下面对形容词(短语)作状语进行简要总结:
一、形容词(短语)作状语的语法功能
1. 表示原因,相当于一个原因状语从句。例如:
Cold and hungry, he stopped working and went home. 他又冷又饿,放下工作就回家了。
2. 表示时间,相当于一个时间状语从句。例如:
Ripe, these grapes are sweet.(=When these grapes are ripe, they are sweet.)
这些葡萄熟了的时候是很甜的。
3. 表示方式,相当于一个副词。例如:
He went home happy. (=He happily went home. ) 他高高兴兴地回家了。
4. 表示伴随状语,相当于一个并列句。例如:
Crusoe stared at the footprint, full of fear.(=Crusoe stared at it and was full of fear. )
克鲁索盯着脚印,心里充满了害怕。
5. 表示让步,相当于一个让步状语从句。例如:
Though not necessary, he came here last night. (=Though it was not necessay, he came here last night.) 尽管没有必要,昨晚他还是来了。
二、 形容词作状语的语法特征
1. 单个形容词作状语。例如:
As he looked at the goat, it rolled over, dead. 当他看着山羊的时候,山羊翻了个身,死了。
2. 形容词短语作状语。例如:
Afraid of difficulties, they prefer to take the easy road. 他们由于怕困难,宁愿走容易的路。
(这句与该题类似,用afraid表示“害怕……”是be afraid of … 但在这一句中形容词短语作状语,不能加be动词。)
3. 形容词作状语可以和从属连词连用。例如:
We can go to see him, if necessary. 有必要的话,我们可以去看他。
