我们先来看一道题：
He was __________ tired and soon he was __________ asleep.
A. very, very B. fast, fast C. fast, very D. very, fast
此题应选 D。容易误选 A。在通常情况下，副词very 可用来修饰其他形容词或副词，以加强语气，但是有些形容词习惯上不用very而是用其他词语来修饰。如：
1. 某些以a-开头的表语形容词通常不用very修饰。如：
他睡得很熟。
正：He was fast [sound] asleep.
误：He was very asleep.
他完全是醒的。
正：He is wide awake.
误：He is very awake.
他独自一人。
正：He is all alone.
误：He is very alone.
2. 修饰worth(值得)通常不用very。如：
这本书很值得读。
正：The book is well worth reading.
误：The book is very worth reading.
2. 修饰动词习惯上不用very, 根据情况可用 very much, much, quite 等来表示类似意思。如：
我很喜欢英语。
正：I like English very much.
误：I very like English.
