被动语态用法小结

　　英语的语态分为主动语态和被动语态。当我们不知道动作的执行者，或没必要提及动作的执行者，或强调动作的承受者等时，常用被动语态。

一、几种常见时态的被动语态

时态 被动语态的构成 例句 一般现在时 am / is / are + 过去分词 The wall is painted every year. 一般过去时 was / were + 过去分词 My sister's bike was stolen yesterday. 一般将来时 will / shall + be +过去分词 This model car will be given to my brother as a birthday present tomorrow. 现在完成时 have / has + been +过去分词 The missing boy has been found safe and sound. 现在进行时 am / is / are + being +过去分词 Two men are being questioned by the police. 过去进行时 was / were + being +过去分词 The roads were being repaired when I passed by. 二、在使用被动语态时，应该注意以下几个问题：

1. 一些表示静态意义的及物(短语)动词没有被动语态。常见的这类(短语)动词有：have, hold, cost, equal, join, mean, wish, own, suit, fit, agree with, belong to, look like等。如：

This big hall built last year can hold about 3,000 people.

2. 当动词look, smell, sound, feel, taste等用作系动词时，不能用于被动语态。如：

The eggs I bought last week smell bad.

My mother's voice sounded a little strange on the phone.

3. 有些动词，如：cut, wash, write, sell, wear, lock等，如果用来表示主语的属性、特征时，不用被动语态。试比较：

The blue coat washes well. (表属性、特征)

这件蓝外套好洗。

The blue coat was washed the day before yesterday. (表动作)
