How important is your mobile phone, better known to Americans as a cellphone? Jack said, “I use my phone all the time. I’m always on my phone.” Ann said, “It’s important to me because it’s like my life saver.” Jenny said, “I need my cellphone. I cannot live without it.”

So far, no studies have proven beyond question that the radio signals from cellphones cause brain cancer or other health problems. But a new study by government scientists in the United States has some people wondering what to think. The scientists have found that holding a cellphone to your ear for more than fifty minutes increases brain cell activity. Even the scientists themselves are not sure about the meaning of their findings.

Dr Nora Volkow led the study. She heads the National Institute on Drug Abuse, part of the National Institutes of Health. Dr Volkow says she is not concerned that fifty minutes of cellphone exposure (暴露) would harm anyone. But she says the research does show the need to study whether there are long-lasting effects of repeated exposure over several years.

Her team studied forty-seven healthy volunteers between January and December of 2009. The volunteers had cellphones placed against both ears while the scientists made images of their brain activity. As part of the test, one phone was activated (使激活)for fifty minutes. The other phone was off. After that, the volunteers were tested with both phones turned off. Dr Volkow says the brain scans(扫描) showed increased activity in brain cells closest to the activated phone.

The scans showed how the brain cells used sugar to produce energy, a normal activity. The activity was seven percent higher in areas of the brain closest to the cellphone antenna(天线).

Dr Giuseppe Esposito is a nuclear medicine expert at Georgetown University Medical Center in Washington. He says after many years of studies, better kinds of research are still needed to settle questions about cellphone safety. These studies would take years.

As an English speaker, you must know a lot of English words. You can read, speak and understand. But there is another kind of language you have to know — the language of the body, a part of what is called non-verbal communication. All over the world, people “talk” with their eyes. When Chinese people meet, they usually shake their hands. What do American and British do?

Americans are more informal than the British. They like to be friendly. They use first name, they ask questions and they talk easily about themselves. When they sit down, they like to relax in their chairs and make themselves comfortable.

British people are more quiet. They take more time to make friends. They like to know you before they ask you home. ?

When British and American people meet someone for the first time, they shake hands. They do not usually shake hands with people they know well. Women sometimes kiss their women friends, and men kiss women friends (on one cheek only). When a man meets a man friend, he just smiles, and says “Hello”. Men do not kiss each other. Even fathers and sons do not often kiss each other.
