[解题技法指导]
技法一:句子成分分析法
看从句是否缺少成分,不缺少成分就用that, whether/if;缺少成分就用wh 类连接代词。
(1)抓住同位语从句的特征:同位语从句通常跟hope, fact, truth, belief, news, idea等抽象名词之后。

A.That B.What
C.Who D.Which
[分析] 考查主语从句。句意:让这本书如此非凡的是作者创造性的想象力。所填词引导主语从句,并在从句中作主语,故选B。

近几年来,在考查名词性从句题目时,命题 ( http: / / www.21cnjy.com )人有意把句子结构复杂化,如加入插入语、倒装句、强调结构、复杂从句、易混结构等。做题时,若能正确分析句子结构,把握句子脉络,就能正确理解句子含义,提高答题的速度和准确率。
