Could your cellphone give you cancer? Whether it could or not, some people are worrying about the possibility that phones, power lines and wi-fi could be responsible for a range of illnesses, from rashes to brain tumors.

Some say there is evidence to support the growing anxieties. David Carpenter, a professor of environmental health sciences at the university at Albany, in New York, thinks there’s a greater than 95 percent chance that power lines can cause childhood leukemia (白血病). Also there’s a greater than 90 percent chance that cellphones can cause brain tumors. “It’s apparent now that there’s a real risk,” said Carpenter.

But others believe these concerns are unjustified. Dr Martha Linet, the head of radiation epidemiology(流行病学) at the US National Cancer Institute, has looked at the same research as Carpenter but has reached a different conclusion. “I don’t support warning labels for cellphones, ” said Linet. “We don’t have the evidence that there’s much danger.”

Studies so far suggest a weak connection between EMFs (电磁场) and illness — so weak that it might not exist at all. A multinational investigation of cellphones and brain cancer, in 13 countries outside the US, has been underway for several years. It’s funded in part by the European Union, in part by a cellphone industry group. The final report should come out later this year, but data so far don’t suggest a strong link between cellphone use and cancer risk.

As is known to all, colors appear in every language to express people’s feeling and thoughts. Then, what is the situation in American English?

Red is a hot color. Americans may say they are red hot about something unfair. They are red hot when they are very angry about something. The small hot-tasting peppers found in many Mexican foods are called red hot for their color and their fiery taste. Fast loud music is popular with many people. They may say the music is red hot, especially the kind called Dixieland Jazz.

Pink is a lighter kind of red. People sometimes say they are in the pink when they are in good health.The expression was first used in America at the beginning of the twentieth century. It comes from the fact that many babies are born with nice pink skin that shows that they are in good health.

The color black is often used in expressions. People describe a day on which everything goes wrong as a black day. People or things on a blacklist are connected with things illegal now. But at one time, some businesses refused to employ people who were on a blacklist for belonging to unpopular organizations.

The color green is natural for trees and grass. But it is an unnatural color for humans. A person who has a sick feeling in his stomach may say he feels a little green. A passenger on a boat who is feeling very sick from high waves may look very green.

Sometimes a person may be upset because he does not have something as nice as a friend has. That person may say he is green with envy. Some people are green with envy because a friend has more dollars or greenbacks. Dollars are called greenbacks because green is the color of the back side of the paper money.
