【題目】極地游指到地球南北兩極地區(qū)的觀光、探險旅游活動，6 月至 8 月是北極游、12至次年

2月是南極游的最佳時間。根據(jù)材料完成 下列各題。

【1】南、北極游過程中均能看到的景觀是

A. 成群結隊的企鵝 B. 廣闊無邊的森林

C. 形態(tài)各異的冰山 D. 冰屋聚集的村莊

①空氣潮濕 ②狂風暴雪 ③缺乏淡水 ④氣溫過低

A. ②③ B. ①② C. ①③ D. ②④

【答案】

【1】C

【2】D

【解析】南北兩極地區(qū)由于緯度高，太陽輻射弱，氣溫低，有各式各樣的冰山，氣候寒冷，有儲量豐富的淡水資源。

【1】南、北極游過程中均能看到的景觀是形態(tài)各異的冰山，成群結隊的企鵝是南極地區(qū)的景觀，聚集的村莊是北極地區(qū)的景觀，兩極地區(qū)都沒有廣闊無邊的森林，故選C。

【2】南極游玩過程中，需要克服的困難是狂風暴雪和氣溫過低，這里氣溫低、氣壓高，空氣干燥，淡水資源十分豐富，故選D。
