答案 Glaciers Glaciers are formed in places where the temperatures are extremely cold. This could even include places that are at sea level. / In such cold places it snows most of the year. / Every time it snows, the below layers will compress more, / finally turning into hard ice. / This ice is what forms the glacier. / For a glacier to form and sustain itself, / the amount of snow that falls on it / must be more than the amount of glacier that has melted. / This is the only way in which the glacier will be able to maintain itself / and keep increasing in size. /
解析                         冰川
    冰川是在气温极其寒冷的地方形成，即使是海拔为零的地方也可能形成冰川。这些寒冷的地方几乎常年下雪。每次下雪，下层的雪都会被压得更紧，最终成为坚冰。冰川便是由这些冰构成的。
    冰川形成和维持的条件便是飘落在冰川面上的雪量必须多于冰川的融雪量。这是冰川得以维持下去并增大的唯一途径。
