正确答案为选项C，即玉兔的一些组件已经不再发挥其功能，这从录音内容 两处可知， Its functionality has been weakened its wheels are no longer functioning, nor are its solar panels...。选项A 错误地把玉兔在月球上工作了 5 个多月之后还在继续运行说成了玉兔在月球上停留了将近5 个月。选项B 错在把玉兔于1 月经历了一 次机械控制失常情况说成了通过机械控制进行了一次科学实验。选如D 把为热绝缘 而设计的太阳能光伏板也已经不能正常发挥功能说成了它还在继续发挥功能。

[录音原文]
China's lunar rover Yutu is still alive and functional after more than five months on the moon. Its functionality has been weakened considerably by the cold lunar nights after it experienced a mechanical control abnormality in January. It still sends data back to the earth, but its wheels are no longer functioning, nor are its solar panels designed for thermal insulation during lunar nights.
