【点评】考查名词性从句，本题涉及that引导的宾语从句和what引导的主语从句。

3．It has been pointed out ________ plays a vital role in driving away one's anxiety is one's sweet childhood memories.

A. focused; whether

B. focused; if

C. has focused; whether

D. has focused; if

【答案】 C

【解析】【分析】考查时态和主语从句。根据In the past decade,在最近的几十年里，可知句子用现在完成时态，our education system是句子的主语，单数形式，所以第一空填has focused；第二空是主语从句做主语，if是否，不能引导主语从句，所以第二空填whether。故选C。

【点评】主语从句主要有三类：

1）（1）由连词that引导的主语从句:引导词that无含义,在句中不做成分,不可以省。例如：That you will win the medal seems unlikely.你想获得奖牌看起来是不可能的。（2）用连词whether 引导的主语从句:whether有含义（是否）,在句中不做成分,不可以省。例如：

Whether she is coming or not doesn't matter too much.她来不来都无关紧要。注意：if不能引导主语从句。

2）用连接代词引导的主语从句（在由连接代词who, whose, whom, which, what, whoever, whomever, whichever, whatever引导的名词性从句中，其连接代词在句中起名词性作用，担当一定成分）.例如：What you need is more practice.你所需要的是更多的训练。

英语名词性从句知识归纳

名词性从句知识归纳 名词性从句是指在句子中相当于名词的从句，主要包括主语从句、宾语从句、表语从句和同位语从句。名词性从句不是修饰性从句，而是复合句中的主干。 e.g. That the boy failed again in the exam disappointed his mother. （主语从句） I know that he is writing his composition in his room. （宾语从句） The question is how we can finish it on time. （表语从句） The fact that some Chinese are still poor is really a great problem. （同位语从句） 一、宾语从句---及物动词、介词、部分形容词（certain, sure, glad, afraid, frightened, happy, pleased, sad, sorry, surprised, upset, satisfied等）后 e.g. I believe (that) he is honest. (that不充当从句内的任何成分，一般情况可省略) I’m glad that you are satisfied with your job. (that不充当从句内的任何成分) He doesn’t care if/whether it isn’t a fine day. (if/whether不充当从句内的任何成分) Please tell me what you want. (what充当从句内的宾语) She always thinks of how she can work well. (how充当从句内的状语) I don’t believe whatever he said.(whatever充当从句内的宾语，意为“任何事”) I’ll take whoever wants to go. (whoever从当从句内的主语，意为“任何人”)【宾语从句要点拓展】1. that引导宾语从句时一般可以省略，若由and或or连接两个宾语从句时，第一个从句中的that可以省略，而第二个分句前的that不可省略。 e.g. He told me (that) they could not decide what to do and that they asked my advice. 2. whether和if引导宾语从句一般可以互换使用，但以下情况只能使用whether

(完整版)高一英语(牛津译林版)定语从句

定语从句 一、基本概念 1．定语从句：在一个主从复合句中修饰某一个名词、代词或修饰整个主句的从句叫定语从句。换句话说，定语从句就是用来作定语的句子。 2．先行词：被定语从句修饰的名词或代词叫先行词。先行词前一般用the ，但在指“一个”概念时可用a , an 。 3．关系代词/ 关系副词：连接先行词和定语从句的词叫关系词，根据其在从句中作用分为关系代词或关系副词。若先行词在从句中作主语、宾语和定语等，应用关系代词引导定语从句；若先行词在从句中作时间状语、地点状语和原因状语等，应用关系副词引导定语从句。 4．定语从句的位置：一般紧跟在先行词后面。但有时因句子结构的需要，定语从句和先行词被某些成分隔开。 5．引导定语从句的关系词分为二类： 关系代词：that, which ,who, whom ,whose , as 关系副词：when, where, why 二、基本用法

2．使用关系代词时应注意的几个问题： a. 在以下几种情况下只使用that不用which。 1.先行词是不定代词时，如: all, anything, everything, nothing, something, little, few, much。 1.I told him all (that) I know. 2.He gave her everything (that) he had. 2.先行词被all, every, any, the very, the only, the just等修饰时。 1.I have read all the books (that) you gave me. 2.You can take any book (that) you like. 3.先行词被序数词和形容词的最高级修饰时。 1. This is the best book (that) I have ever read. 2.

经典英语名词性从句

名词性从句在复合句中具有名词的性质的作主语、表语、同位语、宾语的从句叫名词性从句。因此，我们把主语从句、表语从句、同位语从句和宾语从句这四种从句统称为名词性从句。 主语从句(subject clauses)在复合句中起主语作用的从句叫主语从句。引导主语从句的词有从属连词、、关系代词、连接副词等。引导主语从句的关联词有从属连词that、whether，关系代词：who, what, which, whom, whose, whatever, whoever, whomever, whichever；关系副词：when, where, how, why, however, whenever, wherever等。 That you don’t like him is none of my business.你不喜欢她不管我的事。 What he said is true. 他说的是真的。 Do you remember how he arrived almost at the end of the party?你记得他几乎是在宴会快结束时才到的吗？ This party's really where it's at, man! 啊，这个晚会真棒！Tell us how you fulfilled the heavy task ahead of schedule.告诉我们,你们是怎样提前完成这一艰巨任务的。 We have reason to believe that the fighting on the border may develop into a full-blown war. (喻)我们有理由相信边境上的冲突可能发展成一场全面战争。 He said that he would come. 他说他要来。

I have no idea what he did that afternoon. 一．主语从句：在复合句中作主句的主语。 ●__________ he is a famous singer is known to us. ●__________ he will go to America is not yet fixed. ●__________ she’s coming or not doesn’t matter too much. ●__________ broke the glass yesterday is not clear. 【keys】That; When/How; Whether; Who 【归纳】 1.为避免主语冗长,句子头重脚轻, 经常用it作形式主语, 主语从句放在后面作真正的主语。 例：That her hair was turning gray worried her a lot. -----It worried her a lot that her hair was turning gray. 常考句型： It’s likely / possible / important / necessary / clear that…
