By the time you have finished this book,your meal will get cold.bythetime的主句不应该用完成时吗?
知道里面这个问题有很多解释,都不能说服我,

By the time you have finished this book,your meal will get cold.bythetime的主句不应该用完成时吗?知道里面这个问题有很多解释,都不能说服我,
by the time引导的时间状语从句是根据时态不同改变的哦,所以不要看到这个标志就理所当然地认为要用完成时.确实,如果by the time后面接着的从句用了过去时,主句就要用过去完成时.但是整个句子表示的是将来的事情,就要根据主将从现（这点跟when引导的时间状语从句在将来时的用法一样可类比）
PS:by the time也有当..的时候的意思,表示这个意思时用法就与when一致了~
所以理解句意是很重要的~

by the time引导的时间状语从句应当用一般现在时。
英语语法中有个原则，叫做主将从现，即主句为一般将来时的时候，从句应当用一般现在时表示将来。
所以，本句应为：
By the time you finish this book,your meal will get cold.
供参考。
