1,be动词包括am,is,are,你肯定知道you are...这个句子,所以反义是aren't
2,might和must一样,你只用看人称he。just now 表示刚才,属于过去。本身应该是isn't he就变成了wasn't he.
3,昨天一定下雨了,简化句子it rained yesterday。所以反义是didn't.
解答完毕。
首先找出反问内容,然后看原句中是否有be动词,助动词等以及时态,没有就看单词的词性应用什么来反问。还有个口诀:前否后肯,前肯后否。
I have to go now, don't I?
当句中没有出现IS,ARE时,应为句中的动词为have,所以就用助动词do来进行提问。
You must be joking now, aren't you?
He might be sleeping just now, wasn't he?
这两句中的动词都是be,英雌根据人称和时态,用不同的be动词。
It must have rained yesterday, didn't it?
这句的道理跟第一句一样,只不过是时态改变。
I like you . so do I.
you are so cute ! so you are.
当两人说的是同一个主语的时候,就不用倒装。若是不同诸于世,需要倒装。还有,要注意时态的一致和动词的一致
I have to (go) now, don't I?为什么是DON'T?
You must (be) joking now, aren't you?为什么是AREN'T?
He might (be) sleeping just now, wasn't he?没有WAS出现呀?
It must (have rained) (yesterday), didn't it?为什么是DIDN'T
这些带助动词的,都要跟从它的原始动词,用括号里表示了。
I LIKE YOU, 回答应该是, so do I
YOU ARE SO CUTE,是SO ARE YOU
