【答案解析】[听力原文]15-17
Many of the heroes of ail times have been distinguished men of the sea. Such a man was Thomas Scott. Captain Scott performed many brave deeds, but perhaps his most remarkable act was the saving of hundreds men, women, and children who were crossing the Hudson River in a ferryboat. It was winter and the river was full of blocks of ice. As the ferry boat crossed the river, a tugboat ran into it. The collision cut a great V-shaped hole in its side. Men, women, and children were soon screaming with fright as the water poured into the engine room. In a few minutes the boat would have sunk, plunging all the passengers into the icy water.
Fortunately, Captain Scott happened to be passing in a river tugboat. He quickly pulled his boat up to the sinking ship and sprang to its deck. Rushing down to the engine room, he plugged the hole with everything he could find. Still, water came in. Then he thrust his arm into the hole and stopped the water with his body. For an hour he held back the water until the boat reached the dock and everyone was saved.

[解析] 本题题干提到Scott是位英雄，因此他成为英雄的原因应该大多与他如何帮助别人有关，故将答案锁定在[C]和[D]之间。由Then he thrust his arm into the hole...everyone was saved可知答案为[C]。

【正确答案】 D

【答案解析】[解析] 对第15题选项和题干的分析可知，在四个选项中[D]很有可能是答案。再由文中开头部分 Captain Scott performed...was the saving of hundreds men，women，and children可知答案为[D]。

【正确答案】 A

【答案解析】[解析] 由题干中的NOT可确定，录音中没提到的或与原文内容相矛盾的为答案。由...who were crossing the Hudson River...可知[A]不属实，因此为答案。
