Li Bin is a student. He used to be late for school and he didn't listen to the teacher carefully in class. He didn't do his homework, either so he god bad grades in the past. Now with Wang Ming's help, he has made great progress. He works hard every day. When he has problems, Wang Ming always help him to solve them and he also helps him review what is learnt. So now Li Bin is a good student,too. He is never late for school and he is one of the top students in his class. So when someone is in difficulty, we should always get ready to give a hand.
