过去将来是否定形式

1. isn't/aren't+过去分词 2.won't +be+过去分词 3.wouldn't +be+过去分词

过去将来时否定形式被动语态的谓语部分的构成主要有: 一、would/should not be +动词的过去分词.例如:1. He said he wouldn't be blamed if he finished his homework.他说如果他完成了作业就不会被责罚.2. I asked my mother whether I

过去将来完成时用法: 1、 过去将来完成时表示在过去将来某一时间以前发生的动作,并往往会对过去将来某一时间产生影响. 2、 过去将来完成时还常用在虚拟语气中,表示与过去的事实相反. 构造:should / would have done sth 疑问句: Would John have gone home without his briefcase? Yes, he would. No, he wouldn't.

Would you do.?肯定回答Yes,I would.否定回答No,I wouldn't.Would sb. do.?肯定回答Yes,sb. would.否定回答No,sb. wouldn't.你只要按这个套就可以了

一、用法 过去将来时表示从过去某个时间看将要发生的事情. 二、构成 过去将来时由would, was/were going to, was/were to was/were about to等加动词原形构成, 也可由was/were on the point of加动名词构成. I knew you would agree. 我知道你

过去将来时: 1.概念:立足于过去某一时刻,从过去看将来,常用于宾语从句中. 2.时间状语:the next day(morning, year…),the following month(week…),etc. 3.基本结构:was/were/going to + do;would/should + do. 4.否定形式:was/were/not +

举个例子: 疑问句:was he killed? 否定句:he was not killed. 肯定句:he was killed. 因为被动语态一定用上动词 to be,所以句子在形态上和用名词或形容词作表语的句子一样.

过去进行时

现在进行时的否定形式,是直接在be 的后面加个not.例子:肯定式:be(am/is/are) doing sth.否定式:be(am/is/are) not doing sth.如:i'm watching tv.--- i'm not watching tv.he is doing his homework.---he is not/isn't doing his homework.they are reading english.---they are not / aren't reading english.

形式 表示从过去某一时间开始一直延续到过去将来某一时间,过去将来完成进行时是由should/would have been + v-ing构成;否定形式should/would+not have been + v-ing;疑问形式是将should/would提前.
