单选题{{B}}Passage 3{{/B}} Einstein, Albert (1879--1955), German-born American physicist and Nobel winner, best known as the creator of the special and general theories of relativity and for his bold hypothesis concerning the particle nature of light. He is perhaps the most well-known scientist of the 20th century. Einstein was born in Ulm on March 14, 1879, and spent his youth in Munich, where his family owned a small shop that manufactured electric machinery. He did not talk until the age of three, but even as a youth he showed a brilliant curiosity about nature and an ability to understand difficult mathematical concepts. At the age of 12 he taught himself geometry. Einstein hated the dull rules and unimaginative spirit of school in Munich. When repeated business failure led the family to leave Germany for Milan, Italy, Einstein, who was then 15 years old, used the opportunity to withdraw from the school. He spent a year with his parents in Milan, and when it became clear that he would have to make his own way in the world, he finished secondary school in Arrau, Switzerland, and entered the Swiss National Polytechnic in Zurich. Einstein did not enjoy the methods of instruction there. He often cut classes and used the time to study physics on his own or to play his beloved violin. He passed his examinations and graduated in 1900 by studying the notes of a classmate. His professors did not think highly of him and would not recommend him for a university position. For two years Einstein worked as a tutor and substitute teacher. In 1902 he secured a position as an examiner in the Swiss patent office in Bern. In 1903 he married Mileva Marie, who had been his classmate at the polytechnic. They had two sons but eventually divorced. Einstein later remarried.

单选题All of us communicate with one another verbally (口头的) as well as non-verbally. Most of the time we are not aware that we're doing it. We wave a hand, meet someone else's eyes or look away, shift positions in a chair. We make these movements unconsciously. But researchers have discovered that there is a system to them almost as consistent (一致的) and comprehensible as language. Every culture has its body language. The way an Englishman crosses his legs is nothing like the way a male American does it. In talking, Americans are likely to end a statement with a lowering of the eyelids. They conclude a question with a lift of the hand or a widening of the eyes. With a future-tense verb they often gesture with a forward movement. There are regional idioms too. Your sex, ethnic background, social class and personal style all influence your body language. Nevertheless, you move and gesture within a certain idiom. Usually, the wordless communication acts to qualify the words. What the non-verbal elements express very often, and very efficiently, is the emotional side of the message. When a person feels liked or disliked, often it's a case of "not what he said but the way he said it." Experts in the study of communication through body movement are not prepared to spell out a precise vocabulary of gestures. When an American rubs his nose, it may mean he is disagreeing with someone or rejecting something. But there are other possible interpretations, too. The expert looks for patterns in the context, not for an isolated meaningful gesture.
