In only a short time, computers have【B8】changed the way in which many kinds of work are done.【B9】, they have created whole new areas of work that did not exist【B10】to their development. We have all heard of computers【B11】the course of rockets, preparing bank statements,【B12】elections, forecasting weather, and so【B13】Computers do many tasks for us that would be【B14】difficult if we did not have them. Computers take routine tasks and do them in a【B15】of the time it would take a man or even a【B16】of men to do them.
Many people imagine that a computer is a very large【B17】machine. Certainly a computer can function in that way,【B18】this is a very restricted view of the nature of a computer. The message of a familiar【B19】is that machines should work, but men should think. This is the basic philosophy of computer science,【B20】in the advanced states of computer technology.

Read the following article in which five people talk about the future. For Question 61 to 65, match the name of each speaker to one of the statements (A to G) given below. Mark your answers on ANSWER SHEET 1.
Paula:
The future is determined by the actions of the present day. The responsibility we have for the future begins when we recognize that we ourselves create the future—that the future is not something imposed upon us by fate or other forces beyond our control. We ourselves build the future both through what we do and what we do not do.
Mrs. John:
The future will see more unbelievable things. In the future, people will be able to predict their performance from the strength of the brain's electrical activity. Doctor Kramer has found that the strength of the brain's electrical activity can be measured through the scalp (头皮). Bosses could measure brain activity through the scalp and tell whether a worker is performing well, working hard, or too tired to do the job properly.
Mary:
In the new century, things around us will be more fascinating. The chemical element in the heart is said to increase your desire for fat, when is stimulated. This means that disturbances of this chemical gelatin can lead to overeating. Doctor Sarah Leibowits presented an academic paper suggesting that the appetite for fat rich food can be controlled through drugs that block the effects of gelatin.
Judy:
In the future our life will change dramatically. It is quite certain that computers will play an important part in our life. You will visit your doctor, and find that he uses a computer screen and visual information about your condition, instead of his text books. Computers in your home will enable you to answer interactive questions about your health and show the alternative results which will affect you if you act in a certain way.
Carrie:
In the future, computers will change the way the doctors diagnose and treat their patients. Also doctors will change their traditional notion of medicine. Although pills for tension, heart conditions, being overweight and other life threatening conditions are prescribed by western doctors, most doctors now require patients to focus on healthy way of living by changing diets and doing more exercise as a means to keep fit.
Now match each of the items (61 to 65) to the appropriate statement.
Note: there are two extra statements.
Statements
[A] You build your own future.
[B] Healthy lifestyle. will be a more popular way to keep fit.
[C] Computer will be an effective tool for doctors.
[D] Doctors may not need pills for heart troubles or overweight
[E] Your brain waves may be used to check out your work performance.
[F] People will be able to visit doctors more frequently.
[G] Our appetite will be well controlled by drugs.

第5题
All foods contain water--cabbage and other leaf vegetables contain as much as 93% water, potatoes and other root vegetables 80% , lean meat 75% and fish anything from 80% to 60% depending on how fatty it is. If this water is removed, the activity of the bacteria(细菌) which cause food to go bad is checked.
Nowadays most foods are dried mechanically. The conventional method of such dehydration(脱水) is to put food in chambers through which hoi air is blown at temperatures of about 110°C at entry to about 43°C at exit. This is the usual method for drying such things as vegetables, minced meat, and fish.
Liquids such as milk, coffee, tea, soups and eggs may be dried by pouring them over a heated horizontal steel cylinder or by spraying them into a chamber through which a current of hot air passes. In the first case, the dried material is scraped off the roller as a thin film which is then broken up into small, though still relatively coarse flakes. In the second process it falls to the bottom of the chamber as a fine powder.
Dried foods 'take up less room and weigh less than the same food packed in cans or frozen, and they do not need to be stored in special conditions. For these reasons they are invaluable to climbers, explorers and soldiers in battle, who have little storage space. They are also popular with housewives because it takes so little time to cook them.
The chief point of the second paragraph is about ______.
A．the comparison of lean meat and fish
B．the removal of water in food
C．the water content in food
D．the relationship between water and food

The second floor window is usually not very high from the ground. An average person, hanging by the fingertips will have a drop of about six feet to the ground. It is about the height of an average man. Of course, it is safer to jump a short way than to stay in a burning building.
Windows are also useful when you are waiting for help, be sure to keep the door closed before opening the window. Otherwise, smoke and fire may be drawn into the room. Keep your head low at the window to be sure you get fresh air rather than smoke that may have leaked(渗入) into the room.
On a second or a third floor, the best windows for escape are those which open on a roof. From the roof a person can drop to the ground more safely. Dropping onto cement(水泥地) might end in injury. Bushes and grass can help to break a fall.
Which of the following should not be used when trying to escape a fire？
A．windows.
B．elevators.
C．fire escapes.
D．stairways.

The making and care of the gardens and the nursing of the young ants are done by the smallest workers. Slightly larger workers are responsible for chopping up leaves to make them suitable for use in the gardens and for cleaning the nest. A third group of still larger ants do the construction work and collect fresh leaves from outside the nest. The largest are the soldier ants, responsible for defending the nest.
To find out how good the various size-groups are at different tasks, the scientist measured the amount of work done by the ants against the amount of energy they used. He examined first the gathering and carrying of leaves. He selected one of the size-groups, and then measured how efficiently these ants could find leaves and run back to the nest. Then he repeated the experiment for each of the other size-groups. In this way he could see whether any group could do the job more efficiently than the group normally undertaking it.
The intermediate-sized ants that normally perform. this task proved to be the most efficient for their energy costs, but when the scientist examined the whole set of jobs performed by each group of ants it appeared that some sizes of worker ant were not ideally suited to the particular jobs they performed.
In which way are the ants different from other non-human societies？
A．They do not need to search for food.
B．They do not need to look for shelter.
C．Individuals vary in social status.
D．Individuals perform. different functions.
