34、onoured guest. 這位老人是一位貴賓。 most of the people invited to the conference were my old friends.大多數(shù)被邀請(qǐng)參加會(huì)議的人都是我的老朋友。2）如果單個(gè)的過去分詞所修飾的詞是代詞those或是由some / any / no / every + thing / body / one所構(gòu)成的不定代詞時(shí)，通常過去分詞要放在被修飾的詞之后。如：there is almost nothing changed since i left the town two years ago.自從我兩年前離開以來，這個(gè)鎮(zhèn)幾乎沒有什么變

35、化。3）一般來說，a)及物動(dòng)詞的過去分詞作定語時(shí)，表示一個(gè)被動(dòng)的、已完成的動(dòng)作；b)不及物動(dòng)詞的過去分詞作定語時(shí)，只表示完成，不表示被動(dòng)意義。如：a damaged bridge 一座被毀壞的橋 polluted air and water 被污染的空氣和水fallen leaves 落葉 a retired teacher 一位退休的教師2、過去分詞作表語1）表示主語的特點(diǎn)或所處的狀態(tài)，其前可有quite, very, rather等修飾詞。如:when he came to the door of his house, he found the door was locked.當(dāng)他到達(dá)家門

36、口的時(shí)候，他發(fā)現(xiàn)門是鎖著的。he seemed quite delighted at the idea.聽了這想法他似乎很高興。2） 過去分詞作表語時(shí)，系動(dòng)詞除了是be之外，還可以是appear, feel, remain, seem, look, sound, get, become等。如：he appeared very satisfied with the result of the exam. 他好像對(duì)這次考試結(jié)果很滿意。the children looked very puzzled when they heard what the teacher said just now.孩子們

37、聽了老師剛才講的話看起來很困惑。3) 作表語的過去分詞主要來自及物動(dòng)詞, 少數(shù)不及物動(dòng)詞(如go, come等)的過去分詞作表語時(shí), 不表示被動(dòng)意義, 只表示動(dòng)作的完成。如: they are gone for vacation. 他們度假去了。3、過去分詞作賓語補(bǔ)足語1）所表示的動(dòng)作和賓語有邏輯上的動(dòng)賓關(guān)系。如：you should raise your voice to make yourself heard. 你應(yīng)該大聲點(diǎn), 以便讓別人聽見。2）跟過去分詞作賓語補(bǔ)足語的詞可以是表示感覺或思維活動(dòng)的動(dòng)詞(短語)，如: see, watch, observe, notice, look at

38、, hear, listen to, find, feel, think, consider等。如：when he returned, he found his room thoroughly cleaned. 他回來的時(shí)候, 發(fā)現(xiàn)自己的房間已被徹底打掃了。3）跟過去分詞作賓語補(bǔ)足語的詞可以是表示“致使”意義的動(dòng)詞，如：have, make, get, keep, leave等。如：he couldnt keep his eyes shut to all this. 他不能對(duì)這一切視而不見。4) 跟過去分詞作賓語補(bǔ)足語的詞可以是表示“愛憎”、“要求”、“意愿”等意義的動(dòng)詞，如：like, ha

39、te, order, want, wish, expect等。如：i wish my homework finished before five oclock.我希望五點(diǎn)前完成我的作業(yè)。5) 除了動(dòng)詞外，介詞with也可跟過去分詞作賓語補(bǔ)足語。如：the great writer died with his works unfinished. 這位偉大的作家去世時(shí)，他的著作還沒有完成。.summary一、 動(dòng)詞-ed形式作定語過去分詞作定語往往與被修飾的詞靠得很緊, 漸漸地成為一個(gè)復(fù)合詞。這種分詞叫分詞形容詞 (the participle adjective), 實(shí)際上相當(dāng)于一個(gè)單純的形容詞

40、, 除表示“完成”的動(dòng)作之外, 還表示“被動(dòng)”的意義。如：spoken english (英語口語)；iced beer (冰凍啤酒)；cooked food (熟食); fried chips (炸土豆條); 但要注意不及物動(dòng)詞的過去分詞常表示“完成”的動(dòng)作, 而不表示“被動(dòng)”意義。如: boiled water(開水); fallen leaves(落葉) ; the risen sun(升起的太陽)等。1.the tall man is a returned student高個(gè)子的那個(gè)人是個(gè)歸國(guó)留學(xué)生。2. my parents are both retired teachers 我的父

41、母都是退休教師。(一) 前置定語單個(gè)的動(dòng)詞-ed形式,一般放在被修飾的名詞的前面, 作前置定語。 the excited people rushed into building. 激動(dòng)的人們沖進(jìn)大樓。 (=the people who were excited) lost time can never be found again 虛度的時(shí)光, 無法挽回。 (=time which is lost)(二) 后置定語少數(shù)單個(gè)動(dòng)詞的-ed形式, 如left等, 只能作后置定語。 1. everything used should be marked 所有用過的東西應(yīng)該做好標(biāo)記。 2. among

42、the invited were some ladies 被邀請(qǐng)的人中, 有些是女士。 3. the books left are for my students 剩下的書是給我的學(xué)生的。動(dòng)詞-ed形式短語作定語時(shí), 通常要放在被修飾的名詞的后面, 在意思上相當(dāng)于一個(gè)定語從句。及物動(dòng)詞的過去分詞作定語用來表示被動(dòng),可改為帶被動(dòng)語態(tài)的定語從句;不及物動(dòng)詞的過去分詞(僅限于單個(gè)過去分詞,且不能后置)則表示完成,可改為帶有完成時(shí)態(tài)的定語從句。 1. is there anything planned for tonight? 今晚有什么活動(dòng)嗎? (=that has been planned for

43、 tonight)2. the meeting, attended by a lot of people, was a success這次會(huì)議有很多人出席, 開得很成功。 (=which was attended by a lot of people)3. we drank some boiled water(=which had boiled )and went on with our work.我們喝了一些開水后就繼續(xù)工作。注意:這里的過去分詞的邏輯主語應(yīng)是被修飾的詞, 改為定語從句時(shí)關(guān)系代詞應(yīng)與之一致。當(dāng)堂檢測(cè)一：1. most of the artists_ to the party
