题目内容：

Do you think we should accept that offer?-Yes,we should,for we ( )such bad luck up till now,and time( ) out.
A have had ; is running B had ;is running
C have; has been run D have had; has been run

优质解答

选A：根据up til now 这句话,我们可以断定这句话肯定得用完成时.所以我们可以排除B,C.我们再看AD选项,A的意思是"time is running out,及时间就快没有了" D选项的意思是"时间已经没有了" 很显然我们得选择A.
