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。
