有關(guān)by the time 的時(shí)態(tài)：
1.后接表示現(xiàn)在的時(shí)間,用現(xiàn)在完成時(shí).如 By the time of this term,we have learned 5000 words.
2.后接表示將來(lái)的時(shí)間,用一般將來(lái)時(shí)或?qū)?lái)完成時(shí).如 By the time 2012,we will learn 5000 words.(一般將來(lái)時(shí)) 或By the year 2012,we will have learned 5000 words.(將來(lái)完成時(shí))
3.后接表示過(guò)去的時(shí)間,用過(guò)去完成時(shí).如 I hadn’t found a job by the time my classmates all found their jobs.老師說(shuō)主句用一般現(xiàn)在時(shí)，從句用will have doneI am also a teacher of English.相信我！“老師說(shuō)主句用一般現(xiàn)在時(shí)，從句用will have done”此話嚴(yán)重錯(cuò)誤！
