单选题 Big Ben is not a name of a man. It is the name
of a big clock in London. London is the capital of England. This clock has four
faces. So, no matter where you stand, you can read the time on the face of Big
Ben. Each face is the size of a bus. The hands are about four meters long. It is
about the size of two people standing on top each other. If you go to London,
you may want to visit the House of Parliament. You will probably hear it and see
it. The big clock makes such a loud noise. "Dingdong, dingdong." It goes
every quarter of an hour. The name of Big Ben comes from a
great builder. This man did much building work in London many years ago.
