2. Passage Twenty-Six Today just as technology changed the face of industry， farmers have undergone an “agricultural revolution” . On the farm of today， machines provide all the power. One of the most important benefits will be the farm computer. A few forward-looking farmers are already using computers to help them run their farms more efficiently. The computers help them keep more accurate records， so they can make better decisions on what crops to plant， how much livestock to buy， when to sell their products， and how much profit they can expect. Many computer companies have been developing special computer programs just for farmers. Programs are being written for hog (猪) producers， grain farmers， potato farmers， and dairy farmers. In the future， farmers will be able to purchase computer programs made to their needs. Because of the growing importance of computers on the farm， students at agricultural colleges are required to take computer classes in addition to their normal agricultural courses. There can be no doubt that farmers will rely on computers even more in the future. While the old-time farm depended on horse power， and modern farms depend on machine power， farms of the future will depend on computer power. Another technological advance which is still in the experimental stage is the robot， a real “mechanized hired hand” that will be able to move and， in some ways， think like a human being. Agricultural engineers believe that computer-aided robots will make startling changes in farming before the end of the century. Unlike farmers of the present， farmers of the future will find that many day-to-day tasks will be done for them. Scientists are now developing robots that will be able to shear (修剪) sheep， drive tractors， and harvest fruit. Even complex jobs will be done by robots. For example， in order to milk their cows， farmers must first drive them into the special barn (畜棚)， then connect them to the milking machines， watch the machines， and disconnect them when they are finished. In the future， this will all be done by robots. In addition， when the milking is completed， the robots will automatically check to make sure that the milk is pure. The complete mobilization of the farm is far in the future， but engineers expect that some robots will be used before long. According to the passage， computers can not help farmers decide ( ) .

3. Passage One There are three separate sources of danger in supplying energy by nuclear power. First， the radioactive material must travel from its place of production to the power station. Although the power stations themselves are strongly built， the containers used for the transport of the materials are not. Normally， only two methods of transport are in use， namely road or rail. Unfortunately， both of these may have an effect on the general public， since they are sure to pass near， or even through， heavily populated areas. Second， there is the problem of waste. All nuclear power stations produce wastes that in most cases will remain radioactive for thousands of years. It is impossible to make these wastes nonradioactive， so they must be stored in one of the inconvenient ways that scientists have invented. For example， they may be buried under the ground， or dropped into deserted mines， or sunk in the sea. However， these methods do not solve the problem， since an earthquake could easily break the containers.
Third， there may occur the danger of a leak or an explosion at the power station. Compared with the other two dangers， this is not very likely， so it does not provide a serious objection to the nuclear program. However， it can happen. Separately， these three types of dangers are not a great cause for worry. Taken together， though， the probability of disaster is extremely high. What do we learn from the last paragraph?

A. By itself， none of the three dangers is very likely to cause much worry.

B. The dangers of nuclear energy can be prevented.

C. The general public are strongly against the nuclear program.

D. The power station is a safe place.

4. Passage Six 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 (把 …按能力分班) pupils. 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 (智力的) ability. This is only one aspect of their total personality. 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 co-operate， to share， and to develop leadership skills. They also learn how to cope with personal problems as well as 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 doesn’t 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. The pupils often work in groups: this gives them the opportunity to learn ( ) .

A. to cooperate， to share and to develop leadership skills

B. to cope with personal problems

C. to learn how to think， to make decisions， to analyze and evaluate， and to communicate effectively

D. to do all the above things
