过去分词作定语、表语和宾语补足语
一、过去分词作定语
　　过去分词作定语时往往与被修饰的词靠得很近，渐渐地成为一个复合词。这种分词叫分词形容词 (the Participle Adjective)，实际上其作用相当于一个形容词，除表示“完成”的动作之外，还表示“被动”的意义。
语法归纳
　　助记
　　分词作定语的位置及其他：
　　“定分”位置有两个，词前词后定分晓。
　　单个分词在词前，有时此规有颠倒。
　　分词短语在词后，“定从”和它互对照。
　　“现分”动作进行时，“过分”动作完成了。
　　(注：“定分”即作定语的分词；“定从”即定语从句；“现分”即现在分词；“过分”即过去分词。)
语法归纳
1．前置定语
　　单个的v.?ed形式，一般放在被修饰名词的前面，作前置定语。
　　The excited people (＝The people who were excited) rushed into the building.
　　激动的人们冲进了大楼。
　　Lost time (＝Time which is lost) can never be found again.
　　逝去的时光无法再找回。
语法归纳
　　2．后置定语
　　(1)修饰不定代词的过去分词应放其后，少数单个v.?ed形式，如left等，只能作后置定语。
　　Everything used should be marked.
　　每一个用过的东西都应该做上标记。
　　The books left are for my students.
　　剩下的书是给我的学生们的。
语法归纳
　　 (2)v.?ed短语作定语时，通常要放在被修饰名词的后面，相当于一个定语从句。
　　Is there anything planned for tonight (＝that has been planned for tonight)?
　　今晚有什么计划好的事情吗？
　　The meeting, attended by a lot of people (＝which was attended by a lot of people), was a success.
　　这次会议开得很成功，有很多人出席。
语法归纳
[温馨提示] (1)不及物动词的过去分词常表示“完成”的动作，而不表示“被动”的意义。如：
　　falling leaves正在飘落的叶子(表正在进行)
　　fallen leaves落叶(表完成)
　　the exploded bomb已爆炸的炸弹
　　a retired miner已退休的矿工
　　the risen sun升起的太阳
　　
语法归纳
　　(2)learn, light都有两种形式的过去分词，但作定语时，只能用拼写较长的过去分词。
　　a learned lawyer一位博学的律师
　　a lighted lamp一只点亮的灯
语法归纳
　　二、过去分词作表语
　　过去分词作表语时，总是在系动词(如be，appear，feel，remain，seem，look等)之后，构成系表结构。特别要注意在与be连用时，要注意区分是“系表结构”还是“被动语态”，作表语的过去分词表示状态，而被动语态中的过去分词表示动作。
　　
语法归纳
　　All the doors are locked.
　　所有的门都是锁着的。
　　He felt thoroughly broken down.
　　他觉得身体彻底垮了。
　　The children looked puzzled.
　　孩子们看起来迷惑不解。
语法归纳
　　三、过去分词作宾语补足语
　　过去分词可以在“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，v.?ed形式和它前面的宾语构成逻辑上的被动关系。
　　I must get my bike repaired.
　　我必须请人把我的自行车修好。(宾语补足语)
　
语法归纳
　　1．过去分词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.我们以为比赛输了。
　　I have never heard him spoken ill of by others.
　　我从未听过别人说他的坏话。
　　They considered the matter settled.
　　他们认为这个问题解决了。
语法归纳
　　2．过去分词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.
　　我一个月理一次发。
　　He is trying to make himself understood.
　　他正努力让别人理解自己(的话)。
　　She held her hands pressed against her face.
　　她用双手捂着脸。
语法归纳
[温馨提示] “have＋宾语＋done”结构有三层含义：
　　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？
　　
语法归纳
　　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走了。
　　She had her wallet stolen yesterday.
　　昨天她的钱包被偷了。
　　
语法归纳
　　③完成某事 (自己也可能参与)。
　　I have had all my spelling mistakes corrected.
　　我已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。
语法归纳
　　3．过去分词可作表示希望、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。
　　He won't like such questions discussed at the meeting.
　　他不喜欢在会上讨论这样的问题。
　　The students wish the serial continued.
　　学生们希望电视连续剧继续播下去。
语法归纳
　　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,双手被绑在后面。

　　[导读] 自我们在《回到未来》(Back to the Future)这部电影中看到马蒂?麦克弗莱(Marty McFly)的耐克鞋自动系鞋带的神奇情景，已有二十多年了。
延伸拓展阅读
　　A team of scientists from University of Freiburg in Germany are developing a shoe with a sensor to automatically tie its laces that could be taken off when users click their heels together.
　　①It's been more than twenty years since we saw them magically tightening Marty McFly's Nike boots in Back to the Future.
　　Now, self?tying shoelaces could actually become a reality this year, proving right one of the film's fantastical predictions for what 2018 would be like.
　　
延伸拓展阅读
　　②Engineers have designed a shoe that can automatically lace up, adjusting itself to the shape of your foot.Simply slip the trainer on and pressure sensors will tell the “smart shoe” when your foot is in position, triggering a tiny motor in the heel that pulls the laces tight.
　　When you want to take off the shoes, you click your heels together twice and the motor will release a spring in the shoe's tongue, which loosens the laces enough for you to slip them off.
　　
延伸拓展阅读
　　 And the ingenious invention doesn't even need to be plugged in to charge or have its battery replaced because it runs on power generated by the swing of your foot as you walk.
Engineer Klevis Ylli, of the Institute for Micromachining and Information Technology in southern Germany, said the shoes could help a variety of different people.
　　“One focus is that it could be used in shoes for elderly people who have mobility problems，”he said. “But it could also work for children, or as a lifestyle product.”
　　
延伸拓展阅读
　　The design, which is still in a prototype phase, cleverly captures the energy of the foot's swing when opposing magnets in each shoe move past each other.
It then uses that power to charge a battery. An hour of walking is enough to tighten the laces once, and it requires no energy to undo the shoes because that relies on the spring alone.

　　②Engineers have designed a shoe that can automatically lace up, adjusting itself to the shape of your foot.
　　句意：工程师们设计出一款可以自动系鞋带的鞋，这款鞋可根据脚型进行自动调节。
　　赏析：that引导的是一个定语从句，adjusting itself to the shape of your foot为现在分词短语作伴随状语，表主动。
