语态,被动,完成,现在
. 被动语态

主动语态:主语 主动 执行 被动语态:主语 被动 承受

例句: The lazy sheep was caught by the gray wolf again!



1. 被动语态的基本机构:be +及物动词 过去分词



2. 主动变被动的基本规则:

主动语态: 主语 + 谓语动词 + 宾语 + 其他成分

被动语态: 主语 + be +过去分词 + by +宾语 + 其他成分

1 Many people speak English.

1 2 3

被动句: English is spoken by many people.

3 2 1

2 He cheated her.

1 2 3

被动句: She was cheated by him.

3 2 1

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 _____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 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:______________________________________________

2say, 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.

. 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 I have studied English for 10 years. 2. 标志性的时间状语:

already___________, yet_____________ _____________

ever_____________ never___________, before___________

In the last/past + 一段时间________________________________ So far ________________

For + 一段时间___________________________

Since + 过去的时间点 since thensince two years ago, since 1996…… + 从句(过去式)

次数(twice three times , four times……

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

yet用于一般疑问句或否定句

_______ you eaten lunch _________? I havent eaten lunch ________. 2Have you ever read this story (before)? -----I have never read it.

3) In the last three weeks, I have read 5 books. 4) We have known each other for 5 years. 5) Qingdao has changed greatly so far.

6) I havent seen my teachers since I left school. 7)I have lived here since 2010. (since 3 years ago)

3、重点词组辨析

have/has gone to 去了……(人未回)

Have/has been to 去过……(人已回)

Have/has been in ……多久(有一段时间)



4. 与延续性的时间状语 连用的必须是延续性动词

初中阶段常考的延续性时间状语: 1for +一段时间

2Since + 过去的时间点 + 从句(过去式) 3How long……?
