一般來說,-ing形式表示主動、進行;過去分詞表示被動、完成。試比較:The

enemy

fled

in

a

panic,

leaving

behind

a

lot

of

dead

bodies

and

weapons.Defeated

and

frightened,

the

enemy

fled

in

a

panic.分析:前一例中的-ing形式短語在句子中作伴隨狀語,它與其邏輯主語the

enemy之間為主動關(guān)系;后一句中的過去分詞defeated和frightened表原因,它與其邏輯主語the

enemy之間為被動關(guān)系。（二）分詞(短語)作狀語時，其邏輯主語必須與句子的主語一致。如果不一致，必須用獨立主格結(jié)構(gòu)來表示，也就是在分詞前面加上它的邏輯主語。1.Comparingallthegreatpeoplewitheachother,you’llfindthattheyhavemuchincommon.2.Findinghercarstolen,shehurriedtoapolicemanforhelp.3.Thetrainhavinggone,wehadtowaitanotherday.分析:前兩例中,-ing形式的邏輯主語均為主句的主語。最后一例中havinggone的邏輯主語是thetrain。（三）-ing形式的否定式。其基本結(jié)構(gòu)是:not+-ing形式,無論在完成式還是被動式里,not必須置于-ing形式之前。如:Nothavingfinishedhishomework,theboywasstilldoingitintheclassroom.

（四）

-ing形式(短語)的功能有時相當(dāng)于一個狀語從句。

根據(jù)這個性質(zhì),我們在使用-ing形式作狀語時,切記不要在前面或后面的句子前用連詞連接。如:Walking

on

the

fallen

leaves

in

autumn,

so

you’ll

feel

very

comfortable.(×)分析:如前所述,-ing形式短語相當(dāng)于一個狀語從句,所以后半句中的連詞so的使用是錯誤的,應(yīng)該去掉。原句應(yīng)改為:

Walking

on

the

fallen

leaves

in

autumn,

you’ll

feel

very

comfortable.Exercises請用括號里所給動詞的適當(dāng)形式填空:1._____(live)inasoutherncityofChina,Ihaveneverseensuchawonderfulsnowview.2._____(notgrow)upyet,you’renotallowedtoenterthebars.3._____(encourage)bythedirector,theactorsperformedwonderfullyintheplay.4._____(Know)allthis,theymademepayforthedamage.5.Thestudentsaresittinginthereading-room,_____(r
