VII. 閱讀測驗 (20% 每題2分)    A.   Around the world, hand gestures can have different meanings. A familiar hand gesture in Taiwan can mean something quite different in Germany, the United States or even Hawaii. In Taiwan, if you are waving for a taxi, you reach out your hand with your palm (手心) facing down and move your hand up and down. This is a sign for the taxi to stop. However, if you were in another country and waved this way, the taxi might drive right past you because the driver would think you were waving goodbye.   Besides, just extending (伸出) one finger can cause confusion. Across most of the world, extending the index finger is the symbol for the number “one.” Yet, this is not true in Germany. When Germans count, they use their thumb as the number “one” and their index finger represents the number “two.” In addition, if a German visits the United States and gestures for a waitress to have another drink, he might extend his thumb. Unfortunately, he might get more than just one drink because the thumbs-up gesture in the United States means the person likes someone or something.   Nevertheless, even extending two fingers can have different meanings around the world. For example, in Taiwan the number six is represented by extending the thumb and the little finger. However, in Hawaii this is how they wave “hello.”Therefore, as you travel around the world, be careful of your hand gestures. You may be saying more than you mean to.
