周末清晨,老妈上街买菜,我不自觉地坐到了电脑前。老妈回家一看我又玩电脑,不管三七二十一直对我大吼:“我才出去一会儿,你就开始玩电脑了,你知不知道电脑有辐射呀!”天真的我点了点头,老妈叹了口气:“你明知道电脑有辐射,还要玩!你知不知道辐射会让人脸上生雀斑(quèbān),会让你的视力下降啊!!” Weekends early in the morning, the mother went to the streets to buy food, I do not consciously sat in front of the computer. Mom went home to see I play the computer again, no matter thirty-seven twenty-one always shouted to me: “I went out for a while, you started to play the computer, do you know the computer has radiation!” Naive I nodded, my mother sighed: “You know the computer has radiation, but also to play! Do you know that radiation will make people face freckles, will make your eyesight drop ah !! ”
