问题 The author thinks sleep is a funny thing as it is necessary for human life.
When insects sleep, they may become inactive no matter whether it is in the day or at night.
选项 A、Y
B、N
C、NG
答案B
解析 第2个小标题Who Sleeps?部分的第1段最后一句：Insects do not appear to sleep，although they may become inactive in daylight or darkness．根据原文，尽管昆虫白天和天黑以后都可能会变得inactive，但它们好像不用睡觉，而题目的前提insects sleep与原文的do not appear to sleep相抵触，故答案为N。
