2013高考英语：表语从句（专题复习）
1、在句中作表语的从句叫表语从句。引导表语从句的关联词与引导主语从句的关联词大致一样，表语从句位于连系动词后，有时用as if引导。其基本结构为：主语 + 系动词 + that从句。例如：
The fact is that we have lost the game. 事实是我们已经输了这场比赛。
That’s what I want. 这正是我想要的。
This is where our problem lies. 这就是我们的问题所在。(表语从句一定要用陈述语序) That is why he didn’t come to the meeting. 那就是他为什么不到会的原因。
It looks as if it is going to rain. 看上去天要下雨了。
四、同位语从句
1、同位语部分是个句子,就是同位语从句。同位语从句是用来说明其前面的名词的具体内容。同位语从句通常由that引导，可用于同位语从句的名词有fact，news，idea, truth , question，hope，promise，suggestion，thought，order，problem，belief，doubt，fear，possibility等。例如：
The news that we won the game is exciting. 我们赢得这场比赛的消息令人激动。
I have no idea when he will come back home. 我不知道他什么时候回来。
The thought came to him that Mary had probably fallen ill. 他想到可能玛丽生病了。
同位语从句和定语从句的区别：
定语从句：用来修饰其前面的名词，关系词、代词、名词在句中作成分；
同位语从句：用来说明其前面的名词的内容，引导词在从句中不作成分。
试比较下面两个例句:
1.The news (that/which) I heard is true.(定语从句)
The news that our team won the game is true.(同位语从句)
2.The suggestion that he put forward was turned down.
He put forward the suggestion that the meeting (should) be put off.

1. ___ is a fact that English is being accepted as an international language. (NMET 1995) A. There B. This C. That D. It
答案D。当名词从句在句中作主语时，为避免句子头重脚轻，常用it作形式主语置于句首，而将真正的主语从句放在句尾。此时it只起先行引导作用，本身无实义。此句也可以改写为：That English is being accepted as an international language is a fact.
2．A computer can only do ____ you have instructed it to do．（NMET2001）
A．how B．after C．what D．when
答案C。从句子结构可知，句子的空白处应该填引导宾语从句的连词，做主句谓语动词do的宾语，同时该连接词还是从句中的do的宾语，因此，此处的连接词应该用what。
3. He asked ____ for a violin．（MET1992）
A. did I pay how much B. I paid how much C. how much did I pay D. how much I paid
答案：D。宾语从句相当于特殊疑问句，句子语序要用陈述语序。
4. What the doctors really doubt is ____ my mother will recover from the serious disease soon．（上海2001年春季招生）
A. when B. how C. whether D. why
答案C。这是一个表语从句。根据 doubt一词可知，所怀疑的应是是否能治好病，所以要填whether。这句话的意思是“医生真的怀疑我妈妈是否能很快从重病中恢复过来。”
5. ______leaves the room last ought to turn off the lights. (MET1988)
A. Anyone B. The person C. Whoever D. Who
答案C。本题句子的意思是：无论谁最后离开房间一定要把灯关掉。本题考查连接代词whoever引导的名词性从句，连接代词whoever可以引导名词性从句，并在从句中作主语，相当于any person who或The person who, 意为“一切……的人”。而anyone和the person均非连词，不能引导从句，况who leaves the room last意为“某个最后离开房间的人”，与题意不符，如果要选A. Anyone或B. The person，都必须在它们后面再加上引导定语从句的关系代
词who。如果要选D. Who就体现不出“无论谁”的含义了。
6. ‐‐‐‐ I drove to Zhuhai for the air show last week.
‐‐‐‐ Is that ______ you had a few days off ? ( NMET1999)
A. why B. what C. when D. where
答案A。根据语境，甲说上周驱车去珠海观看航模展览。乙据此来询问甲这是否是请几天假的原因，故答案是A。
7. I still remember ______ this used to be a quiet village. ( NMET1993)
A. when B. how C. where D. what
答案A。根据从句中缺少的句子成分是状语，排除D．what，而答案B, C均与题意不符，所以应选A．when。本句的意思是“我仍然记得这里在什么时候是个宁静的地方。”
8. —I think it is going to be a big problem. —Yes, it could be.
—I wonder ______ we can do about it. (北京 2002春季)
A、if B、how C、what D、that
答案C。本题考察名词性从句的连接词的用法。wonder后面应跟宾语从句，而从句中的谓语动词do是及物动词，可见从句缺少一个代替宾语的成分，我们可以用排除法排除不作成分的if和that，再排除引导方式状语的how，答案是C，句子的意思是“我们能就此做些什么”。
