短文改错（共10 小题，每小题1分，满分10分）
My brother Tom was very selfish when he was little boy. He did not want share things with
other people. For example, when he bought a chocolate cake, he put them in a secret place,
that I couldn’t find. Then he ate it all by himself. He never helped other. He said he is busy.
In other words, a game of tennis made him very busy. He did not care if something that he did
it made people angry. For instance, one night he played strongly and loud music till four o’clock
in the morning. But he is difference now. He often helps grandma with houseworks, helps mom
with cooking and helps his classmates with their lessons.

解析：
【小题1】little boy是可数名词，要加不定冠词a
【小题2】固定搭配，want to do sth 想做某事。
【小题3】put的宾语是a chocolate cake所以应用代词it。
【小题4】定语从句，关系词在从句中做find的宾语所以用关系代词which/that,作宾语时关系代词还可省略。
【小题5】这里other指其他人，不是指一个人所以应用复数。
【小题6】said是过去式，它的从句中的谓语动词应是过去式，所以用was.
【小题7】that he did是定语从句修饰something，that在定语从句中做宾语，去掉it。
【小题8】此处strong和loud修饰名词music所以用形容词不用副词。
【小题9】different形容词做is的表语，意思是他现在不同了。
【小题10】housework是不可数名词
