21、于過去，說明了是現(xiàn)在的情況-燈現(xiàn)在不亮了。）現(xiàn)在完成時(shí)”完成用法”的特點(diǎn)是動作不延續(xù)，即瞬間動詞，因此，該時(shí)態(tài)只能與表示不定的過去時(shí)間狀語（如：already，yet，before，recently 等）、頻度時(shí)間狀語（如：never，ever，once 等）、包括現(xiàn)在時(shí)刻在內(nèi)的時(shí)間狀語（如：this morni ng / mon th / year., today等）連用。例如：Have you found your pen yet ?你已找到你的鋼筆了嗎？2. 現(xiàn)在完成時(shí)的"未完成用法”現(xiàn)在完成時(shí)的”未完成用法”指的是動作開始于過去某一時(shí)刻，一直延續(xù)到現(xiàn)在，或可能還要繼續(xù)下去。例

22、如：He has lived here si nee 1978.自從1978年以來，他一直住在這兒。（動作起始于 1978年，一直住到現(xiàn)在，可能還要繼續(xù)住下去。）I have been in the army for more than 5 years.我在部隊(duì)已經(jīng)呆了五年多了。（動作開始于5年前， 一直延續(xù)至今，有可能還要繼續(xù)下去。）此種用法的句中常需一個(gè)表示一段時(shí)間的狀語（由since或for引導(dǎo)）,或表示與現(xiàn)在時(shí)刻相連的時(shí)間狀語（如：up to now , so far到目前為止）等。例如：I have heard nothing from him up to now.到目前為止我沒有他

23、的任何消息。注意：現(xiàn)在完成時(shí)的未完成用法只適用于延續(xù)性動詞，不可用于終止性動詞，即瞬間完成或延續(xù)時(shí)間很短的動詞。3. 延續(xù)性動詞和瞬間性動詞的概念英語中，動詞按其動作發(fā)生的方式、動作發(fā)生過程的長短，可分為延續(xù)性動詞 和瞬間性動詞。延續(xù)性動詞表示能夠延續(xù)的動作，這種動作可以延續(xù)下去或產(chǎn)生持久影響。女口： learn, work, stand, lie, know, walk, keep, have, wait, watch, sing, read, sleep, live, stay 等。瞬間性動詞也稱非延續(xù)性動詞、瞬間動詞或短暫性動詞，表示不能延續(xù)的動作，這種動作發(fā)生后立即結(jié)束。如 open,

24、 close, finish, begin, come, go, arrive, reach, get to, leave, move, borrow,buy 等。It rained at eight yesterday morning.（誤）rain 為延續(xù)性動詞，而at eight 表示"點(diǎn)時(shí)間"。上句可改為： It began to rain at eight yesterday morning.（正）I have borrowed the book for 2 mon ths.（誤）borrow是"借”不能做借這個(gè)動作做了2個(gè)月吧I have kept t

25、he book for 2months.（正）換成keep這個(gè)動詞，保持，借到手了就拿了2個(gè)月-Whe n did you get to know Jack? -Two years ago.-The n you've known each other for more tha n two years. -That's right.附加延遲動詞與瞬間動詞轉(zhuǎn)換表（部分）：注意be的作用很大瞬間動詞延續(xù)動詞瞬間動詞延續(xù)動詞put onwearendbe overbuyhavejoinbe inborrowkeepgo therebe therebecomebeget to/arriv
