第3题
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

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.

They say they want to dress as they please，but all of them wear the same clothes. They set off in new directions in music，but all of them end up huddled round listening to the same record. Their reason for thinking or acting in this and that way is that the crowd is doing it.
It has become harder and harder for a teenager to stand up against the popularity wave and go his or her own way. These days every teenager can 1earn from the advertisements what a teenager should have and be. And many of today’s parents have come to award high marks for the popularity of their children.

You may want to listen to classical music instead of going to a party. You may want to collect rocks when everyone else is collecting records.

第10题
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
