Q：What did the woman want to do?

Most people always like buying things,　 for example,　 stamps,　 clothes,　 books,　 pictures and so on. But my friend Mr. Brown likes buying clocks. He has three hundred clocks now.

There are clocks everywhere in his house. You can see shelves stand in every room. All the shelves are full of clocks.

Mr. Brown likes to do it very much, but his wife doesn't enjoy it at all. She has to clean each clock every day,　 and it’s very difficult to do so. She is also angry at the noise. Each clock keeps its own time. So she can hear the sound of the clocks almost anytime during the day and night.

She says, "The trouble is that I never know the real time,　 though I have so many clocks around. "
