请教道难搞的SC

One report concludes that many schools do not have, or likely to have, enough computers to use them effectively.

(A) or

(B) nor

(C) or are

(D) nor are they

(E) nor are not

答案是D？WHY？

一定是nor

AC排除

E重复否定排除

B没有Be动词和主语

前面出现了not当然就要用nor了，但是likely的用法是be likely to do，所以be不能省略哦～

clear？

明白了，谢谢大家~~~

CDers的速度真快啊！
