high school和middle school
一般来说，high school和middle school的定义因国家的不同而有所不同。比如说，
对于HIgh school：“In Britain, a high school is a school for children aged between eleven and eighteen.In the United States, a high school is a school for children usually aged between fourteen and eighteen.”
对于Middle school：“In Britain, a middle school is a state school that children go to between the ages of 8 or 9 and 12 or 13. In the United States, a middle school is a school for children in the fifth to eighth grades, between the ages of 10 and 13 or 14.” （柯林斯第五版）
这主要与每个国家的教育制度有关。
