James has just arrived,but I didn't know he came until yesterday
正確答案是James has just arrived,but I didn't know he was coming until yesterday上面我寫的為什么不對(duì)為什么不能用came
回答：he came是他來了,昨天他還沒來呢,他要來而已
疑問：上面回答的意思是他昨天沒來,這個(gè)信息是從james has just arrived得來的嗎,
現(xiàn)在完成時(shí)不是表示過去發(fā)生并且已經(jīng)完成的動(dòng)作對(duì)現(xiàn)在造成影響或后果,所以我覺得也可說明JAMES昨天就來了,都是過去為何過去式came 不對(duì)而過去進(jìn)行was coming 對(duì)?
until這個(gè)時(shí)間狀語只能用在過去完成和現(xiàn)在完成,所以那個(gè)都不對(duì)吧應(yīng)該用had came是不是呢
