筒子,因?yàn)榍懊嬉痪湔f了是昨天見著我的同學(xué)的,就是說在昨天之前我已經(jīng)沒看見她好幾年了,沒見著的動(dòng)作是發(fā)生在在遇見之前,所以是過去的過去,所以說用過去完成時(shí).選B.
現(xiàn)在完成是從過去發(fā)生的動(dòng)作持續(xù)到現(xiàn)在,對(duì)現(xiàn)在有影響,比如說I have had an apple.(所以現(xiàn)在不餓）.而過去式I had an apple.就是過去發(fā)生的動(dòng)作,與現(xiàn)在無關(guān)了.
過去完成時(shí)是用來表示發(fā)生在過去的過去的動(dòng)作.比如說昨天在看比賽之前我吃了一個(gè)蘋果：I had had an apple before the match started yesterday.
希望能對(duì)你有點(diǎn)幫助!
