【简答题】
ASK LASKAS YOU’VE GOT QUESTIONS. SHE'S GOT ANSWERS My children go to a primary school where they are not allowed to play football in the playground for fear that a child might be hurt. Besides, now the school says there must be no homework because the local secondary school can't keep up with the amount of homework given in the primary school. Can the school do this? Puzzled Dad It can't if enough parents do something about it. It is not just schools. We live in a society which wishes to get rid of risk. However, schools should have a little common sense and courage. Children need risk if they arc to grow up self-sufficient and confident. They need homework, too, if they are to fulfill their academic potential. Complain, loudly. I have a beautiful teenage daughter who spends an hour making up her face in front of the mirror every day. I tell her to go easy. She just gets mad or bursts into tears. How can I make her understand she's beautiful the way she is. Plain Mom You can't. Your daughter is at the age when she's trying to look beautiful, trying on new masks. And if her friends all dress up as she does, you're in for an extra hard time. Support her and tell her she's beautiful — even if she looks ridiculous for now. Then invite her to join you for a day at a spa . Let her try various looks until she's comfortable in her own skin. 小题1:Why are the children not allowed to play football in the playground? A.The school is afraid that children might be injured.
