D. stick to

A. keep onB. keep to(答案→)C. stick outD. stick to解析：　stick out(=keep on doing sth。until it is done，no matter how long，hard，or unpleasant) 坚持下去: Mathematics is hard，but if you stick it out you will understanding it(=Mathematics is hard，but if you keep on working hard at it you will learn it.) 此外，stick on 还可表示 (stand out) 突出: The skyscraper sticks out against the bkue sky.(这幢摩天大楼映着蓝图显得格外突出.)　　[注意] stick out与keep to 均有“坚持”的含义。stick out 特指“坚持下功夫干一件事，不完成决不收兵”；而keep to 则强调“坚持、遵守、坚守”诺言、规则、原则、精神、岗位。可见，keep to 的英文释义为 ability by；adhere to，stick closely to。例如: keep to one's promise(遵守诺言)；keep to the rules of a game(遵守比赛规则)；keep to a principle(坚持原则)；keep one's pos(坚守岗位)。因此，我们可以说keep to相当于 stick to，而区别于 stick out.
