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, as this would reduce the amount of radio waves greatly.

When memories of holiday pumpkin pies(南瓜馅饼)are not fresh any more, large?pumpkin growers are already planning next year’s crop. Every year farmers around the world work very hard to see who can grow the world’s largest pumpkin.
The present world record belongs to Steve Daletas of Oregon. His pumpkin weighed 1,385 pounds (628 kilograms). That’s heavier than large bears! In August the pumpkin grew 29 pounds (13 kilograms) per day! Our reporter spoke with Andrew Sabin, who was one of the organizers of the 2003 Large?Pumpkin Weighing Competition(比赛).
To grow a large pumpkin, Sabin explained, you need the right seed and the right soil, and a lot of hard work.“It’s like a baby,” he said. “You look at your baby every day.”
All the hard work leads up to the weighing competitions, which usually take place in October. Top prize winners can earn thousands of dollars.
Just getting the large pumpkins away from the farm can be very difficult. The pumpkins are so heavy that farmers often have to use forklifts(叉车)to move them.
What do farmers do with the large pumpkins after the competition? According to Sabin, restaurants often buy the pumpkins for show. Top winners can also sell their pumpkin seeds to other farmers hoping to beat the world record the next year.
Would the large pumpkins be made into pumpkin pies? Not likely, Sabin said. “They don’t taste so good as the small pumpkins that are grown to eat.”
Animals seem to like them though—at least one large pumpkin was fed to an elephant at the Oregon Zoo!
