　　动词的过去分词作状语

　　Grammar (动词的过去分词作状语)

　　过去分词作状语可以表示时间、原因、条件、让步、方式或伴随情况等。表示时间、原因、条件、让步的过去分词相当于相对应的状语从句。其逻辑主语一般应与句子的主语一致，过去分词与逻辑主语一般是被动关系。

　　1.作时间状语.

　　When heated, water can be changed into steam.水加热后可以变成蒸汽.

　　注意:作时间状语时,过去分词如果同时表被动和动作完成,常可换用现在分词的被动完成式;过去分词如果只表被动,不表完成,则不可与现在分词的被动完成式换用.如:

　　Discussed(Having been discussed) many times, the problems were settled at last.

　　在讨论了多次之后,问题终于解决了. (过去分词既表被动又表完成)

　　Seen from the hill, the park looks very beautiful.

　　从山上看这个公园非常漂亮. (过去分词只表被动) 　 　

　　相当于when引导的状语从句.如果两个动作同时发生,可在分词前用when, while等使其时间意义更明确

　　2.作原因状语:

　　Given advice by the famous detective, the young lady was no longer afraid. (Since/ As she was given by the famous detective...)

　　有了著名的侦探的指点,姑娘不再害怕了.

　　Frightened by the noise in the night, the girl didn't dare to sleep in her room. (Because she was frightened by the noise...)

　　姑娘被夜里的响声吓坏了,不敢在自己的屋里睡觉了.

　　Done in a hurry, his homework was full of mistakes.

　　他匆忙做的作业错误百出.

　　相当于as, since, because引导的从句,这类状语多放在句子前半部分

　　3.作条件和假设状语.

Given more attention(If they had been given more attention), the cabbages could have grown
