Research experience is an essential element of hiring and promotion at the research university because it is the emphasis on research that distinguishes such a university from an arts college. Some professors, however, neglect teaching for research, and that presents a problem.
Most research universities reward outstanding teaching, but the greatest recognition is usually given for achievements in research. Part of the reason is the difficulty of judging teaching. A highly responsible and tough professor is usually appreciated by top students who want to be challenged, but disliked by those whose records are less impressive. The mild professor gets overall ratings that are usually high, but there is a sense of disappointment on the part of the best students, exactly those for whom the system should present the greatest challenges. Thus, a university trying to promote professors primarily on the basis of teaching qualities would have to confront this confusion.
As modem science moves faster, two forces are exerted on professors: one is the time needed to keep up with the profession; the other is the time needed to teach. The training of new scientists re quires outstanding teaching at the research university as well as the arts college. Although scientists are usually "made" in the elementary schools, scientists can be "lost" by poor teaching at the college and graduate school levels. The solution is not to separate teaching and research, but to recognize that the combination is difficult but vital. The title of professor should be given only to those who profess, and it is perhaps time for universities to reserve it for those willing to be an earnest part of the community of scholars. Professors unwilling to teach can be called "distinguished research investigators, "or something else.
The pace of modem science makes it increasingly difficult to be a great researcher and great teacher. Yet many are described in just those terms. Those who say we can separate teaching and re search simply do not understand the system, but those who say the problem will disappear are not fulfilling their responsibilities.
What idea does the author want to convey in the first paragraph？
A．It is wrong to overestimate the importance of teaching.
B．Teaching and research are contradictory to each other.
C．Research can never be emphasized too much.
D．The relationship between teaching and research should not be simplified.

The latest finding comes from nutrition and immunology respected: Vitamin E boosts the immune system in older people. In an eight-month study of 88 seniors, the scientists found that those taking at least 200 international units of Vitamin E daily had stronger immune responses than those taking little or none. Alzheimer's disease. Researchers tracked 341 moderately senile patients. Those who popped 2,000 IU of Vitamin E took seven months longer to reach an advanced stage of the disease.
Rangit Kumar Chandra, a Vitamin E researcher at Memorial University of Newfoundland, Canada, says more studies are needed to learn who can benefit most and at what dose. Vitamin E thins the blood, so high doses can cause bleeding in people who also take blood thinning drags, even aspirin. Individuals with serious conditions should consult their doctors. But most people over 65, Chandra says, can take up to 200 IU with no side effects and great benefits.
What's the main idea of the passage？
A．People will be in perfect health if they take Vitamin E every day.
B．Study showed that people who took Vitamin E regained their Flexibility.
C．Vitamin E may help prevent Alzheimer's.
D．Vitamin E offers a range of advantage if old people take proper dose of Vitamin E every day.
