I have a robot friend, Robbi. It looks like my toy car because it moves on four wheels. It is always helpful.

“Come on, Robbi! Bring me milk.” “Yes, Sandy,” says Robbi. It goes to the kitchen and comes back with a glass of milk. It can find milk among orange juice, water, apple juice.

【小题1】 Who is Robbi?

WARNING: Holding a cell phone against your ear or putting it in your pocket may be bad for your health.

Devra Davis, an epidemiologist(皮肤病专家) who has worked for the University of Pittsburgh, has published a book about mobile phone radiation（辐射）"Disconnect." Davis studies how often brain cancer happens during different age groups. She finds a big increase in brain cancer in the 20-to-29 age group and a drop for the older people.

Children are more easily hurt by radiation than grown-ups, Ms. Davis and other scientists point out. But no studies have yet been finished on cell phone radiation and children, she says.

Henry Lai, a research professor, began lab radiation studies in 1980 and found that mice exposed to(暴露在) radiofrequency（电波频率）radiation had destroyed DNA in their brains.

Ms. Davis recommends using wired earphones（有线耳机）or the phone's speaker. (2)Children should send text messages rather than call, she said, and pregnant（怀孕的） women should keep phones away from their bodies.
