【题目】下图中M、N海域均是世界优良渔场。读图回答下列问题。

(1)洋流对渔场的分布有显著影响。说出M、N两支洋流的性质及对沿岸气候的影响。

(2)从大气环流对天气的影响分析,N渔场捕捞作业的天气条件。

【答案】(1)N暖流,增温增湿 M寒流降温减湿

(2)N处终年在西风的作用下,风浪大,多阴雨天气,不利于捕捞作业

【解析】整体分析:本题以局部区域图、洋流等方式呈现信息,侧重基本原理与区域地理等基础知识的综合,考查洋流对地理环境的影响、农业区位等知识,考查学生读图获取和解读信息、调动和运用地理知识的能力。

由低纬度流向高纬度的洋流为暖流,暖流对气候具有增温增湿的作用,由高纬度流向低纬度的洋流为寒流,寒暖流对气候具有降温减湿的作用。

(2)从图中可以看出,N处终年在西风的作用下,形成温带海洋性气候,风浪大,多阴雨天气,不利于捕捞作业。

【题目】C

Moby-Dick (1851) is a novel by Herman Melville, considered an outstanding work of Romanticism and the American Renaissance. Ishmael narrates the crazy quest of Ahab, captain of the whaler Pequod, for revenge(报仇) on Moby Dick, a white whale which on a previous voyage destroyed Ahab's ship and severed his leg at the knee.

Our narrator, Ishmael, signs up as sailor on a whaling voyage to cure depression. On board the Pequod, Ishmael meets the mate honest Starbuck. Captain Ahab remains in his cabin and never shows himself to the crew.

Just when Ishmael’s curiosity about Ahab has reached a fever pitch, Ahab starts appearing on deck and we find out that he’s missing one leg. When Starbuck asks if it was Moby Dick, the famous White Whale, that took off his leg, Ahab admits that it was and forces the entire crew to swear that they will help him hunt Moby Dick to the ends of the earth and take revenge for his injury.

Despite first mate Starbuck’s worries and a variety of bad omens (e.g., all the navigational instruments break, a typhoon tries to push the ship backwards, and the Pequod encounters other ships that have lost crewmembers because of Moby Dick), Ahab insists on continuing to pursue the whale.

Finally, just when we think the novel’s going to end without ever seeing this famous White Whale, Ahab sights him and the chase is on. For three days, Ahab pursues Moby Dick, sending whaling boat after whaling boat after him only to see each one wrecked (使下沉)by the whale. Finally, at the end of the third day, the White Whale attacks the ship itself, and the Pequod goes down with all hands.

Even while his ship is sinking, Ahab, in his whaling boat, throws his harpoon at Moby Dick one last time. He misses, catching himself around the neck with the rope and causing his own drowning death.
