第二节读写任务（共1小题，满分25分）

阅读下面短文，然后按照要求写一篇150词左右的英语短文。

The Guangzhou Children’s Palace and Urbanities Growing magazine last week published the results of survey about how children and parents view thankfulness. 84% of parents think that today most children do not feel a sense of thankfulness toward their parents. 90% of the parents said that the key to teaching children to be thankful toward their parents is for parents to set a good example themselves. If parents expect their kids to be more thankful to them, they themselves should be thankful toward their kids as well as toward others.

How do children understand the idea of being thankful? Most children think that being thankful means repaying those who have supported them. 44% of the children think that they should be grateful to those who once helped them or brought them happiness; 36% of the children think that if someone helped them before, then they should do something for him or her in return; and 20% said that they should be grateful to their parents for bringing them up. No kids think that being thankful was something out of date.
