A. The Eskimos seldom suffer from colds. B. Colds are not caused by cold. C. People suffer from colds just because they like to stay indoors. D. A person may catch a cold by touching someone who already has one. 参考答案:C 答案解析:推理题 感冒是通过病毒传染的,呆在室内显然不应该是感冒的原因。倒数第二段最后一句人们易于在天冷的时候感冒是由于人们倾向于天冷时一起呆在室内,从而便于病毒传染。因此C项不正确。
