一、概念 动词-ed形式是动词的一种非限定形式，由动词done构成。具有形容词，副词的作用，在句中可以作定语、表语、状语或宾语补足语。 二、语法规则 (一)作定语 及物动词的-ed形式通常表示被动和完成意义；不及物动词的-ed形式仅仅表示完成。 1．前置定语 单个的动词-ed形式作定语一般放在被修饰的名词之前。 He is a respected teacher in our school. 在我们学校他是一位受尊敬的老师。 2．后置定语 动词-ed形式短语作定语通常要置于被修饰的名词之后。 This is a letter written in blue ink. 这是一封用蓝墨水写的信。 [名师点津]　(1)如果被修饰词是由some/any/no＋thing/body/one构成的不定代词或指示代词those等时，即使是单个的动词-ed形式作定语，也要放在被修饰词之后。 There is almost nothing changed since I left the town two years ago. 自从我两年前离开这个镇以来，几乎没有什么变化。 (2)有时为了强调还可将单个的动词-ed形式置于被修饰的名词之后。 They decided to change the material used. 他们决定改变所用的材料。

students. ③The book，_______(write)by Lu Xun，is popular with many Chinese people. ④Do you remember the problems _________(discuss) at the last meeting? (二)作状语 动词-ed形式作状语，其逻辑主语是句子的主语，与主语是被动关系。动词-ed形式作状语可以表示时间、原因、条件等，有时可带有连词。 1．作时间状语 When offered help，one often says “Thank you” or“It's kind of you”． 当被提供帮助时，人们常说“谢谢你”或“你真好”。 2．作原因状语 Praised in class，Anne felt happy. 在课堂上受到了表扬，安妮感到高兴。 3．作条件状语 If taken according to the directions，the drug has no side effects. 如果按照说明服用，这种药没有副作用。 4．作伴随状语 The teacher came into the lab，followed by some students. 老师进了实验室，后面跟着一些学生。 [名师点津]　动词-ed形式作时间、原因和条件状语时均可以转换成相应的状语从句。 [对点集训2] 单句语法填空 ①______(raise)in the poorest area of Glasgow，he had a long，hard road to become a football star. ②__________(approach)in this way，your friendship will soon be repaired. ③The lady returned home，________(follow)by Holmes. (三)作宾语补足语 作宾补的多是及物动词-ed形式，说明宾语的状态或性质，与宾语一起构成复合宾语，前面的宾语就是其逻辑主语。 1．以下两类动词后可接动词-ed形式作宾补 (1)表示感觉或心理状态的动词。如：see，watch，observe，find，hear，feel，notice，think等。 ①I heard the song sung in English. 我听到有人用英语唱过这首歌。 ②He found his purse lost. 他发现他的钱包丢了。 (2)表示“致使”意义的动词。如：have，make，get等。 ③I'll have my hair cut tomorrow. 明天我要理发。 ④He got his tooth pulled out yesterday. 他昨天把牙拔了。 2．动词-ed形式作宾补表示的意义 (1)表示被动关系，其动作先于谓语动词所表示的动作。如例句②，lost表示的动作显然先于谓语动词found。 (2)表示的动作一定和宾语有逻辑上的动宾关系。如例句③及④中cut my hair和pull out his tooth是动宾关系。 [名师点津]　(1)使役动词have接动词-ed形式作宾补，还有两种情况： ①动词-ed形式所表示的动作由他人完成。 He had his money stolen. 他的钱被偷了。(被别人偷去了) ②动词-ed形式表示句子主语的经历。 He had his leg broken. 他的腿断了。(句子主语的经历) (2)在with/without复合结构中也可用动词-ed形式作宾补。 With this sum added，we will have enough money for the trip. 如果加上这笔金额，我们这次旅行的钱就够了。 [对点集训3] 完成句子 ①The villagers ______________________ then. 村民们那时种了很多树。 ②However tired I am，I must _____________________． 无论多累，我必须把这份工作干完。 ③She still couldn't _______________________ in English. 她依然不能用英语表达出自己的意思。 ④She ____________________ by policemen. 她看见小偷被警察抓住了。 Ⅰ.单句语法填空 1．In the 1970s，the Chinese made a great _________(discover)，which later saved millions of people. 2．We students have a _______(medicine) examination twice every year. 3．This book is ____ I was looking for all the time. 4．And when he saw the mists rising from the river and the soft clouds ___________ (surround) the mountain tops，he was reduced to tears. 5．The light is still on in his office.Perhaps he __________ (work) on the new plan. 6．The teachers are making every effort to get the students ________ (prepare) for the coming examinations. 7．He invited some scientists ___ are interested in his research. 8．The telephone is considered to be ___ of the most useful inventions. 9．_____ he left the village，he has worked in Shenzhen for 30 years. 10．He has bought a new computer and has found many of ___(it) new functions.
