【解析】本文介绍了神秘的宇宙：科学家对宇宙做了很多的研究，但是仍有很多的东西没有被发现。太阳系有八大行星，地球是其中之一，和其它行星相比，地球既不热也不冷，所以在地球上有人类，动物和其它的生命，而其它的行星上没有这样的环境。太阳及其行星被称为太阳系，而我们的太阳系是一个更大的群体的恒星和行星的一小部分,称为银河或银河系。科学家在宇宙之中还发现有许多其它的星系，他们发出的光要好多年才能达到我们这里，宇宙有多大，我们难以想象！
.（1）考查时态及语境理解。句意：科学家认为地球上已经有生命亿万年了。根据后面的短语for hundreds of millions of years.可知句子应该为现在完成时，主语life 是单数，故用has +过去分词。所以答案是C。
（2）考查副词辨析及语境理解。句意：然而，我们还没有在其它的行星上发现有生命。A.yet还，用于否定句；B.already已经，常用于肯定句；C.still仍然，还；D.just刚刚；结合句意和语境，所以答案是A。
（3）考查形容词辨析及语境理解。句意：与其它的行星相比，地球既不太热也不太冷。A.cool凉爽的；B.warm温暖的；C.hot热的；D.wet湿的；结合句意和语境，所以答案是C。
（4）考查副词辨析及语境理解。句意：太阳及其行星被称为太阳系，而我们的太阳系是一个更大的群体的恒星和行星的一小部分,称为银河或银河系。此处是修饰形容词的比较级larger，much可以修饰比较级，结合句意和语境，所以答案是D。
（5）考查固定搭配及语境理解。句意：银河系有数十亿的星星，太阳只是其中之一。billions of数十亿的，结合句意和语境，所以答案是C。
（6）考查固定搭配及语境理解。句意：所以宇宙有多大？A.how large多大；B.how far多远；C.how wide多宽；D.how long多长；结合句意和语境，所以答案是A。
（7）考查动词不定式及语境理解。Scientists have sent spaceships to the planet Mars to7photos句意：科学家已经往火星上发射宇宙飞船来拍照。表达目的，应该用不定式，前面有to ,应该是动词原形，结合句意和语境，所以答案是C。
（8）考查名词辨析及语境理解。句意：他们甚至往太阳系以外的地方发射了宇宙飞船。 A.Mars火星；B.the sun太阳；C.the earth地球；D.the solar system太阳系；结合句意和语境，所以答案是D。
（9）考查固定用法及语境理解。句意：然而没有宇宙飞船已经到达足够远到银河系里其它的星球。Enough修饰形容词时要后置，结合句意和语境，所以答案是B。
（10）考查介词辨析及语境理解。句意：当我们夜晚仰望星空的时候，我们可能会想很多：有这么多星星的宇宙，就我们自己吗？太空之外有生命吗？ A.with有；B.without没有；C.by在……旁边；D.on在……上，所以答案是A。
