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.

How to teach a child to respect

As a child grows out of being an infant and begins to notice and react to the world around him, you may find yourself wondering how you possibly impart (传授) all of the things that he needs to become a responsible, respectful adult. 【1】 A child who learns to respect all he meets not only receives respect from others, but also learns to respect himself as well. Here are some instructions.

Show your child respect. This is perhaps the best way to teach your child how to respect others. Listen to your child by giving him your full attention and he will learn to listen to you, understanding how important this is in communication.

2 The more you say “please” and “thank you” to your child, the more likely he will learn to use them with you and others. Politeness then becomes a normal part of any conversation.

Agree to disagree. 3 Explain your decision so that he will understand your reasoning and expect respectful responses. Disagreeing with you doesn’t equate to disobedience (违抗).

Control your impulse (冲动) to overact. When a situation arises between you and your child that requires calmness, keep in mind that you are supposed to be modeling correct behaviour. 4___

Praise, praise, praise! So much is focused on what a child does wrong and how to correct it that the accomplishments are not celebrated enough. 5___

A. Teach manners by using polite requests and responses.

B. Try to remember that a child won’t always agree with you.

C. Respect is necessary for a meaningful and successful life.

D. If he sees you lose your temper, he is more likely to respond that way in future.

E. A child may act like he pleases, but will respect being given limits.

F. When you see your child exhibit respectful behaviour, make sure he knows just how proud you are of him.

G. Setting a good example is the best way to start a child on the path to respect.
