名词性从句复习备考的两个盲点

名词性从句复习备考的两个盲点

1. 忽略同位语从句的用法

许多同学们（包括部分老师）都错误地认为，同位语从句不重要，一般不会考。但不一定。请看几道考题：

(1) —It’s thirty years since we last met.

—But I still remember the story, believe it or not, _______ we got lost on a rainy night. (四川卷)

A. which               B. that                    C. what                  D. when

答案为B。that在此引导同位语从句，修饰名词the story。此题的难点是，其中插入了believe it or not，使问题变得复杂了。

(2) Nobody believed his reason for being absent from class _______ he had to meet his uncle at the airport. (重庆卷)

A. why                  B. that                    C. where               D. because

答案为B。that在此引导同位语从句，修饰名词his reason。此题的难点是，his reason后带有用作定语的介词短语for being absent from class，如果撇开这个介词短语，问题就变得简单了。

(3) Doris’ success lies in the fact _______ she is co-operative and eager to learn from others. (上海卷)

A. which               B. that                    C. when                D. why

答案为B。that在此引导同位语从句，修饰名词the fact。

2. 混淆whatever与no matter what的区别

(1) 两者的共同点是：均可引导让步状语从句，且可换用。如：

Whatever (=No matter what) you say, I believe you. 无论你说什么，我都相信你。

(2) 两点的不同点是：引导名词性从句时只能用whatever，不能用no matter what。如：

她要他做什么，他就做什么。

误：He does no matter what she asks him to do.

正：He does whatever she asks him to do.

注：whoever与no matter who的区别以及whichever与no matter which的区别也符合以上原则。

Whoever (=No matter who) telephones, tell them I’m out. 不管是谁打电话，都说我出去了。

Whichever (=No matter which) day you come, I’ll be pleased to see you. 无论你哪天来，我都欢迎。
