非谓语动词
2-4：分词做副词
此类分词多为现在分词，有副词very的意味，修饰之后的形容词。
例：it's freezing/biting/perishing cold today.
（今天天气非常冷。）
it's boiling hot today.
（今天天气非常热。）
he was exceeding/exceedingly glad to hear it.
（他非常高兴听到它。）
we're having a ripping good time.
（我们玩得很愉快。）
但也有过去分词做副词用的例子。
例：an estimated 54 people were killed in the air crash.
= it is estimated that 54 people were killed in the air crash.
（据估计有54人在飞机失事中遇难。）
比较：a great many students are more and more interested in learning english.
（许多学生对学英文愈来愈感兴趣。）
注意
少数形容词也有副词的功能，修饰之后的形容词。
例：he is dead wrong.
（他大错特错。）
it's awful hot today.
（今天热得要命。）
the answer is doubtless/doubtlessly/without doubt/undoubtedly correct.
（此答案毫无疑问是正确的。）
