名詞性從句復習備考的兩個盲點

1. 忽略同位語從句的用法

許多同學們（包括部分老師）都錯誤地認為，同位語從句不重要，一般不會考。但不一定。請看幾道考題：

(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

答案為B。that在此引導同位語從句，修飾名詞the story。此題的難點是，其中插入了believe it or not，使問題變得復雜了。

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

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

答案為B。that在此引導同位語從句，修飾名詞his reason。此題的難點是，his reason后帶有用作定語的介詞短語for being absent from class，如果撇開這個介詞短語，問題就變得簡單了。

(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

答案為B。that在此引導同位語從句，修飾名詞the fact。

2. 混淆whatever與no matter what的區別

(1) 兩者的共同點是：均可引導讓步狀語從句，且可換用。如：

Whatever (=No matter what) you say, I believe you. 無論你說什么，我都相信你。

(2) 兩點的不同點是：引導名詞性從句時只能用whatever，不能用no matter what。如：

她要他做什么，他就做什么。

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

正：He does whatever she asks him to do.

注：whoever與no matter who的區別以及whichever與no matter which的區別也符合以上原則。

Whoever (=No matter who) telephones, tell them I’m out. 不管是誰打電話，都說我出去了。

Whichever (=No matter which) day you come, I’ll be pleased to see you. 無論你哪天來，我都歡迎。
