that引导的宾语从句(重难点)
宾语从句是指一个句子充当宾语,在主句与从句之间有一个引导词。
今天,我们就谈谈连接词that引导的宾语从句。
请同学们关注以下几点:
一、引导词本身的省略与不省略
1.可以省略
连词that引导宾语从句,只起连接主、从句的作用,它本身无意义,在口语或非正式文体中常省略。
如:
He says(that)he is a Young Pioneer.他说他是个少先队员。
2.不可以省略
(1)从句的主语是that时,that不省略。
如:
We know that that is an interesting story.我们知道那是一个有趣的故事。
(2)that引导的宾语从句中若再有复合句时,that不能省略。
如:
I think that if you have lost the library book,you must pay for it.我认为如果你已把图书馆藏书丢失了,你就必须赔偿。
(3)主、从句之间有插入语时, that不能省略。
如:
It says here,in the newspaper, that English is getting more and more important.报纸上写着,英语正变得越来越重要。
二、何时使用that引导的宾语从句
that引导的宾语从句,表示陈述一件事,即由陈述句转化而来。
如:
He says.He is listening to the weather report.→
He says(that)he is listening to the weather report.他说他正在听天气预报。
1.主句的谓语动词是think,hear, hope,wish,remember,forget,know,say, guess等时,常接that引导的宾语从句。
如:
I hope(that)he will be fine soon.我希望他很快好起来。
2.主句由“连系动词+形容词”构成的“系表”结构,常接that引导的宾语从句。
这类形容词多表示感情,如happy, glad,pleased,sad,sure,afraid等等。
如:
I'm afraid(that)he can't come.恐怕他不能来了。
三、that引导的宾语从句相关的内容
1.语序
不论什么情况下,宾语从句都要用陈述语序,即“主语+谓语+其它”。
如:Do you think?The radio is too noisy.(合并成主从句)→
Do you think(that)the radio is too noisy?你认为收音机太吵吗?2.时态
that引导的宾语从句,主句用一般现在时,从句可以用符合句意要求的任一时态。
如:
He says(that)they have returned already.他说他们已经回来了。
He tells me that he was born in 1985.他告诉我他生于1985年。
如果主句用一般过去时,从句要用过去时态的某种形式(一般过去时,过去进行时,过去将来时,过去完成时)。
如:
He said(that)he bought a new dictionary.他说他买了本新词典。
I knew they were studying English.我知道他们正在学英语。
注:如果从句表达的是客观事实、真理、自然现象、名言、警句、格言、谚语等等,尽管主句用一般过去时,从句也要用一般现在时。
如:
Our teacher told us that light travels faster than sound.我们老师告诉我们,光比声音传播得快。
He said that time is life.他说时间就是生命。
