单选题 One of the well-known of American writers is Samuel Clemens, whose pen name is Mark Twain. Bom in 1835, Twain grew up in the Mississippi River town of Hannibal, Missouri. As did many other boys of his day, Twain dreamed of traveling on river boats and of someday becoming a riverboat pilot. Twain used his memories of the life of a river town in his two most famous books, Huckleberry Finn and Torn Sawyer. As a young man, Twain held many jobs. He was a printer, a good miner, and, for a time, he was a riverboat pilot. During his pilot days, he adopted the name Mark Twain. This was a term used by the boatmen to mean that the water measured two fathoms, or twelve feet, which was deep enough for safe passage. Finally Twain became a successful writer. He traveled a great deal, writing and speaking, and became very popular both in the United States and in Europe. Twain's style of writing was simple and direct. Among the things he wrote about were superstitious (迷信的) people and people who were easily fooled. He used his unusual gift for humor to write about many things of importance.

单选题 The intelligence test used most often today are based on the work of a Frenchman, Alfred Binet. In 1905, Binet was asked by the French Ministry of Education to develop a way to identify those children in French schools who were too 'mentally deficient(不足的)' to benefit from ordinary schooling and who needed special education. The tests had to distinguish those who were merely behind in school from those who were actually mentally deficient. The items that Binet and his colleague Theophile Simon included on the test were chosen on the basis of their ideas about intelligence. Binet and Simon believed intelligence includes such abilities as understanding the meaning of words; solving problems, and making commonsense judgements. Two other important assumptions also shaped Binet's and Simon's work: (1) that children with more intelligence will do better in school and (2) that older children have a greater ability than younger children. Binet's first test consisted of thirty tasks. They were simple things most children learn as a result of their everyday experiences. The tasks were arranged in groups, according to age. Binet decided which tasks were appropriate for a given age group by giving them first to a large number of children of different ages. If more than half of the children, of a given age passed a test, it was considered appropriate for that age group.

单选题 Californian Michael Schwabe said goodbye to the gas pump two years ago. He leased an electric car. Schwabe says he gets more out of driving an electric car than just a charge. 'With the price of gasoline and with the problems with clean air, it’s important we get electric vehicles out on the road.' On California roads there are about two thousand electric cars. By 2003, ten percent of all new cars may be required to have zero emissions. This is a mandate automakers say it is way ahead of its time. Gloria Bergquist of the Alliance of Auto Manufacturers says, 'The technology (for zero emissions) isn’t here yet; it still needs advancement in driving range to make it more appealing to a wider consumer audience .' Automakers blame it on the batteries. Power runs out on most cars after about 70 miles. However, some cars can now go more than 100 miles on a charge. Batteries are expensive. Carmakers say there is nothing they can do about it. Tim Carmichael of the Clean Air Coalition says, 'The automakers have not built a vehicle unless required to do so, so it’s very important for the state to stay committed to this program requiring automakers to build small amounts in beginning years and then the market will take off.'
