问题 Beyond the orbit of our planet______the red world of Mars. If you look at it through a telescope, the planet appears to have patches of a blue-green colour, ______ scientists think may be some kind of plant life.
选项 A、lying: on which
B、lay: of which
C、lie: in which
D、lies: which
答案 D
解析 句意：地球轨道之外有一个红色的火星。如果通过望远镜观察，你会发现该星球上似乎有一块块的蓝绿色，科学家认为这或许是某种植物。题干中第一句为状语提前的倒装句，结合主语the red world of Mars和第二句时态，可知应填人lies；第二空引导非限制性定语从句，关系代词在定语从句中作主语，因此填which(其中scientiststhink为插入语)。故答案选D。
