【题目】(原创)小明列举了我国南极科学考察队在南极考察时可能遇见的危险,其中不可信的是(

A. 暴风雪在冰原上不停地咆哮,使人晕眩迷途

B. 酷烈的寒冷,给队员留下无情的冻伤印记

C. 遭受暴雨袭击,科考站被淹没

D. 冰雪覆盖冰隙、冰沟,随时有可能吞没考察队员

【答案】C

【解析】本题考查极地的自然环境特点极地酷寒,多狂风,降水稀少。夏季出现极昼时,太阳总在地平线上,但太阳高度小,阳光娇弱无力,根本无法驱散冰原上的寒气。冬季出现极夜时,长夜漫漫,暴风雪在冰原上不停地咆哮。故A不符合题意;16808月,科学家在苏联东方站曾测得-88.3℃的极端最低气温。酷烈的寒冷,住住给队员留下无情的冻伤印记。故B不符合题意;极地酷寒,多狂风,降水稀少,在南极考查不会遭受暴雨袭击。故C符合题意;南极洲98%的陆地为冰雪所覆盖,纵横交错的冰隙,冰雪覆盖的冰沟随时有可能吞没考察队员。故D不符合题意。故选C。
