题目列表(包括答案和解析)

 A film was at the Circle Five Ranch to film a Marlboro commercial. This is in 1868, before they prohibited cigarette ads from American television. Darrell Winfield was watching the crew set up the equipment. The scene included an actor crossing a river on horseback, but when the time came to shoot, the man was too drunk to ride. Someone from the crews saw Winfield and asked him if he would ride the horse for  50. “Hell, ” said Winfield, “for 50 bucks, I'll jump that damn horse over the moon!”

  A. slows down all the time

  B. speeds up all the time

  C. speeds up part of the time and slows down part of the time

  D. moves at a constant speed

  66.As the diagram shows, there is a fixed superconductor ring, on the right of which lies a bar magnet. There is no electric current. When the magnet is moved to the right, because of electro-magnetic, induction, a certain electric current is produced. Thus the direction of the electric current is________ .

   A. as indicated by the arrowhead in the diagram. When the magnet is moved away, the electric current will soon disappear.

  B. as indicated by the arrowhead in the diagram. When the magnet is moved away, the electric current will still remain.

  C. in the opposite direction. When the magnet is moved away, the electric current will soon disappear.

D. in the opposite direction. When the magnet is moved away, the electric current will still remain.

As you dash outdoors in the middle of winter, you might make it halfway down the block before realizing that your ears are freezing because you forgot your hat.

Now, scientists have shown that even though you’ve had an apparent memory lapse(丧失), your brain never forgot what you should have done.

Memory works mainly by association. For example, as you try to remember where you left your keys, you might recall you last had them in the living room, which reminds you that there was an ad for soap on television, which reminds you that you need soap, and so on. And then, as you’re heading out of the door to buy soap, you remember that your keys are on the kitchen counter. Your brain knew where the keys were all along. It just took a round-about way to get there.

Now, scientists at the Salk Institute for Biological Studies are studying associative memory in monkeys to figure out just how this complicated process works.

First, the researchers trained a group of monkeys to remember arbitrary(任意的) pairs of symbols. The researchers showed the monkeys one symbol(cold weather) and then gave them the choice of two other symbols, one of which (a hat) would be associated with the first. A correct choice would earn them a sip of their favorite juice.

Most of the monkeys performed the test perfectly, but one kept making mistakes.

“We wondered what happened in the brain when the monkey made the wrong choice, although it apparently learned the right pairing of symbols,” said study leader Thomas Albright.

Albright and his team observed signals from the nerve cells in the monkey’s inferior temporal cortex (ITC), an area of its brain used for visual pattern recognition and for storing this type of memory.

As the monkey was deciding which symbol to choose, about a quarter of the activity in the ITC was due to the choice behavior.

Meanwhile, more than half the activity was in a different group of nerve cells, which scientists believe represent the monkey’s memory of the correct symbol pairing, and surprisingly, these cells continued to work well even when the monkey chose the wrong symbol.

“In this sense, the cells ‘knew’ more than the monkeys let on in their behavior,” Albright said. “Thus, behavior may vary, but knowledge endures.”

1. What is the main idea of this passage?

A. Your brain remembers what you forget.

B. Activity is a round-about way to memory.  

C. Monkeys have better memory than us.

D. Your brain may forget something, but not always.

2. The example of the keys and soap is given to explain the relationship between _______.

A. memory and our daily life            B. memory and television ads

C. memory and association               D. memory lapse and human brain

3.The researchers believe the monkey that made the wrong choice ________.

A. had some trouble with its nerve system             B. failed to see the objects well

C. had the worst memory                 D. also knew the correct answer

4. The underlined word “endures” may be best replaced by __________.

A. increases        B. remains      C. disappears       D. improves

Living one’s life is really like driving on a highway. First, the driver must carefully examine the  

41   of his car, just as he cares for his health for a good life . Once he enters into the highway, he must    42   certain rules for his own safety. It can also be said that he must obey certain rules of society when living as a   43   adult. For example, on the highway, he is required to keep a   44   speed which can be compared with his continuous activities through his life. Neither driving nor living must be taken at too high a speed nor at too slow a speed. If he drives too 45 , the police will give him a ticket, just as he will be arrested when he breaks the law. Acting too conservatively, he will be called an out-of-date person  46   the others driving at the proper speed. When he wants to   47   lanes, he must give careful attention to every direction of his car . It is sometimes dangerous to change the way of life unless he can be sure of completion by doing so. He should not make any unnecessary changing of lanes which gives him only danger.

Finally, he must discover where he is now by   48   some signs appearing now and then. If he takes the wrong turning, he must return to the right path as soon as he can. But he may   49 lose time and energy both on the road and in life.

On the whole, driving on a highway and living one’s life are both hard work. But if he is careful and serious enough, they will provide him much pleasure.
