    The Ministry of Education reportedly plans to make school admission (许可) age more flexible. As part

of the reform program, it will allow primary schools to enroll students aged under 6, the country's present

age of admission. While some people applaud it, this might not necessarily be a helpful revision.

    Once the current six-year-old limitation is cancelled (取消), no parents will want to send their children

to school at that age while other children enter school at younger age. As a result, Chinese children will

have to go to school increasingly early.

    The earlier they are sent to school, the less freedom young children will enjoy. They will be thrown into

endless examinations. While their heads become filled with knowledge, their simple happiness will decrease.

This is harmful for their growth, especially when they are thrown into the rigors of a curriculum before

they are five years old.

     In countries such as Germany and Australia, parents all hope to send their children to school at an older

age when they have developed more fully physically and psychologically. 

    The current fixed schooling age is an effective mechanism to protect children against harm brought on

by early schooling. If it is broken, Chinese children might again face a more stressful childhood.

A. 7; 7

    school. [ ]

A. no parents

B. perhaps all parents

C. only some parents

D. maybe a half of the parents

3. The children will enjoy            if they go to school earlier. [ ]
