The speaker_______have arrived by now.What might have happened to him?应填应填was supposed to 还是 is supposed to
The speaker_______have arrived by now.What might have happened to him?应填
应填was supposed to 还是 is supposed to
The speaker_______have arrived by now.What might have happened to him?应填应填was supposed to 还是 is supposed to
正确形式是：
The speaker【is supposed to】have arrived by now.What might have happened to him?
=The speaker【should/ought to】have arrived by now.What might have happened to him?
=【We think 】the speaker 【should】 have arrived by now.What might have happened to him?
到现在为止,演讲者被认为应该到了.他出了什么事呢?
信息词：【by now】,表明时间是现在,即【到现在为止认为】.
祝你开心如意!
填was supposed to
The speaker was supposed to have arrived by now.What might have happened to him？

收起
我觉得是填is supposed to 第一句是说发言人本应该现在现在就到的（暗示现在还没到），但直至现在为止，他还是本应该现在就到的，所以不应该用过去式！希望帮到你哟！
The speaker _is supposed to_ have arrived by now.What might have happened to him？
发言人现在应该已经到了。他会发生什么事了呢？
应填现在时 is supposed to。因为句子里说，by now，现在应该到了。后面句子的 might have happened，不是过去时，是虚拟语气。
