【題目】閱讀理解
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 (癥狀)”, 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 (墊子) 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 (接觸) with laptops.
（1）According to the passage, “toasted skin syndrome” can be caused by all the following 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
D.overuse of heating pad and other heat sources
（2）The underlined word “discoloration” in the 2nd paragraph refers to ______.
A.spot
B.darkening
C.sunburn
D.heat
（3）It can be learnt from the passage that laptop users ______.
A.should avoid close skin contact with laptops
B.are likely to develop a certain kind of cancer
C.have known much about the harm of laptop heating
D.should go to see the doctor at once
（4）Some computer producers warn against placing laptops on laps for long periods of time because of ______.
A.the risk for burns
B.the risk of dropping
C.the risk of breaking
D.the protection of back bone
（5）Which of the following might be the best title of the passage? ______.
A.Laptop is Dangerous
B.Skin Damage is Possible
C.A Bad Habit
D.No laps for Warm Laptops

Answer 1

【答案】
（1）C
（2）B
（3）A
（4）A
（5）D
【解析】本文是一篇說明文，從一些案例和研究報告說明：長期的電腦炙烤皮膚與長期暴露在陽光下的皮膚相似，都會造成皮膚病癥，告誡人們不要長時間地直接把筆記本電腦放在膝上。
（1）考查細(xì)節(jié)理解。根據(jù)第一段中的“Doing it a lot can lead to ’toasted skin syndrome (癥狀)‘, an unusual-looking spotted skin condition caused by long-term heat exposure (暴露), according to medical reports.”可知，這種病癥是由于長期的熱暴露所造成。故選C。
（2）考查詞義猜測。根據(jù)句意：在最近的一個案例中，一個12歲的加利福尼亞男孩在幾個月里每天玩幾個小時的電腦游戲后，在左腿上出現(xiàn)了皮膚變色�？芍�，discoloration意為“變色、變暗”。故選B。
（3）考查推理判斷。本文主要從一些案例和研究報告表明，長期的電腦熱烤皮膚與長期暴露在陽光下的皮膚相似，都會造成皮膚病癥。所以從這篇文章中我們可以了解到筆記本電腦用戶應(yīng)避免與筆記本電腦進(jìn)行皮膚接觸。故選A。
（4）考查細(xì)節(jié)理解。根據(jù)倒數(shù)第二段中的“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，一些電腦生產(chǎn)商警告說，不要長時間地把筆記本電腦放在膝上，因為有灼傷的危險。故選A。
（5）考查主旨大意。本文主要從一些案例和研究報告說明： 長期的電腦熱烤皮膚與長期暴露在陽光下的皮膚相似，都會造成皮膚病癥�？芍�本文主要說明使用手提電腦時的危險。故選D。
