[单项选择] Our multimillion nerve-cell central nervous system has its roots in the scattered nerve cells of tiny, lowly organisms that lived in water half a billion years ago. Nerve cells evidently first appeared in coelenterates —"hollow-gutted" organisms like hydra and the sea anemone. A coelenterate’’s nerve network lacks any kind of centralized control. This probably began with flatworms — the first creatures to possess a head, specialized sense cells help flatworms respond more flexibly than sea anemones to outside stimulus. But like most animals without a backbone, flatworms act mostly by instinct and reflex.
Intelligent behavior remained impossible until the appearance of relatively big, complex types of brain — the types we find among the backboned animals, or vertebrates. The tiniest fish has a larger brain than the largest insect. But the development of a fish’’s three-part brain reflects that beast’’s unin-tellectual priorities. Much of the forebrain deals only with smell. Th

Although our educational system and our society generally place a high value on competition, some problems can be better solved through cooperation and some forms of learning are strengthened through cooperation. Both competition and cooperation have a place in society and can serve a useful purpose. Consequently, it is necessary to be able to engage in both processes depending on the circumstances and one’s goals.
In the academic environment grades are often conceived as the major criterion (标准) for the assessment of learning. We tend to assume that the higher one’s grade average, the more one has learned, thus creating greater competition for grades. This competition can be particularly intense in fields where the financial rewards are great and opportunity is limited: law, engineering, medicine, and business.
However, the measure of one’s learning is not limited to grades. It is possible to learn a great deal about a subject and receive a low

Higher education and our university system seem to be in the news constantly. John O’Leary, editor of the Good University Guide, thinks that universities may secretly be pleased by falling numbers.
Universities all over the country are preparing themselves for the possibility of empty places when fees are ￡9,000 a year. At the same time, some of the UK’s best-known academics are staking their reputations--and some of their own money--on students paying ￡18,000 a year.
Why it should cost ￡18,000 a year to provide the cheapest subjects in higher education with visiting lecturers and few of the facilities offered by other universities is a mystery. But the big names and exclusivity might attract enough rich overseas students to see it through what will surely be a difficult opening period.
There will not be enough of either to comfort all the existing universities. Those at the top can afford a 10 per cent drop in applications and still have plent

C. Some of the most famous scholars in the UK are found taking bribes.
D. The tuition fee for college has been proposed to rise to ￡18,000 a year.
[简答题] In our system of education today, examinations are a common feature. Our present education system has often been criticized as too examination-oriented. However, one must remember that in offices and other areas of work, examinations still feature clearly. There is no doubt that the fear and influence of examinations cause much preparation work. So it appears that examinations, whether considered good or bad, would stay for a while as a test of human knowledge.
Examinations are meant to test the intellect of a person, how much he knows or how he has learnt from a particular course. It is designed to make students study, which should be their immediate mission in life. In our competitive world of today, examinations have a highly selecting or filtering role. In the university, students have to pass annual examinations before they are allowed to continue, or study a harder syllabus. The examination results would show whether the student is ready to start the next phase of his co
