名詞性從句復(fù)習(xí)備考的兩個(gè)盲點(diǎn)

1. 忽略同位語(yǔ)從句的用法

許多同學(xué)們（包括部分老師）都錯(cuò)誤地認(rèn)為，同位語(yǔ)從句不重要，一般不會(huì)考。但不一定。請(qǐng)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(dǎo)同位語(yǔ)從句，修飾名詞the story。此題的難點(diǎn)是，其中插入了believe it or not，使問(wèn)題變得復(fù)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(dǎo)同位語(yǔ)從句，修飾名詞his reason。此題的難點(diǎn)是，his reason后帶有用作定語(yǔ)的介詞短語(yǔ)for being absent from class，如果撇開這個(gè)介詞短語(yǔ)，問(wèn)題就變得簡(jiǎn)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(dǎo)同位語(yǔ)從句，修飾名詞the fact。

2. 混淆whatever與no matter what的區(qū)別

(1) 兩者的共同點(diǎn)是：均可引導(dǎo)讓步狀語(yǔ)從句，且可換用。如：

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

(2) 兩點(diǎn)的不同點(diǎn)是：引導(dǎo)名詞性從句時(shí)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(qū)別以及whichever與no matter which的區(qū)別也符合以上原則。

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

Whichever (=No matter which) day you come, I’ll be pleased to see you. 無(wú)論你哪天來(lái)，我都?xì)g迎。
