Within the last year，scientists have come closer than ever ______ ． A）to deciding which of the questions is right B）to decide which of the questions is right C）deciding whether the question is right or not D）and decided which of the questions is right 去年，科学家们比以往更能进一步确定哪些问题是对的。 come closer to:更靠近，接近。。。to在这里是介词，那我们就选A吧。 因为这句话有比较的意思，closer，那我们肯定是去年跟之前比较，所以这里用了than ever，后面比较的结构有承前省略了。 不知道这样解释会不会合理。 |
| Seems choosing A is right. |
