A proposal has been made to trim the horns from rhinoceroses to discourage poachers; the question is whether tourists will continue to visit game parks and see rhinoceroses after their horns are trimmed. (A) whether tourists will continue to visit game parks and see rhinoceroses after their horns are (B) whether tourists will continue to visit game parks to see one once their horns are (C) whether tourists will continue to visit game parks to see rhinoceroses once the animals' horns have been (D) if tourists will continue to visit game parks and see rhinoceroses once the animals' horns are (E) if tourists will continue to visit game parks to see one after the animals' horns have been
答案选C,我倒是选对了。但是看到OG的解释,说C对的原因之一就是因为“once the animals' horns have been”这个句子的时态用得对。那我就不懂了。如果主句用的是将来时will,像OG说的为了保证逻辑一致,从句只要用将来时之前的时态都可以啊。为什么一定要用完成时,一般时不行么?
不好意思,时态方面是完全晕。每次都只能尽量找其他方面的问题。那问高手能系统给讲一下最好不过了。感谢感谢:)
另一个小问题,OG说这里一定要用visit...to see。我怎么脑子就转不过来呢,觉得用and和to都无所谓呀?
