Section A
Directions: In this section, there is a passage with ten blanks. You are required to select one word for each blank from a list of choices given in a word bank following the passage. Read the passage through carefully before making your choices. Each choice in the bank is identified by a letter. Please mark the corresponding letter for each item on Answer Sheet 2 with a single line through the centre. You may not use any of the words in the bank more than once.
Physical activity does the body good, and there's growing evidence that it helps the brain too. Researchers in the Netherlands report that children who get more exercise, whether at school or on their own, to have higher GPAs and better scores on standardized tests. In a of 14 studies that looked at physical activity and academic , investigators found that the more children moved, the better their grades were in school, 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 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. 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 exclusive. Physical activity can improve blood to the brain, fueling memory, attention and creativity, which are to learning. And exercise releases hormones that can improve and relieve stress, which can also help learning. So while it may seem as if kids are just exercising their bodies when they're running around, they may actually be exercising their brains as well.

Passage One
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 do 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 morals, and how to create a set of ethical rules. But if we come up with an answer, robots could be good for humanity.
Passage Two
Why do some people live to be older than others? You know the standard explanations: keeping a moderate diet, engaging in regular exercise, etc. But what effect does your personality have on your longevity (长寿)? Do some kinds of personalities lead to longer lives? A new study in the Journal of the American Geriatrics Society looked at this question by examining the personality characteristics of 246 children of people who had lived to be at least 100.
The study shows that those living the longest are more outgoing, more active and less neurotic (神经质的) than other people. Long-living women are also more likely to be sympathetic and cooperative than women with a normal life span. These findings are in agreement with what you would expect from the evolutionary theory: those who like to make friends and help others can gather enough resources to make it through tough times.
Interestingly, however, other characteristics that you might consider advantageous had no impact on whether study participants were likely to live longer. Those who were more self-disciplined, for instance, were no more likely to live to be very old. Also, being open to new ideas had no relationship to long life, which might explain all those bad-tempered old people who are fixed in their ways.
Whether you can successfully change your personality as an adult is the subject of a longstanding psychological debate. But the new paper suggests that if you want long life, you should strive to be as outgoing as possible.
Unfortunately, another recent study shows that your mother's personality may also help determine your longevity. That study looked at nearly 28,000 Norwegian mothers and found that those moms who were more anxious, depressed and angry were more likely to feed their kids unhealthy diets. Patterns of childhood eating can be hard to break when we're adults, which may mean that kids of depressed moms end up dying younger.
Personality isn't destiny (命运), and everyone knows that individuals can learn to change. But both studies show that long life isn't just a matter of your physical health but of your mental health.
