(A)
Imagine if scientists figured out how humans could live on the moon! But to do
that, we need water. Water is important for drinking, growing food, and even making
air to breathe. The good news is, there might already be ice on the moon! Scientists
have found ice at both the north and south ends of the moon. This is exciting for future
moon explorers.
In 1996, scientists found ice at the bottom of a big hole on the moon near the
South Pole. This area is always in the shadow, so it's really cold, and the ice hasn't
melted. Then, in 1998, other scientists found even more ice near the moon's North
Pole. Scientists believe this ice could be a valuable resource for humans who might
one day live on the moon.
Scientists think there could be more than six billion tons of ice in these cold spots
on the moon! If that's true, we might one day be able to live on the moon because of
all this water ice. Who knows what the future will bring?
41. Why are scientists excited about finding ice on the moon?
A. It can be used to make moon rocks.
B. It can provide water for future moon explorers.
C. It can help guide the explorers to the north end.
D. It can create new holes on the moon.
42. Where did scientists first find ice on the moon?
A. On the moon's North Pole.
B. In a big hole near the South Pole.
C. Near the central part of the moon.
D. In the moon's atmosphere.
43. Why hasn't the ice near the moon's South Pole melted?
A. It is covered by moon rocks. B. The hole traps cold air inside.
C. Sunlight never reaches that area. D. The ice is protected by the spacecraft.
44. How much ice do scientists believe is on the moon?
A. More than six billion tons. B. More than six hundred tons.
C. More than sixty million tons. D. More than six hundred million tons.
45. What could the ice on the moon help people do in the future?
A. Travel to other planets. B. Make moon dust.
C. Study moon rocks. D. Live on the moon.

解析
【分析】
这是一篇科普类事实细节型阅读理解题，解题的核心思路是通过抓取每道题干的关键词，回到原文中定位对应的语句，将原文内容和选项逐一比对，不需要额外主观推理，就能直接选出正确答案。首先先通读全文了解文章大意：本文介绍了月球上发现冰的相关研究，以及这些冰对人类未来登月定居的意义。之后逐题定位：第41题抓关键词"excited about finding ice"，对应原文关于冰的价值的描述；第42题抓关键词"first find ice"，定位最早的发现时间对应的内容；第43题抓关键词"hasn't melted"，找南极区域冰不融化的原因描述；第44题抓关键词"How much ice"，定位原文的数字表述；第45题抓关键词"help people do in the future"，找冰的最终作用的对应语句即可。
【解析】
41. 根据原文第一段可知人类想要在月球生存就需要水，第二段最后也提到这些冰会是未来月球居民的宝贵资源，月球上的冰可以转化为人类需要的水，因此科学家对此感到兴奋，A选项“制作月球岩石”、C选项“引导探索者前往北端”、D选项“在月球上制造新坑”原文均未提及，故选B。
42. 根据原文第二段第一句"In 1996, scientists found ice at the bottom of a big hole on the moon near the South Pole."，这是人类首次在月球发现冰，1998年才在月球北极发现更多冰，因此首次发现冰的位置是南极附近的大坑内，故选B。
43. 根据原文第二段"This area is always in the shadow, so it's really cold, and the ice hasn't melted."，该区域一直处于阴影中，也就是阳光永远无法照射到这里，温度极低所以冰不会融化，A选项“被月球岩石覆盖”、B选项“坑把冷空气困在内部”、D选项“冰被航天器保护”原文均无相关表述，故选C。
44. 根据原文第三段第一句"Scientists think there could be more than six billion tons of ice in these cold spots on the moon!"，科学家认为月球上的冰超过60亿吨，直接对应A选项，故选A。
45. 根据原文第三段"If that's true, we might one day be able to live on the moon because of all this water ice."，月球上的冰可以帮助人类未来实现在月球居住的目标，A选项“前往其他行星旅行”、B选项“制造月球尘埃”、C选项“研究月球岩石”均不是原文提到的冰的作用，故选D。
