4、 usages given here in grups r fur3 Teahers give neessar explanatin and se re general usages f the past partiiples过去分词是非谓语动词的一种形式,表示完成和被动的动作。它在句子中可以充当表语、定语等成份。下面仅谈其作定语和表语的用法。一、过去分词作定语过去分词作定语有前置和后置两种情况。 1、前置定语单个的过去分词作定语,通常放在被修饰的名词之前,表示被动和完成意义。A 类:被动意义:an hnred guest 一位受尊敬的客人The inured rers are n being
5、 taen gd are f in the hspital受伤的工人现正在医院受到良好的照料。B 类:完成意义:a retired teaher 一位退休的教师The are leaning the fallen leaves in the ard他们正在打扫院子里的落叶。2、后置定语过去分词短语作定语时,通常放在被修饰的名词之后,它的作用相当于一个定语从句。如: This ill be the best nvel f its ind ever ritten (=that has ever been ritten) 这将是这类小说中写得最好的。h ere the guests invited
6、(=h had been invited) t ur part last night?昨晚被邀请参加你的晚会的那些客人是谁呀?二、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。例如： He led rried after reading the letter 看完信后，他显得很忧虑。 hen e heard f the str, e ere deepl ved 当我们听到这个故事时，被深深地感动了。 He seeed 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：aused (愉快的)； nne
7、ted (连接的)； bren (碎了的)； lsed (关闭的)；astnished (吃惊的)； vered (覆盖的)； rded (拥挤的)； delighted (高兴的)； disappinted (失望的)； dressed ( 穿着的)； drun (喝醉的)；experiened (有经验的) ； gne (遗失的)；lst (丢失的)； rried (担忧的)；interested (感兴趣的)； tired (疲劳的)； pleased (高兴的)； satisfied (满意的)； surprised (吃惊的)； arried (已婚的)； nn (著名的)，等等。
8、注：过去分词作表语不要与被动语态混为一体。分词作表语表示主语的状态，而被动语态则表示被动的动作。例如： glasses are bren 我的眼镜碎了。(状态) glasses ere bren b daughter 我的眼镜被我女儿摔碎了。(动作) n the earth, 70% f the surfae is vered ith ater 地球表面 70%是被水覆盖的。(状态) I as greatl surprised b a n at the dr 敲门声使我大为吃惊。(动作) 第四步 巩固应用 （小组竞赛） Page44 Using strutures1 As students t
