you can't say "jump at QUANTITY". here, "to" is correct.
on the other hand, if the word "at" is part of some other construction, such as a time marker, then it could appear:
consumer spending always jumps at the end of the year, when the holiday season arrives.
here, "jump at" isn't really a construction; it's just "jump", followed by "at the end of the year".
1、整个句子的时间是in 1997，过去的时间，不能用现在完成时
2、the number jumped to 20%, jump to有跳起来以够到的意思，比jump at好

考点 动词形式
in 1997是过去时间标志词，动词时态用一般过去时，排除AC
jumped to...表示下降到.....jumped at表示下降了... 根据语义判断to 合理;排除DE
答案B
首先呢数据下降到了什么什么应该是To 而不是 at。 其次，在原文中的事情其实是发生了的，即便是在1997年看来，所以时态要用过去时。因此B比C好
We're looking IN RETROSPECT at a statistic from the full year 1997, summarizing what happened in that whole year. (We can rest assured that we're not sitting in December 1997, looking back at the year that's just passed us by, because of the talk about 'the sixth full year of uninterrupted expansion.) This means that we have to use the simple past tense ('has jumped' is inappropriate).
in 1997!
哦，明白了，看错了
不是应该先jump 再declare吗？jump包含declare时间段啊，应该选动词呀？
