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.

homework:
