【题目】阅读理解
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.

EXCEPT ______.
A.being close to a heat source or hot stoves
B.long period of direct contact to hot laptop
C.using one’s laptop with a carrying case

（4）Some computer producers warn against placing laptops on laps for long periods of time

【解析】这是一则新闻报道，讲述一种由于上时间在大腿上使用笔记本电脑而导致的“烤皮综合症”。
⑴细节理解。根据第一段末提到的 caused by long-term heat exposure (暴露)可知烤皮综合症是皮肤长时间暴露在高温下而引起的。A.靠近热源或炙热的火炉；B.长时间与很烫的笔记本电脑直接接触；C，使用装在盒子里的笔记本电脑；D，过度使用过热的平板和其他热源。四个选项与定义对比可知C不会造成“烤皮综合症”
⑵细节理解。根据句意：加利福尼亚的一个12岁男孩在连续几个月每天玩几个小时的电脑游戏之后形成了一种皮肤……。spot斑点；darkening变暗；sunburn晒伤；heat热。结合下一段第一句Another similar case is a Virginia law student who needed treatment for the spotted darkening on her leg另外一个类似的病例是弗吉尼亚的一位学法律的学生，她的腿上的块状黑斑需要治疗。所以选B。
⑶推理判断。根据文章中描述烤皮综合症的形成原因可知笔记本电脑的使用者应该避免把笔记本电脑直接放在靠近皮肤的地方。故选A。
⑷细节理解。根据倒数第二段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. 可知主要电脑制造商苹果和戴尔警告不要把笔记本电脑上时间放在腿上因为有烫伤的危险。故选A。
⑸主旨大意。Laptop is Dangerous笔记本电脑是危险的；Skin Damage is Possible皮肤损坏是可能的；A Bad Habit一个坏习惯；No laps for Warm Laptops腿上不要放热的笔记本电脑。根据文章的意思可知“烤皮综合症”是长时间把笔记本电脑放在腿上引起的，故选D。
