题型:不详难度:来源:
---The president _____ by his doctor today that his cancer has come back.
A.informsB.has informed
C.has been informedD.is being informed

答案
C
解析

试题分析:考查时态。句意:总统今天被通知他的癌症又复发了。句意说明总统和通知之间构成被动关系,同时也表示已经被通知了故使用现在完成时的被动形式。故C正确。
点评:时态题的考查关键是抓住句子的上下文含义和句中的时间状语。要根据时间状语来选择合适的时态,在平时的学习中要注意积累有关时态的用法和各种时态的特殊之处。如since, so far等经常与现在完成时连用。在条件状语从句中用一般现在时代替将来时等等。
