I can not see it at all

　　After supper, the parents were busy playing mah-jong with the guests. At this point the mother thought of something and said to her son who was watching TV, "Honey, go see if the kitchen light is on or not?" After a while, her son returned and said, "Ma, the kitchen is so dark that I cannot see it at all."

　　晚饭后，父亲和母亲都忙着和客人玩麻将，这时母亲忽然想起点儿事来，便对正在看电视的.儿子说道：“宝贝，去看看厨房里的灯是不是还开着呢?” 过了一会儿，儿子回来说：“妈，厨房里太黑了，我根本就看不见。”
