Customers are asked to make sure that they ____ the right change before leaving

题型:不详难度:来源:

Customers are asked to make sure that they ____ the right change before leaving the shop.
A.will giveB.have been givenC.have givenD.will be given

答案
B
解析

试题分析:考查时态,由后面的句子before leaving the shop.可以知道动作已经完成,所以用完成时,they和动词give是动宾关系,所以用被动式,句子意思“消费者被要求离开商店之前做出正确改变”, make sure固定词组“确保”,后面跟从句,所以选B
点评:做时态题时,首先看时间状语,由时间状语来确定句子的时态;如果没有时间状语,可以根据隐含的意思来确定句子时态。
