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 floating round. When ice begins to form in seawater, it forces out salt, which has no place 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. [br] The passage mentions which of the following as being a characteristic of seasonal ice?
选项
A、It is similar in appearance to perennial ice.
B、It is typically filled with fine, veinlike channels.
C、It tastes saltier than perennial ice.
答案
A,C
解析
根据第三句,既然未受过训练的人无法区分两种冰,那么季节性冰和终年冰在外观上是一样的,正确。C项根据文章可知,终年冰的盐分都排出去了,因此季节性冰尝起来更咸,正确。B项根据文章,我们只知道终年冰有这些管道用来排出盐分,季节性冰我们不清楚有没有这些管道,排除。
