根据下列材料请回答 31～35 题：
A
Now satellites are helping to forecast the weather．They are in space，and they can reach any part of the world．The satellites take pictures of the atmosphere(大气)，because this is where the weather form．They send these pictures to the weather stations．So meteorologists(气象学家)can see the weather of any part of the world．From the pictures，the scientists can often say how the weather will change．
Today，nearly five hundred weather stations in sixty countries receive satellite pictures．When they receive new pictures，the meteorologists compare them with earlier ones．Perhaps they may find that the clouds have changed during the last few hours．This may mean that the weather on the ground may soon change，too．In their next weather forecast，the meteorologists can say this．
So the weather satellites are a great help to the meteorologists．Before satellites were invented，the scientists could forecast the weather for about 24 0r 48 hours．Now they can make good forecasts for three or five days．Soon，perhaps，they may be able to forecast the weather for a week or more ahead．
第 31 题 Satellites travel______．
A．in space
B．in the atmosphere
C．above the ground
D．above space
Losing your ability to think and remember is prettyscary. We know the risk of dementia (痴呆症) increases with age. But if you have memory slips, you probably needn't worry. There are pretty clear differences between signs of dementia andage-related memory loss. After age 50, it's quite common to have trouble remembering the names of people, places andthings quickly, says Dr. Kirk Daffner of Brigham and Women's Hospital in Boston. The brain ages just like the rest of the body. Certain parts shrink, especially areas in the brainthat are important to learning, memory and planning. Changes in brain cells can affectcommunication between different regions of the brain. And blood flow can be reduced asblood vessels narrow. Forgetting the name of an actor in a favorite movie, for example, is nothing to worry about. Butif you forget the plot of the movie or don't remember even seeing it, that's far moreconcerning, Daffner says. When you forget entire experiences, he says, that's "a red flag that something more seriousmay be involved." Forgetting how to operate a familiar object like a microwave oven, orforgetting how to drive to the house of a friend you've visited many times before can also besigns of something going wrong. But even then, Daffner says, people shouldn't panic. There are many things that can causeconfusion and memory loss, including health problems like temporary stoppage of breathingduring sleep, high blood pressure, or depression, as well as medications (药物) likeantidepressants. You don't have to figure this out on your own. Daffner suggests going to your doctor to checkon medications, health problems and other issues that could be affecting memory. And the bestdefense against memory loss is to try to prevent it by building up your brain's cognitive (认知的) reserve, Daffner says. "Read books, go to movies, take on new hobbies or activities that force one to think in novelways," he says. In other words, keep your brain busy and working. And also get physicallyactive, because exercise is a known brain booster.Why does the author say that one needn't be concerned about memory slips？ 1..Why does the author say that one needn't be concerned about memory slips？()

me of medical science. Activists deny that we are trying to help and say it is () of our evil and cruel (). A more reasonable argument, however, can be advanced in our (). Life is often () to animals and human beings. Teenagers are flung from trucks and suffer severe head (). Young children () able to walk find themselves at the bottom of swimming pools while a parent is occupied with something else. From everyday germs to gang (), no life is free of pain. Physicians hoping to relieve the eternal suffering of these tragedies have only three choices: 1) create an animal model of the problem to understand the process and test new therapies; 2) experiment on human beings (some experiments will succeed, most will fail); or 3) leave medical knowledge static, hoping that () discoveries will lead us forward.
Proponents of this innateness theory say that our38for language is inborn, but that language itself develops gradually,39a function of the growth of the brain during childhood.Therefore there are critical40times for language development.Current41of innateness theory are mixed, however, evidence supporting the existence of some innate abilities is undeniable.42, more and more schools are discovering that foreign languages are best taught in43grades.Young children often can learn several languages by being44to them, while adults have a much harder time learning another language once the45of their first language have become firmly fixed.46some aspects of language are undeniably innate, language does not develop automatically in a vacuum.Children who have been47from other human beings do not possess language.This demonstrates that48with other human beings is necessary for proper language development.Some linguists believe that this is even more basic to human language49than any innate capacities.These theorists view language as imitative, learned behavior.50, children learn language from their parents by imitating them.Parents gradually shape their child's language skills by positively reinforcing precise imitations and negatively reinforcing imprecise ones.

Researchers have established that when people are mentally engaged, biochemical changes occur in the brain that allow it to act more effectively in cognitive areas such as attention and memory. This is true regardless of age.
People will be alert and receptive if they are faced with information that gets them to think about things they are interested in. And someone with a history of doing more rather than less will go into old age more cognitively sound than someone who has not had an active mind.
Many experts are so convinced of the benefits of challenging the brain that they are putting the theory to work in their own lives. “The idea is not necessarily to learn to memorize enormous amounts of information,” says James Fozard, associate director of the National Institute on Again. “Most of us don't need that kindof skill. Such specific training is of less interest than being able to maintain mental alertness.” Fozard and others say they challenge their brains with different mental skill, both because they enjoy them and because they are sure that their range of activities will help the way their brains work.
Gene Cohen, acting director of the same institute, suggests that people in their old age should engage in mental and physical activities individually as well as in groups. Cohen says that we are frequently advised to keep physically active as we age, but older people need to keep mentally active as well. Those who do are more likely to maintain their intellectual abilities and to be generally happier and better adjusted. “The point is, you need to do both,” Cohen says. “Intellectual activity actually influences brain-cell health and size.”
6. People who are cognitively healthy are those _______.
A、who can remember large amounts of information
B、who are highly intelligent
C、whose minds are alert and receptive
D、who are good at recognizing different sounds
7. According to Fozards argument people can make their brains work more efficiently by _______.
A、constantly doing memory work
B、taking part in various mental activities
C、going through specific training
D、making frequent adjustments
8. The findings of James and other scientists in their work _________.
A、remain a theory to further proved
B、have been challenged by many other experts
C、have been generally accepted
D、are practiced by the researchers themselves
9. Older people are generally advised to ___________.
A、keep fit by going in for physical activities
B、keep mentally active by challenges through specific training
C、maintain mental alertness through specific training
D、maintain a balance between individual and group activities
10. What is the passage mainly about？
A、How biochemical changes occur in the human brain.
B、Why people should keep active not only physically but also mentally.
C、How intellectual activities influence brain-cell health
D、Why people should receive special mental training as they age.
