3. This movie wasn't ________. He fell asleep half way A
through it. (贺州)
A. interesting enough B. enough interesting
C. interested enough
D. enough interested
本题用语法判定法。 enough修饰形容词或副词时，要放在被 修饰词的后面，故排除了 B和 D； interested“感兴趣的”，主 语为人；interesting“有趣的”，主语为物。本句的主语是this movie，故选A。

3. “too＋形容词＋ to do sth.”可以和“not＋该形容词的 反义词＋enough＋to do sth.”的结构转换。 eg：The man is too weak to do the job. ＝The man isn't strong enough to do the job. 这个人太瘦弱而不能做这项工作。
做某事”。

人/某物太……而不能做某事。
eg：The boy is too young to help you.
这个男孩太小而不能帮你。
单元语法知识梳理
【注意】有时我们需要在to do sth.的前面加上for sb.，此
时句中的动词必须为及物动词，若为不及物动
词须再加上适当的介词。 eg：The room is too small for us two to live in. 这个房间太小我们两个人住不下。 (live是不及物动词)
本题用语法判定法。 enough修饰形容词时，放在形容词后，可 知B是错误的。big enough足够大；too big太大；too small太小。 根据How big可推测出是大的，排除D；把C项代入句中理解， too...to...“ 太 …… 而不能 ……” ，意为“太大而不能容下”，不 符合逻辑。故选A。
