Answer 1

【答案】D

【解析】

句意：--济南曾经很小又很脏。 --我同意。但是自从全运会以来发生了巨大的变化。

A. is used to表示习惯做某事，后加doing，B. is used for被用来做某事，后加doing，C. is used by被什么使用，后加doing，D. used to过去常常，后加动词原形。根据But great changes have taken place since the National Games was held，可知济南发生了很大的变化，前面应该说的是过去怎么样，used to do sth过去常常做某事或怎么样，故选D。
