He told me his son was watching TV. 他告诉我他儿子在看电视。 ②从句动作发生在主句动作之后,从句须用过去将来时。例如:
He said he would post the letter. 他说他将要寄这封信。
They did not know when they would go to the Great Wall. 他们不知道什么时候去参观长城。
③从句动作发生在主句动作之前,从句须用过去完成时。例如:
He said he had posted the letter。 他说已经把信发了。
They asked me whether I had been there before. 他们问我以前去没去过那里。 但是,如果从句有具体的过去时间状语,尽管从句动作发生在主句动作之前,有时仍用一般过去时。例如:
She told me her brother died in 1960. 她告诉我她哥哥1960年去世的。 They said they checked everything yesterday. 他们说昨天他们全部检查过了。 另外,从句说的是一般真理或客观事实,即使主句用过去时态,从句仍用一般现在时。例如:
The teacher told the pupils that the earth is round. 老师告诉学生们地球是圆的。 Somebody told me you are a writer. 有人告诉我你是个作家。
除了宾语从句外,其他名词性从句(主语从句、表语从句和同位语从句)一般也要遵守这种时态呼应的规律。而状语从句和定语从句则是根据本身意思的需要选用适当的时态。例如:
He saw the boy whose mother is our teacher. 他见过那个他妈妈是我们老师的男孩。
It was not so hot yesterday as it is today. 昨天没有今天这样热。

Chapter 3. 动词的语态
一、概念:
动词的语态是动词的一种形式,表示主语和谓语之间语法或语义的关系。英语的语态有两种:主动语态(active voice)和被动语态(passive voice)。主动语态用于主动句,表示主语是动作的执行者。被动语态用于被动句,表示主语是动作的承受者。主动语态的构成方式与动词时态相同,而被动语态由助动词“be+过去分词”构成,有人称、数、时态的变化。
二、英汉两种语言在表达被动方式上的差异:
汉语表达被动语态非常简单明了,用“被”“遭”“受”等词来表示,如“被捕”、“被杀”、“受到凌辱”等。而英语表达被动的方式也不复杂,用“助动词be+动词的过去分词”表示。其中助动词be有人称、数量和时态的变化,而这正是英语被动语态的难点。 三、相关知识点精讲: 1、被动语态的构成
被动语态由“be+及物动词的过去分词”构成。这里要强调一定是及物动词的过去分词,因为不及物动词不能带宾语,也就不可能有被动语态。英语主动语态有16个时态;被动语态常用的有8个,以give为例说明如下:
时态 一般现在时 一般过去时 一般将来时 现在进行时 过去进行时 过去将来时 现在完成时 过去完成时 动词形式 Am/is/are given Was/were given Shall/will be given Am/is/are being given Was/were being given Should/would be given Has/have been given Had been given 被动语态的疑问句是将第一个助动词移到主语之前、句末用问号;否定式是在第一个助动词后加not或never等其他否定词、句末用句号。例如:“During the interview, were you
asked questions in English?” “No, I wasn’t asked questions in English.” 2、被动语态的用法
1) 不知道或没有必要指出动作的执行者。换个说法,有一件事情不知道是谁干的或者不想说出是谁干的,这时就用被动语态。
例如:These fighters are imported from Russia. 这些战斗机是从俄国进口的。 2) 说话或发表意见时,为了显得客观公正,也常用被动语态。例如:
He’s said/believed/reported to be in the U. S. A. 据说/据信/据报道他在美国。 常用句型(that后面跟句子):It is said that……. 据说;It is reported that……. 据报道;It is hoped that希望;It is believed that……. 人们相信;It is announced that……. 据宣布;it is (well) known that……. 众所周知;It has been decided that……. 已经决定;It is supposed that……. 人们认为;It is suggested that……. 有人建议;It must be remembered that……. 务必记住;It is taken for granted that…….被视为当然;It is thought that… 大家认为 3、主动句变被动句的注意事项 1)时态不能改变;
2)变为被动语态后,谓语动词要和被动语态的主语在人称、数上保持一致。还要作如下变动:把主动语态的宾语变为被动语态的主语;主动语态的主语放在by的后面,组成介词短语,再把这个介词短语放在被动语态的谓语动词之后。在动作的执行者无须说明或不必要强调时,by短语可以省略。例如:
Somebody has warned us to be careful of rats.→We have been warned to be
careful of rats.
3)如果主动语态有两个宾语(直接宾语和间接宾语),变为被动语态时,可将其中任何一个宾语变为主语,另一个不变。但较常见的是将间接宾语变为被动语态的主语。例如:
The reporters asked the president some questions. 记者们问了总统一些问题。 →The president was asked some questions by the reporters. ( 变间接宾语为主语)
→Some questions were asked the president by the reporters. (变直接宾语为主语)
注:①感官动词主动语态的宾语补足语是不带to 的不定式,变为被动语态时,该不定式前要加\。例如:
The teacher made me go out of the classroom.→I was made to go out of the classroom.
②情态动词+ be +过去分词,构成被动语态。
4、含有情态动词的被动语态:句中含有情态动词时,其被动语态的结构是:情态动词+be+过去分词。例如:
This book may not be taken out of the reading room. 这本书不允许带出阅览室。 5、不能用于被动语态的动词
1)不及物动词或不及物动词短语不能用于被动语态,因为它们没有宾语。动词如:die,end(vi. 结束), fail,happen, last, lie, sit, spread, stand;词组如:break out, come true, fall asleep, lose heart, take place。例如:
