Last October, a NASA rocket, traveling at a speed of 9,000 kilometers per hour, smashed into a deep, dark hole on the moon’s south pole.
    Upon impact, the Centaur rocket kicked up a cloud of dust and elements from the moon’s surface, creating a so-called "ejecta-plume" that was monitored by NASA’s Lunar Reconnaissance Orbiter, or LRO.
    Scientists analyzed the findings, and preliminary results from this mission suggested that there was some form of water on the moon. NASA lunar scientist Michael Wargo said those days that a wave of findings during the past year makes it certain.
    "We’ve confirmed that there was indeed water ice in the ejecta-plume, and at an abundance that was about 50 percent greater than our initial estimates."
    That means that the impact site has more water than some deserts on Earth.
1. According to the news report, what has happened last October?
2. What did preliminary results from this mission suggest?
选项 A、A rocket has been successfully launched.
B、There was a rocket hitting the moon.
C、A deep dark hole appeared on the moon’s South Pole.
D、There was an amazing finding made by LRO.
答案B
解析 新闻中指出，美国宇航局的一枚火箭以每小时9000公里的速度，撞上月球南极的一个黑暗陨石坑而粉碎。这与B项的“火箭撞月”意思相同。新闻中提到的是美国宇航局的火箭在月球上撞毁，故A项“成功发射火箭”错误。新闻只是提到火箭撞上黑暗陨石坑，而非C项“月球南极出现一个黑暗的深坑”，故排除C。D项“LRO有惊人的发现”都是火箭撞上月球的结果，与问题中的去年10月不相关，也排除。
