現在分詞在英語這壹科目中，也是比較重要的壹部分，具有雙重性，壹面具有動詞的特征，可以有自己的賓語和狀語；另壹面具有形容詞和副詞的特征，可以充當表語，定語，狀語，補足語，可以表示主動或正在進行的動作，是非謂語動詞的壹種。
分詞是動詞的三種非謂語形式之壹，分為現在分詞和過去分詞。現在分詞的形式由動詞原形加詞尾-ING構成，過去分詞的形式分為規則變化和不規則變化，規則變化是在動詞原形後加-ED，不規則變化要單獨記憶，如：rot—rotted—rotten、sink—sank—sunk、strike—struck—struck、bear—bore—borne、get—got—gotten、hang—hung—hung。
分詞也具有動詞的特征，有時式和語態的變化，並可以帶狀語或賓語，分詞的否定式是在分詞前加not。如：
Having hurried through his breakfast, he went to wait for the school
bus.
The problem being discussed now is our quarterly meeting.
Having been working here for four and a half years, I have no time for other
things.
Having been written in haste, the paper is full of mistakes.
When asked such a queer question, he was
at a loss how to answer it.
Not wanting to continue my service in the plant, I joined the army.
及物動詞的現在分詞的主動式，在時間上表示正在進行的動作，在語態上表示主動意義；及物動詞的過去分詞在時間上表示動作的完成，在語態上表示被動意義。如：
a refreshing breeze
feel refreshed
a frightening scene
a frightened child
a disappointing matter
a disappointed look
現在分詞表示動作正在進行或壹般現在時的概念，過去分詞表示動作已經完成，不壹定有被動意義，如：
falling leaves
fallen leaves
boiling
water
boiled
water
不及物動詞come和連系動詞become的過去分詞要後置。如：
a former teacher become a lover
a god come down to the earth
He was a young carpenter come from the USA.
