Unitedwestand,dividedwefall.Seen

fromthetopoftheTigerHill,thecityofSuzhouwasverybeautiful.三、过去分词形式作宾补作宾补时，过去分词常用于使役动词have,get,make,keep和感官动词see,watch,hear等动词的宾语后面，表达谓语动词引起的宾语的变化，或补充说明宾语的性状。e.g.Owengothisnosehurtwhenheplayedfootballwithhisteammates.Iheardthedoorpulledopen.四、过去分词形式作表语1.完全形容词化了的动词-ed形式可以被very等副词修饰，可以有比

较级等级形式。常见的有：bored,disappointed,excited,frightened,interested,pleased,puzzled,satisfied,surprised,tired,worried等。2.有的动词-ed形式可以被副词well修饰，如：built,cooked,done,dressed,known,prepared,written等。3.其它副词也可以修饰动词-ed形式，如：deeplymoved,highlydeveloped,heavilypopulated等。4.动词-ed形式作表语时，其后可以接介词短语、不定式短语及that

引导的宾语从句。目标二：TomastertheuseofpastparticipleinthespecificcontextActivity1:Fillintheblankswiththehelpofthebeginningletters.Thenrewritethesentenceswithoutusingpastparticiplesandrecognisethedifference.1.D______into32counties,Irelandbringsinhundredsofthousandsofvisitorseachyearduetoitsgolftourism.2.CubaisjustsouthofAmerica,s_________fromitonlybytheStraitsofFlorida.Itisacountryk_______foritsexcitingmusicanddancing.3.Withmanypartsoftheworldnotm______yet,researchershavebegunaprojectthatinvolvestravellingaroundtheworldandtakingsamplephotographs.ividedeparatednownapped4.I__________bythefirstEuropeansettlerstoAustralia,theSundayroastisnowconsideredtypicalAustralianfood.5.E________tothefreezingweather,manybravetouristsandscientistsstillchoosetovisitAntarctica.6.I_________byChineseculture,manycapitalcitiesnowhaveChinatownwhichareinthemselvespopulartouristattractions.ntroducedxposednfluencedSuggestedAnswers1.Sinceitisdividedinto32counties,Irelandbringsinhundredsofthousandsofvisitorseachyearduetoitsgolftourism.2.CubaisjustsouthofAmericaandisseparatedfromitonlybytheStraitsofFlorida.Itisacountryfamousforitsexcitingmusicanddancing.3.Becausemanypartsoftheworldhavenotmapped,researchershavebegunaprojectthatinvolvestravellingaroundtheworldandtakingsamplephotographs.4.ThoughitwasintroducedbythefirstEuropeansettlerstoAustralia,theSundayroastisnowconsideredtypicalAustralianfood.5.Thoughtheywillbeexposedtothefreezingweather,manybravetouristsandscientistsstillchoosetovisitAntarctica.6.BecausetheyareinfluencedbyChineseculture,manycapitalcitiesnowhaveChinatownwhichareinthemselvespopulartouristattractions.visitedproposedclaimedTheEiffelToweristhemostfamouslandmarkinFrance,andoneofthemostvisitingmonumentsintheworld.Butitwasn'talwayssopopular.Infact,in1886,justafteritsconstructionwasfirstpropose,manywerestronglyagainstit.Atthattime,itwouldhavebeenthetallestbuildingint
