Section A
Directions : There are 4 passages in this part . Each passage is followed by some questzons or unfinished statements. For each of them there are four choices marked A , B , C and D. You should decide on the best choice and blacken the corresponding letter on the Answer Sheet with a pencil.
Questions 21 to 24 are based on the following passage:
Americans like to do business without leaving their cars. You'11 see drive - in banks, drive-in restaurants, drive in churches and 4rive - in movies .
When driving in the U. S. , it’s a good idea to have in international driver's license if you don' t have a state license . Each of the fifty states has its own traffic laws. Get information when youcross the border into a state at a tourist information center.
There is a national speed limit of 55 miles per hour. Americans are generally polite about lettingcars enter busy streets. They usually stop for people who are walking to let them cross the street. Inmany states you may turn right after stopping at a corner, even if there is a red light. On some roadsthere may be a minimum speed.
If you rent a car, ask the company what to do in case your car breaks down. Some companies will ask you to call a special number. Others will want you to have the car repaired. They will partly deduct the cost of the repair from your bill.
"Mileage" can mean two things. It may mean the total number of miles a car has been driven. We say "This car only has 10 ,000 miles on it; it has low mileage." On the other hand , "gas mileage" is the number of miles a car can travel on one U. S. gallon of gas. For example , a big car that gets 25 miles to the gallon gets very good mileage. A small economy car should get at least 35 miles to the gallon when it's new.

Questions 25 to 28 are based on the following passage :
There are robots all around us. Some do very complicated jobs like flying airplanes and driving subway trains. And some do a simple job.
When an automatic washing machine is switched on, water pours in. The machine waits until the water is hot before washing the clothes. It does this by"feedback."Information about whatis happening is "feedback"into the robot to tell it what to do next.
Our eyes , ears and other senses are our feedback . They tell us what is going on around us. So robots are like people in two ways. They work and they have feedback.
There are robots all around, making our lives easier. Some of them , like the pocket calculator, can work much more quickly than human beings can. And they rarely make mistakes.
In some ways robots are better than people. They work quickly, but do not make mistakes. They do not get bored doing the same job over and over again. And they never get tired .
Robots are very useful in factories. They can be taught to do many different jobs. First their electronic brains must be shown how the job is done . A person moves the robot'"arm"and "hand"through each part of the job. The robot's brain remembers each move. When the robot is put to work on its own , its brain controls the rods , wheels and motors which move its arm.
When the robot is needed for a new job, its electronic memory is "wiped clean."Then it is taught how to do its new task.
If the robot's hand stops working, or if something gets in the way, it cannot do the next part of the job. So it stops and signals for help. Then a human engineer repairs it.
The most ``intelligent'' robots can move and see. Their eyes are cameras. Their metal fingers can feel shapes and even find out how hot and cold objects are . These robots have computer brains ,linked to their eyes and fingers , which control their actions.
