问题描述：
__the students is able to finish these exercises in time.
A not all B not every C nobody D not every one of
为何选D
答
A是部分否定，其谓语动词还必须用复数！B 有every 就不能有the，C就是明显错误了！小知识：everyone不能加of，every one可以加of，且谓语动词用单数！
答
因为is的前面是students啊，那么肯定就是one of sb（复数）is的，所以选D
答
a:如选A,则单复数不对,应用复数
b：every后面直接加名词,the多余
C：理由同B
D项正确
