In a 　27　of 14 studies that looked at physical activity and academic　28　, investigators found that the more children moved, the better their grades were in school, 　29　in the basic subjects of math, English and reading.

The data will certainly fuel the ongoing debate over whether physical education classes should be cut as schools struggle to 　30　on smaller budgets. The arguments against physical education have included concerns that gym time may be taking away from study time. With standardized test scores in the U.S.　31　in recent years, some administrators believe students need to spend more time in the classroom instead of on the playground. But as these findings show, exercise and academics may not be 　32　exclusive. Physical activity can improve blood 　33　to the brain, fueling memory, attention and creativity, which are 　34　to learning. And exercise releases hormones that can improve 　35　and relieve stress, which can also help learning.

试卷一仔细阅读(文都教育版)

Passage one

Questions 46 to 50 are based on the following passage.

As Artificial Intelligence(AI) becomes increasingly sophisticated, there are growing concerns that robots could become a threat. This danger can be avoided, according to computer science professor Stuart Russell, if we figure out how to turn human values into a programmable code.

Russell argues that as robots take on more complicated tasks, it’s necessary to translate our morals into AI language.

For example, if a robot does chores around the house, you wouldn’t want it to put the pet cat in the oven to make dinner for the hungry children. “You would want that robot preloaded with a good set of values,” said Russell.

Some robots are already programmed with basic human values. For example, mobile robots have been programmed to keep a comfortable distance from humans. Obviously there are cultural differences, but if you were talking to another person and they came up close in your personal space, you wouldn’t think that’s the kind of thing a properly brought-up person would do.

It will be possible to create more sophisticated moral machines, if only we can find a way to set out human values as clear rules.

Robots could also learn values from drawing patterns from large sets of data on human behavior. They are dangerous only if programmers are careless.

The biggest concern with robots going against human values is that human beings fail to so sufficient testing and they’ve produced a system that will break some kind of taboo(禁忌).

One simple check would be to program a robot to check the correct course of action with a human when presented with an unusual situation.

If the robot is unsure whether an animal is suitable for the microwave, it has the opportunity to stop, send out beeps(嘟嘟声), and ask for directions from a human. If we humans aren’t quite sure about a decision, we go and ask somebody else.

The most difficult step in programming values will be deciding exactly what we believe in moral, and how to create a set of ethical rules. But if we come up with an answer, robots could be good for humanity.

does the author say about the threat of robots?

A)It may constitute a challenge to computer progranmers.

B)It accompanies all machinery involving high technology.

C)It can be avoided if human values are translated into their language.

D)It has become an inevitable peril as technology gets more sophisticated.

would we think of a person who invades our personal space according to the author?

A)They are aggressive.

B)They are outgoing.

C)They are ignorant.

D)They are ill-bred.

do robots learn human values?

A)By interacting with humans in everyday life situations.

B)By following the daily routines of civilized human beings.

C)By picking up patterns from massive data on human behavior.
