第一步检查作业
1.提问学生上节课所学的知识点。
2.Letstudentsretellthetextinthefirstperson.
3.Lettwostudentsgivetheirtalksontheirchosenscientisttotheclass.
第二步导入语法
翻译下列句子并注意过去分词的用法:
1.MostofthescientistsinvitedtothepartywerefromSouthAmerica.
2.Harvard,foundedin1636,isoneofthemostfamousuniversitiesintheUnitedStates.
3.Yourmotherisverydisappointedwithyou.
4.Thetopofthemountainiscoveredwithsnow.
让学生知道前两个句子中过去分词是作定语,后两个句子中过去分词是作表语,从而引出过去分词作定语和表语的教学。
第三步讲解过去分词作定语和表语的用法
过去分词兼有动词、副词和形容词的特征,可以带宾语或受状语修饰。过去分词和宾语或状语一起构成过去分词短语。它在句中可以作定语、表语、宾语补足语或状语。这节课讲解作定语、表语的用法。
1.作定语
作定语的过去分词如果是单词,一般放在被修饰词的前面;过去分词短语作定语,一般放在被修饰词的后面。例如:
Therearemanyfallenleavesontheground.
Thisisabookwrittenbyaworker.
2.作表语
过去分词作表语,多表示主语所处的状态。
Iwaspleasedatthenews.
Thedoorremainedlocked.
过去分词作表语,相当于形容词,常见的有:
delighted,disappointed,astonished,interested,satisfied,surprised,tired,worried,excited,married等。
过去分词作表语时,应注意与被动结构的区别。系表结构说明主语的状态或具有的性质、特点;被动结构强调谓语动作。
Thesmallvillageissurroundedbytrees.(状态)
Thesmallvillagewassoonsurroundedbyenemysoldiers.(动作)
Iminterestedinchess.(状态)

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:
anhonoredguest一位受尊敬的客人
Theinjuredworkersarenowbeingtakengoodcareofinthehospital.
受伤的工人现正在医院受到良好的照料。
B类:完成意义:
aretiredteacher一位退休的教师
Theyarecleaningthefallenleavesintheyard.
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:Thiswillbethebestnovelofitskindeverwritten(=thathaseverbeenwritten).这将是这类小说中写得最好的。
Whoweretheguestsinvited(=whohadbeeninvited)toyourpartylastnight?
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:
Helookedworriedafterreadingtheletter.看完信后,他显得很忧虑。
Whenweheardofthestory,weweredeeplymoved.当我们听到这个故事时,被深深地感动了。
Heseemedquitedelightedattheidea.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);connected(连接的);broken(碎了的);closed(关闭的);astonished(吃惊的);covered(覆盖的);crowded(拥挤的);delighted(高兴的);disappointed(失望的);dressed(穿着的);drunk(喝醉的);experienced(有经验的);gone(遗失的);lost(丢失的);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。
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:
Myglassesarebroken.我的眼镜碎了。(状态)
Myglasseswerebrokenbymydaughter.我的眼镜被我女儿摔碎了。(动作)
Ontheearth,70%ofthesurfaceiscoveredwithwater.地球表面70%是被水覆盖的。(状态)
Iwasgreatlysurprisedbyaknockatthedoor.敲门声使我大为吃惊。(动作)
