Question

这道题的答案要详解

-Why don't you put the cake in the fridge?
-It'll stay ______for a week.
A.fresh B.fresly C.freshness

Answer 1

选A。这里的stay用作系动词，后接形容词，构成系表结构。意思是：保持某种状态不变。例如：
My sister stayed single all along.
我姐姐一直是单身。

Stay (keep)still a minute; I want to take your photograph.

稳定一会儿，我要给你照张相。

Answer 2

选A
stay可作半联系动词(link verb)
表示一种状态，后加形容词(adjective)
相当于keep的意思
fresh是形容词
freshly是副词
freshness是名词
故选A.fresh

Answer 3

A stay 在这里相当于一个系动词，后边跟形容词

Answer 4

果断A!相信我。
