【名师点睛，易错起源】
易错起源1、名词性从句中连接词的正确选用
例1．(2015·福建)—I wonder
Mary has kept her figure after all these years.
—By working out every day.
【变式探究】He can’t answer the question
hegot the money.
A. what
B. that
C. how
D. where
【名师点睛】
1.that引导名词性从句时，在从句中无意义，不作成分，只起到连接作用，在宾语从句中可省略。
He told me (that) he would leave soon.
2.what与出at在名词性从句中的区别。
Right:What he said was true.
这是一个主语从句，what在从句中作动词said的宾词，意思是:“……话”或“……事”，此句中不能用that。
That he came late made the teacher angry.
这个句子还是主语从句。从句中意思完整，所以用that来引导，起到一个标志作用。
易错起源2、宾语从句
例2．(2015·湖南)You have to know
you're going if you are to plan the best way of getting there.
【变式探究】We find __ necessary __ we practise English every day.
A. it;/
B. it;that
C. it’s;/
D. it’s;that
【名师点睛】
1.出at引导的宾语从句出at常用来引导宾语从句，通常that可以省略。
He has told me that he will go to Shanghaitomorrow．他已经告诉我他明天要去上海。
注意：在demand，order，suggest，decide等表示要求、命令、建议、决定等意义的动词后,hat从句常用“(should)+动词原形”的结构。
2.wh-引导的宾语从句
I want to know what he has told you．我想知道他告诉了你什么。
【锦囊妙计，战胜自我】
形容词后所跟的宾语从句
某些动态形容词(afraid，confident，aware，certain，sure，doubtful等)在句中做表语时，后面可跟宾语从句。
例句:I am confident that I can get the job．我有信心我可以得到这份工作。
易错起源3、 that和wh-引导的主语从句
例3．2015·北京)I truly believe
beauty comes from within.
【变式探究】After Yany Liwei succeeded in circling the earth,
our astronauts desire to do is walk in space.
A. where
B. what
C. that
D. how
【名师点睛】
(1)that引导的主语从句
that引导的主语从句既可以放在句首也可以放在句末，在实际应用中常常采用it形式主语形式。
That he passed the English test is true.→
It is true that he passed the English test.
(2)形式主语的四个主要句型
It + be + 名词 + that从句
It is a pity that...可惜的是，用于此句型的名词还有fact／shame／honor／question等。
It + be + 形容词 + that从句
It is certain that...很肯定，可用于此句型的形容词还有clear／better／natural／important／neeessary.
It + be + 动词的过去分词 + that从句
It is said that...据说，可用于此句型的过去分词还有believed／known／reported等。
It + 不及物动词 + that从句
如: It seems that...好像是……似乎……
可用于此句型的不及物动词还有happen，appear等。
易错起源4、 表语从句、同位语从句
例4．(2015·安徽)A ship in harbor is safe, but that's not
ships are built for.
【变式探究】 A stroy goes __ Elizabeth I of England liked nothing more than being
surrounded by clever and qualified noblemen at court.
A. when
B. where
C. what
D. that
【名师点睛】
1.that引导的表语从句
基本结构:主语 + 系动词 + that从句例句:
The fact is that we have lost the game.
2.wh-疑问词引导的表语从句
That is why I tell you the news.那就是我为什么告诉你这个消息的原因。
3.从属连词as if,boecause,just as等引导的表语从句
It is because I have ever heard of the story.那是因为我曾经听说过这个故事。
【锦囊妙计，战胜自我】
同位语从句通常由that引导，可用于同位语从句的名词有advice，demand，doubt，fact，hope，idea， information，message，news，order，problem，promise， question，repuest，suggestion，truth，wish，word等。
