4、don t like what he does every day. ( 宾语从句 ) I don t know about the man, Mr. White. ( 同位语 ) I don t know about the fact that he is a teacher.

43、glasses. 名词性从句易混知识归纳名词性从句易混点归纳名词性从句在英语学习过程中占据极其重要的位置，同学们经常为一些易混点所困扰，现总结名词性从句的易混点如下：我主要从whether 与 if、 that 在名词性从句中是否省略、同位语从句与定语从句的区别、reason后面的名词性从句、what 引导的一种独特的名词性从句、check、 make sure 后面的宾语从句、what、whatever、who、whoever 等引导的名词性从句几个方面进行说明、讲解，当然还有其他方面的易混点知识，这里就不进行一一叙述了。易混点一whether 与 if 二者都可以作“是否”讲，能引导名词性

44、从句，都不能省略。1.在及物动词后引导宾语从句时可以互换；注意：在某些动词后（如:discuss）只能接 whether，不能跟 if 。如：We discussed whether we should close the shop. 2.引导主语从句、表语从句、同位语从句时都用whether，不用 if。如：精选学习资料 - - - - - - - - - 名师归纳总结 - - - - - - -第 7 页，共 29 页8 The question whether he should come himself or send another man hasn t been decided.

45、Whether he will win is all the same to me. The question is whether you can go there yourself. 如果用形式主语，if 和 whether 都可以It is unknown whetherif she is ill. 3.如果 whether 后紧跟 or not，不用换做if ；若 whether 与 or not 分开使用，则可以换作if 。如：I wonder whether or not he has arrived at the destination. I don t know whether

46、if I can come or not. 4.若宾语从句为否定结构，则多用if，而不用whether。如：I don t care if he doesn t show up.（在乎，炫耀）5.在介词后引导宾语从句或与带to 的动词不定式结合而构成不定式的复合结构时，只能用whether，而不用if 。如：I haven t settled the question of whether I will go back home. She doesn t know whether to get married now or wait. 易混点二that 在名词性从句是否省略that 用来引导宾

47、语从句、表语从句、主语从句、同位语从句这四类名词性从句。在句子中that 有时可以省略，有时不省略，有时两者皆可。1.宾语从句中的that 在口语中常省略，但在下列情况中，that 应当保留。（1）当主、从句之间有时间等状语时，that 不能省略，否则会产生歧义。He said last night that he did some reading. He said last night he did some reading. 其含义有两个：他昨晚说他看了点儿书。或他说他昨晚看了点儿书。（2）主、从句之间有插入语时同样不可省去that。如：I don t doubt，in any case，

48、 that we will win the match. （无论如何，我都不怀疑我们会赢那场比赛） 。（3）引导两个或两个以上的宾语从句时，第二个或第二个以上的宾语从句中的that 则不易省略。如：She said Lesson 82 was very important and that she should learn it well. （若省略，后一从句则可能与上句she said并列）Everybody could see what was happening and that poor Rose was really frightened. （并列宾语从句。省去that，则变为并列句

49、。 ）（3）如果宾语从句中含有主从复合句，that 一般不宜省略。如：They promised me that if I worked hard from then on，they would buy me a computer. （4）宾语从句提前时，that 一般不省略。如：That Bob was really frightened ，I can t believe. （5）简短回答中的宾语从句，that 不宜省略。如：What do you assume from his attitude ？（你从他的态度中猜测到什么了？）That he was frightened. （6）当 i

50、t 作形式宾语代替that 引导的宾语从句时，一般保留that。如：I found it quite a surprise that everybody in that city has a car. 2.引导主语从句的that一般不可省略，但若用it 作形式主语，that 则可省略。That the earth moves around the sun is known to all. 精选学习资料 - - - - - - - - - 名师归纳总结 - - - - - - -第 8 页，共 29 页9 It is known to all （that）the earth moves arou
