I really wonder__________ he has posted

问题选择题

I really wonder__________ he has posted me many parcels___________ we didn’t work together.

A．that; before

B．which; since

C．X; when

D．that; since

答案

答案：D

英语中的连词since有这样的特性：终止其后从句中的延续性的谓语动词的动作。第二个空白处填人since之后，这个从句的意思是：自从我们不在一起工作起。此外，since还可使其后从句里的非延续性的谓语的动作延续。例如：It is 15 years since he joined the Army．(他参军已经十五年了。)
