whether 引导，而不用 if。2.形式主语 it 作形式主语的常见句型：(1)Itbe形容词(necessary/likely/important/uncertain 等)that 从句(2)Itbe名词(短语)(a pity/a shame/no wonder 等)that 从句(3)Itbe过去分词(said/believed/reported 等)that 从句(4)It不及物动词(seem,appear,happen,matter 等)that 从句 It is necessary that you(should)apologise to him.你向他道歉是有必要的。Its no surprise that our team has won the game.我们队获胜一点儿都不令人吃惊。It is decided that the meeting will be put off till next Friday.根据决定，会议被推迟到下周五。It doesnt matter whether you pay by cash or credit card in this store.2 在这个商店里你用现金支付还是信用卡支付都没有关系。当 it 作形式主语，主语从句放在句末时，用 if 或 whether 引导均可，但如果被后置的主语从句中引导词后接 or not 时，只能用 whether。考点 2 宾语从句 1.宾语从句的引导词 引导词 作用 连接词 that,whether,if 只起连接作用，不在从句中作成分 连接 代词 what,who,whom,which,whichever,whatever,whoever 在从句中作主语、宾语、表语或定语 连接 副词 when,where,how,why 在从句中作状语 Our teachers always tell us to believe in what we do and who we are if we want to succeed.老师总是告诉我们，如果我们想要成功，要相信我们所做的事情和我们自己。(1)that 引导宾语从句时，常被省去，但下列情况下不能省略：动词后跟有多个 that引导的宾语从句时，只有第一个 that 可省略，其余的不可省略；宾语从句前有插入语时；that 引导的从句位于句首时。(2)一般情况下介词后只能用 wh类连接词引导宾语从句。介词后的宾语从句，连接词表示“是否”时，只能用 whether，不能用 if。2.形式宾语 宾语一般放在及物动词或介词之后，但是，在下列情况下，须用 it 作形式宾语，而将真正的宾语(常为不定式或从句)后置。(1)动词 find/feel/think/consider/makeit宾补(形容词或名词)不定式/从句(2)动词 hate/like/dislike/appreciate/enjoyit从句(3)短语动词 see to/depend on/rely onit从句(4)固定搭配 take it for granted that/owe it to sb.that从句 No matter where he is,he makes it a rule to go for a walk before breakfast.无论他在哪里，他都习惯在早餐前散步。I shall see to it that he is taken good care of when you are absent.当你不在的时候，我负责把他照顾好。3 3.宾语从句的时态 一般情况下，宾语从句须与主句的时态保持一致，即主句是一般现在时，从句可根据具体情况选用合适的时态；主句为过去的某种时态，从句须用相应的过去的某种时态。当从句的内容为真理或客观事实时，须用一般现在时。考点 3 表语从句 1.表语从句的引导词 引导词 作用 连接词 that,whether 只起连接作用，不在从句中作成分 连接代词 what,who,whom,which,whichever,whatever,whoever 在从句中作主语、宾语、表语或定语 连接副词 when,where,how,why 在从句中作状语 The most important result for the user is that the product does what is intended.对用户来说，最重要的是产品达到了预期的效果。This is where we usually think its easier to just give up.这就是我们通常认为更容易放弃的地方。if 不能引导表语从句；that 引导表语从句时不能省略。2.as if/as though 引导表语从句 as if/as though 意为“好像，仿佛”，引导的表语从句常跟在系动词(如 seem,appear,look,taste,sound,feel,smell 等)之后。若表语从句所述的是非真实的情况，从句用虚拟语气；若所述的是事实或是极可能发生的情况，从句用陈述语气。The thick smog covered the whole city.It was as if a great black blanket had been thrown over it.浓雾笼罩着整个城市，这就好像一块巨大的黑色毯子被扔到了它的上面。3.其他常考的表语从句(1)This/That/It is why表语从句(表示结果)“这/那就是的原因”(2)This/That/It is because表语从句(表示原因)“这/那是因为”(3)The reason why.is that表语从句“的原因是”考点 4 同位语从句 同位语从句在句中作某一名词的同位语，位于该名词之后，用以说明该名词的具体内容。同位语从句所修饰的名词：advice,conclusion,doubt,fact,hope,idea,news,promise,question,suggestion,thought,truth,wish,word 等。同位语从句的引导词：that,4 whether,how,where,when,why 等。The fact that you are wrong cant be changed by you or me.你错了这个事实，是你我不能改变的。that 引导同位语从句和定语从句的区别：that 引导定语从句时，that 既起引导词的作用，又在从句中充当句子成分；如果在从句中作宾语，that 还可以省略，所修饰的名词指物时可用 which 替换。引导同位语从句时，that 在从句中不充当任何句子成分，不能省略。The news that they had won the game soon spread over the whole school.他们比赛获胜的消息很快传遍了学校。(同位语从句)The news that you told me yesterday was really disappointing.你昨天告诉我的消息实在令人失望。(定语从句)考点 5 名词性从句重点辨析 1.that 和 what 的区别 that 引导名词性从句时，在主从句中不充当任何句子成分，也没有任何含义；而 what引导名词性从句时，在主从句中都要充当一定的句子成分，what 可以分解成定语从句中的“先行词关系代词”，即常说的“先行词that/which/who”。Its a shame that he has made such a mistake.真遗憾，他犯了这样一个错误。I will do what I can(do)to help him.我将尽我所能帮助他。2.同位语从句与定语从句的区别 判断是定语从句还是同位语从句可以用“加词”的方法，即在名词和从句之间加入一个be 动词，如果句子意思成立，则是同位语从句，否则，则是定语从句。试比较：The notice that the meeting had to be put off was true.(同位语从句)The notice was that the meeting had to be put off.The notice that he read just now was true.(定语从句)3.whether 与 if 引导的名词性从句(1)whether 引导的主语从句既可放在句首也可放在句末，但 if 引导的主语从句只能放在句末，且前面需用 it 作形式主语。Whether it is true remains a question.这是否是真的依然是个问题。It is unknown if he will attend the meeting.他是否会来参加会议还不清楚。(2)whether 与 if 引导宾语从句时，大多数情况下可以互换，后面直接跟 or not 时用 5 whether，用于介词后引导宾语从句时也用 whether。We dont know whether or not she was ready.我们不知道她是否准备好了。Im interested in whether youve finished the work.我对你是否完成了这项工作感兴趣。(3)whether 可引导表语从句和同位语从句，而 if 不可以引导这两种从句。The question is whether it is worth doing.问题是它是否值得去做。The question whether the work was worth doing has not been decided.这项工作是否值得去做的问题还没有确定。【技巧点拨】名词性从句解题三步走 第一步：根据两句之间的意义和逻辑关系，或者根据句式结构判断是否是名词性从句。第二步：一旦判断是名词性从句，就根据名词性从句中缺少什么句子成分来确定选用什么连接词。若从句中缺少主语、宾语或表语，用连接代词。指物用 what,whatever；指人用 who,whoever。第三步：如果不缺少主语或宾语，要看从句是否有疑问。如果没有疑问用 that，有疑问则根据句意使用 when,where,why,how,whether 等。.单句语法填空 1.(2021新高考卷)Going to Mount Huangshan reminds me of the popular Beatles song The Long and Winding Road.What is so breathtaking about the experience is the
