Cell phones help us easily find people anywhere at any time. A cell phone can include many things, such as games, music and internet access. Today, 4.6 billion people around the world have cell phones, according to CBS news.
However, cell phones may cause cancer, according to the World Health Organization. In a 2010 study, people who used a cell phone for 10 years or more were more than two times as likely to get brain cancer, according to CNN.
These suggestions may help you reduce your risk of cancer:
1.Use a headset or speaker
Headsets give out much less radiation than phones. Some wireless headsets give out low-level radiation. However, you should take it off your ear when you’re not talking to anyone. Using your phone with a speaker will also make it safer.
2.Listen more, talk less
Your phone gives out radiation when you talk or text, but not when you’re listening or getting messages. Listening more and talking less can lower the risk of cancer.
3.Hold the phone away from your body
Hold the phone away from your body when you’re talking, not against your ear. Also, don’t keep it in your pocket.
4.Choose texting over talking
Phones emit less radiation to send texts than to carry a person’s voice. Texting also keeps radiation away from your head.
5.Poor signal? Stay off the phone
Fewer signal bars on your phone mean that the phone needs to give out more radiation to work. Make and take calls when your phone has a strong signal.From the first paragraph, we know that ____________.

I have been a friend of Bill Gates for a long time. I knew him when he was a student at Harvard University. We were surprised when he left University to set up his own company “Microsoft” and make his own software. But he was the clever one! He is very good at writing computer languages and almost all computers now use Microsoft software. The program “Word” is used from Britain to China!
Of course he has made a lot of money and that makes people very jealous. They want to stop his success. Even the government is against him and has tried to break his company into two parts. The government says that it is unfair to other people who want to sell similar software. And what's more, because he fits his new software free in every new computer, the government says he is stopping other companies from selling their programs. This is not fair. Everyone should be able to do what they can to make their company bigger and stronger. Bill Gates has only done what he can to stop other competitors.
He is very rich, but he is generous. He has given millions of dollars to help the education and health of many children around the world. You could not meet a better man than Bill Gates.将文中画线句子翻译成汉语。

Only a few years ago, mobile phones were very large. They needed large batteries. They had to be powerful to send their signal to faraway places. This was because most cities had only one antenna tower(中继站) for mobile phones.
Today’s mobile phones are small and easy to use. Now most cities have a lot of antenna towers, not just one. This means that each mobile phone doesn’t have to send its signal far away, so they don’t need to be so powerful. Mobile phones today use small batteries. A large city, where lots of mobile phones are used, can have hundreds of towers.
We can use a mobile phone to do a lot of things, like calling your friends and family from almost anywhere, calling the police immediately if there is an accident, sending or receiving messages. Some modern mobile phones can be even used to play games, take photos, listen to music, watch TV, surf on the Internet and so on.
Sending short written messages is a popular way to use your mobile phone. Many people use short forms of words, so the messages are quick to write and read. Can you guess what these messages mean? RUOK? CUL8r! That’s EZ! That’s Gr8! Can I C U B4 3pm 2moro? Try to read them out. What do you hear?

When we travel from one country to another, we find people have quite different feelings about food. People often feel what they eat is normal, and what other people eat is strange or silly. In most part of Asia, for example, people like rice and meat. In England, people eat potatoes every day. In the Middle East, bread is the main part of every meal. Eating, like so many things we do, becomes a habit which is difficult to change. Americans like to drink a lot of orange juice and coffee. The English drink tea four or five times every day. Australians drink a great deal of beer, and the French drink wine every day.
The sort of meat people like to eat is also different from one country to another. Horse meat is thought to be delicious in France. In Hong Kong, some people enjoy eating snakes. New Zealanders eat sheep, but they never eat goat meat. The Japanese don’t like to eat sheep meat because of its smell, but they enjoy eating uncooked fish.
