shortage of food to eat. ②（教材典句）How this could be done was a challenging question at the time. ③（教材典句）However，whether it was possible to develop a hybrid of self-pollinating plants such as rice was a matter of great debate. ④（教材典句）Today，it is estimated that about 60 percent of domestic rice consumption in China is comprised of crops generated from Yuan’s hybrid strains ... ⑤（教材典句）What impresses people most about Yuan Longping was his ongoing ability to fulfil his dreams. ⑥It is said that they will sing Beijing Opera at the Spring Festival Gala. 【会发现】 （1）以上从句都是　　　　　　　　。 （2）①⑤句中的what、 What在从句中作　　　　　　　　。 （3）②句中的How在从句中作　　　　　　。 （4）③句中的whether意为“　　　 　　”。 （5）④句和⑥句中的it、It是　　　　，真正的　　　　　　是后面that引导的从句。 【善归纳】 引导词 用法 从属 连词 that、whether 在从句中不作成分，that没有实际意义，whether意为“是否” 连接 代词 who（ever）、whom（ever）、whose、 what（ever）、which（ever）等 在从句中作主语、宾语、表语、定语等 连接 副词 when、where、why、how等 在从句中作状语，表示时间、地点、原因、方式等 （1）连词that和whether在从句中不作任何句子成分，只起连接从句的作用。 That she survived the accident is a miracle. 她在事故中幸免于难简直是个奇迹。 Whether she will come or not is still a question. 她来不来仍是个问题。 名师点津 whether引导的主语从句置于句首时，不可用if来替换。 （2）连接代词有who、 whom、 whose、 what、 which、 whoever、 whatever、 whichever等，在从句中作主语、宾语、表语或定语；连接副词有where、 when、 how、 why等，在从句中作状语。 名师点津 who 引导的主语从句表示一件“事情”，而whoever引导的主语从句指“人”。 What she did is not yet known. 她干了什么尚不清楚。 How this happened is not clear to anyone. 这事怎样发生的，谁也不清楚。 Who will be sent to America has not been decided yet so far. 到目前为止，谁将被派往美国还没有决定。 Whoever comes is welcome. 不论谁来都欢迎。 Wherever you are is my home — my only home. 你在的地方就是我的家——我唯一的家。

pity that you missed the wonderful performance. ③It is reported that a new bridge will be built here next year. ④It happened that I was out when he called me. ⑤It worried me that he didn’t come back on time. 【会发现】 以上各句中的It均为　　　 　主语，代替that引导的　　　 　从句。 【善归纳】 为了避免主语显得过长，尤其是陈述句作主语从句时，可以用it作句子的形式主语，把主语从句移到句子的末尾。it作形式主语时常用于以下句型： 句型 说明 It＋系动词＋ 形容词＋ 主语从句 常用于此句型的形容词有important、 （un）likely、 possible、 wrong、 natural、 necessary等 It＋系动词＋ 名词（短语）＋ 主语从句 常用于此句型的名词（短语）有a fact、 an idea、 an honour、 a wonder、 no wonder、 a pity等 It＋系动词＋ 过去分词＋ 主语从句 常用于此句型的过去分词有known、 believed、 proved、 said、 decided、 suggested、 thought等 It＋不及物 动词＋主语 从句 常用于此句型的不及物动词有appear、 happen、 seem、 occur、 matter等 It is very important that students （should） learn English well. 学生们学好英语很重要。 It is suggested that the meeting （should） be put off. 有人建议会议延期召开。 It depends on the weather whether they are going shopping today. 他们今天是否去购物还得看天气情况。 For example， it can be proved that China has more people than any other country in the world.

他将和谁一起去北京还不知道。 2.主语从句的时态需要根据具体语境来确定，尤其是当when引导主语从句的时候，有些同学会和when引导的时间状语从句混淆而误用现在时表将来。 When he will come back is still unclear. 他什么时候回来还不清楚。 【运用练】　单句语法填空 ①What surprised me most 　　　　　　（be） that he

the serious disease soon. 医生们真正怀疑的是我妈妈是否不久就能从这场重病中恢复过来。 （2）如果有多个主语从句用and连接，且表示一个整体概念或指同一件事时，谓语动词也用单数。当多个主语从句用and连接，且表示不同的概念或事情时，谓语动词用复数。 What he did and how he did it is a secret. 他做了什么以及他是怎么做的是一个秘密。
