Ⅱ. 阅读理解。 Do your parents help you with schoolwork or other events Do you think they are giving you too much help Du Peng, 18, from Hebei, has a story to share. He said that while in middle school, his mother asked him to enter an English speaking competition. To help him win, Du's mother once asked an English teacher to help write a speech draft(草稿). “Although I got good results at the competition, I didn't feel proud,” Du said. Du is not alone. Nearly 90 percent of Chinese parents said that they often helped their kids too much in school, according to a recent survey of 1,540 parents done by China Youth Daily. Children, on the other hand, want to do things by themselves. “Doing things ourselves gives us a strong sense of achievement,” said Liu Jiawei, 13, from Jilin. “We will leave our parents sooner or later. So it's better to develop skills and live independently as early as possible.” Some, however, think parents have good reasons to help. Jiang Qi, 12, is from Beijing. He said that his parents would sometimes help him by making PowerPoint presentations and creating handmade works. “If my parents didn't help me while other students still got help from their parents, I would be criticized(批评) for not doing as well as others,” Jiang said. “If schools could set more reasonable criteria(标准) and stop unfair competition, the situation would be improved,” Jiang's mother said.
