不知道怎么回事，离考试还有12天了，从TPO14套开始就不想在做了，打击实在是太重了，我现在感觉非常绝望1 阅读， 发现怎么做都不对，你似乎搞不清它的出题思路，翻译成汉语也做不对答案，我都错10+
2 听力 也很崩溃，今天做TPO15 错了18个，我听力一直是弱项，花了不少功夫，但是还是这样
3 写作，目前发现还是有些写不完，
总体情况，复习3月左右
是考G后考TUO
真是很崩溃~！
我想谈谈我的解题思路，看看到底哪里不对
TPO 15
Paragraph2:Glaciers are open systems, with snow as the system's input and meltwater as thesystem' s main output. The glacial system is governed by two basic climaticvariables: precipitation and temperature. For a glacier to grow or maintain itsmass, there must be sufficient snowfall to match or exceed theannual loss through melting, evaporation, and calving, which occurs when theglacier loses solid chunks as icebergs to the sea or to large lakes. If summertemperatures are high for too long, then all the snowfall from the previouswinter will melt. Surplus snowfall is essential for a glacier to develop. Asurplus allows snow to accumulate and for the pressure of snow accumulated overthe years to transform buried snow into glacial ice with a depthgreat enough for the ice to flow. Glaciers are sometimes classified bytemperature as faster-flowing temperate glaciers or as slower-flowing polarglaciers.
5. According to paragraph 2, surplus snow affects aglacier in all the following ways EXCEPT: ○It provides the pressure needed to cause glacial ice toflow. ○It offsets losses of ice due to melting, evaporation, andcalving. ○It brings about the formation of firn in the snow itburies. ○It results in temperate glaciers that are thicker thanpolar glaciers. 答案是D，我选的是B，因为第一看到surplus， 我就去文章从“surplus snowfall"定位开始往下读，没有B的内容，难到之前谈”sufficient snow"的内容也要算到surplus的内容里面去吗？
6. Paragraph 2 implies that which of the followingconditions 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 答案是B，还是没读懂，不明白
14. Directions:An introductory sentence for a brief summary of thepassage is provided below. Complete the summary by selecting the THREE answerchoices that express the most important ideas in the passage. Some sentences donot belong in the summary because they express ideas that are not presented inthe passage or are minor ideas in the passage. This question is worth 2 points.
Glaciers are part of Earth'shydrologic cycle. ●

Answer Choices
○Glaciers, which at present contain 80 percent of Earth'sfreshwater, form when accumulated snow is compressed and recrystallized intoice over a period of years. ○When there are glaciers on Earth, water is cycled throughthe glacier system but the cycle period may be hundreds of thousands of yearsduring periods of ice ages. ○The glacial system is governed by precipitation andtemperature in such a way that glaciers cannot form in temperate latitudes. ○When glacial ice reaches a depth of 30 meters, the weightof the ice causes ice crystals at the bottom to flow, and the resultingmovement of the glacier carves the landscape. ○If global warming melted the world's glaciers, sea levelwould rise about 60 meters worldwide. ○Glaciers have had little effect on Earth's surfacebecause only 2 percent of Earth's water is currently contained in glaciers, andthere are fewer glaciers now than at most times in the past. 答案：1.2.4， 我选的1,2,5 3选项跟原文是这个意思吗？
发觉自己的理解跟出题的人有很大差异，怎么办啊，没有多少时间了
