subway trains. and some do one simple job. When an automatic washing machine is switched on,
water pours in. The machine waits until the water is warm enough for washing clothes. It does this by
"feedback"(反馈). Information about what is happening is feedback into the robot to tell what to do
next. Our eyes, ears and other senses are our feedback. They tell us what is going on around us. So
robots are like human beings in two ways. They work and they have feedback.
In some ways robots are better than human beings. They work quickly and do not make mistakes.
They do not get bored doing the same job over and over again. And they never get tired. So robots are
very useful in factories. They can be taught to do many different jobs. First their electronic brain must be
shown how the job is done. A person moves the robot"s "arms" and "hands" through each part of the job.
The most intelligent robots can move and see. Their eyes are cameras. Their fingers can feel shapes
and sizes of the objects. These robots have computer brains linked to their eyes and fingers, which
control their actions. The expensive robots are used in scientific research. They do such job as handling
radioactive materials.
B. there are various kinds of robots
C. we see robots only at certain times
D. robots can be easily controlled
B. They will probably take over in the future.
C. They are very helpful and useful to humans.
D. They are machines that break down a lot.

getting a college degree, new studies suggest in the latest effort to examine the effects of television
on children．
One of the studies looked at nearly 400 northern California third-graders．Those with TVs in
their bedrooms scored about eight points lower on math and language arts tests than children
without bedroom TVs．
A second study, looking at nearly 1000 grown-ups in New Zealand,found lower education
levels among 26-year-olds who had watched lots of TV during childhood．But the results don"t
prove that TV is the cause and don"t rule out(排除) that already poorly motivated(有动机的)
youngsters may watch lots of TV.
Their study measured the TV habits of 26-year-olds between ages 5 and 15. Those with
college degrees had watched an average of less than two hours of TV per weeknight during
childhood, compared with an average of more than 2.5 hours for those who had no education
beyond high schools．
In the California study, children with TVs in their rooms but no computer at home scored the
lowest, while those with no bedroom TV but who had home computers scored the highest．
While this study does not prove that bedroom TV sets caused the lower scores,it adds to
accumulating(增加) findings that children shouldn"t have TVs in their bedrooms．
B. not be interested in math
C. be unable to go to college
D. have had computers in their bedrooms
B. Habits of TV watching reduce learning interest．
C. TV watching leads to lower education levels of the 15-year-olds．
D. The connection between TV and education levels is difficult to explain．
B. Children should be forbidden from watching TV.
C. TV sets shouldn"t be allowed in children"s bedrooms．
D. Further studies on high-achieving students should be done．
learning. One needs memory to ride a bicycle. A dog needs to remember if it is to come when called.
Memory is said to be stored in the brain as a "memory trace(记忆痕)." What makes up this trace
is not known. Some scientists believe that certain chemical substances may carry certain memories.
For example, one substance, when given to rats, causes them to fear the dark.
Other research into memory has to do with how the brain works. Psychologists use three means
to find out how a person remembers. For example, give a person a grocery list. Let the person
memorize the list, then put it away. The most natural way to find out how much a person remembers
of the grocery list is to ask what he or she remembers. This is called the method of recall. Another
method is called recognition. Give the person another grocery list. Ask him or her to choose items on
the first list from the items that are on only the second list. Often a person will be able to recognize
things that he or she cannot recall. A third method of finding how much a person remembers is called
relearning. Here the person is asked to read over the first list. The person will probably learn the list
the second time faster than he did the first time. The difference in the time it takes to relearn the list is
thought of as a measure of how much a person has remembered.
One way of remembering something is to repeat it many times. Interest is very important. Boring
lists of facts are much more difficult to remember than something that we understand and are interested
in. Motivation, or wanting to do something, is also important. Motivation is linked with reward. For
example, a hungry animal quickly learns how to do something if that action gets the animal food. In
humans, wanting to learn is often motivation. The praise of a teacher or the knowledge that an answer
is correct is rewarding.
B. it is hard to tell what a memory trace consists of
C. chemical substances carry certain memories
D. memory is stored in the brain as a substance
B. recall
C. memorization
D. relearning
B. The type of list items.
C. The time difference of relearning.
D. The time difference of brain working.
B. praise it in words
C. reward it with food
D. weaken its motivation
treat sticks as dolls, carrying them around until they have children of their own. Young males engage
in such behavior much less frequently.
The new work by Sonya M. Kahlenberg and Richard W. Wrangham, described this week in the
journal Current Biology, provides the first evidence of a wild nonhuman species playing with dolls, as
well as the first known sex difference in a wild animal"s choice of playthings.
The two researchers say their work adds to a growing body of evidence that human children are
probably born with their own ideas of how they want to behave, rather than simply mirroring other
girls who play with dolls and boys who play with trucks. Doll play among humans could have its
origins in object-carrying by earlier apes (猿类), they say, suggesting that toy selection is probably
not due entirely to socialization.
"In humans, there are obvious sex differences in children"s toy play, and these are remarkably
similar across cultures," says Kahlenberg. "While socialization by elders and peers has been the
primary explanation, our work suggests that biology may also have an important role to play in activity
preferences."
In 14 years of data on chimpanzee behavior at the Kibale National Park in Uganda, Kahlenberg
and Wrangham counted more than 100 examples of stickcarrying. Some young chimpanzees carried
sticks into the nest to sleep with them and on one occasion built a separate nest for the stick. "We
have seen juveniles occasionally carrying sticks for many years, and because they sometimes treated
them rather like dolls, we wanted to know if in general this behavior tended to represent something
like playing with dolls," says Wrangham, a Professor at Harvard. "If the doll hypothesis (假设)
was right, we thought that females should carry sticks more than males do, and that the chimpanzees
should stop carrying sticks when they had their first child. We have now watched enough young
chimpanzees to prove both points."
B. She treats them as dolls.
C. She makes useful tools from them.
D. She treats them as weapons.
B. Socialization.
C. Environment.
D. Cultural difference.
B. sex difference is the only factor in human"s choice of playthings
C. the biology factor may also influence toy choice
D. people choose different toys in different cultures
B. different factors cause humans and chimpanzees to choose different playthings
C. only female chimpanzees have playthings
D. chimpanzees usually choose playthings for their children
Doctors say anger can be an extremely damaging, unless you learn how to deal with it. They warn
that anger can lead to heart disease, stomach problems, headaches, emotional problems and possibly
cancer.Anger is a normal emotion that we all feel from time to time, some people express anger openly
in a calm reasonable way. Others burst with anger, and scream and yell. But other people keep their
anger inside. They can not or will not express it. This is called ______________.
For years many doctors thought that repressing anger was more dangerous to a person"s health than
expressing it. They said that when a person is angry, the brain release the same hormones(荷尔蒙). They
speed the heart rate, raise blood pressure, or sugar into the blood, etc. in general the person feels excited
and ready to act.
Some doctors say that both repressing and expressing anger can be dangerous. They believe that those who express anger violently may be likely to develop heart disease, and they believe that those who keep
their anger inside may face a greater danger of high blood pressure.
Doctors say the solution is learning how to deal with anger. They say the first step is to admit that you
are angry and to recognize the real cause of the anger, then decide if the cause is serious enough to get
angry about. If it is, they say, "Do not express your anger while angry. Wait until your anger has cooled
down and you are able to express yourself calmly and reasonably."
Doctors say that a good way to deal with anger is to find humor in the situation that has made you
angry. They said that laughter is much healthier than anger.

