Hundreds of thousands of young children are being given mobiles(移动电话) by their parents against official health advice. One in nine five-to-nine-year olds has a mobile. This will rise to one in five in a year or two, making this the fastest growing group of mobile users.
A report on mobile safety says that while it is not sure whether they hurt users, children should not be allowed to use mobiles as much as grown-ups. This is because their brains are still developing and their bones are thinner, making it easier for mobile phone radio waves to pass through them. Mobile phone companies say they do not aim at under-16s, although some of their mobiles are designed to interest younger children.
Many of the mobiles are paid for as a safety measure so that the child can always call a parent when necessary. However, when children see that their friends have a mobile, it can become popular among them.
Professor Colin at Oxford University, who studies mobile phone radio waves, told BBC News “It’s new technology(技术) and the science is still developing. We have to be very careful about children—if there are any effects they would hurt young children more than grown-ups.” He suggested that children should be encouraged to use text messages rather than spoken conversations, this would reduce the amount of radio waves greatly.
【題組】45. According to Professor Colin, which of the following is TRUE?
(A) Reducing radio waves is a hard task for scientists.
(B) Children should not be allowed to use mobiles.
(C) Scientists usually care for young children more than grown-ups.
(D) Sending each other text message is safer than regular calling.
