Step2 Exploring study
Ⅰ、定义和功能
在复合句中起名词作用的从句叫名词从句 (Noun Clauses)。名词从句的功能相当于名词词组, 它在复合句中能担任主语、宾语、表语、同位语、介词宾语等，因此根据它在句中不同的语法功能，名词性从句又可分别称为主语从句、宾语从句、表语从句和同位语从句。
1. 主语： What he studies is important.
2. 表语： This is what he studies every day.
3. 宾语： I don’t like what he studies every day.
4. 同位语：I don’t know about the fact that he studies French every day.
II. 名词性从句的语序
1. 名词性从句的构成有两种
That + 陈述句
That light travels faster than sound is known to all.
疑问词+句子的剩余成分
This is what he is looking for.
2. 疑问词引导的名词性从句要求使用陈述句语序。
How he was became a actor is still a puzzle.
Could you tell me where he lives?
III. 名词性从句连接词的选用
1. that 和what 的用法
that 和 what 都可引导所有的名词从句。that在名词性从句中不充当任何成分，只起连接作用。 what 除了起连接作用外，还在名词性从句中充当成分，可做从句的主语、宾语、或表语。
Practice
1) ______ he wants is a car.
2) _______ he wants to go there is obvious.
3) The result is _____ we won the battle.
4) Is _____ he told us true ?
2. 不能使用if 的情况：
1)主语从句, 表语从句, 同位语从句以及介词后的宾语从句
2) whether or not连在一起引导宾语从句时不用if.
Practice
1) I asked her __________ she had a car. （if / whether）
2) ________ we will hold a party in the open air next Sunday depends on the weather.（Whether）
3) We’re worried about ________ he is safe.（Whether）
4) I don’t know ___________ he is well or not.（if / whether）
5) The question is ________ he should do it.（Whether）
6) The doctor can hardly answer the question ________ the old man will recover soon.（Whether）
3. 其它连接代词和副词的用法
主要根据名词性从句中的具体意义, 正确的选择who， which， when，where， why， how 等连接词，这些连接词既具有疑问词含义，又起连接作用，同时在从句中充当各种成分。
Practice
1) ______ we shall hold our sports meet is not decided.
2) I don’t know _____ broke the window yesterday.
3) I have no idea ______ he has a car.
4) This is ______ I left my coat.
4. that 的省略与不省略
单个宾语从句中的that可省略。
that不可省略的情况：
1）主语从句 2）表语从句 3） 同位语从句4）用it做形式宾语的宾语从句 5）并列的宾语从句中的后几个从句的引导词that 不能省略
Practice
1) I don’t think _____ he is coming.(that可省)
2) It is a pity ____ she has made such a mistake.（that 不可省）
3) The reason is ____she is careless.（that 不可省）
4) The news _____ our team won the game inspired us.（that 不可省）
5) I don’t think it necessary _____you should read English aloud.（that 不可省）
6) He told me _____ his parents had died （that 可省） and ____ he had to make a living alone.（that 不可省）
IV、同位语从句的引导和辨别
1．同位语从句的格式：n. + 连接词 + 从句
2. 能接同位语从句的名词有：fact、idea, news, information, order, belief, suggestion, advice等；
3. 连接词通常是that,也可根据含义选用 whether, what, when, where 等来引导同位语从句。
Practice
1) I have no idea _____ he comes from.
2) He can’t answer the question ____ he got the money.
3) He gave us some suggestions ____we should get up earlier and do more exercise.
4) I have no doubt ____he will recover.
5) I have some doubt ________ he will recover.
V. 宾语从句的时态呼应
1.如果主句时态是现在时或将来时, 从句谓语可根据句意需要而选用任一种时态。
He believes his dream will come true one day.
Please tell me what you were doing at this time last week.
2. 如果主句谓语是过去时, 从句谓语动词一般用过去的某种时态, 但从句表达的是客观事实、真理、自然规律等时，从句谓语通常用一般现在时。
He told me he was preparing for the final-term examination.
He told me he had been away from his hometown for many years.
The teacher told us light travels faster than sound.
