...growth in the eurozone and China could surprise on the downside and risks surrounding Brexit remain high.
老师们好，这里有个surprise使用方法我感觉有问题，哪儿有不及物动词使用方法呢！老师们感觉这个句子应该怎么样理解（修改）呢？
.growthgrowth为主语
in the eurozone and China为介词短语作后置定语，修饰名词growth
could surprise为句子谓语
and为并列连词
risks主语
surrounding Brexit后置定语
remain为系动词
high为表语
备注：句子surprise被当作一个不及物动词用了。但surprise只有名词和及物动词使用方法，可以把以上句子改为一个名词，在情态动词后加上系动词be+冠词a
could be a surprise on the downside.修改后为下面句子
growth in the eurozone and China could be a surprise on the downside and risks surrounding Brexit remain high.
备注：抽象名词前加不定冠词表示“抽象名词具体化，即一件让人吃惊的事情”
on the downside 降低中，衰落中，衰减中
