第二讲　名词性从句 考点一　主语从句 It作形式主语,常见的句型有: (1)It+be+形容词(obvious、true、natural、surprising、important、good、wonderful、funny、possible、likely、certain、probable、etc.)+that从句 It is obvious that different people have different thoughts. 不言而喻,不同的人有不同的想法。 (2)It+be+名词词组(no wonder、an honour、a good thing、a pity、no surprise、etc.)+that从句 It is no wonder that the children love to visit the farm. 孩子们喜欢去农场玩是不足为怪的。 (3)It+be+过去分词(said、reported、thought、expected、decided、announced、arranged、etc.)+that从句 It is reported that a space station will be built on the moon next year. 据报道,明年会在月球上建一个空间站。 (4)It+不及物动词(seem、appear、happen、matter、etc.)+that从句 It appears that the two leaders are holding secret talks. 看来两位领导人正在进行密谈。 [特别提示] that引导主语从句时,在从句中不作任何成分,也没有词汇意义,但一般不可以省略。 whether/if表示“是否”,若主语从句位于主句的谓语动词前,只能用whether。若用it作形式主语,则whether与if可互换。 wh-类连接词包括连接代词(who、whom、whose、what、whoever、whomever、whatever等)和连接副词(when、where、why、whenever、wherever等)。连接代词在从句中作主语、宾语、表语或定语,连接副词在从句中作状语。其语序为wh-类连接词加陈述句。 That the earth goes around the sun is known to us all. 众所周知,地球围绕着太阳转。 It’s uncertain whether/if he’ll come this evening. 他今天晚上是否会来还不确定。 [对点演练] 1.语法填空高频考点 ①　　　　 is so breathtaking about the experience is the out-of-this-world scenes.(2021·新高考全国Ⅰ,语法填空,56)  ②Therefore,it is advisable　　　　 you should value and treat them with care.  ③　　　　 impressed the tourists most was the peaceful atmosphere and the friendly people there.  答案及剖析: ①What　考查主语从句。句意:这次经历最令人激动的是超凡脱俗的景色。此处是主语从句,从句缺乏主语,应用what引导,指代“经历的事情”。故填What。 ②that　考查主语从句。本句为it作形式主语的主语从句,该从句不缺任何成分。故填that。 ③What　考查主语从句。设空处引导主语从句,在从句中作主语,且表示“所……的事/物”。故填What。 2.短文改错高频考点 ①I think that impresses me about his painting is the colours he uses. ②We all thought it was a pity which the concert was put off. ③Which makes me feel worse is that they don’t give me the chance to explain. 答案及剖析: ①将that改为what　考查主语从句。I think后的从句中缺少主语,用what作主语,同时引导主语从句。故将that改为what。 ②将which改为that　考查主语从句。此处it为形式主语,真正的主语为that引导的从句。故将which改为that。 ③将Which改为What　考查主语从句。本句为主语从句,从句中缺少主语,表示“所……的事/物,应用what。故将Which改为What。 考点二
