单选题Ever since human beings have inhabited the earth, they have made use of various forms of communication. Generally, this expression of thoughts and feelings has been in the form of oral speech. When there is a language barrier, communication is accomplished through sign language in which motions stand for letters, words, and ideas. Tourists, the deaf, and the mute (哑巴) have had to resort to this form of expression. Many of these symbols of whole words are very picturesque(生动形象的) and exact and can be used internationally, spelling, however, cannot. Body language transmits ideas or thoughts by certain actions, either intentionally or unintentionally. A wink can be a way of flirting or indicating that the party is only joking. A nod signifies approval, while shaking the head indicates a negative reaction. Other forms of nonlinguistic language can be found in Braille (a system of raised dots read with the fingertips), signal flags, Morse code, and smoke signals. Road maps and picture signs also guide, warn, and instruct people. While verbalization is the most common form of language, other systems and techniques also express human thoughts and feelings.

单选题Some years ago the captain of a ship was very interested in medicine. He always took medical books to sea and liked to talk about different illnesses. One day a lazy sailor on his ship pretended to be ill. He lay on his bunk(铺) and groaned as if he were very sick. The captain came to see him and was very pleased to have a patient to look after. He told the man to rest for a few days and made the other sailors to do his work. Three days later another sailor pretended that he had something wrong with his chest. Once more the captain looked in his medical books and told the "sick" man to have a rest. The other sailors were very angry because they had more work to do. The patients had the best food and laughed at their friends when the captain was not looking. At last the mate(大副) decided to cure the "sick" men. He put some soap, glue and other unpleasant things together. Then he got permission from the captain to give his new medicine to the "sick" men. When they tasted the medicine, they really did feel ill. It was so horrible that one of the patients jumped out of his bunk, ran up on deck and climbed the highest mast on the ship. He did not want any more medicine. The mate told both of the men that they must take the medicine every half an hour, night and day. This soon cured them. They both said they felt better and wanted to start work again. The captain realized that the men had tried to deceive him so he made them work very hard for the rest of the voyage.
