Directions: There are 4 passages in this part. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C) and D). You should decide on the best choice and mark the corresponding letter on the Answer Sheet with a single line through the centre. Questions 1 to 5 are based on the following passage: The science of. meteorology is concerned with the study of the structure, state, and behavior of the atmosphere. The subject may be approached from several directions, but the scene cannot be fully approached from any one vantage point (有利的地位). Different views must be integrated to give perspective to the whole picture. One may consider the condition of the atmosphere at a given moment and attempt to predict changes from that condition over a period of a few hours to a few days ahead. This approach is covered by the branch of the science called synoptic meteorology（天气学）. Synoptic meteorology is the scientific basis of the technique of weather forecasting by means of the preparation and analysis of weather maps and aerological diagram （高空气象图）. The practical importance of the numerous applications of weather forecasting cannot be overestimated . In serving the needs of shipping, aviation, agriculture, industry, and many other interests and fields of human activity with accurate weather warnings and professional forecast advice, great benefits are obtained in the form of the saving of human life and property and in economic advantages of various kinds. One important purpose of the science of meteorology is constantly to strive, through advanced study and research, to increase our knowledge of the atmosphere with the aim of improving the accuracy of weather forecasts. The tools needed to advance our knowledge in this way are the disciplines of mathematics and physics applied to solve meteorological problems. The use of these tools forms that branch of the science called dynamic meteorology. 1.Which of the following statements best describes the organization of the third paragraph of the passage? A) A problem is examined and possible solutions are given. B) A procedure is explained and its importance is emphasized. C) Two contrasting views of a problem are presented. D) Recent scientific advancements are outlined in order of importance. 2. The author implies that increased accuracy in weather forecasting will lead to _______. A) a higher number of professional forecasters B) less-specialized forms of synoptic meteorology C) more funds given to meteorological research D) greater protection of human life 3.In the last sentence of the passage, the phrase "these tools" refer to ________. A) weather forecasts B) economic advantages C) mathematics and physics D) meteorological problems 4.The best title for the passage is _______. A) Approaches to the Science of Meteorology B) New Advances in Synoptic Meteorology C) The limitations of Meteorological Forecasting D) The Basics of Dynamic Meteorology 5.Which of the following is referred to by the author as a field whose needs are served by weather forecasting? A) Teaching. B) Transportation. C) Medical service D) Boxing.
