Earthquakes happen without warning(前兆). They can happen any time of a day, at any point during the year. When an earthquake is happening, you should know what you should do or not do.
Do NOT go outside. You could get injured from falling glass or parts of buildings. If you are outside, stay away from buildings and power lines(输电线).
Stay under a desk, table, or other strong furniture. Hold on to it. Or stay in a corner of the building. Cover your face and head with your arms and cover your mouth with a towel or clothing. Stay inside until shaking stops and it is safe to go outside.
Keep away from windows, pictures or advertisements on the wall or the building, and anything else that could fall and hurt you. Most people get injured by falling things during an earthquake, not by the shaking itself.
Also keep away from a fire. You could fall down and burn yourself on the fire.
If you are driving when an earthquake happens，stop the car if it’s safe. Stay inside your car until the earthquake stops, and don’t drive near bridges. Try not to stop by power lines or trees. These could fall and hurt you.

Every object has weight. But the center of its weight is not always in the middle of the object. If the top of an object is heavier than its bottom, it will fall over easily. We say that its center of gravity is high. But if the bottom is heavier, it won’t fall easily. Then we say that its center of gravity is low.
Look at the first picture. This empty box must fall over, because its center of gravity (C) is not above the line of its bottom (AB).
Now look at the second picture. There is some heavy iron in the bottom of this box. It will not fall, because its center of gravity is above its bottom.
小题1:If the bottom of an object is ______ its top, it will fall over easily.| A．lighter than | B．heavier than | C．no heavier than | D．as heavy as |
小题2:Please point out which box will not fall.
小题3:The main idea of the passage is _________.| A．why things fall over | B．a low center of gravity | | C．a high center of gravity | D．that everything has weight |

Hu Yaohui, a schoolgirl in Zhejiang province, didn’t want to speak or eat for a week. She kept worrying about her scores on the exam. “I can’t stop thinking about my place in the class,” she said. “I feel stressed out.”
Hu is not the only one who faces stress. According to a recent survey conducted by Wuhan University of Hubei province, 70 percent of the 2,000 students who are going to take the college and high school entrance exams feel under pressure (压力).
Stress is a normal physical response (反应) to things that make people feel worried or break their balance of life in some way.
Stress isn’t always bad. Sometimes, people’s stress is important during emergency situations, such as when a driver has to stop his car to avoid an accident. Sometimes, stress can help people do their best — like while getting ready before a big competition or exam.
However, too much or long-term stress gives people a stress overload (负荷过多). People with stress overloads may have problems remembering or concentrating on things. They are quick to get angry or lose patience. They may even have other problems, such as sleeping problems, headaches and often getting colds.
The most helpful way to deal with stress overloads is to learn how to manage the stress. For example, you might manage it by getting a good night’s sleep, or by exercising every day.
Another good way to deal with stress is to ask parents or friends for help. Everyone has stress. For many people, stress is so common that it has become a way of life. Don’t be too shy to tell others that you are having a hard time. They may comfort you or give you some useful advice. Sometimes just sharing your problems with someone else can make you feel better.
小题1:Hu Yaohui felt stressed out about ________.| A．her marks on the exams | | B．which seat to take during exams | | C．not being able to sit in the front | | D．not being allowed to eat in class |
小题2:According to the survey in Paragraph 2, _______ of the 2,000 students who will take entrance exams feel stressed.| A．nearly half | B．about 1,400 | | C．almost seven hundred | D．about one seventh |
小题3:Which of the following is TRUE?| A．Stress is a kind of serious heart disease. | | B．Stress is always bad for people. | | C．Stress is always useless for an exam. | | D．Stress is greatly needed sometimes. |
小题4:This passage is mainly about “________”. | A．Many students face stress now. | | B．People’s stress is always important. | | C．How to get less stress | | D．How to get good results with the help of stress. |

IQ（intelligence quotient智商）is a score that shows a person’s level of intelligence.
People used to believe that some people are born with a high IQ and some aren’t.
32 , a study by scientist at University College London has challenged（挑战）this idea. According to an article last October on the Journal Nature, scientists are beginning to think that our IQ is not a constant（不变的）score.
The scientists tested 33 healthy young people in 2004 between the ages of 12 and 16. Then they did tests again four years later, when the same people were between 16 and 20.
Scientists found big changes in the IQ scores between 2008 and 2004. Some 33 and some fell 34 as many as 21 points.
To test whether these scores were meaningful, the scientists compared them with results from brain scans（扫描）. They found that the IQ changes matched changes in the structure（结构）of the subjects’ brains. “A change in 20 points is a huge 35 ,” said Professor Cathy Price, who led the research. He said it could mean the difference between an average and a 36 person. The team has not found a clear cause for these changes. However, they say it is 37 that education plays a role in changing IQ.
“Here we have shown that children’s 38 is likely to be still developing, ” says Price. “We have to be careful not to write off 39 performers at an early stage. In fact, their IQ may improve in a few more years. ”

Many people catch a cold in the spring time and / or fall. It makes us wonder .if scientists can send a man to the moon, why they can"t find a cure for the common cold. The answer is easy. There are exactly hundreds of kinds of cold viruses there. You never know which one you will get, so there isn"t a cure for each one.
When a virus attacks your body, the body works hard to get rid of it. Blood rushes to your nose and brings congestion(充血)with it .You feel terrible because you can"t breathe well, but your body is actually "eating" the virus. Your temperature rises and you get a fever, but the heat of your body is killing the virus. You also have a running nose to stop the virus from getting to your cells. You may feel miserable, but actually your wonderful body is doing everything it can to kill the cold.
Different people have different remedies（治疗法）for colds. In the United States and sane other countries, for example, people might eat chicken soup to feel better. Some people take hot baths and drink warm liquids. Other people take medicine to stop the fever, congestion, and running nose.
There is one interesting thing to note - some scientists say taking medicines when you have a cold is actually bad for you. The virus stays in you longer because your body doesn"t have a way to fight it and kill it .Bodies can do an amazing job on their own. There is a joke, however, on taking medicine when you have a cold. It goes like this:
If it takes about one week to get over a cold if you don"t take medicine, but seven days to get over a cold you take medicine.
