问题
What effect does excessive positive ions have on some people? [br] According to the passage, static electricity can be caused by ______.
选项
A、using home-made electrical goods
B、wearing clothes made of natural materials
C、walking on artificial floor coverings
D、sorting food in a refrigerator
答案
C
解析
文章第一段最后一句话提到,这种static electricity(静电)可能来源于地毯,人造纤维衣物,电视,复印机和电脑显示器。据此可以推断接触地毯可以产生静电,因此选C。A“使用家用电器”过于绝对,并不是所有家电都产生静电。B“穿着天然材质的衣物”不会引起静电。D“对冰箱食物进行分类”未提及。
