CHICAGO- Have you ever worked on your laptop computer with it sitting on your lap, heating up your legs? If so, you might want to rethink that habit from now on. Doing it a lot can lead to “toasted skin syndrome (症状)”, an unusual-looking spotted skin condition caused by long-term heat exposure (暴露), according to medical reports.
In one recent case, a 12-year-old boy from California developed a skin discoloration on his left lap after playing computer games a few hours every day for several months. “He recognized that the laptop got hot on the left side; however, he did not change its position,” Swiss researches reported in an article published Monday in the journal Pediatrics.
Another similar case is a Virginia law student who needed treatment for the spotted darkening on her leg. Dr. Kimberley Salkey, who treated the young woman, learned the student spent about six hours a day working with her computer placed on her lap. As Dr. Salkey later learnt, the temperature under the laptop could reach 51 degrees. That case, from 2007, is one of 10 laptop-related cases reported in medical journals in the past six years.
The condition can also be caused by overuse of heating pads (垫子) and other heat sources that usually aren’t hot enough to cause burns. It’s generally harmless but can also cause such permanent (永久的) skin darkening. In very rare cases, it can cause damage leading to skin cancers, said the Swiss researchers, Drs. Andreas Arnold and Peter Itin from University Hospital Basel. They do not mention any skin cancer cases linked to laptop use, but suggest, to be safe, placing a carrying case under the laptop if you have to hold it on your lap.
Dr. Kimberley Salkey said that under the microscope, the affected skin is similar to skin damaged by long-term sun exposure.
Major producers including Apple and Dell warn against placing laptops on laps or exposed skin for long periods of time because of the risks for burns. In the past, “toasted skin syndrome” has happened to workers whose jobs require being close to a heat source, including bakers and glass blowers, and in people who gathered near hot stoves to stay warm.
Dr. Anthony J. Mancini, chief at Children’s Memorial Hospital in Chicago, said that it’s unlikely that computer use would lead to cancer since it’s so easy to avoid close skin contact (接触) with laptops.

【题目】阅读短文,下列问题
B
My grandfather is an eighty-year-old man. He always complains about how fast things have changed, and he often says that life used to be better.
Families aren't families the way they used to be. A lot of families have broken down. If husband and wife have problems with their marriage, they no longer stay together. And mothers used to stay at home and take care of their children, but now everyone is working. No one has time to look after children at home.
And the cars! Most families have a car now. We used to walk five miles to school every day, even in winter. But now children don't. And in school, the children don't have to think anymore. In math class,for example, we used to add, subtract (减), multiply (乘) and divide (除) in our heads. Kids don't use their heads anymore; instead, they use calculators (计算器).
Most families have computers now. In the past, we didn't have computers. We didn't even have lights. My mother used to spend all day cooking in the kitchen. But now fewer and fewer people eat home-cooked food.
