三、精心点拨，启发引导
考点一“疑问词＋ ever”和“no matter＋疑问词”
1．“疑问词＋ever”可引导名词性从句，在从句中要充当一定的成分。还可引导让步状语从句。
Whoever breaks the rule must be punished.
However late he comes back，his wife will wait for him.
2．“no matter＋疑问词”只能引导让步状语从句。
No matter who breaks the rule，he must be punished.
考点二 that引导宾语从句时的省略
宾语从句中的连接词that通常可以省略，但在以下几种情况中that不能省略：
1．当从句前有插入语时，that不可省略。
We hope，on the contrary，that he will stay at home with us.
2．当一个句子有两个或多个并列宾语从句时，引导第二个和以后的宾语从句中的that不能省略。
He said he was wrong and that he would say sorry to me.
3．当that作介词宾语时，that不可省略。
The reason lies in that she works harder than the others.
4．由it作形式宾语时，that引导的宾语从句中，that不可省略。
I think it impossible that he can finish the task in such a short time.
考点三 it作形式主语的常见句型
1．It is＋名词(no wonder，an honor，a good thing，a pity，no surprise等)＋从句。
It is no surprise that we will win the match.
2．It is＋形容词(obvious，true，natural，surprising，good，funny，possible，likely，certain等) ＋从句。
It is certain that he will come.
3．It＋be＋过去分词(said，reported，thought，expected，decided，announced 等)＋从句。
It is said that Mr Smith has arrived.
考点四 doubt 后面的从句
doubt用于肯定句时，其后的宾语从句用whether/if引导，同位语从句用whether引导；用于否定句时，宾语从句和同位语从句都用that引导。
There is no doubt that we will have an exam next week.
I doubt whether/if Tom will recover.

五、反思总结，构建知网
1. 同位语从句与定语从句的区别在于：定语从句是对先行词加以修饰、限制,而同位语从句是为了说明中心词的具体内容；that在定语从句中充当成分,为关系代词,而在同位语从句中不作任何成分,仅起连词作用.如：
The fact that we talked about is very important.我们讨论的情况非常重要.(定语从句)
The fact that he succeeded in the experiment pleased everybody.他实验成功的事实使每个人都很高兴.(同位语从句)
2.whether与if在名词性从句中的区别.
if一般只用于引导宾语从句,而whether可引导包括宾语从句在内的其他名词性从句.
1)连词whether引导的主语从句、
表
关于同志近三年现实表现材料材料类招标技术评分表图表与交易pdf视力表打印pdf用图表说话 pdf
语从句不能用if来替换.
Whether he will attend the meeting is uncertain.他是否来参加会议并不确定.
2)宾语从句中,whether常与or not搭配,可以说whether or not,而不说if or not.
I don't care whether or not she will attend the meeting.她是否来参加会议,我不介意.
3)whether可用在介词后,或不定式前,if则不可.
She doesn't know whether to get married now or wait.她不知道是现在结婚呢还是等等.
4)在某些动词后面(如discuss)只能用whether,不用if.
We discussed whether we should go on climbing.我们讨论了是否继续攀登.
