Do you know about Big Ben? Now let me tell you about it.
Big Ben is not the name of a man. It is the name of a huge clock in London. London is the capital of the UK. This clock has four faces, so no matter (无论) where you stand, you can read the time on the face of Big Ben. Each face is the size of a double-decker(双层的) bus. The hands are about four metres long. It is about the size of two people standing on top of each other. If you go to London, you may want to visit the House of Parliament(国会大厦). That is where you will find Big Ben sitting at the top of the clock tower(塔) in the House of Parliament. You will hear it as well as see it. The big clock makes such a loud sound, "Ding Dong, Ding Dong," when it goes every quarter(四分之一) of an hour. The clock was named after a big man. He was Sir Benjamin Hill. He did much building work in London many years ago.
