, scientists believe. In fact, they say that the lack of clean water may be one of the biggest issues in the twenty-first century.

The reasons for this are clear. On the one hand. people are using more water than ever before. Over the last fifty years, the population of the world has more than doubled. On the other hand, many sources of surface water such as rivers, lakes, and streams are too polluted and unhealthy for use as drinking water.

This has forced more and more people to drill wells so they can get water form. underground. There are enormous amounts of water deep underground in lakes called aquifers. Until recently, scientists believed this underground water was safe from pollution. Then, in the 1980s. people in the United States began to find chemicals in their well water, and scientists took a closer look at what was happening. Weldon Spring, Missouri, for example, was the site of a bomb factory during World War Ⅱ. The factory was destroyed after the war. but poisonous chemicals remained on the ground. Very slowly, these chemicals dripped down through the ground and into the aquifer. Once they did, however, the water form. that aquifer was no longer drinkable.

It probably never will be drinkable again, Underground water is not renewed regularly by the rain, like lake or river water. Thus, if a harmful chemical gets into an aquifer, it will stay there for a very long time. Furthermore, it is nearly imp6ssible to remove all the water in an aquifer and clean out the pollutants.

Industrial sites like Weldon Spring are one cause of underground water pollution. There are thousands of such sites in the United States alone, and many others around the world. Underground water pollution is also caused by modern farming methods, which require the use of large amounts of chemicals in the fields. And finally, yet another important cause of underground water pollution is waste. That includes solid waste thrown away in dumps and landfills, and also untreated human and animal waste.

The situation is indeed very serious. Fortunately, there are many aquifers and they are very large. Only a small number have been seriously damaged so far. But if the world does not want to go thirsty in the near future, further pollution must be prevented. Around the world, governments must make real changes in industry, agriculture, and waste disposal.

This passage is mainly about ______.

A．pollution problems in general

B．people in North America or Europe are living happier than those in other parts

C．people drilling wells to check chemicals in well water

D．underground water pollution

第9题

America is the land of the automobile. This country has only 6 percent of the world's popu

lation but 46 percent of the world's cars. Right now, there are 97 million privately owned cars consuming 75 billion gallons of gasoline and traveling an estimated 1,000 billion miles, a year. The figures also affirm something we know every time we refill our gasoline tank. The automobile is a very thirsty piece of technology. Of the total petroleum supply in the United States, 30 percent goes to quench that thirst. Every year for each passenger car, about 800 gallons of gasoline are consumed.

Other aspects of our commitment to the automobile also bear mentioning here, it takes a great deal of energy to manufacture one automobile—about 150 million BTUs of energy. This is equivalent to 1,200 gallons of gasoline, enough to run a car for about 16,000 miles. We expend energy in the process of shipping cars from factories to showrooms, displaying them for sale hand making replacement parts for repairs. One out of six jobs in the nation is associated with the automobile business. About two gallons of gasoline are consumed in the process of making every ten gallons that are pumped into an automobile's gas tank.

Building highways and parking lots has used up much of our land. It has been estimated that we have paved over 21,000 square miles of this country's surface, most of it to accommodate the automobile. The automobile is also the largest contributor to our nation's air pollution problem and a very serious one because most of its pollutants are emitted in our large metropolitan areas.

Aside from the great impact that would occur if everyone seriously practised conservation, one should stop and think about his own casual use of the automobile. There are numerous situations where better planning and awareness could really make a difference in energy savings and dollars. Because the automobile uses the largest percentage of energy in an average American family's energy budget and almost half of the dollars, the impetus for savings is tremendous.

According to the author, what do most people realize？______

A．Alternate sources of energy must be found

B．Car pools help to solve some of the energy problem

C．The automobile uses large amounts of gasoline

D．Great efforts have been made to solve the energy problem
