Decreases to approximately six hours have been observed among the elderly.

An undergraduate course consists of a series of lectures, seminars and tutorials and, in science and engineering, laboratory classes, which in total account for about 15 hours per week. Arts students may well find that their official contact with teachers is less than this average, while science and engineering students may expect to be timetabled for up to 20 hours per week. Students studying for a particular degree will take a series of lecture courses which run in parallel at a fixed time in each week and may last one academic term or the whole year. Associated with each lecture course are seminars, tutorials and laboratory classes which draw upon, analyze, illustrate or amplify the topics presented in the lectures. Lecture classes can vary in size from 20 to 200 although larger sized lectures tend to decrease as students progress into the second and third year and more options become available. Seminars and tutorials are on the whole much smaller than lecture classes and in some departments can be on a one-to-one basis (that is, one member of staff to one student). Students are normally expected to prepare work in advance for seminars and tutorials and this can take the form. of researching a topic for discussion, by writing essays or by solving problems. Lectures, seminars and tutorials are all one hour in length, whilst laboratory classes usually last either 2 or 3 hours. Much emphasis is put on how to spend as much time if not more studying by themselves as being taught. In the UK it is still common for people to say that they are "reading" for a degree. Each student has a tutor whom they can consult on any matter whether academic or personal. Although the tutor will help, motivation for study is expected to come from the student.
According to the passage, science and engineering courses seem to be more ________than arts courses.
A．motivating
B．varied
C．demanding
D．interesting

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

(5)There is, of course, another side to the question of how to make the best use of one's time at university.(6)This is the case of the student who excels in a particular branch of learning.(7)He is immediately accepted by the university of his choice, and spends his three or four years becoming a specialist, emerging with a first-class Honour Degree and very little knowledge of what the rest of the world is all about.(8)It therefore becomes more and more important that, if students are not to waste their opportunities, there will have to be much more detailed information about courses and more advice.Only in this way can we be sure that we are not to have, on the one hand, a band of specialists ignorant of anything outside of their own subject, and on the other hand, an ever increasing number of graduates qualified in subject for which there is little or no demand in the working world.
