过去分词作状语

过去分词作状语同现在分词作状语一样,其逻辑主语就是句子的主语,所不同的是现在分词与主句主语存在着主谓关系,而过去分词与主句主语之间是被动关系. 过去分词或过去分词短语在句中作状语时相当于一个状语从句,可表原因,时间,条件,让步,方式或伴随. (1) 作原因状语,多放在主句之前,相当于because, since, as引导的从句. Tired from the day’s hard work, he fell asleep soon.

= (Because he was tired from the day’s hard work, he…)

由于一天的劳累工作,他很快就睡着了. Deeply moved by what he said, I promised to give him some help. (2) 作时间状语,相当于when引导的时间状语,有时在分词前直接加when, while, until等词可使其表达的时间意义更明确.如: When heated, water can be changed into steam. 水加热后可以变成水蒸气. Seen from the hill, the town looks beautiful. (3) 作条件状语,相当于if, unless引导的从句. Given another chance, he can do it better. = (If he is given another chance,...) 如果再给他一次机会,他会做的更好. United we stand, divided we fall.团结则存,分裂则亡

(4) 作让步状语. Much tired, he still kept on working. (=Though he was much tired, he...)尽管很累,他仍继续工作. (5)作方式或伴随状语. Lost in thought, he almost ran into the car in front of him. 因陷入沉思,他几乎撞到前面的汽车上. He turned away disappointed.他失望地走开了. The teacher stood there, surrounded by many students. 老师站在那儿,周围围着许多学生. 【归纳总结】

Make a thorough enquiry between students between students and teacher. 注意: (1). 过分作状语,有时前面带有连词,是状语从句的省略形式,其中省去了从句的主语和be动词,通常主语与主句的主语相同. When (it is) heated, water will boil. She won’t go to the party, unless (she is) invited. (2). 过去分词与句子的主语在逻辑上是动宾关系,改为时间,条件,原因,让步,方式状语从句时，从句的谓语动词应用被动语态(表示伴随情况多改为and +并列谓语).而现在分词与其逻辑主语则是主谓关系. (3). 过去分词作状语，从句中的主语和主句中的主语要保持一致。
