[高考示例]

A. is used B. are used C. has been used D. have been used
[答案] A
[解析] 根据第二个句子的时态可以判断出第一句应该用一般现在时。
[拓展] 考查人称、时态等用法是考试中出现的最多的题目,因此,根据上下文来判断人称、时态就显得非常重要。再如:
When Mark opened the door, he saw a woman standing there . He __________ her before.
A. never saw B. had never seen C. never seen D. has never seen
此题的答案为B。选择过去完成时就是因为第一句的动作是过去的,而空格的动作在第一句的动作之前发生。所以要尤其注意上下文的提示。
