题目内容

If you see someone drowning, speed is very important. Once you get him out of the water, if he isn’t breathing, you have four minutes before his brain is completely destroyed. Support his neck, lift his head back and press his chin upwards. This stops the tongue blocking the airway in the throat and is sometimes enough to get him breathing again. If that doesn’t work, start mouth-to-mouth breathing. Press his nostrils (鼻孔)together with your fingers .Open you mouth and take a deep breath. Blow into his lungs until his chest rises, then remove your mouth ,and watch his chest fall. Repeat twelve times a minute. Keep doing until help arrives.

To bring a child back to life, keep your lips around his mouth and nose and gently blow into his mouth. Give the first four breaths as quickly as possible to fill the blood with oxygen. If , in spite of your efforts, he starts turning a blue-grey color, you can feel no pulse(脉搏). Then pressing is the last chance of saving his life.

With arms straight, rock forwards, pressing down on the lower half of the breastbone. Don’t be too hard or you may break a rib (肋骨). Check how effective you are by seeing if his color improves or his pulse becomes independent to your chest pressing. If this happens, stop the pressing. Otherwise continue until rescue arrives.

Dust storms are violent and mostly unpredictable. They can cause property damage, injuries, and deaths, so it’s necessary to know what to do when you come across them.

Watch out for dust storm warnings. Dust storms are most likely to occur on hot summer days, so listen to the local TV or radio broadcasts before traveling in hot, dry conditions, and consider changing or giving up your trip if dust storms are predicted. Roadside signs may also be able to warn you of dust storm danger.

Be prepared. If you are in a storm-prone area, carry a mask(口罩) to keep out small dust particles (颗粒), and take eye protection to protect your eyes. A supply of water is also necessary.

Go beyond the storm. If you see a dust storm from some distance, and you are in a vehicle, you should try to escape from it. Some dust storms can travel at more than 75 miles per hour, but they frequently travel much slower. However, it is not advisable to put yourself at risk by driving at high speed.

Stay inside. Do not move about in a storm, as you will not be able to see hidden risks in your path. So if you’re in a house, stay inside.

Protect yourself from flying objects. Cover as much of your body as possible. A dust storm’s high wind can carry heavy objects. If you find yourself without shelter, try to stay low, close to the ground, and protect your head with your arms, a backpack or a pillow.

1.What does the underlined sentence in Paragraph 4 mean?

A．Dust storms usually travel much slower than vehicles. B．Don’t be so worried about dust storms in the distance. C．You shouldn’t drive at a risky speed to escape from dust storms. D．Driving faster than the dust storm is the most important thing.

2.We can learn from the passage that __________

A．it is dangerous to travel on hot summer days B．dust storms usually come from far away C．people should stay indoors when a dust storm comes D．small objects blown by a storm’s wind cannot harm people

3.Which of the following may NOT really be needed when you come across a storm?

A．A pair of glasses. B．A blanket. C．A bottle of milk. D．A travel guide.

4.A weatherman may give you all of the following advice EXCEPT that "_____________".

A．do not enter a dust storm B．mind the warnings on the roadside signs C．close all the doors and windows of your house D．cover your body with as many things as possible

Recently a group of children in America poured some gasoline on a sleeping man and set him on fire. When caught, the children said they had done what they’d seen on TV.

The incidents make people angry who believe that American children are harmed by watching too much TV. They claim children can’t tell between the fiction of TV and reality, and TV distracts them from learning and makes them violent.

To estimate the impact of TV on young people, “Life” magazine hires a company to interview hundreds of school children in Nora Springs, Iowa and in Dallas, Texas. Although the two cities are very different, the company finds children in each city watch the same TV shows.

Many Iowa children, who watch an average of three hours of TV a day, recognizing that life on TV is rosier than what they experience. Their favourite shows are situation comedies about American families in trouble. Many boys like violent shows about police detectives or heroes, girls particularly soap operas-stories about families and friends.

On the whole, children find real violence on news programs hard to take. “If you see a bus crash on the news, it’s frightening,” one fifth grader says. By and large, the Iowa children agree that the best thing about TV is it makes you laugh.

Children in Dallas are savvier about programs of drug use on TV. “They don’t really show them doing it right. On TV they are not real.” A fifth grader says.

“Life” agrees with a 1988 study by the U. S Department of education that finds children are none the worse for watching TV. The study finds TV doesn’t have lasting effect on children. On the contrary, kids show good judgment about what they watch. “There are very few good shows on TV anymore,” a 10-year-old boy says.

While the debate about TV is so heated, the “Life” survey gives hope that American kids aren’t wasting three or four hours a day (what is worse, by the time young people enter college today, they will have devoted more time to watching television than they will spend in college). However, a child watching TV isn’t reading a good book or joining in healthful sports.

1.The main idea of the passage is .

A．children who watch more TV are smarter than those who watch only one hour a day

B．children learn about drugs from watching TV

C．watching too much TV can cause children to go out and kill people

D．children learn from TV and can tell reality from what they see on it

2.Children who see real violence on TV news programs .

A．change the channel to watch other programs	B．live in Iowa or Texas
C．are sometimes upset and scared	D．think TV gives a very positive image of friendship

3.Children who enter college today .

A．usually cause the satisfaction of the society

B．think life on TV is happier than their life at home

C．have spent more time watching TV than they will spend in college

D．watch most the same TV shows as children in Dallas

4.The “Life” survey of children’s TV habits .

A．concludes that watching up to seven hours a day of TV is good for children

B．agrees with the U.S. Department of Education study that finds few negative effects from watching TV

C．concludes that there aren’t any good shows on TV any more

D．concludes that children shouldn’t pour gasoline on sleeping man
