倒數第二句最後有提到「glacial ice with a depth great enough for the ice to flow」改寫成B提到的「a thick layer of ice」 (以上內容由美加黃冠文老師提供) ※ 引述《chime0515 (我愛劉德華)》之銘言： : Paragraph2: Glaciers are open systems, with snow as the system's input and : meltwater as the system' s main output. The glacial system is governed by two : basic climatic variables: precipitation and temperature. For a glacier to : grow or maintain its mass, there must be sufficient snowfall to match or : exceed the annual loss through melting, evaporation, and calving, which : occurs when the glacier loses solid chunks as icebergs to the sea or to large : lakes. If summer temperatures are high for too long, then all the snowfall : from the previous winter will melt. Surplus snowfall is essential for a : glacier to develop. A surplus allows snow to accumulate and for the pressure : of snow accumulated over the years to transform buried snow into glacial ice : with a depth great enough for the ice to flow. Glaciers are sometimes : classified by temperature as faster-flowing temperate glaciers or as : slower-flowing polar glaciers. : 6. Paragraph 2 implies that which of the following conditions produces the : fastest moving glaciers? : ○A climate characteristic of the polar regions : ○A thick layer of ice in a temperate climate F Long, : ○Warm summers : ○Snow, firm and ice that have been buried for several years : 答案為B, 不過從最後一句看, 我覺得答案C比較合理耶 : 謝謝解答! -- ▅▅▅▅ ▅▅ ▅▅▅ ▅ ▅▅ ▅▅▅ █ █ █ █▅ █▄█ ▄ █ █▄█ █ █ █ █▄ █◥▅ █ █▅ █ █ 7/2(六)下午2：00美加文教新制GRE&字彙三合一免費講座莫清崴博士/江璞教授主講歡迎蒞臨 http://www.merica.com.tw/event/20110702/ -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 114.36.56.53
