Read the following article and select the best answer. Article: The black robin is one of the world's rarest birds. It is a small, wild bird, and it lives only on the island of Little Mangere, off the coast of New Zealand. In 1967 there were about fifty black robins; in 1977 there were fewer than ten. These are the only black robins left in the world. The island has many other birds, of different kinds, large and small; these seem to multiply very happily. Energetic steps are being taken to preserve the black robin. Detailed studies are going on, and a public appeal for money has been made. The idea is to buy another island nearby as a special home, a "reserve", for threatened wild life, including black robins. The organizers say that Little Mangere should then be supplied with the robin's food--it eats only one kind of seed. Thousands of the required plants are at present being cultivated in New Zealand. The public appeal is aimed at the conscience of mankind, so that the wild black robin will not die out and disappear form the earth in our time at least. Is all this concern a waste of human effort? Is it any business of ours whether the black robin survives or dies out? Are we losing our sense of what is reasonable and what is unreasonable? In the earth's long, long past, hundreds of kinds of creatures have evolved, risen to a degree of success--and died out. In the long, long future, there will be many new and different forms of life. Those creatures that adapt themselves successfully to what the earth offers will survive for a long time. Those that fail to meet the challenges will disappear early. This is nature's proven method of operation. The rule of selection--"the survival of the fittest"--is the one by which human beings have themselves arrived on the scene. We, being one of the most adaptable creatures the earth has yet produced, may last longer than most. You may take it as another rule that when, at last, human beings show signs of dying out, no other creature will extend a paw to put off our departure. On the contrary, we will be hurried out. For nature,... Question: The black robin is dying out mainly because _ . - people have been very careless about its survival - the appeal for money has come at the wrong time - the other birds on the island have destroyed it - its only food supply is far from enough on Little Mangere
its only food supply is far from enough on Little Mangere

Read the following article and select the best answer. Article: Two American scientists told the people in industrial nations that they would be much healthier if they ate more of the same kind of foods eaten by humans living more than 10,000 years ago. The scientists say that the human body has changed very little since human first appeared on earth, but the way we live has changed greatly. Our body has not been able to deal with these changes in life style and this has led to new kinds of sicknesses. These new sicknesses were not known in ancient times. So they are called "diseases of civilization". Many cancers and diseases of the blood system, including heart attacks and strokes are examples of such diseases. Scientists noted that early stone-age people used very little alcohol or tobacco, probably none. Ancient people also got a great deal of physical exercise, but a change in food is one of the main differences between life in ancient times and life today. Stone-age people hunted wild animals for their meat, which had much less fat than farm animals. They also ate a lot of fresh wild vegetables, and fruits. They did not use milk and other dairy products, and they made very little use of grains. But today, we eat a large amount of dairy products and grain foods. We eat six times more salt than stone-age people. We eat more sugar. We eat twice as much fat but only one third as much protein and much less vitamin C. People today probably do not want to live as people thousands of years ago did, but scientists say that we would be much healthier if we ate as those ancient people did, cutting the amount of fatty, salty and sweet foods. Question: The people in industrial nations would be much healthier if they ate _ . - more foods as humans living 10,000 years ago did - as humans living 10,000 years ago ate - more kinds of food eaten by people living over 10,000 years ago - more of the same kinds of foods eaten by people over 10,000 years ago
more of the same kinds of foods eaten by people over 10,000 years ago

Read the following article and select the best answer. Article: It was about six years ago.We were at senior high school.Those days in school were gray to most Chinese students because of the college entrance examination pressure.Not our parents and teachers didn't love us,but they loved us too much.Our only happiness was a high grade in the exam. One afternoon after the final exam,we four girls came to a small wood and we felt _ only belonging to us that afternoon.We talked and laughed.We played all the games that we could think of.We felt we were on the top of the world for the first time in our life.We totally forgot the unhappiness in our life and we threw the homework and the endless exams far away out of the wood. In the middle of the wood ran a small and peaceful stream.Now and then,we could see some wild ducks on the water looking for food.The water weeds danced happily while the water passed beside them.The air was so fresh that we breathed it freely. The sun had set before we knew it.We had to leave the place which brought us much happiness.We agreed to come back again every time we felt bored. Years later,we went there several times.But,every time we went there to find that great feeling,we failed.Strangely,the feeling was different from that of several years ago. I know that wonderful experience was just for once.We can never find that kind of happiness again which only belonged to the special afternoon in our life.That was a release of our uneasy heart.We can never go back to that young age or that simple life.It was our golden ages.No matter how boring and hard the life was,it gave us something worthy to recall.We'll treasure it forever. Question: What does the writer think of their senior high school life? - Unhappy. - Helpless. - Useless. - Meaningless.
Unhappy.
