单选题 Basketball is still a young game. in the winter or 1891, a certain college was having trouble with its boy students. The weather was so terrible that the students had to stay indoors. Since they could not enjoy their sports outside as usual, they were unhappy, and some of them often got into fights from time to time. Finally, one of the teachers at the college, J. E. Naismith, was asked to invent a new game for the students. It was not an easy job because such a game had to be played indoors, and the court was not very large. Naismith thought for a few days and invented a kind of ball game. It was a fast. exciting game with much moving and passing of the ball. It was played between two teams. To make score, the ball had to be thrown into a basket ten feet high above the floor on the wail. At each end of the court there was such a basket. At first, Naismith had planned to have the ball thrown into a box. As he could not find boxes of the right size, he had to use fruit basket in- stead. That is how the game got its name.

单选题 Students all over the world have to work for their education. A college education in the United States is expensive. The costs are so high that most families begin to save for their children's education when their children are babies. Even so, many young people cannot afford to pay the expenses of full-time college work. They do not have enough money to pay for school costs. Tuition for attending the university, books for classes, and living expenses are high. There are other expenses such as chemistry and biology lab fees and special student activity fees for such things as parking permits and football tic, kets. The cost of college education increases every year. However, classrooms are still crowded with students. Some American students have scholarships or other support, but many do not. Students from other countries have money problems to overcome, too. Because students in most international programs need to have a sponsor, they work hard to earn scholarships or special loans. International students understand the value of going to school in another country. They also know that it is difficult. Yet just as Americans choose to attend American universities in spite of the difficulty, however, it is usually possible for students from abroad to work on university campuses to pay for some of the costs of their education. Some people believe that students value their education more if they work for it.

单选题 Memory is the ability to keep track of things that have happened in the past. Memory really is learning. One needs memory to ride a bicycle. A dog needs to remember if it is to come when called. 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.
