延續(xù)性動詞與非延續(xù)性動詞
1.現(xiàn)在完成時的“未完成用法”。
現(xiàn)在完成時表示動作或狀態(tài)從過去某時開始，一直延續(xù)至今，還可能繼續(xù)下去。這種用法稱為“未完成用法”。此時常與 fr 或 since 引導的時間狀語(從句)連用。
“未完成”的句式：（1）現(xiàn)在完成時+ fr +一段時間 例：我好久沒有見到她了。 I haven’t seen her fr a lng time.（2）現(xiàn)在完成時+ since +表示過去的時間點 例：自1984年以來，史密斯先生就在這里工作。 Mr. Smith has wrked here since 1984.
（3）現(xiàn)在完成時+since+從句 例：自上大學以來他學了大約5000個英語單詞。 He has learned abut 5000 English wrds since he went t cllege.
謂語動詞用延續(xù)性動詞，可以用hw lng提問。
2.延續(xù)性動詞與非延續(xù)性動詞
(1)延續(xù)性動詞表示經(jīng)驗、經(jīng)歷； 非延續(xù)性動詞表示行為的結(jié)果。 非延續(xù)動詞不能與表示一段時間的狀語連用。有些非延續(xù)性動詞可以用延續(xù)性動詞替換并用在現(xiàn)在完成時中。
