潮汐那道题, 在marine-science网站找到了原句.
出自文章:What Causes Tides and How Do They Influences Marine Life?
原句如下:
Tidal swelling occurs twice a day on both sides of the earth, once when the moon passes overhead, and once when the moon is on the opposite side of the earth. Tidal forces have an appreciable affect only on large bodies -- such as oceans -- and this explains why soup doesn't spill over the sides of the bowl when the moon is full.
划线的那个部分应该就是考题中划线的部分了吧。所以答案应该, "on both sides of the earth... when the moon is on the ... "
拿去用~!
