含有seem的问题

Now no product seems ______ able to occupy the market.

A. have been B. to be C. to have been D. being

答案是B。请教老师，是不是可选C？B 表示好像将要占领市场， C表示好像已经占据了市场。

所以，C是不是也正确呢? 谢谢老师。

Now no product seems ______ able to occupy the market.

A. have been B. to be C. to have been D. being

网友理解正确，是这么个理。不过，句子描述的是目前和以后的状况 ，不是过去。假如修饰不定式的是过去时间，则可以说：

No product seemsto have beenable to occupy the market in the past few years.
