People often like collecting things. Collecting stamps, books, pictures and pens are some common hobbies. I know many kinds of collections, but the strangest is a collection of clocks. My friend Mr. Clock, a short man, has the hobby. He has as many as one thousand five hundred clocks.
There are clocks everywhere in his house. You can see shelves are full of clocks. As there is not enough room for so many clocks, the man has to fill some boxes with clocks.
Although Mr. Clock likes his large collection of clocks, his wife does not enjoy them at all. She complains (埋怨) every day about the work she has to do, for it is not easy for her to clean hundreds of clocks. She also complains about the noise. Each clock keeps a different time. So she can hear the chimes (报点声) almost any time day and night. There is something even worse. With so many clocks around, she is never able to know what time it is!
