You are sure not alone. In China, many students are stressed out because of too much homework. But there might be good news for some of them.On Oct 28th, the Education Department of Zhejiang Province polished a draft(提纲) on cutting students’ homework to ask about public opinions and it had became a hot topic. It gives primary school pupils the right to leave their homework unfinished after 9pm, and junior high school students after 10pm, with parents’ permission.Children in Zhejiang will like the draft. However, it has mat strong objections(反对) from parents. Although parents don’t want their children under too much pressure with homework, many disagree to cut homework down.There is a reason for the objections：gaokao, the “all-important” national entrance exam. If schools reduce homework, “the parents, who want their children to get higher scores, must provide them with more after-school trainings,” said a primary school teacher in Hangzhou.The aim of this draft, an official in Zhejiang explained, is to help to treat students differently and make sure they get enough sleep.Chu Zhaohui, a researcher at the National Institute of Education Sciences, also doubted if the guidelines would be carried on. “They are not suitable in the recent social environment.” He said to People’s Daily. “Even if schools make changes, it is difficult to change the way that students study for scores.” He suggests that it would make better sense to make the system of college admission more flexible, and in many other countries, the performance of students is judged by professional institution rather than government.【1】What does underlined “many” in para.3 refer to?A.Children who will welcome the move.B.Parents who are against the move.C.Teachers who don’t want their students to be under some stress.D.The officials who are worried about the move.【2】What is NOT true according to the passage?A.The draft is not welcomed by many parents in Zhejiang.B.Maybe parents will send their children to more after-school training.C.The aim of the draft is to make sure students can have enough time to exercise.D.Students should be treated differently.【3】What does Chu Zhaohui mainly want to tell us?A.Students will have more chance to take part in the activities they like because of the draft.B.The system of college admission should be changed as the school has made changes.C.Students should spend more time doing homework if we change the system of college admissions.D.The performance of students should be judged by their school.【4】What is the best title of this passage?A.Can students have the right to do whatever they like?B.Can parents pay less attention to their kids?C.Can schools have the chance to choose students?D.Can students spend less time doing homework?
