正确答案:

正槽溢洪道和侧槽溢洪道的不同之处在于侧槽溢洪道的水流过堰后,在侧槽内转90°,大部分能量消耗在侧槽内的水体旋滚,再经泄水槽泄入下游。侧槽内水流紊乱,撞击很剧烈;而正槽溢洪道则水流顺畅,水力条件好。

Part I Reading Comprehension Directions: In this part there are four passages. Each passage is followed by four comprehension questions. Read the passage and answer the questions. Then mark your answer on the Answer Sheet. Passage 1 Questions 1 to 5 are based on the following passage: Ask three people to look the same window at a busy street corner and tell you what they see. Chances are you will receive three different answers. Each person sees the same scene, but each perceives something different about it. Perceiving goes on in our minds. Of the three people who look out the window, one may say that he sees a policeman giving a motorist a ticket. Another may say that he sees a rush-hour traffic jam at the intersection. The third may tell you that he sees a woman trying to cross the street with four children in tow. For perception is the mind’s interpretation of what the senses—in this case our eyes—tell us. Many psychologists today are working to try to determine just how a person experiences or perceives the world around him. Using a scientific approach, these psychologists set up experiments in which they can control all of the factors. By measuring and charting the results of many experiments, they are trying to find out what makes different people perceive totally different things about the same scene. 1. Seeing and perceiving are . A. the same action B. two separate actions C. two actions carried on entirely by eyes D. several actions that take place at different times 2. Perceiving is an action that takes place . A. in our eyes B. only when we think very hard about something C. only under the direction of a psychologist D. in every person’s mind 3. People perceive different things about the same scene because . A. they see different things B. some have better eyesight C. they cannot agree about things D. none of these 4. Which of the following is implied but not stated in the passage? A. Psychologists do not yet know people see. B. The experiments in which all factors are controlled are better. C. The study of perception is going on now. D. Perception does not involve psychological factors. 5. The best title for this selection is . A. How We See B. Learning about Our Minds through Science C. What Psychologists Perceive D. How to Because an Experimental Psychologist
