高中英语从句总复习
| |
||
I walked over to where she sat.我走向她坐的地方。
I am curious as to what he will say.我很想知道他要说什么。
Your success will largely depend upon what you do and how you do it.
你是否成功将主要取决于你做什么和怎样做。
有时介词可以省略。如:
I don’t care (for)who marries him.我不管谁跟他结婚。
Be careful (as to)how you do that.你要注意做这件事的方式。
解释:
1.如果宾语从句后还有宾语补足语,则用it作形式宾语,而将宾语从句后置。如:
We thought it strange that Xiao Wang did not come yesterday.
我们认为小王昨天没来是奇怪的。
He has made it clear that he will not give in.
他已表明他不会屈服。
2.作介词的宾语:连词that引导的名词性从句很少作介词的宾语,只用在except,but,in后。其他一些介词的宾语从句如果由连词that引导,则需用it先行一步,作形式宾语。如:
He is a good student except that he is careless.
他是一个好学生,只是有点粗心。
You may rely on it that I shall help you.你可以指望我会帮助你的。
介词宾语不可以用which来引导,而要用what来引导。如:
Are you sorry for what you’ve done?
你为你所做的一切感到内疚吗?
3.某些形容词或过去分词后常接宾语从句,这类形容词或过去分词有sure,glad,certain,pleased,happy,afraid,surprised,satisfied等,连词that可省略。如:
I am not sure what I ought to do.
我不能确定我该做什么。
I’m afraid you don’t understand what I said.
恐怕你没领会我说的意思。
I’m surprised that I didn’t see all that before.
我好奇怪,我以前没看到过。
Mother was very pleased her daughter had passed the exams.
妈妈为她的女儿通过了考试而感到高兴。
4.连词whether (…or not)或if引导的宾语从句
if和whether引导的宾语从句可以互换使用,但whether常和or not连用,if一般不与or not连用。如:
I wonder whether it is true or not.我不知它是真是假。
用if引导宾语从句如果会引起歧义,应避免使用if而用wheter.试比较:
Please let me know if you want to go.
Please let me know whether you want to go.
if从句可理解为宾语从句,意为“请告诉我你是否想去”;此句又可理解为条件状语从句意为“如果你想去的话,请告诉我一声”。
5.宾语从句的否定转移。在think,believe,suppose,expect等动词后的宾语从句,有时谓语尽管是否定意思,却不用否定形式,而将think等动词变为否定形式。如:
I don’t think you are right.我认为你错了。
I don’t believe they have finished their work yet.我相信他们还未完成他们的工作。
I don’t suppose he cares,does he? 我想他不在意,是吗?
6.宾语从句的时态变化规律:
(1)当主句是一般现在时态时,从句可根据需要用任何时态。
(2)当主句是一般过去时态时,从句只能使用过去范围内的任何时态。但客观真理除外。如:
The teacher said that the earth goes round the sun.
老师说地球绕着太阳运行。
4)同位语从句
1.定义:用作同位语的从句叫做同位语从句。
2.用法:同位语从句的先行词多为fact,news,idea,thought,question,reply,report,remark等,关联词多用从属连词that.如:
They were all very much worried over the fact that you were sick.
对你生病这件事,他们都很焦虑。
Where did you get the idea that I could not come?
你在哪儿听说我不能来?
Early in the day came the news that Germany had declared war on Russia.
德国已对俄国宣战的消息一大早就传来了。
注:同位语从句偶尔由从属连词whether引导。如:
I have no idea whether he’ll come or not.我不知道他是否来。
连接代词who,which,what和连接副词where,when,why,how亦可引导同位语从句。
The question who should do the work requires consideration.
谁该干这项工作,这个问题需要考虑。
