第4题
Men still did not know how to make a fire. When they had a fire they did not let it stop burning. If it went out, they could not start it again. They had to wait for lightning to start another fire! Sometimes they had to wait for years.
Later they discovered how to make a fire. If you rub pieces of wood together, they become hot and burn. You have to rub very fast! One way of doing it is to make a little hole in a piece of wood. Pieces of wood or dry leaves are put into the hole. Then you put the end of a stick into the hole. You rub the stick between your hands. This makes it turn very quickly. The end in the hole becomes very hot. The small pieces of wood and dry leaves begin to burn.
Another way of making a fire is to knock two stones together. This makes a spark. You can use this spark to start a fire. Nowadays we have matches. We can carry them in our pockets and make a fire when we want to. We also have cigarette lighters. They are, perhaps, handier and more useful than matches. There are, of course, other advanced methods of making a fire. Many people use heaters to keep warm. Oil heaters bum oil. Gas heaters burn gas. Electric heaters use electricity. We also use oil, gas and electricity for cooking.
How was fire first made？
A．Lightning hit a forest and started a fire.
B．People rubbed two pieces of wood together to make a fire.
C．People knock two pieces of stone together to make a fire.
D．People rubbed a stick between their hands to make a fire.

Passage Two
How men first learned to invent words is unknown. All we really know is that men, unlike animals, somehow invented certain sounds to express thoughts and feelings, actions and things, so that they could communicate with each other; and that later they agreed upon certain signs, called letters, which could be combined to represent those sounds, and which could be written down. Those sounds, whether spoken or written in letters, we call words.
The power of words, then, lies in their associations--the things they bring up before our minds. Words become filled with meaning for us by experience; and the longer we live, the more certain words recall to us the happy and sad events of our past; the more we read and learn, the larger the number of words that mean something to us becomes.
Great writers are those who not only have great thoughts but also express these thoughts in words which appeal powerfully to our minds and feelings. This attractive use of words is what we call literary style. Above all, the real poet is a master of words. He can express his meaning in words which sing like music, and, by their position and association, can move men to tears. We should therefore learn to choose our words carefully and use them correctly, or they will make our speech dull and silly.
Which of the following did men invent first？
A．Words.
B．Sounds.
C．Signs.
D．Letters.

Effects of Exercise on Elderly Diabetics (糖尿病人)
Most older people with. so-called type 2 diabetes (糖尿病) could stop taking insulin (胰岛素) if they would do brisk (轻快的) exercise for 30 minutes just three times a week, according to new medical research results reported in a Copenhagen newspaper. Results from tests conducted on diabetics at the Copenhagen central hospital Rigshospitalet's Center for Muscle Research showed that physical exercise can boost the body's ability to make use of insulin by 30 per cent. This is equal to the effect most elderly diabetics get from their insulin medication (药物治疗) today.
Researchers had a group of non-diabetic men and a group of men with type 2 diabetes, all more than 60 years of age, exercise on bicycles six times a week for three months. After the three months the doctors measured how much sugar the test subjects' muscles could make use of as a measure for how well their insulin worked.
Associate Professor Dr Flemming Dela of the Muscle Research Center said the tests demonstrated that the exercising diabetics had made as good use of insulin as the healthy non-diabetic persons. "This means that the insulin works just as well for both groups. Physical exercise cannot cure people of diabetes, but it can eliminate almost all their symptoms. At the same time it can put off the point at which they have to begin taking insulin," Dela said.
Insulin is a hormone produced by the pancreas (胰腺), controlling sugar in the body and is used against diabetes.
Dela said that to achieve the desired effect diabetics need only exercise to the point where they begin to sweat, but that the activity has to be maintained since it wears off after five days without sufficient exercise.
Most diabetics realize that they have to watch their diet while remaining unaware of the importance of exercise, Dela added.
What is the effect of exercise on elderly people with type 2 diabetes？
A．It can help the body make better use of insulin.
B．It can worsen their symptoms.
C．It can help them to eat more.
D．It can cure them of the disease.

第10题
听力原文： What will man be like in the future--in 5,000 or even 50,000 years from now.'？ We can only make a guess, of course, but we can be sure that he will be different from what he is today. For man is slowly changing all the time. Let us take an obvious example. Man, even five hundred years ago, was shorter than he is today. Now, on average, men are about three inches taller. Five hundred years is a relatively short period of time, so we may assume that man will continue to grow taller. Again, in the modern world we use our brains a great deal. Even so, we still make use of only about 20% of the brain's capacity. As time goes on, however, we shall have to use our brains more and more--and eventually we shall need larger ones! This is likely to bring about a physical change too: the head, in particular the forehead, will grow larger. Nowadays our eyes are in constant use. In fact, we use them so much that very often they become weaker and we have to wear glasses. But over a very long period of time it is likely that man's eyes will grow stronger. On the other hand, we tend to make less use of our arms and legs. These, as a result, are likely to grow weaker. At the same time, however, our fingers will grow more sensitive because they are used a great deal in modem life.
(30)
A．Future man's life style.
B．Future man's thoughts.
C．Future man's appearance.
D．Future man's education.
