第4讲 名词性从句-【暑假辅导班】2021年新高二英语暑假精品课程（北师大2019版）

名词性从句的复习要点 　　 一．名词性从句包括主语从句、表语从句、宾语从句和同位语从句。 　　※ 区分同位语从句和定语从句。 　　The news ____a theme park will be set up here is true. A. that B. which C of which D. / 答案：A 定语从句是修饰、说明名词或代词 ( 先行词 ) 的，而同位语从句则是揭示该名词具体内容的。所以，从某种程度上说，名词和同位语从句之间可以划等号。但要切记 which 不能引导同位语从句。 　　※that 与what 引导主语从句时的区别： 　　1.It worried her a bit ______ her hair was turning grey . 　　A . while B . if C . that D . for 　　2. ______ is a fact that English is being accepted as an international language . 　　A . There B . This C . That D . It 　　答案：C. D 二. that 在名词性从句中不充当任何成份，也无词义，仅起连接作用。引导并列的宾语从句时，第二个 that 以及引导主语从句、同位语从句时，不可省略。that 从句作主语时，常用句型结构为：It is ( was ) + adj . 或n . + that 从句: It is impossible that he has enrolled at the university. It is a fact that he was forced to attend the evening class. 在 The reason for . . . ( Why . . . ) is that . . . 结构中的 that 不可用 because 替代。 The reason for his illness is that he was caught in the rain last night. The reason why he was ill is that he was caught in the rain last night. 　1.　______ you have done might do harm to other people . 　　 A . That B . What C . Which D . This 　2.　______ he said at the meeting astonished everybody present . A . What B . That C . The fact D . The matter　　 3. ______ we can't get seems better than ______ we have . A . What ; what B . What ; that C . That ; that D . That ; what　　 答案：1.B 2.A 3.A 三．what 本身在名词性从句中充当一定的成份，或主语、或宾语、或表语。这时 what 具有两种含义：保留疑问的意义，即“什么，什么样的”；相当于“先行词 + 定语从句”结构的用法，“the thing／fact／matter that . . . ”常译为“所……的 ( 东西或事情 ) ”。区分用 that 还是 what 的依据是看从句中有没有主语、表语或从句的及物动词带不带宾语，若带有宾语，则用 that ; 若无宾语，则用 what。 　 四．whether 和 if 两个连词的不同用法。 　　1.______ the 2000 Olympic Games will be held in Beijing is not known yet . 　　A . Whenever B . if C . Whether D . That 　　2.______ we'll go camping tomorrow depends on the weather . 　　A . If B .Whether C . That D . Where 答案：1.C 2.B 　　　whether 和 if 意为“是否”，虽不充当句子成份，但也不可省略。两词在动词后引导宾语从句时，常可互换。但在下列情
