小题1:         
Education should be aimed to make better citizens instead of making money. If you’re interested in making money, you should start your own business other than schools. Now it’s high time that we put an end to the industrial management of education(教育产业化) and have it benefit all the people instead of the few rich ones.
小题2:         
We should take concrete(切实的)measures to lessen the students’ heavy burden of homework.. We must kick off concrete policies and rules instead of talking empty talks. We must take action. Only 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 not only have the equal right to go to the local public schools, but also have the rights to take part in the local national college entrance exam instead of being forced to go back to our native place.
小题4:         
School choice has become a serious educational problem. To solve this problem fundamentally, 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(轮岗)among all the schools.
小题5:          
The government is unwilling to spend enough money on education. The key schools turn to parents for money to build new buildings and labs and increase their teachers’ income. This makes a wider gap(差距) between key schools and common schools. Therefore, in order to realize the balance of education, the government should offer more help to weak schools.
