你做过傻事儿吗?我做过。有一次,爸爸下班回来,高兴地对我说:“瞧,我买了一块手表送给你妈妈,这手表有三防:防水、防震、防磁……”可我发现妈妈洗衣服时不戴表,干家务活时不戴表,就连睡觉也不戴表。我觉得莫名其妙,这表不是能三防吗?干吗不戴呀!这表真的能三防吗? Have you done stupid thing? I have done. Once, my father came back from get off work and said happily to me: “Look, I bought a watch for your mother. This watch has three defenses: waterproof, shockproof and antimagnetic ...” But I found my mother did not wear a watch when washing clothes, When you do your housework, you do not wear the watch. You do not even have to sleep on the table. I feel baffling, this table is not able to three defenses? Why not wear it! This table can really three defenses?
