书上说by the time 句子作时间状语句子一般过去,主要谓语动词过去完成时 ,看不懂,举两个例子吧 He left at ten.（by the time I got there作时间状语改写句子） He ____ ____ by the time I got there by the time加句子,句子中加时间状语,例如in 2000 ,可以吗 by the time of 2015,有这个时间状语的句子主句用什么时态? He climbs the mountains once a week.(用this time yesteday作时间状语改写句子) During the time that he was away,she was sad.书上的句子,但我觉得应该用when代替that,我觉得应该用关副而不是关代，时间概念作副词呀 不及物动词的过去分词短语可以作后置定语吗?书上说作后置定语的过去分词都是及物动词 但 像下面一个句子成立吗?The beautiful landscape stared at by us is painted by a sixteen-year-old boy.我觉得 不及物 随着时间的流逝 as the time goes by （went by ）都有,那有没有用进行时态的呢能不能说as the time is going by. by the time ,by then By the time by the time 将来完成时+by the time+一般现在是 结构 造个句子!还有过去完成时+by the Time+一般过去式, 我的旧老师说1.by the end of+过去时间,句子用过去完成时2.by the end of+现在时间,句子用现在完成时3.by the end of+将来时间,句子用一般将来时代替将来完成时我的新老师说第3条不对,就用将来完成 用英语造句,不要太简单,each time+句子 （作时间状语）the next/first timeevery timethe moments / as soon as 句子The time fairly raced by.最后的by有什么意义? we,reached,the,the,top,by,time,had,the,the,sun,mountain,of,risen,组句子 改写这个句子 I told you he would receive the parcel in time.用the parcel作主语这是我改写的：I told you that the parcel would be received in time by him.或 The parcel would be received in time by him as i told you.我看网上有另 by the time是点时间,还是段时间,所以用一般过去,还是完成时态
