考点一引导名词性从句的连接词１．连接代词who,whose,whom,what,which及wh—ever等它们有词义,在从句中作成分。
what∕whatever指物,作主语、宾语、定语、表语;who∕whoever指人,在从句中作主语、宾语;whom∕whomever指人,在从句中作宾语;whose在从句中作定语;which∕whichever指人或物,在从句中作定语、主语、宾语。
带—ever的连接词意义上有“任何……”之意。
What I want to know is the price of the bike.我想知道的就是自行车的价格。
You can buy whatever you need in the shop.在这家商店你能买到任何你需要的东西。
whoever,whatever,wherever...等引导的从句不仅是句子的语气加强了,而且此类词引导的句子表示让步和泛指的概念,而who,what,where...等引导的句子表示具体的概念。
如:What he said is right.他所说的是对的。
（特指他这次所说的事情）Whatever he said is right.无论他说什么都是对的。
此处,whatever= anything what,表示泛指和让步,意为“无论他说什么”。
Who will do it is not decideＤ．谁去做这件事还没有确定。
（指一次具体的动作）Whoever does it will be punisheＤ．无论谁做了这件事,都要受到惩罚。
（此处特别强调“无论是谁”）wh—ever这类词引导名词性从句时,不能用no matter+who∕what∕which...代替。
它们有词义,在句中作状语。
when表时间,why表原因,where表地点,how表方式、程度。
This is why I came here.这是我来这儿的原因。
I have no idea where he went.我不知道他去了哪里。

1.that引导主语从句that引导主语从句时不同于其他的连词，既无词义也不作成分，只起单纯的连接作用，且通常不可以省。
为了强调that引导的主语从句而置之于句首时，that不可省。
①That the driver could not control his car was obvious.②That she was chosen made us very happy.③That he will come is certain.④That he would take the risk is true.⑤That he should have married her isn't surprising.★通常，that引导主语从句时用it做形式主语，把从句置于句尾，此时that 有时可省。
例如：①It was obvious that the driver could not control his car.②It made us very happy that she was chosen.③It is certain that he will come.④It is true that he would take the risk.⑤It isn't surprising (that) he should have married her.★如果以that从句为主语的句子是疑问句，就只能用先行词it结构。

②What 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。
2．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(2)It＋be＋名词(短语)(a pity/a shame/no wonder/no surprise等)＋that 从句(3)It＋be＋过去分词(said/reported/decided/believed等)＋that从句(4)It＋不及物动词(seem, appear, happen等)＋that从句①It 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。
②It’s no surprise that our team has won the game.我们队获胜一点都不令人吃惊。
③It is decided that the meeting will be put off till next Monday.会议被推迟到下周一召开已经定下来了。
二、宾语从句1．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。

2．it作形式宾语的宾语从句(1)一些动词后的宾语从句有宾语补足语时，则需要用it作形式宾语，而将that 引导的宾语从句后置。
常见的这类动词有：find, feel, think, consider, believe, guess, suppose, make等。
He has made it clear that the meeting will not be postponed.他清楚地表明会议不会被推迟。
(2)动词hate, like, dislike, appreciate, enjoy等表示“喜欢”、“厌恶”的动词以及一些动词短语see to, depend on, rely on等常用it作形式宾语，而将宾语从句后置。
I shall see to it that he is taken good care of when you are absent.你不在的时候，我会确保把他照顾好。
三、表语从句1．引导表语从句的连接词：从属连词that, whether；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。

2．as if/as though 引导的表语从句as if/as though 引导的表语从句常跟在be 动词，seem, look, taste, sound,feel, appear 等动词之后。

好像把一个巨大的黑色的毯子扔到它的上面。
3．because, why 引导的表语从句because, why 也可引导表语从句，但because 引导的表语从句，主语不能是reason 或cause (该结构常用that 引导)。
常用于以下句型：⎩⎨⎧ This/That is/was why ... 这/那是……的原因。
This/That is/was because ... 这/那是因为……The reason why ... is/was that ... ……的原因是……①China is developing fast. That ’s why I think those of my colleagueswho deal with China affairs should visit China. 中国在飞速发展，这就是我为什么认为我的那些跟中国打交道的同事应该访问中国。
②The reason why he didn ’t pass the exam was that he was too careless.他没有通过考试的原因是他太粗心了。
四、同位语从句同位语从句在句中作某一名词的同位语，位于该名词之后，用以说明该名词的具体内容。
1．常见的后跟同位语从句的名词有：would be different.我对自己承诺：今年，我高中的第一年，会有所不同。
②—Is there any possibility that you could pick me up at the airport?—No problem.——你有可能到机场接我吗？ ——没问题。
