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 electric goods
B、wearing clothes made of natural materials
C、walking on artificial floor coverings
D、copying TV programmes on a computer

答案C

解析 选项中没有与文章直接对应的,要对第一段最后一句的内容进行综合考虑。能够引起静电的有地毯、衣物等人造纤维、电视、复印机和电脑等。而"copying TV programmes"虽然有电视和电脑,但并不属于能够从原文推断的范围。而人造地板覆盖物极有可能是人造纤维地毯。
