I hope his health will have improves by the time you come back next year.这句话有没有问题?
will have improves 之前的一段话:在以if,as long as,as soon as,after,before,in case,until,unless等连词以及具有连词作用的副词(immediately,the moment,directly)等引导的状语从句,一般用现在时代替将来时.强调延续性或动态时,可用完成时.这个正确吗,到底是个什么时态?
will have improves形式错了
用将来完成时 will have improved (过去分词)
by the time you come back next year 这里用一般现在时表将来,正解!
by 要和完成时连用,主句指将来,当然用将来完成时 will have + 过去分词
