选择题
—Nice to see you again after all these years. What _____?
—Well, I’ve tried many things since we left school. I’m now working for a large oil company.
A．have you done
B．were you doing
C．did you do
D．have you been doing
答案
答案：D
题目分析：考查时态。句意：—这么多年以后再次看见你真是太好了。这些年你一直在做什么？—自从我毕业以后我尝试了很多事情。我现在一家大型的石油公司。根据句意说明是问对方这些年在做什么，故使用现在完成时表示。D正确。
点评：时态的考查要根据上下文的语义和句子的关键词。本题的关键词的all these years.
