現(xiàn)在完成時(shí)與一般過去時(shí)的區(qū)別
一般過去時(shí)表示的動(dòng)作或狀態(tài)，可以是一次性的，也可以是經(jīng)常性的，所表示的動(dòng)作或狀態(tài)與現(xiàn)在無關(guān)�，F(xiàn)在完成時(shí)表示的動(dòng)作或狀態(tài)與現(xiàn)在情況有聯(lián)系，側(cè)重這一動(dòng)作對(duì)現(xiàn)在所造成的影響。如：
I had supper an hour ago．
我一小時(shí)前吃的晚飯。（表示過去的動(dòng)作）
I have just had supper．
我剛剛吃過晚飯。（強(qiáng)調(diào)對(duì)現(xiàn)在的影響---我不餓）
區(qū)分現(xiàn)在完成時(shí)（has/have done）與現(xiàn)在完成進(jìn)行時(shí)（has/have been doing）
現(xiàn)在完成時(shí)有否定結(jié)構(gòu)，現(xiàn)在完成進(jìn)行時(shí)沒有否定結(jié)構(gòu)。
現(xiàn)在完成時(shí)可表示做完的時(shí)期以及已有的經(jīng)驗(yàn)，但現(xiàn)在完成進(jìn)行時(shí)不可以。
現(xiàn)在完成時(shí)強(qiáng)調(diào)對(duì)現(xiàn)在的影響�，F(xiàn)在完成進(jìn)行時(shí)強(qiáng)調(diào)過去那一段過程（對(duì)現(xiàn)在的影響）。
