Question

In the chemistry class, the students ________ into five groups to do the experiments.

A.divided B.were divided C.were dividing D.would divide

Answer

B

【解析】

句意：在化学课上，学生被分成五组做实验。

考查一般过去时、被动语态。divided一般过去时、主动语态； were divided一般过去时、被动语态；were dividing过去进行时；would divide过去将来时；从文字的表层意思可知，主语the students与动词divide之间是被动关系，判断空格用被动语态，故选B。
