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 (风险) 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 (枕头) 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 (接触) 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 (发短信) ，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 (信号) 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.

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 (起飞) 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.(江苏省苏州市2012 —2013学年八年级期中模拟考试英语试题)
