初一英语知识点总结：学习动词-ed形式作定语
过去分词作定语往往与被修饰的词靠得很紧,渐渐地成为一个复合词。这种分词叫分词形容词(the Participle Adjective),实际上相当于一个单纯的形容词,除表示“完成”的动作之外,还表示“被动”的意义。如：
spoken English (英语口语);iced beer (冰冻啤酒);cooked food (熟食); fried chips (炸土豆条);
但要注意不及物动词的过去分词常表示“完成”的动作,而不表示“被动”意义。如: boiled water(开水); fallen leaves(落叶) ; the risen sun(升起的太阳)等。
(1)前置定语 单个的动词-ed形式,一般放在被修饰的名词的前面,作前置定语。
The excited people rushed into building. 激动的人们冲进大楼。(=the people who were excited)
Lost time can never be found again.虚度的时光,无法挽回。(=time which is lost)
(2)后置定语 ①少数单个动词的-ed形式,如left等,只能作后置定语。
1. Everything used should be marked.所有用过的东西应该做好标记。
2. Among the invited were some ladies.被邀请的人中,有些是女士。
3. The books left are for my students.剩下的书是给我的学生的。
②动词-ed形式短语作定语时,通常要放在被修饰的名词的后面,在意思上相当于一个定语从句。及物动词的过去分词作定语用来表示被动,可改为带被动语态的定语从句;不及物动词的过去分词(仅限于单个过去分词,且不能后置)则表示完成,可改为带有完成时态的定语从句。
1. Is there anything planned for tonight? 今晚有什么活动吗? (=that has been planned for tonight)
2. The meeting, attended by a lot of people, was a success.这次会议有很多人出席,开得很成功。 (=which was attended by a lot of people)
3.We drank some boiled water (=which had boiled )and went on with our work.我们喝了一些开水后就继续工作。
注意:这里的过去分词的逻辑主语应是被修饰的词,改为定语从句时关系代词应与之一致。
初一英语知识点总结：动词-ed形式作表语
过去分词作表语并无“完成”或“被动”之意，而是表示主语的状态或思想感情等。如：
He looked worried after reading the letter.看完信后,他显得很忧虑。
When we heard of it, we were deeply moved.当我们听到这件事时,被深深地感动了。
He seemed quite delighted at the idea.听到这个想法,他似乎很高兴。
常见的作表语的过去分词有:
amused(愉快的); broken(碎了的);closed(关闭的);astonished(吃惊的);crowded(拥挤的);experienced(有经验的); delighted(高兴的);lost(丢失的);gone(遗失的);disappointed(失望的);worried(担忧的);interested(感兴趣的) tired(疲劳的) pleased(高兴的);satisfied(满意的); surprised(吃惊的); married(已婚的); known(著名的) 等等
初一英语知识点总结：动词-ed形式作宾语补足语
能用作宾语补足语的过去分词一般都是及物动词,表示被动意义或已完成意义,有时候两者兼而有之。作宾语补足语的过去分词与宾语有逻辑上的动宾关系,即宾语是过去分词动作的对象。
She found the door broken in when she came back.她回来时发现有人破门而人。
My grandfather had his old house rebuilt.我爷爷找人重修了一下他的旧房子。
少数不及物动词的过去分词用作宾补时,强调动作完成后的状态.
They found all the guests gone when they woke up.当他们醒来时,发现所有的客人都走了。
动词-ed形式作宾语补足语的基本用法
动词的-ed形式可以在“主语+谓语+宾语+宾语补足语”句型中充当宾语补足语。在这一结构中,动词-ed形式和它前面的宾语构成逻辑上的被动关系。如果这种句子改为被动语态,原来的宾语补足语变成了主语补足语。
1. I must get my bike repaired.我必须请人修理自行车。(宾语补足语)
2. The girl was found beaten black and blue.人们发现那女孩被打得青一块紫一块。(主语补足语)
(1)动词-ed形式可作表示感觉和心理状态的动词的宾语补足语,这类动词包括see, hear, watch, notice, feel, find, think, suppose, consider等。
We thought the game lost.我们认为球赛输了。
I have never heard him spoken ill of others.我从未听过有人说他的坏话。
They considered the matter settled.他们认为这问题解决了。
(2)动词-ed形式可作使役动词的宾语补足语,这类动词包括make, get, have, keep, leave, hold等。
I have my hair cut once a month.我每个月理一次发。
He was trying to make himself understood.他正努力使别人听懂自己。
“have+宾语+done”结构有三个含义：
①(请人)把某事做完。She had her house repaired.她请人把屋子修好了。
Where did you have your hair cut?你在哪儿理的发?
②遭遇某种意外情况。He had his hat blown away on his way home.在回家的路上他的帽子被吹掉了。
She had her wallet stolen yesterday.昨天她的钱包被偷了。
③完成某事(自己也可能参与)。I have had all my spelling mistakes corrected.我把所有的拼写错误都改正了。
He has had one thousand yuan saved this year.他今年已存了1000元。
(3)动词-ed形式可作表示希望、要求、命令等动词的宾语补足语，这类动词包括like，want, wish, expect, order等”这一类动词的后面作宾语补足语。
He won’t like such questions discussed at the meeting.他不喜欢在会议上讨论这样的问题。
The students wish the TV serial plays continued.学生们希望电视连续剧继续播下去。
(4)过去分词用在“with+宾语+宾补”这一结构中,过去分词与宾语之间是动宾关系。
The thief was brought in with his hands tied behind his back.小偷被带进来了,双手被反绑在后面。
初一英语知识点总结：过去分词作状语
1.过去分词作状语表示被动或完成，但有些过去分词(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: lost (迷路); seated (坐); absorbed in (全神贯注于); dressed in (穿着); tired of (厌烦)等。如：
Absorbed in deep thought, he didn’t hear the sound.因为沉浸在思考之中,所以他没听到那个声音。
2.过去分词作状语来源于状语从句，在句中一般能作五种状语，即时间、原因、条件、让步和方式状语。如：
Caught in a heavy rain, he was all wet.因为淋了一场大雨，所以他全身湿透了。
(Caught in a heavy rain相当于原因状语从句Because he was caught in a heavy rain)
Grown in rich soil, these seeds can grow fast.如果种在肥沃的土壤里，这些种子能长得很快。
(Grown in rich soil相当于条件状语从句If these seeds are grown in rich soil)
注意：
①当从句的主语与主句的主语一致时，才可以把从句的主语省略，且省略掉的主语与其逻辑谓语是被动关系或如第一段中所讲的表示状态。
②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，即“while (when, once, until, if, though等连词)+过去分词”结构。如：
When given a medical examination, you should keep calm.当你做体格检查时要保持镇定。
Though beaten by the opposite team, the players didn’t lose heart.
尽管这些球员被对方球队打败了，但他们并没有灰心。
