[填空题]Questions 47 to 51 are based on the following passage.
On March 18,1965, Leonov, the Russian astronaut, walked in outer space for the first time. Several months later, a similar feat was performed by the first American astronaut. Both of these space walkers had spent months previous to their flights learning how to control their movements under the strange conditions which exist in space. Wearing their thick space suits, they learned to deal with an environment where there is neither weight nor gravity, neither up nor down.
We don’t realize how much we depend on the earth’s gravity until we are deprived of it. Then our feet no longer stay on the ground; we float around in the air, the slightest touch may send us drifting off in the opposite direction.
In the laboratories where astronauts are trained for their journeys, they are subjected to conditions that resemble those of flight. It takes time for them to prepare for the great changes that occur

[单项选择] Questions 57 to 61 are based on the following passage.
Google must be the most ambitious company in the world. Its stated goal, "to organize the world’s information and make it universally accessible and useful," deliberately omits the word "web" to indicate that the company is reaching for absolutely all information everywhere and in every form. From books to health records and videos, from your friendships to your click patterns and physical location, Google wants to know. To some people this sounds uplifting, with promises of free access to knowledge and help in managing our daily lives. To others, it is somewhat like another Big Brother, no less frightening than its totalitarian (极权主义的) ancestors for being in the private information.
Randall Stross, a journalist at the New York Times, does a good job of analyzing this un bounded ambition in his book "Planet Google". One chapter is about the huge data centers that Google is building with a view to sto

[填空题] Questions 47 to 51 are based on the following passage.
Japanese firms have achieved the highest levels of manufacturing efficiency in the world auto mobile industry. Some observers of Japan have assumed that Japanese firms use the same manufacturing equipment and techniques as United States firms but have benefited from the unique characteristics of Japanese employees and the Japanese culture. However, if this were true, then one would expect Japanese auto plants in the United States to perform no better than factories run by United States companies. This is not the case. Japanese-run automobile plants located in the United States and staffed by local workers have demonstrated higher levels of productivity when compared with factories owned by United States companies.
Other observers link high Japanese productivity to higher levels of capital investment per worker. But a historical perspective leads to a different conclusion. When the two top Japanese automobil

[单项选择]Questions 62 to 66 are based on the following passage.
For some time past it has been widely accepted that babies-and other creatures-learn to do things because certain acts lead to “rewards”; and there is no reason to doubt that this is true. But it used also to be widely believed that effective rewards, at least in the early stages, had to be directly related to such basic physiological (生理的)“drives” as thirst or hunger. In other words, a baby would learn if he got food or drink or some sort of physical comfort, not otherwise.
It is now clear that this is not so. Babies will learn to behave in ways that produce results in the world with no reward except the successful outcome.
Papousek began his studies by using milk in the normal way to“reward” the babies and so taught them to carry out some simple movements, such as turning the head to one side or the other. Then he noticed that a baby who had had enough to drink would refuse the milk but wou
A. would make learned responses when it saw the milk

D. would turn its head to right or left when it had enough to drink
