单选题Between 1977 and 1981, three groups of American women, numbering 27 in all, between the age of 35 and 65, were given month-long tests to determine how they would respond to conditions resembling those aboard the space shuttle. Though carefully selected from among many applicants, the women were volunteers and the pay was barely above the minimum wage. They were not allowed to smoke or drink alcohol during the tests, and they were expected to tolerate each others company at close quarters for the entire period. Among other things they had to stand pressure three times the force of gravity and carry out both physical and mental tasks whole exhausted from strenuous physical exercise. At the end of ten days, they had to spend a further twenty days absolutely confined to bed, during which time they suffered backaches and other discomforts, and when they were finally allowed up, the more physically active women were especially subject to pain due to a slight calcium loss. Results of the tests suggest that women will have significant advantages over man in space. They need less food and less oxygen and they stand up to radiation better. Men's advantages in terms of strength and stamina, meanwhile, are virtually wiped out by the zero-gravity condition in space.

单选题When an art museum wants a new exhibit, it buys things in finished form and hangs them on its walls. When a natural history museum wants an exhibit, it often must build it realistically---from a mass of material and evidence brought together by careful research. An animal, for example, must first be skinned. Photographs and measurements are used to determine the animal"s structure in a natural position---fighting, resting, or feeding. Then muscle forms are built and a plaster shell is made. Finally the skin is pulled over the shell like a wet glove. This completes the animal subject. Displaying such things as stone heads, giant trees, and meteorites is basically mechanical. Most other natural history exhibits present more difficult problems. For instance, how can a creature be exhibited when it is too small to be seen clearly? In these cases, larger-than-life models are built. The American Museum of Natural History has models of fleas, houseflies, and many other insects enlarged up to seventy-four times. The models show the stages of the insects" development and the workings of their bodies.
