Cellphones help us easily find people anywhere at any time. However,using cellphones too often may cause cancer. It's reported that people who used a cellphone for 10 years or more were more likely to get brain cancer. 

   The suggestions below may help you reduce the risk (風(fēng)險(xiǎn)) of cancer: 

   ◆When using your cellphone,try lo keep it away from your body as much as possible. Don’t put it under your pillow (枕頭) or on a bedside table when you go to sleep.

   ◆When you’re on the cellphone,use the speaker. In this way,you have just 1/100th of the contact (接觸) with radiation you have when you hold it to your ear. An earphone is also a good idea.

   ◆Try to keep your conversations short. If you need to talk longer,use an ordinary phone instead. 

   ◆Change ears when you’re using your cellphone. Before putting it to your ear,wait until the person you are calling picks up the phone.

   ◆Your phone gives out radiation when you talk or text (發(fā)短信) ，but not when you’re listening or getting messages. Listening more and talking less can lower the risk of cancer.

   ◆Do not use your cellphone when the signal (信號(hào)) weak or when moving at a high speed,for example in a car or train. At high speeds your phone is trying to pick up signals,and this increases the radiation it gives out.

   You probably talk to friends much more than you talk to your parents. That's natural. Even if you and your parents have a great relationship,you want to find your own path and make your own choices. Still,most of us want a parent's help,advice,and support at times. However talking to the adults in your life can seem difficult. But how to make it easier?

   First,talk about everyday stuff and do it every day. The more you do something,the easier it gets. Talking to the adults in your life about everyday stuff builds a bond that can smooth the way when you need to discuss something more serious.

   Find something unimportant to chat about each day. Talk about how your team did or share something one of your teachers said. Even small talk about what's for dinner can keep your relationship strong and comfortable.

   It's never too late to start. If you feel your relationship with your parents is nervous,try relaxing conversations. Talk about how well your little sister is doing in math. Chatting with parents every day keeps the relationship stronger.

  According to a new survey,student safety has become a big problem. Nearly 50% of students say they are worried about robbery (搶劫) on the way to and from school. Now in many big cities in China,some schools have taught an unusual lesson: self-protection (白我保護(hù)) . Students like this lesson because there are no exams or boring classes. And they can learn how to save lives and know how to stop danger before it really happens.

   Chen Haoyu,a teacher at Beijing No. 25 Middle School and a self-protection expert (專家) ，gives young students advice on how to deal with danger.

   Keep calm. If you can not cry for help or run away,give the robber your money. Try to remember what the robber looks like and tell the police later.

   If you are in a traffic accident 

   If a car hurts you,you should remember the car number;if it is a bicycle,try to call your parents before you let the rider go. This is because you don't know how badly you are hurt.

   Don’t stay in high places and keep away from trees.

   Get away as fast as you can. Put wet things on your body and try to find an exit (出口) . Do not take the lift!

  “Be proud of what you do,”my father often tells me ,“whether (無論是) you are a manager or a cleaner. ” At the age of 15 ,I got my first job—a summer job in a hospital. My work is to wash dishes and sweep the floors. I smiled and remembered Dad’ s words.

People in hospital all liked me. Every morning I always thought that the dirty dishes would make people ill without my job to wash them. After breakfast was done,I started sweeping the floors of all patients , (people who are ill) rooms and cleaning restrooms. I was very tired,but I wanted to do the job well.

   Many people like to travel by plane,but I don,like it because an airport is usually far from the city. You have to get there early and wait for hours for the plane to take off (起飛) and it is often late. You can't open the windows. You can’t choose the food. Planes are fast but it still takes much time to go out of the airport and into the city.

   I like traveling by train. I think trains are safe. Railway stations are usually in cities. When you are late for a train,you can catch another one. You can walk around in the train and open the windows . You can see many interesting things on your way. I know it takes a little more time.

   I also like cars. You can start your journey whenever you want to,and you don't need to get to a railway station or a bus stop. Also you can carry many things with you in a car. But sometimes there are too many cars on the road.(江蘇省蘇州市2012 —2013學(xué)年八年級(jí)期中模擬考試英語(yǔ)試題)
