Whoever told you that ______ (be) lying. b: 两个/多个连接词引导一个主语从句，主句谓语用单数。 When and where the students are going _____ (be) not decided yet. c: and连接两个主语从句时，主句谓语用复数。 When he left and where he went _____ (be) not important. was was is are 五：主语从句后谓语动词的数 d: What引导主语从句时，如果主句的表语是复数名词，主句谓语也可用 复数，也可单数（通常用复数的多）。   What they need ______ (be) books. e: 如果主语从句本身明显表示复数意义，比如主语从句的动词和补语都 是复数，那么主句的动词也可用复数。 What _____ (be) often regarded as poisonous fungi _____ (be) in fact edible. are/is are are fungus [sing.] 主语从句太长怎么办？ That all countries work together is important. 用一个 It 来解决问题！ It is important that all countries work together. 一般来说主语从句都是放在句首,但有时为了使句子 结构平衡, ★主语从句为了避免头重脚轻现象,用it做_______，而把从句放在后面充当_________。 真正的主语 形式主语 17 It作形式主语 1. That the earth moves around the sun is well known. = It is well known that the earth moves around the sun. 2. That she has made such a mistake is a pity . = It is a pity that she has made such a mistake. 3. Whether he'll come here isn't clear.   = It isn't clear whether/if he'll come here. 注意：主语从句位于句首时, 不能用if 引导, 主语从句后置时, 才可以用if引导。 用一个 It 来解决问题！ 18 (1) It +be+形容词（obvious, true, surprising, wonderful, possible, likely, certain) +that 从句 (2) It + be +过去分词(said, reported, thought, expected, decided, announced, suggested 等)+that从句 (3) It + be +名词词组(a pity, a shame, good news, an honor, no wonder等)+that从句 (4) It+不及物动词/动词短语(seem, appear, happen, matter, turn out, occur to等)+that 从句 (5) It is necessary/important等 + that(should) do It is suggested/ordered等 + that (should) do 接虚拟语气 六： it作形式主语(的主语从句） 名词性从句的分析思路:“两步走” Step1 ：判断从句类型。如果该从句在整个句子中担任主语，则为主语从句；如果从句担任宾语，则为宾语从句；如果从句担任表语，则为表语；如果从句担任同位语，则为同位语从句。 Step2：确定从句的连接词。如果从句完整，且无“是否”涵义，则用that引导从句；如果从句完整，且有“是否”涵义，则用whether或if引导从句；如果从句不完整，则需分析从句缺什么成分，从而确定连接词（what, who, whose, which, how, why, when, where等）。 七：区别 1.that 与 what what既有引导主语从句的作用，同时又在从句中作句子成分（主语、 宾语、表语等），这时 what 相当于 all that/everything that...，意为 “所……的（东西、事情、话等)”； that 只起连接作用，本身无实际意义，在从句中也不充当任何句子成 分。但that引导的主语从句放在句首时，不能省略that。 What is done can't be undone. （谚语）已成定局，无可挽回。 What we can't get seems better than what we have. 我们得不到的东西似乎比已得到的更好。 That we should work out a plan to deal with the present serious situation is important. 2.who和 whoever, which 和whichever, what和whatever 引导主语从句时，who表示“谁”，whoever表示“无论谁”；which表示“哪一个” whichever表示“无论哪一个”；what表示“什么，……的（东西/事情）”，whatever表 示“无论什么”。who，which含有疑问，what表示“什么”时也含有疑问，whoever，whichever, whatever 不含有疑问。 Who can work out the maths problem is unclear. 谁能解出这道数学题还不清楚。 Whoever can work out the maths problem will be rewarded. 无论谁能解出这道数学题都会被奖励。 Whichever way you choose has nothing to do with me. 你选择哪条路都和我没有关系。 Which book he is looking for is not known to us. 我们不知道他在找哪一本书。 主语从句的规律： 找出下列句子中的错误，并总结规律 例1.When will he come is not known. 规律一、主语从句一律用_________， 即_______在前，_______在后。 正：When he will come is not known. 陈述语序 主语 谓语 主语从句的规律： 例2.
