预习中的问题
教学过程：
一．名词性从句的构成：在句子中起名词作用的从句称为名词性从句：它包括主语从句，宾语从句，表语从句和同位语从句，由连词that,if/whether和各种特殊疑问词引导。
注意：这类从句主谓语必须用陈述语序。
二．名词性从句用法
1.主语从句：在复合句中充当主语的从句。
(1)由that引导的主语从句（that不可以省略）
That the doorman remembered their names surprised them a lot.
有人还记得他们的名字使他们感到很惊讶。
(2)由whether引导的主语从句（不可用if代替）
Whether it will clear up tomorrow is not yet known.明天天气是否会放晴尚不清楚。
(3)由特殊疑问词引导的主语从句
How much time students spend on their homework often concerns teachers.
教师们经常关心学生花多少时间完成作业。
(4)it作形式主语（that不可以省略）
_________________________ the football team was warmly received by the Queen at the Buckingham Palace. 据报道，足球队在白金汉宫受到了女王的亲切接见。
2.宾语从句：在复合句中作宾语的从句，通常放在主句的谓语动词(及物动词)或介词之后。
(1)作动词的宾语
a.由that引导的宾语从句（that在非正式语体中通常可以省略）
Later on I realized (that) I was wrong.
b.由whether/if引导的宾语从句
I wonder whether/if you can change this 50-yuan note for me.
c.由特殊疑问词引导的宾语从句
She didn’t know where she could find the Students’ Union.
(2)作介词的宾语
We talked excitedly about whether we would spend our two-day holiday on the beach or in the swimming pool.
注意：介词后面的宾语从句用whether引导，而不用if。
(3)it作形式宾语
I find it interesting that traffic always keeps to the left in Britain.
使用宾语从句时要注意：
(1)时态呼应：当主句谓语动词是过去时态，宾语从句要使用过去时态的某种形式。
(2)注意否定前移：当主句是 I/We think（或suppose, expect, believe, imagine, guess）
其后的宾语从句如果是否定的，常常把否定词not 从从句移到主句。
3.表语从句：在复合句中作表语的从句，放在系动词之后
(1)由that引导的表语从句（that在非正式语体中通常可以省略）
The fact is (that) we don’t have enough experience for the work.
(2)由whether引导的表语从句(不可用if代替)
The question is whether I should e-mail him about the news now.
(3)由特殊疑问句引导的表语从句
The problem we are facing now is how we can collect so much money for the blind.
4.同位语从句：在复合句中作名词的同位语的从句，它对名词起进一步解释的作用，说明名词所包含的具体内容,that不可省略.
Before leaving, the Green family expressed the hope that they would come to China again.
同位语从句一般跟在某些抽象概念的名词后面，用以说明名词所表示的具体内容。常跟同位语从句的名词主要有：idea, news, fact, promise, answer, belief, doubt, hope, problem, proof, question, suggestion, thought, truth, possibility等。
三、名词性从句中连接词用法的注意事项
1.that:非正式文体中，引导宾语从句的连词that常可以省去。但若宾语由两个并列句组成时，that不省略，并且每个并列句前都需要有that引导。
He said ________ he was running a fever and _______ he couldn’t come to school.
2.whether/if：在下列情况下，只能用whether而不用if:
(1)与or not连用时用whether 没人知道商店是否要关闭。___________________________
(2)介词或discuss后的宾语从句用whether，不用if
(3)表语从句用whether不用if，意为“是否” The question is whether we can get there.
(4)同位语从句中，表“是否”讲用whether而不用if
There is some doubt ________ he is the best man for the job.
四、关于名词性从句的补充说明
1.if在宾语从句与状语从句中的区别：宾语从句中，if和whether的意思基本一样，都表示“是否”，且从句中可用各种时态（包括将来时）；在状语从句中，if的意思是“假如”，表示将来的动作或者状态时，从句用一般现在时。
Please let me know if/whether you’ll join us tonight. ____________从句
If you plan to join us tonight,please let me know.______________ 从句
2.定语从句与同位语从句的区别：定语从句中的that既指代先行词，又在从句中作某个成分（主语，宾语或表语），作宾语时常可省略；而同位语从句中的that只起连接词的作用，不在名词从句中充当任何成分，且不可省略。
The news (that/which) he told us was exciting. 定语从句
that/which在句中充当定语从句中的宾语成分，指代先行词news，可省略。
The news that our volleyball team won was exciting. 同位语从句
从句说明news的内容，用that连接且不可省略。
3.表语从句的常用结构
(1) The reason (why)… is that意为“发生某种情况的原因是……”
The reason __________ I’m late is that I had a flat tyre.
注意：句中引导表语从句的连接词应该用that而不用because。
(2)That is where/when/how/why…表示“这就是……的地方/时间/方式/原因。”
I had a flat tyre. That’s____________ I was late for the meeting today.
