Keep Safe on the Road
Many people are not careful when crossing the road. As we can see in the picture, a car is running while a group of people are crossing the road even if the red light is still on. Running the red light is dangerous and it may cause accidents. How can we keep safe on the road?
First, we should obey the traffic rules and not cross the road until the “walk” sign turns green. Second, stop and look both ways before crossing the road. Third, walk along the sidewalks.
In a word, everyone should value his/her life. We should be very careful while crossing the road.

There are many things that you should be careful with when you are alone at home. Read the following tips to protect yourself.
●Keep the door locked when you are alone at home. Many people think it's the best way to protect themselves.
●Keep a list of phone numbers to call for help—such as 110, the police station or a neighbour's number.
●Be careful with the electrical appliances. If you don't know how to use them, ask your parents. Make a safety check before going to sleep.
●Look through the peephole when you hear the doorbell. If there are strangers, ask “Who's that？” with the door locked and say “Come back later.” Don't tell them that your parents are away. Say “Mum's having a shower.” or “Dad's sleeping.” To ignore (忽视) the doorbell is not a good idea because sometimes bad people ring doorbells to see if anyone is at home.

Mobile phones and the Internet have improved our life in many ways. However, along with improvements, they have also brought a number of worrying problems.
Many car accidents are caused by mobile phones. You can use many new mobile phones to get on the Internet. This can be very convenient, but some drivers get on the Internet while driving. Driving needs all our attention. By looking at their mobile phones and not at the road, these insensitive drivers are dangers to us all.
Many of the dangers of the Internet are well known. Children who visit websites without their parents' permission sometimes talk to older people they don't know and put themselves in great danger. People with blogs sometimes post embarrassing photographs of people they don't know on their websites without permission. There are also people who use the Internet to get personal information that we do not want them to have.
Mobile Phone and Internet Safety Tips
◇If you need to use a mobile phone while you are driving, use a “hands-free” phone.
◇In difficult driving situations such as rain or snow, do not use your phone at all.
◇Do not make very important phone calls while driving. They take your attention off the road.
◇Tell your children not to talk with anyone they do not know on the Internet.
◇In an embarrassing situation, pay attention to people around you. People will be shy about taking your pictures if they know you're paying attention.
◇Refuse to give out any personal information on the Internet.

B
The building is shaking. A woman with a baby in her arms is trying to open the door, but fails. Finding no way, she rushes into her bedroom and there they survive the earthquake.
In a factory building, as the workshop floor swings under the terrible shaking, workers run for safety. Some hide under the machines and survive, but others who try to run outside are killed by the falling ceilings.
These scenes, played by actors and actresses, are from a film of science education Making a Split Second Decision shown in 1998 on China Central TV in memory of Tangshan Earthquake.
By studying actual cases in the earthquake areas and scientific experiments, experts(专家) find that buildings remain untouched for the first 12 seconds of an earthquake.
In this short time, one has the best chance of surviving an earthquake by staying near the inside walls, in bedrooms and under beds, experts concluded in the film. “Earthquakes seem to catch the lives of those who run，” said many survivors in the earthquake areas, describing how their friends were killed in the doorways or along the stair steps as they tried to get out of the building.
Their advice was proved in the film, “Take a hiding-place where you are rather than running, unless you are sure you can reach a safe open place in ten seconds.”
( )25.The underlined word “survive” appears in the passage several times. It probably means “________” in Chinese.
A．遇难 B．幸存
C．恐慌 D．摇晃
( )26.The workers who tried to run outside the building died because________.
A．the factory building was shaking terribly
B．they were making a film
C．they didn't have enough time to run outside
D．they were too nervous
( )27.The passage suggests that you should ________ when an earthquake happens.
A．cry for help
B．not move but lie on the floor at once
C．run down the steps as fast as you can
D．find a safe place and hide in at once or run out in ten seconds
( )28.Where can we probably find this passage?
A．In a magazine.
B．In an advertisement.
C．In a history book.
D．In a poster.

One afternoon after school, Peter and Jane were walking along the street. Suddenly they heard a noise. “Come on！” shouted Peter. “That sounds like an accident. Let's see what happened.” They ran to the site where the noise came from.
As they got there, they could see what had happened. A small car had knocked into a truck. The accident happened in a quiet street with only four houses in it. Peter and Jane were the first ones to reach the accident. No other people came. “We must be the only ones who saw the accident，” said Jane. They found that both the car driver and the truck driver were hurt. “Peter，” said Jane, “run back down the street to Mrs. Day's house. Ask her to call the police and the ambulance. Hurry! I'll stay here.” Peter went off as fast as he could. There was nothing Jane could do but wait. She knew that when people were hurt in an accident, they shouldn't be moved. It__wasn't__long__before__the__police__car__and__the__ambulance__arrived. The policemen got the car door open and carried the car driver out. Then they got the truck driver out.

Thank you for all your help.”
