Peter: Molly, look at this. The newspaper says we should sort trash.

Peter: {A; B; C; D; E} Many communities have already done that.
Molly: Yeah. The benefits of sorting out trash are obvious.

Molly: If trash is sorted, it can be transferred to factories instead of the disposal plant.
Peter: That makes sense. {A; B; C; D; E}
Molly: With trash separated, pollution caused by incineration can be avoided.

Molly: {A; B; C; D; E} Things like paper, glass, and plastics can all be recycled. They can be reused.
Peter: Sorting is good. {A; B; C; D; E} If people have no idea how to sort their trash, they will still put all waste in the same bag.

Peter: I hope everything goes smoothly!
Molly: I believe it will.
Our skins let us know whether the air is moist or dry, whether surfaces are wet without being sticky or slippery. From the uniformity of slight pressure, we can be aware how deeply a finger is thrust into water at body temperature, even if the Anger is enclosed in a rubber glove that keeps the skin completely dry. Many other animals, with highly sensitive skins, appear to be able to learn still more about their environment. Often they do so without employing any of the five senses.
By observing the capabilities of other members of the animal kingdom, we come to realize that a human being has far more possibilities than are utilized. We neglect ever so many of our senses in concentrating on the five major ones. At the same time, a comparison between animals and man draws attention to the limitation of each sense. The part of the spectrum (光谱) seen by colour-conscious man as red is non-existent for honey-bees. But a bee can see far more in flowers than we, because the ultra-violet (紫外线) to which our eyes are blind is a stimulating (刺激的) part of the insect's spectrum, and, for honey-bees at least, constitutes a separate colour.
From the passage we realize that ______.
A．man possesses far more senses than the five major ones
B．man possesses a few more senses than animals
C．man possesses as many senses as animals
D．man has fully utilized his senses
When we do the wash, it is important to （） white and colored clothing.

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.
A.countless
B.entire
C.separate
D.unique

Meaningfulness affects memory at all levels.Information that does not make any sense to you is difficult to remember.There are several ways in which we can make material more meaningful.Many people, for instance, learn a rhyme to help them remember.Do you know the rhyme "Thirty days has September, April, June, and November..."？ It helps many people remember which months of the year have 30 day s.
Organization also makes a difference in our ability to remember.How useful would a library be if the books were kept in random order？ Material that is organized is better remembered than jumbled information.One example of organization is chunking.C hunking consists of grouping separate bits of information.For example, the number 4671363 is more easily remembered if it is chunked as 467, 13, 63.Categorizing is another means of organization.Suppose you are asked to remember the following list of wor ds: man, bench, dog, desk, woman, horse, child, cat, chair.Many people will group the words into similar categories and remember them as follows: man, woman, child; cat, dog, horse; bench, chair, desk.Needless to say, the second list can be remembered mo re easily than the first one.
Association refers to taking the material we want to remember and relating it to something we remember accurately.In memorizing a number, you might try to associate it with familiar numbers or events.For example, the heigh t of Mount Fuji in Japan -12,389 feet -might be remembered using the following associations: 12 is the number of months in the year, and 389 is the number of days in a year (365) added to the number of months twice (24).
The last principle is visualizati on.Research has shown striking improvements in many types of memory tasks when people are asked to visualize the items to be remembered.In one study, subjects in one group were asked to learn some words using imagery, while the second group used repetiti on to learn the words.Those using imagery remembered 80 to 90 percent of the words, compared with 30 to 40 percent of the words for those who memorized by repetition.Thus forming an integrated image with all the information placed in a single mental pict ure can help us to preserve a memory.
