| Can you help me now, my dear friends? I have a 1 for you to help me to solve now. My 14-year-old daughter, Kate, is in Grade 7. Every 2 we get into homework battles (争执). Three afternoons a week, she 3 activities after school and gets home late. She always does her homework 4 the end of a weekday. 5 two days, she gets home early. 6 she thinks she should have some time to watch TV and play. 7 Kate at last sits down to do her homework, she just wants me there to help her all the time. I like to 8 that, but I think she should do it by herself. And what's more, I have many other things to do. I just feel that children these days have much 9 homework than we did when we were young. I'm really worried about Kate and I don't know 10 I should do. Do you have any ideas? | ||||
