题目内容

[　　]

A．when
B．before
C．since
D．while
答案：C
解析：

　　思路分析：该题考查根据语境选择适当的从属连词．四个选项的从属连词都能引导时间状语从句，但since表示“自从……以来”，后接从句时应与主句的时态呼应．主句用现在完成时，since引导的从句用一般过去时．例如：

　　How have you been since we parted?

　　分手以来，你还好吗？

　　They've moved house twice since they got married.

　　他们婚后已搬过两次家．

A jobless man wanted very much to have the position of “office boy” at Microsoft. The HR manager interviewed him and then watched him cleaning the floor as a test. “You have passed the test,” he said. “Give me your e-mail address and I’ll send you the form to fill in and the date when you may start.” The man replied, “But I don’t have a computer, neither an e-mail.” “I’m sorry,” said the HR manager. “If you don’t have an e-mail, that means you are not living. And anyone who isn’t living cannot have the job.”

The man left with no hope at all. He didn’t know what to do with only $10 in his pocket. He thought and thought. Then he went to the supermarket and bought 10 kilos of tomatoes.

Shortly, he bought a cart , then a truck, then he had his own fleet of delivery vehicles(运货车队). Five years later, the man was one of the biggest food retailers (零售商)  in the US.
