Primary school should be banana middle school should be apple high school should be orange university should be grapefruit (bananas, apples, oranges and grapefruit are some fruits that we often eat in our lives. Primary school is a carefree transition period, just like a banana. Nothing particularly strong, all children in primary school like to eat it. Middle school is our new starting point. Adolescent children are sour and sweet. High school is the time when we rush to college. The study pressure will be great. Think about how happy my old life was. Think about how sad life is now ... college is a sign of going to society. Going to college means that our life will start a new journey and face new choices. It's like eating grapefruit. It may be a little bitter at first, but it is not so bitter after eating. It's as if we are recalling so many difficult times in the past. )
