问题补充：

The students were all tired but of them stopped .

A. no, to rest

B. none, to rest

C. no, resting

D. none, resting

答案：

A. no, to rest

(答案→)B. none, to rest

C. no, resting

D. none, resting

解析：句意：学生们都累了，但是没有一个人停下休息。none表示“没有一个人或物”，与of 连用；no表示否定意义，后常接名词。stop to do sth ：表示停止正在做的事而去做另一事，stop doing sth ；表示停止正在做的事。结合语境可知，没有学生停止正在做的事而去休息。故选B。
