　　2012届高三英语一轮复习精品学案：语法部分第7讲名词性
　　（要点透析）
　　一个句子在另一个句子中充当主语、宾语、表语、同位语，相当于名词，故称为名词性从句。名词性从句分为主语从句、宾语从句、表语从句和同位语从句四大类。
　　它们有如下共同特点：
　　1．连接词基本相同，它们是：从属连词that, whether, as if；连接代词what, who, which, whose, whatever, whoever, whomever, whichever; 连接副词where, when, why, how, wherever, whenever。
　　2. 从属连词that本身无意义，在名词性从句中不作句子成分，只起连接作用。
　　3. 名词性从句中，除了关联词要提到句首之外，一律要用陈述句语序。
　　一、主语从句
　　1．由that(不充当句子成分，仅起引导作用)引导的主语从句，通常用it作形式主语。(常见句型参见M7U1疑难句型)
　　2．几种常用的含主语从句句型：
　　It's said that…据说
　　It's written that…据记载
　　It's reported that…据报道
　　It's well known that…众所周知
　　It's (so) happened that…碰巧
　　It's certain that…确信
　　【注意】当人作主语时，表语用sure或certain, 但在句型It is certain that…中，不可用sure替代certain。
　　【疑难点击】
　　1．由what, whatever, whoever等引导的主语从句，必须置于谓语动词之前，不能用it作形式主语。
　　Whatever was said here must be kept secret.
　　Whoever breaks the law will be punished.
　　2. 由which, when, where, whether等引导的主语从句，可置于谓语动词前，也可用it作形式主语。但如果是疑问句，就只能用it作形式主语。
　　Whether he'll come or not makes no difference.＝It does't make any difference whether he'll come or not.
　　Hasn't it been decided yet when and where we'll hold the sports meet?
　　二、宾语从句
　　it作形式宾语的常见句型
　　①主语＋ think/consider/find/feel/make＋it＋adj./n. ＋ that－从句
　　I really find it a pity that you didn't come to the party.
　　②主语＋hate/dislike/love/like ＋it ＋ when－从句表示对某一情况的喜好或厌恶
　　I hate it when people speak with their mouths full.
　　③主语＋appreciate ＋ it＋ if－从句
