问题 What effect does excessive positive ionization have on some people?
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 推理判断题。根据第一段最后一句话,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。据此可以推断接触上述物品可以产生静电,因此选C。A.“使用家用电器”,犯了以偏概全的毛病;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”,文章未提及。
