Ⅰ.单项填空
从A、B、C、D四个选项中选出可以填入空白处的最佳选项。
1．He________more than 5,000 English words when he entered the university at the age of 15.
A．has learned B．would have learned
C．learned D．had learned
【解析】 考查动词时态的运用。根据句子中的时间状语when he entered the university at the age of 15可知，在上大学之前学的英语单词，故用过去完成时。
【答案】 D
2．—I met Tom last month.
—Really?
—Yes.We________each other since we graduated from college.
A．haven’t met B．hadn’t met
C．wouldn’t meet D．didn’t meet
【解析】 句意是指从大学毕业到上个月，我们是第一次见面，所以用过去完成时态。
【答案】 B
3．—Mike，who is now lying in hospital，says how he wishes he hadn’t got drunk.
—Yes，no one knows the value of health________he has lost it.
A．until B．when
C．after D．since
【解析】 考查连词用法。no one表示否定含义，与until连用表示“直到……才……”，此句意思是“直到失去健康后人们才知道它的重要”。B、C两项在意义上干扰性很强，但与no搭配不合理。
【答案】 A
4．The global price of oil________from $147 per barrel to $40 per barrel during the last ten months.
A．has fallen B．will fall
