请阅读下列相关信息，并按照要求匹配信息。选项中有两项多余选项。
小题2:______ Concrete measures should be taken to lessen the students’ heavy burden. Not empty talks but concrete and solid policies can guarantee all the students grow soundly. 小题3:______ My parents are farmer-turned workers. I think we should be treated equally with the local children. We should have equal chance to go to both the local public schools and take the national College entrance exam rather than go back to our native places. 小题4:______ School choice has become a serious educational problem. To solve this problem, we must stick to the balanced development. The government should offer more support to weak schools and have all the teachers exchange the round hillock work among all the schools. 小题5:______ The government’s unwillingness to spend enough money on education makes key schools turn to parents for money to build new buildings and increase teachers’ income, widening the gap between key schools and common schools. Therefore, in order to realize the balance of education, the government should offer more help to weak schools. |
