Memory is said to be stored in the brain as a "memory trace (记忆痕) ". What makes up this trace is not known. Some scientists believe that certain chemical substances may carry certain memories. For example, one substance, when given to rats, causes them to fear the dark.
Other research into memory has to do with how the brain works. Psychologists use three means to find out bow a person remembers. For example, give a person a grocery list. Let the person memorize the list, then put it away. The most natural way to find out how much a person remembers of the grocery list is to ask what he or she remembers. This is called the method of recall. Another method is called recognition. Give the person another grocery list. Ask him or her to choose items on the first list from the items that are on only the second list. Often a person will be able to recognize things that he or she cannot recall. A third method of finding how much a person remembers is called relearning. Here the person is asked to read over the first list. The person will probably learn the list the second time faster than he did the first time. The difference in the time it takes to relearn the list is thought of as measure of how much a person has remembered.
One way of remembering something is to repeat it many times. Interest is very important. Boring lists of facts are much more difficult to remember than something that we understand and are interested in. Motivation, or wanting to do something, is also important. Motivation is linked with reward. For example, a hungry animal quickly learns how to do something if that action gets the animal food. In humans, wanting to learn is often motivation. The praise of a teacher or the knowledge that an answer is correct is rewarding.
We can learn from the 2nd paragraph that ______.
A．bad memories may cause rats to fear the dark
B．it is hard to tell what a memory trace consists of
C．chemical substances carry certain memories
D．memory is stored in the brain as a substance

The moon is about 384 000 kilometers away from the earth. A plane can not fly to the moon because the air reaches only 240 kilometers high above the earth. Then there is no air. But something can fly even when there is no air. That is' a rocket (火箭).
Rockets can fly out into space. Rockets with men in them have already reached the moon. Some rockets without men in them have flown to other parts, much farther away from the earth than the moon in the universe. One day, rockets may be able to go to any place.
Scientists knew ______ about the moon a long time ago.
A．nothing
B．many things
C．everything
D．little
As hard as【60】may be, sit back and chill, experts advise. Though you've got to get them to do it,【61】helping too much, or even examining【62】too carefully, you may keep them【63】doing it by themselves. "I wouldn't advise a parent to check every【64】assignment, " says psychologist John Rosemond, author of Ending the Tough Homework. "There's a【65】of appreciation for trial and error. Let your children【66】the grade they deserve.
Many experts believe parents should gently look over the work of younger children and ask them to rethink their【67】. But"you don't want them to feel it has to be【68】, " they say.
That's not to say parents should【69】homework—first, they should monitor how much homework their kids【70】. "Thirty minutes a day in the early elementary years and an hour in【71】four, five, and six is standard, " says Rosemond. For junior-high students it should be "【72】more than an hour and a half, and two for high-school students. " If your child【73】has more homework than this, you may want to check【74】other parents and then talk to the teacher about【75】assignments.

Contrary to what many people believe, highly intelligent children are not necessarily bound to have an academic success. In fact, so-called gifted students may fail to do well because they are unusually smart. Ensuring that a gifted child reaches his or her potential requires an understanding of what can go wrong and how to satisfy the unusual learning requirements of extremely bright young people.
One common problem gifted kids face is that they, and those around them, place too much importance on being smart. Such an emphasis can breed a belief that bright people do not have to work hard to do well. Although smart kids may not need to work hard in the lower grades when the work is easy, they may struggle and perform. poorly when the work gets harder because they do not make the effort to learn. In some cases, they may not know how to study, having never done it before. In others, they simply cannot accept the fact that some tasks require effort.
If the scholastic achievement of highly intelligent children remains below average for an extended period, many teachers will fail to recognize their potential. As a result, such students may not get the encouragement they need, and may further be depressed to learn. They may fall far behind in their schoolwork and even develop behavior. problems. Boys may turn aggressive or become class clowns(小丑).Girls often develop performance anxiety and other symptoms such as stomachaches.
One way to avoid such difficulties is to recognize that IQ is just one of the elements for success. Children do well or struggle in school for a host of reasons apart from IQ, according to psychologist Franz Monks of the University of Nijmegen in the Netherlands. These include motivation and persistence, social competence, and the support of family, educators and friends. Emphasizing the importance of persistence and hard work, for example, will help a child avoid the laziness trap. Gifted children also need intellectual challenges-to teach them how to work hard.

Culture shock is an occupational disease (职业病) for people who have been suddenly transplanted abroad.
Culture shock is caused by the anxiety that results from losing all familiar signs and symbols of social intercourse. Those signs are as following: How to shake hands and what to say when meeting people, when and how to give tips, how to make purchases, when to accept and refuse invitations, when to take statements seriously and when not. These signs, which may be words, gestures, facial expressions, or customs, are acquired by all of us in the course of growing up and as much a part of our culture as the language we speak or the beliefs we accept. All of us depend on hundreds of these signs for the peace of our mind and day-to-day efficiency, but we do not carry most at the level of conscious awareness.
Now when an individual enters a strange culture, all or most of these familiar signs are removed. No matter how broadminded or full of good will you may be, a series of supports have been knocked from under you, followed by a feeling of frustration. When suffering from culture shock people first reject the environment which causes discomfort. The ways of the host country are bad Because they make us feel bad. When foreigners on a strange land get together to complain about the host country and its people, you can be sure that they are suffering from culture shock.
According to the passage, culture shock is______.
A．an occupational disease of foreign people
B．may lead to very serious symptoms
C．actually not a disease
D．incurable
For example, in France, business meetings begin promptly at the designated time and everyone is expected to be there. Foreign business people who are tardy are often left outside to cool their heels as a means of letting them know the importance of promptness. Unless one is aware of such expected behaviors he may end up insulting the people with whom he hopes to establish trade relations.
A second traditional problem is that of monetary conversions. For example, if a transaction is conducted with Russia, payment may be made in rubles. Of course, this currency is of little value to the American firm. It is, therefore, necessary to convert the foreign currency to American dollars. How much are these Russian rubles worth in terms of dollars？ This conversion rate is determined by every market, where the currencies of countries are bought and sold. Thus there is an established rate, although it will often fluctuate from day to day. For example, the ruble may be worth '0.75 on Monday and '0.72 on Tuesday because of an announced wheat shortage in Russia. In addition, there is the dilemma associated with converting at '0.72. Some financial institutions may be unwilling to pay this price, feeling that the ruble will sink much lower over the next week. As a result, conversion may finally come at '0.69. These "losses" must be accepted by the company as one of the costs of doing business overseas.
A third unique problem is trade barriers. For one reason or another, all countries impose trade barriers on certain goods crossing their borders. Some trade barriers are directly related to exports. For example, the United States permits strategic military material to be shipped abroad only after government permission has been obtained. Most trade barriers, however, are designed to restrict import. Two of the most common import barriers are quotas and tariffs.
The best title for the passage would be ______.
A．How to Succeed in International Trade
B．Monetary Conversion
C．Trade Barriers
D．Unique Problems in International Trade
