一般過(guò)去時(shí)指過(guò)去發(fā)生的動(dòng)作或存在的狀態(tài)；
而現(xiàn)在完成時(shí)強(qiáng)調(diào)過(guò)去的事件對(duì)現(xiàn)在造成的影響；
過(guò)去完成時(shí)是過(guò)去的過(guò)去,一般句中有過(guò)去式做參照,且該動(dòng)作在這個(gè)一般過(guò)去式之前發(fā)生；
現(xiàn)在完成進(jìn)行時(shí)是指過(guò)去的動(dòng)作到目前仍沒(méi)有結(jié)束還有可能繼續(xù)下去；或剛剛結(jié)束,但對(duì)現(xiàn)在又影響.可以有例句么？一般過(guò)去時(shí):eg:the tape recorder was out of order last week. we had it repaired the day before yesterday. it has been in good condition ever since.現(xiàn)在完成時(shí)my friend Mary said that he would come to my birthday party tonight, but he hasn't come so far. 現(xiàn)在完成進(jìn)行時(shí)i haven't seen Diana these days; i am afraid she hasn't been feeling herself.i have been reading the book these days and i can finish reading it within two days
