If you dream of going someplace warm to escape the cold winter weather,a trip to a recently discovered planet would certainly warm you right up.The planet,named
OGLE-TR-56b,has temperatures of more than 3,000°F.“This is the hottest planet we know about,”says Dr Dimitar Sasselov,a scientist who led the discovery team.“It is hot enough to have an iron fog and to rain hot iron droplets(细沫).”
The new planet is 30 times farther away than any planet discovered by scientists
before.It is in the Milky Way(银河)but it is not in our solar(太阳的)system.The new planet moves around a star much like our sun,however scientists discovered the planet by using a new planetsearching method called transit technique.They were able to catch sight of the planet when it moved in front of its star,causing the star's light to dim(变暗).Scientists compare the method to discovering the shadow of a bee flying in front of a searchlight 200 miles away.“We believe the door has been opened wide to go and discover planets like the Earth,”says Sasselov.

1.此题考查考生进行推理判断的能力。文中第一段最后作者提到的iron fog只是一种比喻，来表明这颗行星温度之高，并不能由此推断它的上面有铁。A是不成立的。文中第一句话：如你梦想着去一个温暖的地方以躲避寒冷的冬季，那么到新近发现的一个行星上去会让你立刻暖和起来。这句话是为了引起下文，不能作为推断的依据，因此，B选项错误。D选项说科学家们正在研究这颗新星上的天气情况，文中没有提及。文中第二段：科学家们用一种叫做transit technique的新方法发现了这颗新星。这颗星围绕一颗类似太阳的恒星运转。当它转到这颗恒星前面时，使得恒星的光变暗，这时他们就能看见它了。C选项：这颗恒星会阻挡我们的视线，使我们看不到新星。这个推断是正确的。答案为C。
2.其中的D选项与上题观点一致，也就是用来发现新星。答案为D。
3.这道题考查考生概括文章主旨大意的能力。对于这类题，最好的方法就是用假设的方法去判断。因为标题应该在最大程度上覆盖全文。此篇文章主要围绕这颗新星的发现展开。答案为B。
