Li Hua and Wang Hai are two students of Senior Three．．Both of them work hard but they have different learning methods．Li Hua listens to her teachers attentively, tries to catch everything that the teachers say in class and consults her teachers as often as possible if she has some problems．Because of this, she spends less time doing her homework, so it is certain that she can go to bed earlier and she always keeps energetic in the day．
However, Wang Hai has quite a different way of learning．He likes to sit up late at night doing his homework, so he often feels sleepy in class．As a result, he misses lots of key points and it usually takes him more time to finish his homework, which makes it difficult for him to concentrate on what he is doing．
In my opinion, Li Hua learns more effectively in class and has more free time to enjoy herself．So I prefer her learning method．
