选择题
Can you think of some cases where drivers obviously______ the traffic rules but don’t obey them?
A．have instructed in
B．have instructed
C．have been instructed in
D．are instructed
答案
答案：C
题目分析：考查词组和语态：instruct sb.in sth.相当于teach sb.sth，instruct和drivers之间存在被动关系，故只能选择have been instructed in。句意：你能想到司机明显学习过交通规则但是不遵守的一些情况吗？选C。
点评：考查时态时别忘了考虑语态问题，考虑动词和主语的关系，避免出错。
