表猜测可以用there could be...很奇怪,练习中说there might be对,there could be不对. can和could都可以表虚拟和猜测么? can be,could be的用法求教can be和could be的用法,其间是否有联系?另外,除must be, can't be 和这两个之外,还有什么可以表猜测的词 might、may,could和must 表猜测的区别? must might could can't表猜测的用法 Could be there anything different?这句话有错吗?是应该是 Could be there,还是 Could there be you could be onto something there. i parked my car right under the big tree ,but now it's gonge .where it be?i parked my car right under the big tree ,but now it's gonge .where could it be?为什么用could不用may不是may 和can‘t表猜测嘛？ 用will there be 提问的可以省略be吗?还有there be的句型中不能省略there be The road conditions there turned out to be very good,which was more than we could expect为什么要加there?The road conditions turned out to be very good,which was more than we could expect 不可以么? 请问it的问题 Could you know where my books are Did you check the cabinet.( ) should be there.请问they 也可以代表物品吗?可以用its吗? what a beautiful place!I wish I could be there now.是虚拟语气吗?如果是虚拟语气为什么用could be ,对现在的的虚拟不应该用过去是吗?我是说COULD BE 改成WERE 行不行 could be very dangerous when there is a there could be more than one possible answer翻译 there could be l___of clouds in the sky there be no doubt that为什么可以用there be 句型 Could it be that there is a twin spirit out there for each of usCould it be 最主要的是：用了什么语法,怎么用的 情态动词表猜测这几个情态动词,在表猜测时有何区别（包括否定形式）?may can might could
