by the time 1)到…時(shí)候?yàn)橹? 2)…當(dāng)……的時(shí)候;
by the time 1)到…時(shí)候?yàn)橹?br/>通常引導(dǎo)一個(gè)時(shí)間狀語(yǔ)從句,表示“到……的時(shí)候?yàn)橹埂敝骶鋭t表示在此時(shí)間之前某個(gè)事件已完成.值得注意的是,當(dāng)從句用過(guò)去時(shí)時(shí),主句通常用過(guò)去完成時(shí).
例如：By the time l got to the station,the train had
already gone.
2)…當(dāng)……的時(shí)候
如果只是說(shuō)過(guò)去某個(gè)時(shí)候的狀況,用過(guò)去時(shí),而不用完成時(shí).你的這句就是如此.By the time the war was over ,death and suffering were to be seen everywhere.在戰(zhàn)爭(zhēng)結(jié)束的時(shí)候,到處可見(jiàn)死亡和饑餓.這里沒(méi)有“死亡和饑餓”已經(jīng)完成的意思,只是描述當(dāng)時(shí)這個(gè)時(shí)間點(diǎn)的狀況.所以用過(guò)去時(shí).
