—Good afternoon, Davison's Plumbing. Can I help you?
—I'd like a plumber to take a look at my toilet, please. It seems to be blocked.
—Certainly. ________. Wait a moment...Well, you're in luck. His last appointment was called off, so he can fit you in at about 5o'clock.

A、 And the plumber will sort out the cause of the problem.
B、 But the plumber is completely tied up with appointments all day.
C、 And the plumber will go ahead with the work.
D、 But the plumber may not be able to make it there until this noon.

【正确答案】 B

【答案解析】

在本题中，根据对话的内容可知 “ 主人公因为厕所堵住需要请一名水管工进行修理 ” ，并且根据服务人员的回答可知“ 主人公非常幸运，水管工最后一个预约被取消，因此可以按时修理 ” ，由此可知与 B 项中 “tied up with appointments all day”相呼应，因此 B 项符合题意。
