判断下列句子是否正确,不对的改正（英语题）Has he sell his old car?Mr.Smith has always been a good teacher.He has been several countries.Jim returned to home at nine o'clock last night.You'd better comes bake before ten o'clock.

You'd better=You had berrer
had berrer后面跟动词原形

1.sell -sold。 Has 要用完成时
2Been-being，always表示持续状态，要用进行时，或者去掉always
3.been to 表示已经去过，gone to表示去了还没回来
4.returned 去掉to ，home是副词
5.comes- come ，You'd better do sth

1.sell -sold
2.正确
3.改为He has been to several countries.
4.去掉to
5.comes -come

1.sell -sold 3.been to 4.returned 去掉to home是副词 5.comes- come You'd better do sth

第一句：sell改sold,因为是已经完成时
第二句：always去掉,因为always是一个持续的状态
第三句：been改成gone to,因为been是一个状态,是不能代表去过
第四句：to去掉,因为Home前是不能加介词的
第五句：comes改成come,因为有这么一个词组had better do sth

He has gone to several countries.
