8．The students how to do the experiment in class yesterday．（ ）| A． | were taught | B． | taught | C． | was taught | D． | teach |
分析 昨天在课堂上教学生们如何做实验．
解答 答案：A 根据The studentshow to do the experiment in class yesterday句中时间状语为yesterday可知是一般过去时态，根据主语the students是谓语动词
teach的承受者，二者是被动关系，故用被动语态，所以该空用一般过去时被动语态，一般过去时被动语态的结构为was/were+及物动词的过去分词，又知主语the students是复数，动词be用were，故选A
点评 要根据时间状语来确定时态，根据主语是动作的承受者，来确定是被动语态
