[求助]GWD17-32

Q32:

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.

1. a reasonably clear picture has emerged of the patterns and causes of ocean currents
2. a reasonably clear picture of the patterns of ocean currents and their causes have emerged
3. a reasonably clear picture emerged of ocean currents, their patterns and the causes of them
4. there have emerged a reasonably clear picture of the patterns of ocean currents and what caused them

E.there had emerged a reasonably clear picture of the patterns of ocean currents and their causes

答案是A。of the patterns ...难道不应该紧跟clear picture做修饰吗？但如果这样的话，"has emerged"就有可能有修饰异议。

怎么感觉GWD的题都是在5个当中选least wrong的呀？不像OG，答案就是答案。

顶一下

请nn讲解下吧

我也觉得，gwd的选项，都不能2-3法。。要每个都看才保险。。

先声明我不是nn。
为避免歧义，要选谓语紧临主语的选项。而of the patterns ...复杂修饰放在后面避免头重脚轻，是很好的句子。这样的句子在高分题里不少，多读读难句就习惯了。[em07]

同意简的说法。而且此题别的选项都可以排除的。

b头重脚轻，而且their 指代模糊。

c their patterns and the causes of them 句中的位置意义不清晰，此短语对称不够。

d e用there be 句型没有理由。
