WARNING(警告): Holding a cell phone against your ear or putting it in your pocket may be bad for your health. This sentence is a warning that you'd better not put it close to you when a new phone is bought. Apple company, for example, doesn't want iPhones to come closer to you than 1.5 centimeters; Research In Motion, BlackBerry's producer, recommends 2.5 centimeters.

      If cell phone use can cause health problems, the result will be very serious. Americans spend 2.26 trillion minutes chatting on cell phones every year, which brings $109 billion for the wireless businessmen.

      Devra Davis, an epidemiologist(皮肤病专家)who has worked for the University of Pittsburgh, has published a book about mobile phone radiation(辐射)"Disconnect." Davis studies how often brain cancer happens during different age groups. As a result of mobile phone radiation, she finds that a big increase(增长)in brain cancer in the 20-to-29 age group and a drop for the older people.

      Children are more easily hurt by radiation than grown-ups, Ms. Davis and other scientists point out. But no studies have yet been finished on cell phone radiation and children, she says.

      Henry Lai, a research professor, began lab radiation studies in 1980 and found that mice exposed to(暴露在) radiofrequency（电波频率）radiation had destroyed DNA in their brains.

      Ms. Davis recommends using wired earphones（有线耳机）or the phone's speaker. Children should send text messages rather than call, she said, and pregnant women should keep phones away from their bodies.

    What is a hurricane?

    You may already know that hurricanes are storms that can cause devastating (毁灭性的) waves, wind, and rain. They happen during “Hurricane Season,” which is from June 1st until November 30th in the Atlantic Ocean and from May 15th until November 30th in the Pacific Ocean.

    Types of Hurricanes

    There are five types of hurricanes, which are based on wind speeds. The categories help people know how much damage a hurricane may cause because the greater the wind speed, the more dangerous the storm. For example, a Category 5 hurricane has winds over 155 miles per hour, which are strong enough to destroy the buildings along the shorelines completely.

    Hurricane Dangers

    When a hurricane happens together with heavy rainfall, there can be a devastating flood. The centre of a hurricane is called the eye. While most of a hurricane has dangerously strong winds, the eye is actually a calm area in the storm. When the eye of a hurricane passes over land, people might think that it's over, but before long the wind and rain increase again as the second part of the hurricane moves through.

    Hurricane Safety Tips

    There is no way to stop a hurricane or make it change direction, so if you ever find yourself in the path of a hurricane, be sure to remember the following safety tips.

    Be sure you have a radio, batteries, fresh drinking water, and enough food.

    Tell neighbours, friends, and family members your emergency plans. Tell them where you'll go if you need to leave your home.

    If you live near the ocean, leave your home and travel to a safe place. You could stay with a friend or a family member, in a hotel／motel, or in an emergency shelter area.

    Stay inside during the storm. You could be seriously injured if you go outside.

    A Greeting is a way of saying "Hello" to．someone．People in different countries greet each other in different ways．The following are some examples．

    In the United State，people usually shake hands．The handshake has an interesting origin(起源)．It started long ago as a way of showing people that they weren't carrying a weapon(武器)．Shaking the person's right hand while looking him or her in the eye is the usual way．

    Handshakes are also common in other parts of the world，including Britain and Russia．In Russia, a man often holds another man's hand very strongly during the handshake．Most people in New Zealand also greet each other by shaking hands．However，the Maori people in New Zealand greet each other by pressing their noses together．

    In other countries，such as France and Belgium，hugging and kissing are more common when two people meet. In those cultures，people kiss each other on the cheek(面额)．The number of kisses is different from country to country．In Saudi Arabia，men might hug and kiss each other(but not with a woman)on the check．In some Eastern countries，including Japan，bowing is the traditional way of greeting people．

Hi, David,

    Guess what? I'm writing to you from Beijing! It's my first summer holiday abroad, and here I'm in China! I'm going to learn Chinese for two weeks at a summer camp. Then my parents are going to join me here. I plan to spend another two weeks here and go on a tour around the country with them. It's going to be very exciting! We're going to visit the Great Wall and the Palace Museum in Beijing. Then we're going to be in Xi'an from July 24th to 27th. My dad says he's going to take lots of photos of the Terracotta Warriors. After that, we're going to Jiuzhaigou. It's famous for its beautiful mountains and clear lakes. Our last stop on the trip is Sanya. My mum's going to spend lots of time on the beach, but I'm going to swim in the sea every day.

    OK, I have to go. I'm going to meet my Chinese penfriend, Daming. He's going to take me to the Bird's Nest tonight. There's going to be a rock concert there. I can't wait!

Yours,

David
