求助：一道外语题，并希给详细解释，How can I make my feet ( ),Doctor Li ? 答案 don't smell

How can i make my feet don't smell, Doctor Li?~~~~~~~~~~~总感觉比较怪，因为 make sth/sb do..., 应该how can i make my feet not smell就可以了。
如果非要按原答案来，我觉得可以有两个解释：
1.句子省略了一个that,应该是how can i make (that)my feet don't smell, Doctor Li? that后面的丛句里必须要有don't.
2.用do表强调，例如 i believe in him.(我信任他。) i do believe in him.(我的确/真的信任他。)这么用的do若放否定句中最好不要缩写~ 原句就变成了：How can i make my feet do not smell?(我到底如何才能...)表示强调~
