知識點(diǎn)一現(xiàn)在完成時(shí)

一般過去時(shí)與現(xiàn)在完成時(shí)的區(qū)別：

(1) 一般過去時(shí)表示過去某個(gè)時(shí)間發(fā)生的事、存在的狀態(tài)或經(jīng)常發(fā)生的動(dòng)作。說話的側(cè)重點(diǎn)只在 于陳述一件過去的事情，不強(qiáng)調(diào)對“現(xiàn)在”產(chǎn)生的影響。

(2) 現(xiàn)在完成時(shí)表示動(dòng)作發(fā)生在過去，對現(xiàn)在造成了影響或產(chǎn)生了結(jié)果。不與確定的過去時(shí)間狀 語連用。

(3) 兩種時(shí)態(tài)的區(qū)分：

① 一般過去時(shí)的謂語動(dòng)詞用過去式，而現(xiàn)在完成時(shí)的謂語基本構(gòu)成是“助動(dòng)詞have/has+過 去分詞”。如：The film started at 7 o’clock. He has been a teacher for many years.

② 一般過去時(shí)通常與表示過去的時(shí)間狀語連用，如：yesterday,last week,two years ago,just now,in 2002 等；而現(xiàn)在完成時(shí)則常與 j ust,already,ever,never 等副詞和 these days,this week,since..•，for…等表示一段時(shí)間的狀語連用。
