(1)Seenfromthehill,thecitylooksmagnificent.Seeing

byhisexample,theyperformedcountlessgooddeeds.

Hesatatthetable,readingamagazine.【探究總結(jié)】過去分詞與其邏輯主語之間是被動關(guān)系,往往表示完成;動詞-ing形式與其輯主語之間是主動關(guān)系,一般表示動作正在進(jìn)行。【注意】1.過去分詞作狀語,它的邏輯主語必須和句子的主語相一致。e.g.Ifcaught,thepolicewillpunishthethief.[誤]

Ifcaught,thethiefwillbepunishedbythepolice.

[正]

小偷如果被抓,會受到警方的懲罰。2.過去分詞作狀語時,其前面可以帶有相應(yīng)的連詞,如when,though,although,asif,if,unless,until,once等,表時間、讓步、條件方式等。e.g.If(Iam)invited,Iwillattendtheweddingofmyfriend.

如果受到邀請,我會參加我朋友的婚禮。v.-ed和v.-ing形式作表語時：v.-ed與其邏輯主語之間是被動關(guān)系。v.-ing與其邏輯主語之間是主動關(guān)系。v.-ed和v.-ing形式作狀語時：如果句子的主語和分詞是被動關(guān)系，時間已經(jīng)完成用v.-ed形式。如果句子的主語和分詞是主動關(guān)系，時間正在發(fā)生用v.-ing形式。1.…Andwhenhesawthemistsrisingfromtheriverandthesoftclouds____________(surround)themountaintops,hewasreducedtotears.