If you don"t express your anger, you may have more chances of having high blood pressure.

moment! She quickly picked up the wet phone and tried to turn it on, but nothing worked. Her first
reaction? She got dressed, drove to the nearest store, and bought a new model at full price.
A new study finds that fear of losing your phone is a common illness. About 66 percent of those
surveyed suffer from nomophobia or "no mobile phone phobia". Interestingly, more women worry
about losing their phone than men.
Fortunately, there"s a solution.
The first step is to figure out if you have nomophobia. Checking your phone too often is one
thing,but the true sign of a problem is that you can"t conduct business or go about your routine when
the fear becomes so severe.
Do you go to unusual lengths to make sure you have your phone? That"s another sign of a
problem.If you find you check your phone plenty of times per hour, or a total of an hour per day,
there may be a problem.
Some of the treatments are similar to those for treating anxiety attacks: Leaving the phone behind
and not checking e-mail or text messages, and then learning to tolerate the after anxiety. Even if this
leads to a high level of worry and stress, the solution is to push through the fear and learn to deal
with not having your phone.
Of course, there are also technological alternatives. Luis Levy, a co-founder at Novy PR, says
he uses an application called Cerberus that can automatically track the location of his phone. To
find it, he can just go to a Web site and see the phone"s location.
He also insures his phone through a service called Asurion. The company"s description of its
product reads like a prescription for anxiety: "60 million phones are lost, stolen or damaged each
year. You"ll have complete peace of mind knowing that your phone is protected and you can
quickly reconnect with family, friends and work, as soon as the very next day!"
B. To inform us that mobile phones are useful.
C. To warn us that we should be careful.
D. To tell us we should get phones ready for a trip.
B. Fear of losing mobile phones.
C. Eagerness for new mobile phones.
D. Independence of mobile phones.
B. Learning more about modern technology.
C. Protecting one"s phone against any damage.
D. Not using a mobile phone in one"s daily work.
B. It will give you a new phone through insurance.
C. It enables you to reconnect with your acquaintance.
D. It gives you a prescription to treat nomophobia.
B. New mobile phone technology.
C. Disadvantages of mobile phone.
D. Solutions to nomophobia
