问题 Arctic sea ice comes in two varieties. Seasonal ice forms in winter and then melts in summer, while perennial ice persists year-round. To the untrained eye, all sea ice looks similar, but by licking it, one can estimate how long a particular piece has been float-
line ing around. When ice begins to form in seawater, it forces out salt, which has no place
5 in the crystal structure. As the ice gets thicker, the rejected salt collects in tiny pockets of brine too highly concentrated to freeze. A piece of first-year ice will taste salty. Eventually, if the ice survives, these pockets of brine drain out through fine, veinlike channels, and the ice becomes fresher; multiyear ice can even be melted and drunk.
Description
The passage describes two varieties of Arctic sea ice and explains how the freezing process causes seasonal ice to taste much saltier than perennial ice. [br] In the context in which it appears, "fine(line 7)most nearly means
选项 A、acceptable
B、elegant
C、precise
D、pure
E、small
答案 E
解析 "Fine" appears in the context of an explanation of how the brine drains out; in such a context, it must be being used to describe a physical characteristic of the channels. In addition, the word "Eventually" implies that the draining is a slow process. Only Choice E, "small," helps to explain why the process is slow and is therefore the best choice. None of the other choices contributes to the explanation.
