I haven't seen

20、much of him recently (lately). We have seen that film before.

23、ster. 6.現(xiàn)在完成時的"完成用法" 現(xiàn)在完成時的"完成用法"指的是動作發(fā)生在過去某一時刻并已結(jié)束，但該動作對現(xiàn)在產(chǎn)生了影響，與現(xiàn)在情況具有因果關(guān)系。 例如：He has turned off the light.他已把燈關(guān)了。（動作結(jié)束于過去，但說明的是現(xiàn)在的情況-燈現(xiàn)在不亮了。） 現(xiàn)在完成時"完成用法"的特點是動作不延續(xù)，因此，該只能與表示不定的過去時間狀語（如：already，yet，before，recently等）、頻度時間狀語（如：never，ever，once等）、包括現(xiàn)在時刻在內(nèi)的時間狀語（如：this morni

24、ng / month /year.，today等）連用。 例如：Have you found your pen ？你已找到你的鋼筆了嗎？ 7.現(xiàn)在完成時的"未完成用法" 現(xiàn)在完成時的"未完成用法"指的是動作開始于過去某一時刻，一直延續(xù)到現(xiàn)在，或可能還要繼續(xù)下去。 例如：He has lived here since 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表示一段時間的（由since或for引導(dǎo)），或表示與現(xiàn)在時刻相連的時間狀語（如：up to now，so far）等。 例如：I have heard nothing from him up to now.到目前為止我沒有他的任何消息。 注意：（1）現(xiàn)在完成時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)時間很短的動詞。如：come，go，arrive，leave，join，become，die等。 8.一段時間+has passed+since從句 9. 現(xiàn)在完成時常和短語 "up to
