A kind of little cars may some day take the place of today’s ones. If everyone drives such cars in the future, there will be less pollution in the air. There will also be more space for parking cars in cities, and the streets will be less crowded. Three such cars can fit in the space now needed for one car of the usual size.

The little cars will cost much less to own and to drive. Driving will be safer, too, as these little cars can go only 65 kilometers an hour.

The cars of the future will be fine for getting around the city, but they will not be useful for long trips. Little cars will go 450 kilometers before needing to stop for more gasoline.

If big cars are still used along with the small ones, two sets of roads will be needed in the future. Some roads will be used for the gig, fast cars and other roads will be needed for the slower small ones.

Within a few short years, girls in Europe have become heavier smokers than boys, for reasons experts still fail to understand, according to a British study, presented(递交) last week to an international conference on smoking.   

Anti-smoking activists at the second “Tobacco or Health” conference in the Canary Islands pointed out that while grown-ups were giving up smoking in ever-growing numbers, more and more young people were taking up the habit, particularly girls.   

One 15―year―old in four is a regular smoker, according to a study made in 27 countries in Europe and the United States, Canada and Israel――Edinburgh University together with the World Health Organization.   

In Western Europe, girls were more likely than boys to smoke. In Germany or In England, one third of the girls were smokers compared to one in four boys. In Eastern Europe, the girls “still fall behind” those in the Western Europe but were “catching up” quickly, said the study.   

The study dealt with the behaviour of 15―year―old in seven European countries over four year periods between 1986 and 1998.   

The percentages of young women smoking went from 17 percent to 36 percent in Austria, from 17 percent to 28 percent in Norway, from 21 percent to 28 percent in Hungary.   

In the seven countries Austria, Finland, Hungary, Norway, Sweden, Switzerland and Wales―more girls smoked than boys in 1998, except Hungary.   

41．According to the article, more and more           in Europe were giving up smoking.   

A．grown-ups                 B．boys                   C．girls                    D．old men 

42．The number of boy smokers is           that of girl smokers.   

A．larger than                  B．as large as           C．smaller than         D．as small as 

43．The study was made by            .   

A．Edinburgh University 

B．the World Health Organization 

C．Oxford University

D．Edinburgh University and the World Health Organization

44．The country where the number of young women smokers increases fastest is           .  

A．Norway                     B．Austria                C．Hungary              D．Sweden

Flying over a desert area in an airplane, two scientists looked down with trained eyes at trees and bushes．After an hour’s flight one of the scientists wrote in his book, “Look here for probable mental．” Scientists in another airplane, flying over a mountain region, sent a message to other scientists on the ground, “ Gold possible”．Walking across hilly ground, four scientists reported, “This ground should be searched for metals．” From an airplane over a hilly wasteland a scientist sent back by radio one word, “Uranium”

None of the scientists had X-ray eyes; they had no magic power for looking down below the earth’s surface．They were merely putting to use one of the newest methods of locating minerals in the ground—using trees and plants as sighs that certain minerals may lie beneath the ground on which the trees and plants are growing．

This newest method of searching for minerals is based on the fact that minerals deep in the earth may affect the kind of bushes and trees that grow on the surface．

At Watson Bar Creek, a brook six thousand feet high in the mountains of British 39, however, one tends to believe fully in the reality of the dream world, Columbia, Canada, a mineral search group gathered bags of tree seeds．Boxes were filled with small branches from the trees．Roots were dug and put into boxes．Each bag and box was carefully marked．In a scientific laboratory the parts of the forest trees were burned to ashes and tested．Each small part was examined to learn whether there were minerals in it．

Study of the roots, branches, and seeds showed no silver．But there were small amounts of gold in the roots and a little gold in the branches and seeds．The seeds growing nearest to the tree trunk had more gold than those growing on the ends of the branches．

If the tree had not indicated that there was gold in the ground, the scientists would not have spent money to pay for digging into the ground．They did dig and found more gold below．They dug deeper．They found large quantities of gold．

1．Scientists were flying over a desert or a hilly wasteland or a mountain region in order to search for __________．

A．gold　　　　 　　 B．silver　　　 　　 C．metals　　　　 　 D．minerals

2．The study of trees, branches and roots indicates that ________

A．there were larger amounts of gold in the branches than in the seeds

B．there were smaller amounts of gold in the roots than in the branches

C．there were larger amounts of gold in the seeds growing nearest to the tree trunk than seeds growing on the ends of branches

D．there were more gold in the branches than in the roots

3．Which is the best title suggested below?

A．Scientists Searching for Metals with Special Power

B．New Methods of Searching for Minerals

C．Gold Could Be Found by Trees and Plants

D．A New Method of Searching for Minerals –Using Trees and Plants

4．Which of the following is NOT mentioned as part of a tree that can help find minerals?

A．Leaves　　　 B．Roots　　　 　 C．Branches　　　　 D．Seeds

5．The scientists were searching for minerals by using ________．

A．X-ray　　　　 　　　 　　　　　 B．Magic power 　　

C．a special instrument　　 　　　　　　　 D．trained eyes
