2. Learning about grammar
Introduction to Noun Clauses
A noun clause is a clause which does the work of a noun in a sentence. It is a group of words containing a subject and a verb of its own. It can be used as a subject, predicate nominative, direct object, appositive, indirect object, or object of the preposition.
Usually noun clauses begin with that, what, where, when, who, whom, which, whose, how, why, whether, etc.
Examples:
·He said that he would not come.
·We were all curious to know what he had done.
·Nobody knows when the registration will begin.
·We all wanted to find out who the winner was.
·Whom they were in contact with on the day of the robbery is of great interest to the police.
·Jane is not sure which university she should apply for.
·The judges had a hard time deciding whose painting was the best.
·How the baby fell from the window is a mystery.
·They asked the boy why he had hit his classmate.
·Whether you like it or not is not the issue.
Uses of Noun Clauses
Noun Clauses can be used in the following ways:
Find the noun clauses in the following sentences and tell how they are used. (Subject, predicate nominative, direct object, appositive, indirect object, or object of the preposition)
1. How the prisoner escaped is a mystery.
2. My feeling is that the robbery was an inside job.
3. Everyone is wondering how he could just disappear.
4. The news that he had escaped frightened the whole town.
5. The police have offered whoever finds the stolen diamonds a reward.
6. The family has had no word about where he might be.
7. That we were ready to go was a miracle.
8. Give whoever wants to go a ride to the game.
9. That you are losing ground was evident from the polls.
10. Whoever injured the handicapped woman must be feeling guilty.
3. 学习主语从句
一、由what（whatever，whoever）等代词引导的主语从句。
What they are after is money. 他们追求的是金钱。
Whatever was said here must be kept secret. 这里说的话都应当保密。
二、由连词that引导的主语从句。其中that一般不可省略，但若用it作形式主语， that从句后置时，则可省略。为避免头重脚轻，我们倾向用it开头，后接be，seem等。如果句子是疑问形式，就只能用带it的结构。
That money doesn't grow on trees should be obvious.
金钱不能从树上长出来是显而易见的。
It is obvious（that）money doesn't grow on trees .显而易见，金钱是不能从树上长出来的。
Has it been announced when the planes are to take off？飞机什么时候起飞宣布了没有？
注意：
1）选用what还是用that引导主语从句要根据关联词在从句中是否担任成分而定。且what（以及whatever，whoever等）引导的主语从句一般不用it作形式主语。
What he said is true.他说的是真的。（what在其引导的主语从句中作宾语。）
That China is a great socialist country is well known.（=It’s well known that…）众所周知，中国是一个伟大的社会主义国家。（that在其引导的主语从句中不作任何成分，也无词义，只起连接作用。）
2）it引导的强调句与it作形式主语的复合句不可混淆。it引导的强调句是用来对句中某一成分加以强调，其结构为：“It is（或was）+强调部分+that（或who）…”强调句去掉It is（或was）…that（或who）…框架后，剩余部分为一个完整的句子。
It was I that(who) met Mary in the street yesterday.是我昨天在街上遇见了玛丽。(强调主语)
3）常见的用it作形式主语的复合句结构：
*It is+形容词（necessary，strange，important，wonderful，possible，likely，等）+that从句，从句中常用虚拟语气。
It’s necessary that he write something in English.他用英语写点东西是必要的。
It’s strange that she did not go to school yesterday.奇怪的是她昨天没去上学。
*It is+名词（a fact，a pity ，no wonder，good news，等）+that从句
It's a pity that she should have said so.真遗憾她竟然会这么说。
*It is+过去分词（said，reported，decided，unknown等）+that从句
Its said that our English teacher will go abroad next week.据说我们英语老师下周要去出国。
*It +不及物动词（seems，appears，happens， matters等）+that从句
It seems that she is in great need of help.看来她急帮忙。
4）主语为从句时，一般要用单数谓语动词形式；但如果引导的从句作主语、代表复数概念（常可从表语上看出）时，谓语动词则常用复数形式：
What we need is water. 我们需要的是水。
What we need are useful books. 我们需要的是有用的书。
三、由连接代词或连接副词（或if, whether）引导的主语从句。
When they will come hasn't been made public.他们什么时候回来还没有宣布。
Whether I’ll attend the meeting hasn’t been decided.=It hasn’t been decided whether(if) I’ll attend the meeting.我是否参加会议还未决定。
