被动语态和主动语态的区别

从结构来说,被动语态的公式是be动词+动词过去分词,意思是被怎么怎么样了,其中的be动词随句子时态变化而变化,比如我昨天吃了个苹果,I ate an apple yesterday.这是主动语态,苹果被我吃了,The apple was eaten by me yesterday.各种时态中的be动词变化你需要自己去学习,因为说起来很麻烦,还会把你搞晕.再从表达来说,被动语态要委婉一点.有一个难点我用句子来说明,我发现他玩电脑,I found him play computer yesterday.这个句子变为被动语态千万不可以是
He was found play computer by me yesterday.应该用不定式来修饰play,所以应该是He was found to play computer by me yesterday.
