make sb do sth这个短语中的do sth是不带to的不定式.在不定式作主补的时候要带上to
如：the teacher made me to stand up.
变成被动是这样的：i was made to stand up by the teacher.
被动语态有：is/am/are done:一般现在时
was/were done：一般过去时
will be done：一般将来时
would be done：一般过去将来时
am/ is/are being done：现在进行时
was/ were being done：过去进行时
has/have been done：现在完成时
had been done：过去完成时
will have been done：将来完成时
would have been done：过去将来完成时
过去分词是非谓语动词,它也可以表被动表完成
如：i heard my name called.这个句子中的called就是过去分词,它在这里是指被叫,表被动.
