Only about 30 percent of people in the US know how to perform CPR (心肺复苏术). Recently, a 9-year-old boy showed a Georgia woman how to perform CPR on her newborn baby.
Susanna Rohm said she had experienced a parent’s worst nightmare (噩梦) — her 2-month-old son, Isiah, was not breathing. “I noticed he looked pale. I looked at his arms and his legs and they were limp (无力的),” Rohm told a local newspaper. “Then I noticed that he looked like he wasn’t alive.” Indismay, she dropped and broke her cellphone. Rohm had to run into the street, screaming for help.
“I had him in my arms and screamed over and over. Then I ran outside. I saw two boys playing across the street, and I yelled, ‘Go and ask your parents to call 911,’” Rohm said. But the two boys were able to do more than that. Nine-year-old Ethan Wilson took action, showing Rohm how to perform CPR on little Isiah while ten-year-old Rocky Hurt helped as well.
Rocky said he had learned the CPR technique from a poster in a health class at their school, Sedalia Park Elementary. “I was thinking we’d better give her a helping hand instead of getting scared,” Ethan said. “I told her to push on the baby’s chest five to ten times a minute with only two fingers, tilt back the baby’s head, plug the baby’s nose and breathe into the baby’s mouth,” Ethan said in an interview.
At last, Isiah began crying and was breathing again. He spent two nights in a local hospital. “If the little boy hadn’t shown me what to do right there, my baby would probably not be alive right now,” Rohm said.

A.CPR is considered important by most people
B.most children are taught how to perform CPR
C.many parents don’t know how to perform CPR
D.kids must learn how to perform CPR on babies
2.What does the underlined word “dismay” in Paragraph 2 probably mean?
A.Panic. B.Anger.

In the United States, 30 percent of the people have a “weight problem”. To many people the cause is obvious (明显的): they eat too much. But scientific evidence (证据) does little to support this idea. Going back to America of 1910, we find that people were thinner than today, yet they ate more food. In those days people worked harder physically, walked more, used machines much less, and didn’t watch television.
Several modern studies, moreover, have shown that fatter people don’t eat more on average than thinner people. A 1979 study of 3,545 London office workers showed that fat people eat less than slim (苗条的) people.
Studies also show that slim people are more active than fat people. A study by a research group at Stanford University found the following interesting facts:
The more the man ran, the greater loss of the body fat.
The more they ran, the greater increase in food intake.
Thus, those who ran the most ate the most, yet lost the greatest amount of body fat.
1.Nowadays many Americans have the problem that ______.
A. they are too slim B. they work too hard
C. they are too fat D. they lose too much body fat
2.According to the passage, how many people in 900 Americans have a “weight problem”?
A. 150. B. 300. C. 600. D. 270.
3.Is there any scientific evidence to support the idea that eating too much is the cause of a “weight problem”?
A. Yes, there is plenty of evidence.
B. Of course, there is some evidence to support this.
C. There is hardly any scientific evidence to support this.
D. We are not sure.
4.The Americans in 1910 ________.
A. ate more food and had more physical activities
B. ate less food but had more physical activities
C. ate less food and had less physical activities
D. had more problems

We are all busy talking about and using the Internet, but how many of us know the history of the Internet?
Many people are surprised when they find that the Internet was set up in the 1960s. At that time, computers were large and expensive. Computer networks didn’t work well. If one computer in the network broke down, then the whole network stopped. So a new network system had to be set up. It should be good enough to be used by many different computers. If part of the network was not working, information could be sent through another part. In this way, computer network system would keep on working all the time.
At first the Internet was only used by the government, but in the early 1970s, universities, hospitals and banks were allowed to use it, too. However, computers were still very expensive and the Internet was difficult to use. By the start of the 1990s, computers had become cheaper and easier to use. Scientists had also developed software that made “surfing” the Internet more convenient.
Today it is easy to get on-line and it is said that millions of people use the Internet every day. Sending e-mail is more and more popular among students.
The Internet has now become one of the most important parts of people’s life.

