3.主动句变被动句的主要规则：
(1). 人称代词主格做主语，宾格做宾语。
(2). 被动语态基本结构：be+及物动词的过去分词
(如果是不及物动词，其过去分词应带有相应的介词)
He gives up smoking. 被动句：______________________________
(3). 被动语态中的be 是助动词，有人称、数和时态的变化。
一般现在时被动语态为：
一般过去时被动语态为：
一般将来时被动语态为：
现在完成时被动语态为：
(4).情态动词+ be done
由上可见，被动语态的时态由_____be 动词___ 来体现。
(5). 被动语态中，by+动作的发出者放在句末(课省略)，by 表示“由，被”的意思。

4.被动语态的注意点
（1）“三看一听”hear, see, watch, notice，使役动词make等主动句中to 走开，被动句中to 回来。
I heard my sister sing in her room yesterday.
被动句：
My mother always makes me do some housework.
被动句：______________________________________________
（2）say, believe, consider, know, expect, think 等词接宾语从句，变被动句用
It is / was said/believed…. that……….
People believe he told the truth.
被动句：_________________________________________
（3）常见无被动的词：
happen 意为“发生”时，主语为物，sth happen to sb, 无被动
belong to, take place, rise, sell well, remain, run out, come true等无被动
(4) 感官动词__feel, look, smell, taste, sound_, 主动表被动
The news sounds terrible.
二. 现在完成时
1、语境分析
①动作发生在过去，已完成，强调对现在有影响
---Are you hungry? ---No, I have had breakfast.
②动作发生在过去，未完成，持续到现在或未来

So far ________________小学体育教案
For + 一段时间___________________________
Since + 过去的时间点since then，since two years ago, since 1996……

注意：1）already用于肯定句，I have already eaten lunch.
