题目列表(包括答案和解析)
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.
There is much pollution in the air today because ___________.
A. people drive big cars
B. people drive little cars
C. the cars go 65 kilometers an hour
D. the cars can go 450 kilometers an hour

A. much smaller than B . much the same as
C. three times as large as D. a little larger than
Which of the following is NOT true?

Big cars are not useful for long trips
The cars of the future will be smaller than today’s cars.

The street will be less crowded because ______________.
A there will be fewer cars in the future
B. driving future cars will be safer
C. there will be fewer passengers in the street
D. future cars will be much smaller

there will be too many cars in the future
more and more people will get around a city
bit cars and little cars may be used along with each other

A thousand years ago Hong Kong was covered by a thick forest like the forests we now find in Malaysia and Thailand. As more and more ___36___ came to live in Hong Kong, these trees were cut down and burnt. Now there is no forest left, ___37__ there are still some areas covered with trees. We call these __38__.
Elephants, tigers, monkeys and many other animals used to live in the __39__ forests of Hong Kong, and there were even crocodiles in the ___40__ and along the coast. When people came to live in Hong Kong, the animals began to __41___ out. Early farmers grew rice and kept pigs and chickens in the valleys.
They ___42___ the trees and burnt them. They needed fires to keep themselves ___43___ in the winter, to cook their food, and to keep away from dangerous animals. Elephants quickly disappeared because there was not enough ___44___ for them. So did most of the wolves, and tigers. Monkeys, squirrels and many other animals soon died out in the same __45____.
You might think that there are ___46___ any animals in Hong Kong, except in the __47_____. You might think there can’t be any wild animals in such a __48___ place with so many cars and buildings. But there is __49_____ a good deal of countryside in Hong Kong and New Territories, and there are still about thirty-six different kinds of animals living there.
One of the most interesting of Hong Kong’s ____50___ is the barking deer. They are beautiful little creatures with rich, brown coat and a white patch under the tail. They look like deer but they are much ___51___. They are less than two feet high. The male barking deer has two small horns but the female has none. They make a __52____ rather like a dog barking.
Barking deer live in thick shrub(灌木) country and are very good at __53___. They eat grass and shrubs, mainly in the very early morning and late afternoon and evening. This is when you are most likely to see one but you will need to be very quiet and to have very ___54___eyes. In Hong Kong the barking deer has only one ___55_____ ---- man. Although it is illegal, people hunt and trap these harmless little animals. As a result there are now not many left. There are a few on Hong Kong Island but none in the New Territories.

Flying over a desert 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 notebook, "Look here for probable metal." 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 powers 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 signs that certain minerals may lie under 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 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 less 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 trees indicated that there was no gold in the ground, the scientists wouldn’t spare money to pay for digging into the ground.
