17.        (25335-!-item-!-188;#058&002335)

The success of the program to eradicate smallpox has stimulated experts to pursue what they had not previously considered possible--better control, if not eradication, of the other infections such as measles and yaws.

(A) what they had not previously considered possible--better control, if not eradication, of the other infections such as

(B) what they had not previously considered a possibility--better control, if not eradication, of such infections like

(C) something they had not previously considered possible-better control, if not eradication, of such infections as

(D) something not considered a previous possibility--better control and perhaps eradication, of other infections such as

(E) the possibility of what they had not previously considered--better control and possibly eradication of infections like

这里的小横杆为什么有时是一个，有时是2个，有区别吗？

C中的possible-better是一个词吗？B中的possibility-better呢？E中的consider后边的小横杠又代表什么呢？

lz 有没有仔细看过OG啊

小横杆，嘿嘿，太可爱了

是破折号嘛，

如果在句中的话，当然要两个破折号啊，类似逗号，把插入语和主句分开

如果在句末，当然只需要一个破折号拉

用 something代替名词性从句what ，简洁
