Li Hua and Wang Hai are two students of Senior Three. 1. of them work hard but they have various learning methods.

Li Hua listens to her teachers 2. (attentive) and asks her teacher 3. help as soon as possible if she has some problems. Because of this, she spends less time 4. (do) her homework, so it is 5. (certainly) that she can keep energetic in the day. However, Wang Hai has quite a 6. (difference) way of learning 7. (compare) to Li Hua. 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, 8. makes it difficult for him 9. (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 10. (she) learning method.
