step2grammar
1.showaflashtoreviewthedifferencesbetweenv-ingandthepastparticiple.
a.现在分词表示主动,过去分词表示被动。
b.现在分词表示进行中的动作,过去分词表示动作已完成。
2.showaflashtoreviewthev-ingformastheadverbial.
a.分词的逻辑主语必须与主句的主语一致.
b.分词的动作不是主句的主语发出时,分词前面必须加上它的逻辑主语,这种分词短语叫做独立主格
结构.
c.当独立主格结构的逻辑主语泛指一般人,如we,you,one时,逻辑主语可以省略.
3.showthefollowingpairofsentencesonthescreen.
iwasfeelingtired.iwenttobedearly.→feelingtired,iwenttobedearly.相当于asifelttired,iwenttobedearly.
iworkedhardallday.iwenttobedearly.→havingworkedhardallday,iwenttobedearly.相当于afteriworkedhardallday,iwenttobedearly.
可以看出:
a.分词的一般式说明分词的动作与主句谓语动词的动作是同时发生的.
b.分词的完成式说明分词的动作发生在主句谓语动词的动作之前.
巩固练习:
现在分词的完成式和一般式进行互换.
a.studyingvolcanoes,iamamazedattheirbeautyaswellastheirpotentialtocausegreatdamage.→havingstudiedvolcanoesfortwentyyears,iamstillamazedattheirbeautyaswellastheirpotentialtocausegreatdamage.
b.havingstoodforseveralminutes,isawsomeofmyfriendschattingatatable.→
arrivingthere,isawsomeofmyfriendschattingatatable.
c.writingtheletter,heleftoutsomethingimportant.→
havingwrittentheletter,hereaditcarefully.
4.用分词的一般式改写句子:
asididn’tknowhowtofindthesubway,icalledapolicemanforhelp.→
notknowinghowtofindthesubway,icalledapolicemanforhelp.
可以看出:
分词的否定式是在分词短语前面加上not,never等否定词.
5.小结-ing形式的用法
7.完成36页与37页的关于分词的一般式和完成式的练习.
