All of us have felt pain, which can take complete control of our body and mind, making it impossible to move and even to think. Yet we need pain, without which we wouldn't know if we have hurt ourselves. It is our body's warning system, which tells us that we are injured and should do something about it.
Pain is the most common reason we go to a doctor or other healer. It is the most common reason we take medicine. Until recently, however, most doctors knew of only a few drugs that stopped some pains. They knew little about the process of pain itself, about which, however, new knowledge is helping them learn to control pain better.
Scientists have learned that the sense of pain is made up of both chemical and electrical signals, which travel from nerve cells (神經(jīng)細(xì)胞) in the injured area, up the central nervous system to the brain. And back down again. Scientists also have learned that the nervous system sends two different kinds of pain message to the brain, one very fast, and the other slow.
The first message is warning signal, which moves at a speed of 30 meters a second, and which travels to the middle part of the brain, and then to the outer part. In less than a second, the brain understands what part of our body is hurt and how badly it is injured. At a speed of only one meter a second moves the other message, which is the first step in the healing process, in which an important part is played by a very powerful material called prostaglandin, which are produced in almost every part of our body when needed. Scientists say prostaglandin raise and lower blood pressure, and also cause fever. When we hurt ourselves, the injured part produces a chemical that changes into prostaglandin, which cause the injured part to become red and swollen. and send the second, slower message of pain to the brain, which tells us not to use the injured part until it heals.

2.The English “________ ” in the passage can be translated into the Chinese “中樞神經(jīng)系統(tǒng)”.

3.Why does the brain know very well that we have hurt ourselves, and even what part of our body is hurt and even how it is injured, in less than a second? Because as soon as we hurt ourselves the warning signals will travel at once, at a speed of________ from nerve cells in the injured areas, up our central nervous systems to the middle and then to the outer part of our brains.
A. 180 kilometers an hour
B. 180 meters a minute
C. 108 kilometers an hour
D. 108 meters a minute
4.Which of the following is true according to this passage?
A. All doctors can take complete control of pain in different ways.
B. Pain can control our body and mind completely.
C. Prostaglandin, the most common drug, is known everywhere.

All parents have skyhigh hopes for their children.We want them to be confident and content.What can parents do to help their kids grow up to lead happy lives? Experts advise:
1.Helping them find their talents.In order to succeed,children need to feel they’re good at
something.So expose your children to as many interests as possible,then let them choose those they like best.
2.Applauding their achievements. A study found that students whose parents paid attention to
their abilities were far more likely to do well in school-and in life-than students whose parents didn’t show such support.So celebrate your kids’achievements,no matter how small they are.
3.Praising their efforts. Kids won’t always come out on top.Still,they deserve kudos (贊譽(yù)) for trying their best.Tenyearold April Cutler,for example,has had trouble with math since second grade.
"She usually gets C’s on her report card,but last year she was determined to get A’s and worked hard at it," says her mom.“When the first grading period ended,April was disappointed when she got a B
minus in math," Lueille continues.“But my husband and I told her we were very proud that she’d
improved.That inspired her to try even harder.She got a B plus for the next period !"
4.Letting them make decisions and mistakes.Making his/her own decisions increases a child’s
sense of control and builds his/her selfesteem (自尊心).And allowing kids to make wrong decisions-so
long as doing so won’t harm them-helps kids learn from their mistakes.
5.Encouraging them to solve their own problems.As they grow,children need practice in
communicating,standing up for themselves and compromising.One of the best places to learn these skills
is at home.So the next time your child runs to you complaining that her brother is blaming her,step back
and let them work it out.
1.What is the purpose of the passage?
A.To encourage parents to admire their kids.
B.To show how to praise kids.
C.To help kids study harder.
D.To give advice on how to help kids become mature.
2.The passage is mainly intended for________.
A.kids
B.parents
C.teachers
D.educators
3.From the example of April Cutler,we can learn that________.
A.praising kids’ efforts can help them make greater progress
B.setting a high goal makes kids feel discouraged
C.solving problems by themselves helps kids feel confident
D.interest is the best teacher
