My brother Tom was very selfish when he was a 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 where I couldn’t find. Then he ate it all by himself. He never helped other. He said he is busy. That is, a game of tennis making him very busy. He did not care if something he did made people angrily. For instance, on one night he played strong and loudly music till four o’clock in the morning. But he is difference now. He often helps grandma with housework, helps mum with cooking and helps his classmates with their lessons. want后加to
网友回答
(答案→)want后加to
解析：
【小题1】固定搭配，want to do sth 想做某事。
【小题2】put的宾语是a chocolate cake所以应用代词it。
【小题3】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4】这里other指其他人，不是指一个人所以应用复数。
【小题5】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6】这里应该是谓语动词，因为叙述的是过去的事情所以用made。
【小题7】angry修饰的是名词people所以用形容词而不用副词。
【小题8】在表示在特定的日子前用介词on，one night不是指特定的那一天，所以此处不用on。
【小题9】此处strong和loud修饰名词music所以用形容词不用副词。
【小题10】different形容词做is的表语，意思是他现在不同了。
