如题，un-和not ...有区别吗？那个更好呢？
63. (27740-!-item-!-188;#058&003625) D B

Compared to those who do not, running three days a week saves an average of 14.1 percent on health-care costs each year in the United States.

(A) Compared to those who do not, running three days a week saves
(B) Compared with nonrunners, people who run three days a week save
(C) Compared to not running, those running for three days a week save
(D) When compared with those who do not, people running three days a week save
(E) When compared to nonrunners, running three days a week saves

觉得B的nonrunner 用的不好；D中的do 不可以指代run 吗？running 是动词性啊~
谢谢NN们！！

D中的running不是动词性，而是形容词性。do必须对应动词原形。
