     One of the best-known American writers is Samuel Clemens, whose pen name is Mark Twain. Born in

1835, Clemens grew up in the Mississippi River town of Hannibal, Missouri. As did many other young people

of his day, Clemens dreamed of traveling on riverboats and of someday becoming a riverboat pilot. He used

his memories (记忆) of the life of a river town in his two most famous books, Huckleberry Finn and Tom

Sawyer. 　　

     As a young man, Clemens held many jobs. He was a printer (印刷工), a gold miner (矿工) and a riverboat

pilot. During his pilot days, he used the name Mark Twain. This was a term used on the river to mean that

the water measured (测量) 2 fathoms (英寻), or 4 meters (nearly 12 feet), which was deep enough for safe

passage. 　　

     Finally Twain became a successful writer. He traveled a great deal, writing and speaking. He became very

popular both in the United States and in Europe. 　　

     Twain's style of writing was simple and direct. Among the things that he wrote about were superstitious

(迷信的) people and people who were really fool. He used his unusual gift for humor (幽默) to write about

many things of importance.
