标题: Prep SC句意求解 [打印本页] 作者: allez_nn 时间: 2020-11-9 22:40 标题: Prep SC句意求解 Navigators have known for thousands of years that the ocean has variable currents, but it is only in the last half century that a reasonably clear picture has emerged of the patterns and causes of ocean currents.
不知有没有NN可以解答一下后半句话到底是什么意思呢？picture是图像的意思吗？怎么理解picture has emerged of the patterns and causes of ocean currents.
谢谢！ 作者: 长丝弓 时间: 2020-11-9 23:28
GmatLa的大神是这样诠释的：
本题主要需要看出划线部分是一个倒装句，它的正确语序是a reasonably clear picture of the patterns and causes of ocean currents has emerged，换句话说，它将谓语动词has emerged 倒装在了主语的定语之前，这是为了躲避主语过长的现象。当然，倒装与否并不影响我们判断对错，倒装仅是为了修辞的需要。
本题划线部分的意思是：一个关于海洋洋流的模式和原因的一个相对来说比较清晰的图画已经出现了。