Many people think of the brain as a mystery. They don't know much about intelligence and how it works. When they do think about what intelligence is, many people believe that a person is born smart, average, or dumb — and stays that way in the whole life. But new research shows that the brain is more like a muscle — it changes and gets stronger when you use it. And scientists have been able to show just how the brain grows and gets stronger when you learn.
Everyone knows that when you lift weights, your muscles get bigger and you get stronger. A person who can't lift 20 pounds when he/she starts exercising can get strong enough to lift 100 pounds after working out for a long time. That's because the muscles become larger and stronger with exercise. And when you stop exercising, the muscles shrink and you get weaker. That's why people say “Use it or lose it!”
But most people don't know that when they practice and learn new things, parts of their brain change and get larger a lot like muscles do when they exercise. Inside the cortex (皮层) of the brain are billions of tiny nerve cells, called neurons. The nerve cells have branches connecting them to other cells in a complicated network. Communication between these brain cells is what allows us to think and solve problems. When you learn new things, these tiny connections in the brain actually multiply and get stronger. The more you challenge your mind to learn, the more your brain cells grow. Then, things that you once found very hard or even impossible to do — like speaking a foreign language or doing algebra (代数) — seem to become easy after learning them for a period of time. The result is a stronger, smarter brain.
Scientists started thinking that the human brain could develop and change when they studied animals' brains. They found out that animals that lived in a challenging environment were more “perspicacious” — they were better at solving problems and learning new things.
1.According to the first paragraph,________.
A. the function of our brain is like that of the muscle
B. until now it's impossible to explain the brain's mystery
C. many people believe one's intelligence is naturally determined
D. one's brain grows stronger as the age increases
2.Training muscles is compared to ________.
A. using the brain
B. connecting things in your brain
C. lifting weights
D. doing research about the brain
3.What is Paragraph 3 mainly about_________?
The complex structure of the brain.
B. How changes in the muscles affect the brain.
C. The importance of the brain.
D. How the brain becomes stronger by learning new things.
4.What does the underlined word “perspicacious” in the last paragraph probably mean_________?
A. Strong. B. Smart. C. Popular. D. Active.
5.The paragraph that follows the passage will most probably talk about _______.
A. the differences between animals’ brains and humans’ brains
B. the relation between human brains and muscles
C. scientists’ findings about animals’ brains
D. how to make your brain smarter through self-development

Until recently, scientists had mapped only about 20 percent of the sea floor. But our knowledge of the deep seas is changing because of information from satellites. Scientists have produced a new map that provides a detailed picture of the oceans. The map is expected to help oceanographers (海洋学家), industry and governments.
The new map is twice as detailed as the map made 20 years ago. David Sandwell is a geophysics professor at the University of California. He and other scientists worked on the mapping project. He says they turned to space to look deeper into the ocean.
The scientists collected and studied information from two satellites. Some of the data came from the European Space Agency’s Cryo-2 satellite. It was placed in Earth's orbit to watch sea ice. The other satellite is the American space agency's Jason-1. It is studying the surface of the oceans. Scientists combined the satellite data with images gathered by sonar (声波定位仪) equipment on ships. Sonar works by sending sound waves through the water. When the sound waves hit an object, its presence is confirmed.
The new map shows the sea floor as it has never been seen before. It shows thousands of underwater mountains and places where continents pulled apart. It shows where earthquakes were active many years ago. They all are buried deep underneath the ocean floor.
David Sandwell says the map is a powerful tool for fisheries, those interested in protecting the environment and for oil exploration.
“The petrol exploration industry is interested in how to reconnect the continents, bring them back together tectonically so you can map the basins (盆地)on one continental edge—say, Africa—and use that to establish where the similar basin would be on the other continental edge in South America.”
If scientists know that information, they may be able to find oil fields. The new data also will help scientists improve their estimates of ocean depths. This information can help ships travel safely and improve military operations and scientific projects worldwide.
Mr. Sandwell thinks scientists will make many more discoveries as they examine the new map and the information it provides.
1.Which one is not mentioned about the benefits brought by the new map?
A. Fisheries. B. Scientific projects.
C. Ship manufacture. D. Oil exploration.
2.What can we know about the new map?
A. It shows where earthquakes will happen.
B. It will be helpful to industry and governments.
C. It is three times as detailed as the old one years ago.
D. It is based on the data gathered by the spaceships.
3.The text is likely to appear in _________.
A. a sicence fiction B. an advertisement
C. a science magazine D. a finance report
4.Which of the following can be the best title for the text?
A. The detailed picture of the oceans
B. Underwater mountains and places
C. More discoveries about the oceans
D. Scientists create new maps of ocean floor
