第 第 1 题【单选题】
【阅读选择】Organisms have a great variety of ways of adapting. They may adapt in their structure, function and genetics, in their development and production of the young and in other respects. An organism may create its own environment, as do warm-blooded mammals, which have the ability to adjust body heat exactly to maintain their ideal temperature despite changing weather. Usually adaptations are an advantage, but sometimes an organism is so well adapted to a particular environment that, if conditions change, it finds it difficult or impossible to readapt to the new conditions.The author cites the behavior of warm-blooded mammals in order to show that a living thing may have the ability______.

B、to remain still when an enemy is near
C、to make food from inorganic chemicals

第 第 3 题【单选题】
【阅读选择】We are so used to our life on the surface of the earth that it can be quite an effort for our mind to break free of all the ideas that we take for granted. Because we can feel that things are heavy, we think of "weight" as being a fixed quality in an object, but it is not really fixed at all. If you could take a one-pound packet of butter 4, 000 miles out from the earth, it would weigh only a quarter of a pound.How much would four pounds of tea weigh if it was taken 4,000 miles out from the surface of the earth?
A、1 pound.
B、2 pounds.
C、3 pounds.
D、4 pounds.
【正确答案】A
【答案解析】本题问的是一磅茶如果被带出离地球表面 4000 英里的地方，重量会是多少？4000 这个数字比较关键，因为在本段最后一句中出现了这个词，一看该句 If you could take a one-pound packet of butter 4, 000 miles out from the earth, it would weigh only a quarter of a pound.只是把名词换了一下，很显然答案就是变成原来重量的四分之一，因此正确答案是 A。
