2014 高考英语阅读理解基础训练二轮精品题（5）及答案 <br />阅读理解 B <br />A weather map is an important tool for geographers. A succession of three or <br />four maps presents continuous picture of weather changes. Weather forecasters are <br />able to determine the speed of air masses and fronts (气锋) to determine whether <br />an individual pressure area is deepening or becoming shallow and whether a front <br />is increasing or decreasing in intensity (强烈). They are also able to determine <br />whether an air mass is retaining its original characteristics or taking on those <br />of the surface over which it is moving. Thus, a most significant function of the <br />map is to reveal a summary picture of conditions in the atmosphere at a given time. <br />All students of geography should be able to interpret a weather map accurately. <br />Weather maps contain an enormous amount of information about weather conditions <br />existing at the time of observation over a large geographical area. They reveal in <br />a few minutes what otherwise would take hours to describe. The United States Weather <br />Bureau issues information about approaching storms, floods, frosts and all climatic <br />conditions in general. Twice a month it issues a 30-day &ldquo;outlook&rdquo; which is a rough <br />guide to weather conditions likely to occur over broad areas of the United States. <br />These 30-day outlooks are based upon an analysis of the upper air levels which often <br />set the stage for development of air masses, fronts and storms. <br />Considerable effort is being exerted today to achieve more accurate weather <br />predictions, with identifying and tracking storms over regions which have but few <br />meteorological（气象）stations. Extensive experiments are also in progress for <br />weather modification studies. <br />6.

The thirty-day forecast is determined by examining _____ <br />A. daily weather maps B. upper air levels <br />C. satellite reports D. changing fronts <br />8.
