encouraging.[归纳用法]1．以上例句皆为主从复合句，句中用了相当于名词作用的从句(即名词性从句)在句中充当成分。2．例句1为what引导的主语从句。例句2中it为形式主语，真正的主语为后面that引导的主语从句。3．例句3为why引导的表语从句。4．例句4为that引导的宾语从句。例句5中it为形式宾语，真正的宾语为后面that引导的宾语从句。5．例句6为that引导的同位语从句。名词性从句是在句子中起名词作用的句子。名词性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。一、名词性从句的连接词引导名词性从句的连接词有三个连词、五个连接代词、四个连接副词。连接词词形词义在从句中所作的成分连词that××if/whether是否×连接代词who(ever)(无论)谁(主格)主语、表语、宾语whom(ever)(无论)谁(宾格)表语、宾语whose(ever)(无论)谁的(所有格)定语what(ever)(无论)什么主语、宾语、表语、定语which(ever)(无论)哪个主语、宾语、定语连接副词when(ever)(无论)什么时候状语where(ever)(无论)在哪里状语how(ever)(无论)怎样，怎么状语why为什么状语二、主语从句主语从句是指在句中作主语的从句，位置与陈述句的主语相同。What

difference.我们在哪儿开会都无所谓。1．that引导主语从句，在从句中不充当任何成分，仅起连接作用，但不可省略。That you will win the medal seems unlikely.你想获得奖牌看起来是不可能的。2．whether引导的主语从句既可放在句首也可放在句尾，但if引导的主语从句只能放在句尾，前面需要用it作形式主语。Whether the sports meeting will be held is not certain now.运动会是否将举行现在还不能确定。Whether the work can be completed on time is doubtful.＝It is doubtful whether/if the work can be completed on time.这项工作能否按时完成还不确定。3．若主语部分结构较长，可以使用形式主语it，把真正的主语从句放于后面。It is announced that our school is going to start an activity of “Crazy English” before daily morning exercises.学校通知每日早操前将开展“疯狂英语”活动。It is necessary that people should learn to face the reality.人们应该学会面对现实是有必要的。[即学即练1]　单句语法填空①It is certain that she will do well in her exam.②How we understand things has a lot to do with what we feel.③It is

Monday.她说她将会来这儿并让我等到星期一。2．if和whether引导宾语从句的区别：①在动词不定式之前只能用 whether。②在whether...or not 的固定搭配中，只用 whether。③在介词后，只能用whether。④作 discuss 的宾语时，只能用 whether。⑤宾语从句放在句首表示强调时，只能用 whether。3．带复合宾语(宾语＋宾语补足语)的句子，that引导的宾语从句经常移到句子后面，而用it作形式宾语。4．表示喜欢、憎恶等心理活动的动词(短语)后习惯上先加个形式宾语it，再接宾语从句。例如：hate，dislike，love，don't mind，feel like，appreciate，rely on，count on，see to等。We think it possible that you can finish the work today.我们认为你今天能够完成这项工作。5．宾语从句的否定转移：think，believe，suppose，imagine等动词后的宾语从句中的否定词要转移到主句中，即主句的谓语动词用否定式，而从句的谓语动词用肯定式。I don't think we need to waste much time on it.我想我们不必在这上面浪费太多时间。(形式上否定)[即学即练2]　单句语法填空①I hate it when they talk with their mouths full of food.②Once we were left to decide whether to have a picnic in a park or go to a museum.③I want to be liked

time.问题在于我们是否能及时完成这项工作。1．that在引导表语从句时无词义，在从句中不充当任何成分，仅起连接作用，但不可以省略。The fact remains that we are still not advanced enough.事实依然是我们还是不够先进。2．whether可引导表语从句，但if却通常不用于引导表语从句。His first question was whether Tom had arrived yet.他的首要问题是汤姆是否已经到达。3．引导表语从句的引导词还可用because，as if，as though，as。The sky is overcast with dark clouds.It seems as if it is going to rain soon.天空乌云密布。似乎很快就要下雨了。[即学即练3]　单句语法填空①The problem is who/whom we can get to replace her.②I'm afraid he's more of a talker than a doer，which is why he never finishes anything.③The system works well in the lab，but the question is whether it will work in reality.五、同位语从句在复合句中用作同位语的从句叫同位语从句。它一般跟在某个名词后面，用来说明前面名词的具体内容。常见的这类名词有：fact，news，hope，truth，idea，suggestion，thought，question，promise，order，problem，belief，word，message，information，proof，announcement，desire，doubt，proposal，advice，possibility等。The
