第12讲：名词性从句（思维导图+知识详解+专题过关） 2023年初升高英语暑假衔接精品课程（原卷版） 思维导图 知识详解 在句子中起名词作用的句子叫名词从句(Noun Clauses）。名词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。 1.That she will help me made us happy.（主语从句）  2.I can understand what he said.（宾语从句）  3.This is where I was born.（表语从句）  4.The fact that a heavy earthquake happened made me crazy.（同位語从句）  引导名词性从句的连接词可分为三类： （1）从属连接：that, whether, if（不充当从句的任何成分） （2）连接代词：what, whatever, who, whoever, whom, whose, which.（充当从句中的主语、宾语、表语或定语） （3）连接副词：when, where, how, why（在从句中作状语） 名词性从句语序： 陈述语序：主语+谓语+（其他） 一．主语从句 （Subject Clause） 一．定义 主语从句即在主从复合句中充当主语成分的句子。 That we all should attend the meeting is important. It is important (that) we all should attend the meeting. 二．主语从句的连词 1、连词that（句首不可省略），whether，if引导的主语从句。 That the earth is round is true.=It is true that the earth is round. That you missed such an interesting film is a pity.=It is a pity that you missed such an interesting film. That she is still alive is sheer luck（纯粹的运气）.=It is sheer luck that she is still alive. It remains unknown whether/if we will go for an outing tomorrow. 注意：if / whether 在主语从句中的用法 whether/if含有“是否”的意思，if不与or not 直接连用，whether可与or not直接连用。即if/whether...or not/ whether or not.其语义不变。但如果主语从句位于句首则必须用连接词whether，不用if。 If the meeting will be put off hasn't been decided yet. （X） Whether the meeting will be put off hasn't been decided yet. (√) It is still a question whether/if it is true or not.(√) Whether it is true or not is still a question.(√) It makes no difference whether or not he comes.(√) 2、连接代词who，whom,whose，what，which，wh+ever引导的主语从句。 Who will come to teach the students is not known. Whom the watch belongs to is unknown. Whose watch was lost is unknown. Whatever he said wasn't true. 3、连接副词 where，when，how，why引导的主语从句。 Where the library is to be built has not been decided yet. When we start the work is an important question. How this happened is not clear. Why she was late for school is quite clear now. 注意：主语从句中的连词不能重叠使用。 That whether we'll
