英語上的分詞分為現(xiàn)在分詞和過去分詞.
現(xiàn)在分詞和過去分詞主要差別在于：現(xiàn)在分詞表示"主動(dòng)和進(jìn)行",過去分詞表示"被動(dòng)和完成"(不及物動(dòng)詞的過去分詞不表示被動(dòng),只表示完成).分詞可以有自己的狀語、賓語或邏輯主語等.
1、 分詞作狀語分詞在句子中作狀語,可以表示時(shí)間、條件、原因、結(jié)果、讓步、伴隨等.
分詞在句子中作狀語,使用何種分詞,要取決于分詞與句子主語的關(guān)系：主謂關(guān)系用現(xiàn)在分詞,動(dòng)賓或被動(dòng)關(guān)系用過去分詞.
（1）現(xiàn)在分詞The students went out of the classroom,laughing and talking.
（2）過去分詞Accompanied by his friend,he went to the railway station.Given better attention,the plants could grow better.
2、"while ( when,once,until,if ,though等連詞)＋分詞"結(jié)構(gòu)現(xiàn)在分詞或過去分詞作狀語時(shí),有時(shí)可以在分詞前加while,when,once,although,until,if等連詞.

Once recovered,he threw himself into his work and made every effort to do it well.
Although working very hard,he failed to pass the final exam.If translated word by word,the passage will be difficult to understand.
3、分詞作定語分詞作定語時(shí),單個(gè)的分詞通常放在被修飾的名詞之前,分詞短語一般置于所修飾的中心詞后面.現(xiàn)在分詞修飾的是發(fā)出該動(dòng)作的名詞(即與名詞有主謂關(guān)系),過去分詞修飾承受該動(dòng)作的名詞(即與名詞是動(dòng)賓關(guān)系).

4、分詞作賓語補(bǔ)足語現(xiàn)在分詞在see,watch,hear,observe,notice,feel,find,glimpse,glance等感官動(dòng)詞和look at,listen to等短語動(dòng)詞以及have,keep,get,catch,leave,set,start,send等使役動(dòng)詞后面與名詞或代詞構(gòu)成復(fù)合賓語,作賓語補(bǔ)語的成分.
5、分詞作表語分詞作表語通?？醋餍稳菰~來用.現(xiàn)在分詞表示主語的性質(zhì),而且主語多為物；過去分詞表示主語的感受或狀態(tài),主語多為人.
