[考 点 清 单]

考点一　主语从句

规则❶ 引导主语从句的连接词如下： who，that，which，what，when，where，how，whether，why，whoever，whichever，whatever等。

That you are coming to London is the best news I have heard this long time.

长久以来我听到的最好的消息就是你要来伦敦。

What struck me most in the movie was the father's deep love for his son.

影片中最打动我的是父亲对他儿子深深的爱。

规则❷ 主语从句一般放在句首，但有时也可用it作形式主语，而将主语从句移到句子的末尾。常见的句型：

(1)It＋be＋形容词(necessary/likely/important/uncertain等)＋that从句。

It is uncertain what side effect the medicine will bring about，although about two thousand patients have taken it.尽管大约两千名患者已经服用了这种药，但是它会带来什么样的副作用还不清楚。

(2)It＋be＋名词(短语)(a pity/a shame/no wonder/no surprise等)＋that从句。

It's no surprise that our team has won the game.

我们队获胜一点都不令人吃惊。

(3)It＋be＋过去分词(said/reported/decided/believed等)＋that从句。

It is decided that the meeting has been put off till next Monday.会议被推迟到下周一召开已经定下来了。

考点二　表语从句

规则❶ 表语从句的引导词主要有： that(不可省略)，whether(不能换成if)，what，who，which，how，why，when，where，whoever，wherever，as if/though等。

The question is whether we can make good preparation in such a short time.

问题是我们是否可以在如此短的时间内做好准备。

规则❷ because引导的表语从句强调原因，而why引导的表语从句强调结果。

If I'm a bit sleepy，it's because I was up all night.

如果我有点困，是因为一夜没睡。

That's why I object to the plan.

这就是我反对这个计划的原因。

考点三　宾语从句

规则❶ 引导宾语从句的连接词：从属连词that，whether，if；连接代词what，who，whose，whatever，whichever，whoever等；连接副词when，where，why，how等；从句用陈述语序。

We must find out when Karl is coming，so we can book a room for him.我们必须弄清楚卡尔什么时候来，以便我们可以为他预订房间。

规则❷ 形式宾语it：在动词find，feel，consider，make，believe，think等后面有宾语补足语的时候则需要用it作形式宾语而将that宾语从句后置。

I made it clear that I was determined to carry out the plan.我很清楚，我已下定决心实施这项计划。

规则❸ 有些动词不能直接跟宾语从句，需要借助形式宾语it。常见的这类动词有like，dislike，hate，love，enjoy，appreciate等。

He hates it when people play his iPhone 7.

他讨厌别人玩他的苹果7。

考点四　同位语从句

规则❶ 同位语从句常放在fact，news，idea，truth，hope，problem，information，belief等词的后面，对前面的名词作进一步解释、说明。

The problem whether we should continue to do the experiment hasn't been solved.

我们是否应该继续做实验这一问题还没解决。

规则❷ 同位语从句的引导词只起引导作用，不在句中作任何成分，一般不可省略。

The news that Sun Yang had won the game spread over the whole school.

孙杨赢得比赛的消息很快就传遍了整个学校。

考点五　whether/if(是否)引导的名词性从句

规则❶ whether和if在宾语从句中经常可以互换。但在引导主语从句、表语从句和同位语从句时一般用whether不用if。

规则❷ 但与or或or not连用时只能用whether。

I don't know whether or not the report is true.

我不知道报道是否真的。

规则❸ 但从句作介词宾语时只能用whether。

I worry about whether he can pass through the crisis of his illness.我担心他是否能熬过这次疾病的关键时刻。

[正 误 探 究]

1．【误】He got ill；this__was__why he had eaten too much.

【正】He got ill；this__was__because he had eaten too much.

【探究】this was because...那是因为……；this was why……那就是……的原因。

2．【误】For one thing，that you are studying is badly needed nowadays in our country.

【正】For one thing，what you are studying is badly needed nowadays in our country.

【探究】what在名词性从句中可作主语、宾语或表语；而that本身没有意义，不作任何成分，只起连接作用。

3．【误】Our__team__won__the__match pleased us very much.

【正】That__our__team__won__the__match pleased us very much.

【探究】that引导主语从句时虽然只起引导作用，但通常不能省略。

4．【误】If you can make progress in your study depends on whether you try your best.

【正】Whether you can make progress in your study depends on whether you try your best.

【探究】if引导主语从句不能放在句首，这时要用whether。

[易 错 防 范]

易错点1　what与that在名词性从句中的区别

(1)________ I want to tell you is the deep love and respect I have for my parents.

误填　That

答案　What　[本题考查主语从句。句意：我想对你说的是我对父母亲的深深的爱和尊重。句子谓语为is，之前为主语从句，从句中缺少动词tell的直接宾语，指事物，故填what。]

(2)Experts believe ________ people can waste less food by shopping only when it is necessary.(2013·北京，33)

误填　what

答案　that　[本题考查宾语从句。句意：专家们相信人们只在必需的时候购物就会浪费更少的食物。动词believe之后为宾语从句，从句陈述一个事实，结构完整，不缺少成分，故用that。]

【点拨】that在其引导的名词性从句中只起引导作用，不作句子成分；而what在名词性从句中起双重作用，既作成分，又能引导句子。故做题的关键在于分析从句中是否缺少成分。即在that/what之间，若从句缺成分就选what，反之that。

易错点2　whatever与what；whoever与who的区别

(1)We promise ________ attends the party a chance to have a photo taken with the movie star.(2012·福建，35)

误填　who

答案　whoever　[考查宾语从句的连接词。句意：我们允诺向任何参加聚会的人提供一个和那位电影明星合影的机会。参加聚会的任何人whoever相当于anyone who，whoever引导的从句作promise的宾语，同时whoever又在从句中充当主语。]

(2)The newcomer went to the library the other day and searched for ________ he could find about Mark Twain.(2012·辽宁，34)

误填　what

答案　whatever　[考查宾语从句。介词for后面加的是宾语从句，且从句中find缺少宾语，所以用whatever。]

【点拨】在名词性从句中，引导词whatever，whoever均泛指，分别可转换成anything that，anyone who，并将其代入，这样解题便轻松多了。

易错点3　名词性从句与其他从句混淆不清

We're living in ________ people call “Information Age”，so everything is possible.

误填　which

答案　what　[句意：我们生活在信息时代，所以一切皆有可能。介词in后跟宾语从句。在从句中动词call后缺宾语，故用what。]

【点拨】弄清连接代词与连接副词的区别。关系代词who，whose，whom，that，which有词义，在从句中作主语、表语、宾语或定语等。when，where，why，how有词义，在从句中作状语。that无词义，不作成分。if/whether有词义，在名词性从句中不作成分。
