问题 Choose the correct letter, A, B, C or D.
Write the correct letter in boxes 22-26 on your answer sheet. [br] What is the final effect of the katabatic winds?

选项 A、Increasing the moving speed of ocean current
B、Increasing the salt level near ocean surface
C、Bringing fresh ice into the oceans
D、Piling up the mountainous ice cap respected by mariners

答案 C

解析根据关键词“katabatic winds”定位到原文F段中部“During winter,the howling katabatics sometimes…Recent research has shown that as fresh sea ice forms(当新鲜冰层形成)，it is continuously stripped away(就会被剥离)by the wind and may be blown up to90km in a single day…Since only fresh water freezes into ice…”，由此可见，重力风主要是促成了新鲜冰层进人海洋，所以答案是C。
