题目内容

Modern man has cleared the forests for farmland and for wood, and has also carelessly burned them. More than that, though, he has also interfered （干涉） with the invisible bonds between the living things in the forests. There are many examples of this kind of destruction. The harmfulness of man’s interference can be seen in what happened many years ago in the forest of the Kaibab plateau （凯亚巴布高原） of northern Arizona. Man tried to improve on the natural web of forest life and destroyed it instead.
The Kaibab had a storybook forest of large sized pine, Douglas fir, white fir, blue and Engelmann spruce. In 1882 a visitor noted, "We, who ... have wandered through its forests and parks, have come to regard it as the most enchanting region it has ever been our privilege （特权） to visit.”This was also the living place of the Rocky Mountain mule deer. Indians hunted there every autumn to gather meat and skins. The forest also had mountain lions, timber wolves and bobcats that kept the deer from multiplying too rapidly.
Then, in 1906, President Theodore Roosevelt made the Kaibab a national game preserve. Deer hunting was forbidden. Government hunters started killing off the deer’s enemies. In 25 years’ time, 6,250 mountain lions, wolves and bobcats were killed. Before the program, there were about 4,000 deer in the Kaibab, by 1924, there were about 100,000.
The deer ate every leaf and twig they could reach. But there was not nearly enough food. Hunting of deer was permitted again. This caused a slight decrease in the deer herd （鹿群），but a far greater loss resulted from starvation （饥饿） and disease. Some 60 percent of the deer herd died in two winters. By 1930 the herd had dropped to 20,000 animals. By 1942 it was down to 8,000.
【小题1】The destruction of the environment of the Kaibab resulted from .

A．turning the forest into cultivated land

There was great excitement on the planet of Venus(金星) this week. For the first time Venusian scientists managed to land a satellite on the planet Earth, and it has been sending back signals as well as photographs ever since.

The satellite was directed into an area known as Manhattan (named after the great Venusian astronomer Prof. Manhattan, who first discovered it with his telescope 20000 light years ago).

Because of excellent weather conditions and extremely strong signals, Venusian scientists were able to get valuable information as to feasibility (可行性) of a manned flying saucer (碟) landing on Earth. A press conference was held at the Venus Institute of Technology.

“We have come to the conclusion, based on last week’s satellite landing,” Prof. Zog said, “that there is no life on Earth.”

“How do you know this?” the science reporter of the Venus Evening Star asked.

“For one thing, Earth’s surface in the area of Manhattan is made up of solid concrete and nothing can grow there. For another, the atmosphere is filled with carbon monoxide (一氧化碳) and other deadly gases and nobody could possibly breathe this air and survive.”

“What does this mean as far as our flying saucer program is concerned?”

“We shall have to take our own oxygen with us, which means a much heavier flying saucer than originally planned.”

“Are there any other dangers that you discovered in your studies?”

“Take a look at this photo. You see this dark black cloud hovering(盘旋) over the surface of Earth? We don’t know what it is made of, but it could give us a lot of trouble and we shall have further tests before we send a Venus Being there.”

“Over here you will notice what seems to be a river, but the satellite findings indicates it is polluted and the water is unfit to drink. This means we shall have to carry our own water, which will add even greater weight to the saucer.”

“If all you say is true, won’t this set back the flying saucer program several years?”

“Yes, but we shall continue as soon as the Grubstart gives us the added funds.” Prof. Zog replied.

During the week of great excitement the Venusian scientists succeeded in getting important information as to ____.

A. the feasibility of landing a satellite on Earth

B. the possibility of making a first-rate flying saucer

C. the feasibility of sending a Venus Being to Earth

D. the possibility of directing a flying saucer into Manhattan

According to Prof. Zog, the Venusians will have to take their own oxygen with them when they carry out their flying saucer program because ____.

A. they need it in their way to the planet of Earth

B. the Earth’s atmosphere is filled with deadly gases

C. there is a low level of oxygen for Venusians

D. there is no air on the planet of Earth

The “dark black cloud” on the photo refers to ____.

A. the polluted air hovering over the surface of Earth

B. the mass of tiny drops of water floating above Earth

C. the mass of small things moving through the air

D. the dark clouds gathering before a storm breaks

The author wishes to call our attention to the fact that ____.

A. that modern man has polluted his environment to such an extend that he might destroy himself if he went on like this

B. that there is a point in spending billions to land a flying saucer on Earth

C. that pollution has become so serous a problem on Earth that even Venusians find life there unbearable.

D. that it is difficult if not altogether impossible, to land a manned flying saucer on Earth.

Through history, children have played with toys and they help to prepare children for adult life. But the toys are changing all the time. As science and technology have changed the way adults live, the toys children play with have changed as well. Developments in science and technology have had a big effect on the toys that children play with. Today trains and mobile phones are popular toys for young children, but there were no toys of this kind before real trains and mobile phones were invented. The materials that toys are made of have also changed. Today lots of toys are made of plastic. Plastic is a modern, man-made material that did not exist (存在) in the past. On the other hand, some other toys that you have might not be all that different from the ones children played with 1,000 years ago. Scientists have found some bone dice (骰子)in Aberdeen. In medieval (中世纪的)times dice were used for playing games as much as they are today.
A recent survey found that half of all the children aged from 4 to 6 have played video games, a quarter of them regularly. The increasing use of electronic toys troubles Dr Singer, a professor at Yale. “One thing we know is that kids in early years need to be in touch with the real world,” he said, “No matter how brilliant they are, they’re not going to learn to walk, to move or to talk to others unless their hands or feet have a direct role in such activities.”
Some toy experts argue that the best toys are the ones that increase a child’s creativity and imagination. Traditional toys can be used for different kinds of purposes and be used in group settings, individually(单独地), and one-to-one. They are also used differently depending on the child’s age and skill level. And these toys made of natural materials are valuable for children because they teach children what the world is made of.
【小题1】In how many ways do toys change according to the first paragraph?

【小题2】From the article, we can know that .

A．only children like to play with toys

B．toys have nothing to do with children’s future life

C．the development of toys is related to science and technology

D．plastic is the best material for making toys

【小题3】According to Dr Singer, .

A．the electronic toys are good for children if they play often enough

B．the electronic toys prevent children keeping in touch with the real world

C．children should be stopped from being hurt by the danger coming from the outside world

D．children should play with electronic toys instead of the traditional ones

C
1970 was World Conservation（自然保护）Year. The United Nations wanted everyone to know that the world is in danger. They hoped that people would act quickly in order to conserve nature（大自然）. Here is one example of the problem. At one time there were 1,300 different plants, trees and flowers in Holland, but now only 866 remain. The others have been destroyed by modern man. It is said that there are tens of thousands of kinds of animals in the world, but now many have died out（绝种）. We are changing the earth, the air and water, and everything that grows and lives . We can't live without these things. If we continue like this, we shall destroy ourselves.
What will happen in the future？Perhaps it is more important to ask“What must we do now？”The people who will be living in the world of tomorrow are the young of today. A lot of them know that conservation is necessary. Many are helping to save our world. They plant trees, build bridges across rivers and so on. In a small town in the United States a large group of girls cleaned the banks of 11 kilometres of their river. Young people may hear about conservation through a record called“No one's going to change our world.”It was made by the Beatles, Cliff Richard and other singers. The money from it will help to conserve wild animals.
