f) 作程度状语，如：
The wind rose and it became freezing cold. g)作目的状语，如：
Yesterday she went shopping with his classmates. h) 作让步状语（相当于让步状语从句），如：
Though warned of the danger, the children went on skating on the thin ice.(=Though they were warned of the danger, ．．．)
要点提示：分词作状语，其逻辑主语就是句子的主语，如果分词表示的是主动、进行的动作，则用现在分词作状语；如果分词表示的是被动、完成的动作或状态，则用过去分词作状语，如：
Following the old man, he stepped into the room. Followed by the old man, he stepped into the room. Greatly interested ,I asked how he played these new works. ⑹ 不定式、现在分词作独立成分时的比较
A．不定式作独立成分，表示不定式独立于句子的其他成分，是英语表达的一种方式，不常用，如：
To tell you the truth, I am almost freezing. To be honest, I don’t like being left alone at home.
B．现在分词作独立成分，用来表示说话人的态度或看问题的角度，如： Generally speaking, boys are physically stronger than girls. Judging from his accent ,he must be an American.
注意：
重点：Need, want, require（要求，需要）, deserve(应得，值得), be worth值得），not bear(经不住) 后面接doing主动表被动。 The book is worth reading. 这本书值得一读。
The old building requires repairing. 这座古建筑需要修了。
These young seedlings will require/need looking after (=need to be looked after) carefully. 这些幼苗将需要小心的照管。
Your hair wants/needs cutting (needs to be cut). 你的头发该剪了。
