For reference:現(xiàn)在分詞和過去分詞的用法 現(xiàn)在分詞和過去分詞主要差別在于：現(xiàn)在分詞表示“主動和進行 ”，過去分詞表示“被動和完成”(不及物動詞的過去分詞不表示被 動，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，可以表示時間、條件、原 因、結果、讓步、伴隨等。分詞做狀語時，它的邏輯主語與句子 的主語一致。作狀語的分詞相當于一個狀語從句。 e.g:Hearing the news, they all jumped with joy. 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 的關系：主謂關系用現(xiàn)在分詞，動賓或被動關系用過去分詞。. No matter how frequently __, the works of Beethoven always attract large audiences. (CET-4 19) A. performing    B. performed   C. to be performed    D. being performed 2)“while ( when, once, until, if , though等連詞)＋分詞”結構現(xiàn)在分 詞或過去分詞作狀語時，有時可以在分詞前加while，when, once , although, until, if等連詞。 e.g:When leaving the airport, she waved again and again to us. 3)分詞作定語時，單個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?，F(xiàn)在分詞修飾的是發(fā)出該動 作的名詞(即與名詞有主謂關系),過去分詞修飾承受該動作的名詞 (即與名詞是動賓關系)。e.g:.As early as 1649 Ohio made a decision that free, tax-supported schools must be established in every town ___50 households or more. (CET-4 1998,1) 　A) having   B) to have    C) to have had    D) having had 4)分詞作賓語補足語現(xiàn)在分詞在see, watch, hear, observe, notice, feel, find, glimpse, glance等感官動詞和look at, listen to等短語動 詞以及have, keep, get, catch, leave, set, start, send等使役動詞后與 名詞或代詞構成復合賓語，作賓語補語的成分。e.g:On the top of the hill, we could see smoke rising from the chimneys in the village. 過去分詞可以在allow, ask, consider, desire, expect, feel, find, get, have, hear, imagine, keep, like, make, observe, order, permit, prefer,, remember, request, require, see, urge動詞等后面作賓語補足語。 e.g:After my encounter with her, I found myself greatly shaken. 在動詞see, hear, feel, watch, notice，perceive，observe, listen to, look at后既可用現(xiàn)在分詞做補語,也可用不定式做補語。用現(xiàn)在 分詞表示動作正在進行,用不定式表示的動作的全過程已經(jīng)完成. e.g:I saw Mr. White looking into a shop window. 5)分詞作表語 分詞作表語通?？醋餍稳菰~來用?，F(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。e.g:The film “Pearl Harbor” is really exciting.
