问题    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 pre- diet 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 ad- vice, 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.
The best title for the passage is______.
选项 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
答案A
解析 该题为主旨题。文中第一句给出气象学的定义：“The science of meteorology is concerned with the study of the structure，state，and behavior of the atmosphere．”接着第一段表明可从不同的角度来研究气象学。在下面段落中简单介绍了气象学的两大分支。因而A项，“对气象科学的探讨”，是文章大意。B项，“天气学的新进展”；C项，“气象预报的局性”；D项，“气象动力学的基本原理”，均不符合原文大意。
