選擇題

On the other hand,on the moon there will be an attraction between the butter and the moon;but the butter will weigh only about one-sixth as much as it does on the earth.This is because the moon is so much smaller than the earth.The amount of gravitational pull that a body produces depends on the amount of material in it.A packet of butter has a gravitational pull of its own;but this is very small in relation to the pull of something as large as the moon,or the earth,or the sun.

We do not feel the gravitational pull of a packet of butter because______.

A.it is too small to have a gravitational pull of its own.

B.its pull is so small that we tend to ignore it.

C.its pull disappears in the presence of the earth's gravitation.

D.it tends to melt and loses its gravitational pull.

正確答案：B

答案解析：本題定位詞是not feel…packet of butter，找到原文中A packet of butter has a gravitational pull of its own； but this is very small in relation to the pull of something as large as the moon,or the earth,or the sun.所以答案是B.C項(xiàng)錯(cuò)在disappear.
