Passage 1
Questions1-15 are based on the following passage.
It's interesting that the arrival of snow has the effect on people in different countries.(76) For some countries it is an important happening to celebrate each year, while for others a catastrophe (灾害) or even a wonder.
But there are countries between these two kinds that normally expect snow some time over the winter months, but never receive snow regularly or in the same quantities every year. Britain is one of them, for which the arrival of snow quite simply creates problems. Within hours of the first snowfalls, however light, roads are blocked; trains and buses have to stop in the middle of the way. Normal communications are affected as well: telephone calls become difficult and the post immediately takes more time than usual. And almost within hours there are also certain shortages—bread, Vegetables and other things—not because all these things can no longer be produced or sent to shops,but mainly because people are frightened and go out and store up with food and so on...just for fear that something bad should happen.
But why does snow have this effect? After all, the Swiss, the Austrians and the Canadians don't have such problems. It is simply because there is not enough planning and preparation. We need money to buy equipment to deal with snow and ice. To keep the roads clear, for example, requires snow-ploughs (扫雪机) and machines to spread salt. (77) The reason why a country like Britain does not buy snow-ploughs is that they are only used for a few days in any one year, and the money could be more useful in other things such as hospitals, education, helping the old, and so on.

Passage 1
Questions6-20 are based on the following passage．
We find that bright children are rarely held back by mixed-ability teaching．On the contrary, both their knowledge and experience are enriched．We feel that there are many disadvantages in streaming (按智力划分）upils． It does not take into account the fact that children develop at different rates． It can have a bad effect on both the bright and the not-so-bright child． After all, it can be quite discouraging to be at the bottom of the top grade!
Besides, it is rather unreal to grade pupils just according to their intellectual ability． This is only one aspect of their total personality． (76) We are concerned to develop the abilities of all our pupils to the full,not just their academic ability． We also value personal qualities and social skills,and we find that mixed-ability teaching contributes to all these aspects of learning．
In our classrooms, we work in various ways． The pupils often work in groups: this gives them the opportunity to learn to cooperate, to share, and to develop leadership skills． They also learn how to cope with personal problems as well as learning how to think, to make decisions, to analyze and evaluate, and to communicate effectively． The pupils learn from each other as well as from the teacher．
Sometimes the pupils work in pairs; sometimes they work on individual tasks and assignments, and they can do this at their own speed． They also have some formal class teaching when this is appropriate． We encourage our pupils to use the library, and we teach them the skills they need in order to do this efficiently．An advanced pupil can do advanced work: it does not matter what age the child is． We expect our pupils to do their best, not their least, and we give them every encouragement to attain this goal．

11、Questions 11-25 are based on the following passage.
Salt is as necessary to life as water. In many areas of Africa people once drank the urine (尿）
of animals because they had no other source of salt. Without salt, human beings die.
The human body demands that the amount of salt in the blood always stay the same. When the body does not get enough salt, it protects itself by letting less salt leave the body in urine and sweat. But it carmot reduce this output to zero. Some salt is always escaping. On a complete saltless diet, like that of some people in Africa, the body steadily loses small amounts of salt through the kidneys (肾) and sweat glands (腺）It then tries to adjust to this loss by speeding its secretion (分泌) of water. (78) In this way, the body attempts to keep the amount of salt in the blood at the necessary level. The result is a slow drying up of body and,inally,death. The person dies of thirst.
In cases where there is little or no water to drink, the body tries to do the opposite thing. Again, it must keep the salt level in the blood constant. Because it has little water, it attempts to stop water from leaving the body and to increase its secretion of salt. But, as with the escaping salt, it cannot be completely successful. Some water still leaves and the person eventually dies of thirst. In short, the body's normal needs for salt and for water are both parts of the same important need to keep the salt level in the blood constant.

A．when they were going to die
