二、宾语从句 The Object Clause
1、宾语从句 宾语从句的引导词 宾语从句在复合句中起宾语作用,可以作动词的 宾语,也可以作介词的宾语。 引导宾语从句词有连词that,if,whether 连接代词who,whose,what,which, whoever, whomever, whatever, whichever 连接副词when,where,how(以及how构成的词 组), why等。

1.I hear (that)___________.(一小时后会回来)

2.He said (that)___________.(他非常想我们) 3.The teacher told us (that)_____________. (地球围绕太阳转)

宾语从句中的连接词that 在以下三种情况下不能省略: ①当that 从句与另一名词性从句并列作宾语时, 第二个从句起that引导词不能省; ②当that作介词宾语时, that不可省掉。 ③用it做形式宾语的宾语从句。 1.Everyone knew what happened and that she was worried. 2.The reason lies in that she works harder than the others do. 3.I think it necessary that you should read English aloud.

2.由从属连词if / whether 引导的宾从
if / wether he will go to the ? I want to know _____________________ park with us (他是否和我们一起去公园) if / wether he can come Ask him _______________ (他是否能来) I don’t knowWether it is going to ______________(是否要下雨) rain or not whether or not 连在一起引导宾语从句时不用if

3.由连接代词(what, who, whom, which,whose) 连接副词(when, where, how, why)引导的宾从 ? He asked _________________? who could answer the question (谁能回答这个问题) whom they are waiting ? Doyou know _________________ ?for (他们在等谁) whose handwriting was the ? He asked _____________________? best in the class (谁的书法是班上最好的) when we’ll have a meeting? ? Please tell___________________. (我们什么时候开会)

? Can you tell me ______________ where he is ( 他在哪儿) ? Could you tell me ______________station? how I can get to the (怎样到达车站) why the train was late? ? Would you tell me _______________ (火车为什么晚点)
注:因为连接代词或连接副词在从句中担 任一定的句子成分, 具有一定的意义, 所以 不可以省略。

4.带how的词组也都可以引导宾语从句
1.Could you tell us how much it costs to fly to Hainan? 2.Could you tell us how often you go abroad for a holiday? 3.Could you tell us how long the meeting will last? 4. I don’t know how far it is to the cinema. 5.Please tell us how many students there are in your school. 6. Please tell us how soon you will be ready. Can you tell us how old his brother is?

二、注意正确使用时态

1. 如果主句是一般现在时、一般将来时或祈使句时,宾 语从句时态不受限制 I hear he is here today/ he was here yesterday/ he will be here tomorrow. 2. 如果主句是一般过去时,宾语从句应与主句保持一致, 即使用过去时态的某种形式。 He said he was watching TV/ he had swept the floor/ he would play football after school. 3. 如果宾语从句所叙述的是客观事实、自然现象、科学 真理等时,从句不受主句限制,用一般现在时。 Everyone answered there are sixty minutes in an hour.

三、 注意否定的转移:

主语谓语动词为think, consider, suppose,believe,
expect, guess, imagine等, 其后的宾语从句若含

有否定意义, 一般要把否定词转移到主句谓语上
I don’t think that this dress fits you well. 我认为这件衣服不适合你穿。 I don’t suppose that it is true. ? ? ? ? ? 我认为那不是真的。 一Do you believe it will clear up? 一I believe so. 我认为会这样。 I don't believe so.(或I believe not.) 我认为不会这样。

四、 doubt问题

同位语从句与定语从句区别
1. 从词类上区别
同位语从句前面的名词只能是idea, fact,

news, hope, belief, suggestion, proposal, word, thought, doubt, truth, possibility, promise, order等表抽象意
义的名词,而定语从句的先行词可以是名 词、代词、主句的一部分或是整个主句。

He told me the news that he would come home from aboard soon. Word came that he had been abroad. 据说他已经出国了。 (同位语从句) Our team has won the game, which made us very happy. (定语从句) 我们的队赢了, 这让我们很高兴。

2.从性质上区别 定语从句是从句对其先行词的修饰或 限制,属于形容词性从句的范畴;而同 位语从句是从句对前面抽象名词的进

一步的说明和解释,属于名词性从句
的范畴。如:

The news that our team has won the game is true. 我们队赢了那场比赛的消息是真的。 (同位语从句, 补充说明news到底是一个什 么消息) The news that he told me yesterday was true. 昨天他告诉我的那个消息是真的。 (定语从句, news在从句中作told的宾语)

3. 从引导词及其在句子中的成分上区别 有些引导词如how, whether, what 可以 引导同位语从句, 但不能引导定语从句。 如: That question whether we need it has not been considered. 我们是否需要它这个问题还没有考虑。 (同位语从句)

引导词that引导定语从句时,在从句中 一般作主语或宾语 (指物时还可以用

which代替),并且作宾语时常常省略,
that在同位语从句中仅起连接作用,不

充当任何成分,并且不能省略,也不能
用which来代替。如:

The order that we should send a few
people to help the other groups was received yesterday. 我们应派几个人去帮别的几个小组的 命令昨天收到了。 (同位语从句, 是对order的具体解释 that虽不作成分, 但不能省略)

The order that we received yesterday was that we should send a few people to help the other groups.

我们昨天收到的命令是我们应该派几个
人去帮助别的几个小组。

(定语从句, 是名词order的修饰语, that
在从句中作received的宾语, 可以省略)

判断下列哪些含有同位语从句,哪些含有 定语从句。 1. The news that we had successfully sent up another communication satellite spread throughout the world. 同位语从句 2. That’s the best piece of news I’ve heard.
定语从句 3. I’ve no hope that my parents have been expecting to me. 定语从句

4. Is there any hope that he will be home at 7:30? 同位语从句 5. The possibility that you referred to doesn’t exist at all. 定语从句 6. The fact that we talked about is very important. 定语从句 7. There is a strong possibility that we may be in France for the next week. 同位语从句
