Seen?from?the?top?of?the?hill= When it was seen from the hill2. 作原因状语，相当于一个原因状语从句。因为淋了一场大雨，所以他全身湿透了。 _____, he was all wet. Caught in a heavy rain= Because he was caught in a heavy rain②表原因，相当于一个原因状语从句。再给他一次机会，他会做得更好。 _____，he?will?do?better. Given?another?chance3. 作条件状语 ，相当于一个条件状语从句，有时过去分词前可用if 等词。= If he is given another chance4. 作让步状语，相当于一个though/although引导的让步状语从句。尽管被许多人嘲笑，他还是继续他的研究。 _____,? he?continued?his?study. Laughed?at?by?many?people= Though he was laughed by many people5.表示伴随情况或方式: The trainer appeared, followed by six little dogs. 训练员出现了，后面跟着六条小狗。 He walked up and down the room, lost in thought. 他在屋子时走来走去，陷入了沉思。 Attention 1： 把状语从句改为过去分词作状语时有时还可保留连词，构成“连词+过去分词”结构作状语，也就是我们平时常见的状语从句的省略，即“while/when/ once/until/ if/ though等 (+ 主语+ be)+ 过去分词” 结构。● When (it is) heated, ice can be changed into water. ● Don’t speak unless (you are) spoken to.● I won’t go to her party even if (I am) invited .Tips:Attention 2：过去分词作状语与现在分词作状语的区别_____for a long time, the book looks old. 由于用了很长时间，这本书看上去很旧. _____ the book, I find it useful. 在使用的过程中，我发现这本书很有用. UsedUsing选择现在分词还是过去分词，关键看主句的主语。如分词的动作是主句的主语发出，分词就选用现在分词，反之就用过去分词。Attention 3：用分词短语作状语时, 它逻辑上的主语要与句子的主语保持一致, 否则分词短语就要有自己的逻辑主语, 这种结构称为独立主格结构。如，The job finished, we went home. ?All things considered, I think we ought to give up the job . Weather permitting, we will play the match tomorrow.?Attention 4：有些过去分词(短语)因来源于系表结构，作状语时不表动作而表状态。这样的过去分词(短语) 常见的有：(be) lost in, absorbed in, seated, dressed in, faced with , tired of 等。如Absorbed in deep thought, he didn’t hear the sound. Faced with difficulties, we must try to overcome them. 高考链接1. _____ into English, the sentence was found to have an entirely different word order. A. Translating B. Translated C. To translate D.
