注意：在名词性从句中，除了 关联词在从句之首外，其它 部分应用陈述句 的语序。
一、主语从句
主语从句在复合句中作主句的主语。引 导主语从句的词that,whether,if， who,which,what,when,where,ho w,why,whoever,whichever,whatev er等 。
• 2）It+be+形容词 (obvious,true,natural,good,wonderful,funny,p ossible,likely,certain,Probable,important,stran ge 等）+ that从句
• It is necessary that a college student (should) master one or two foreign languages.

• It happened that I had driven that kind of car before. • It turns out that our team has won the game. • It occurred to me that we should get in touch with
• 3）It + be + 动词的过去分词 (said,reported,thought,expected,decided,announcedquested, proposed, desired等) + that从句
• It is reported that he is a scholar from New Zealand.
1. 连接词that在句中无词义，只起连接作用。 (that位于句首时不能省略），有时为避免句 子头重脚轻，常用it代替主语从句作形式主 语放于句首，而把主语从句置于句末。主语 从句后的谓语动词一般用单数形式。
That he will come and help us is certain. （不常用结构）
• 2.if/whether引导的主语从句
• Whether the work can be completed on time is doubtful.
• =It is doubtful whether/if the work can be completed on time.
• 注意：1)whether引导的主语从句可置于句首也 可置于句中，但由if引导的主语从句不能置于句首， 只能放于主句后。
It is certain that he will come and help us. （常用结构）
• 常用句型如下：
• 1）It+be+名词词组（no wonder,an honour,a good thing,a pity,no surprise,a shame等） +that从句
• It’s a pity that you didn’t come to the party.
decided. • How much we can spend must be agreed on.
Exercises: 1.I hate _A__ when people talk with their mouths full. A. it B. that C. these D. them 2. I feel __B__ strange that he should be so careless. A. / B. it C. that D. how
3. It worried her a bit __B__ her hair was turning grey. A．while B. that C. if D. for
注意：主语从句的主谓一致
1.主语从句通常被看作一个整体,主句的谓语动词用单数 形式.
That they will come is certain. 2.由who, whoever引导的主语从句的单复数要视从句中 的单复数而定. Whoever say that are to be punished. Who are going there have been decided.
高考强化阶段语法
名词性从句：在复合句中起名词作 用的从句叫做名词性从句。
名词性从句的种类：
• 1.When we will start is not clear. 主语从句 • 2.Mrs Black won’t believe that her son has become a thief. 宾语从句 • 3. My idea is that we should do it right now. 表语从句 • 4.I had no idea that you were her friend. 同位语从句
• 2)连接代词和连接副词在句中既保留自己的 疑问含义、又起连接作用，在从句中充当从句的 成分。
• 3.wh-疑问词及whoever,whatever,whichever引 导的主语从句：
• whoever相当于anyone who，表泛指关系。 Whatever相当于anything that。
