求教OG12 SC4

4.Of all the vast tides of migration that have swept through history, maybe none is more concentrated as the wave that brought 12 million immigrants onto American shores in little more than three decades.

(A) maybe none is more concentrated as

(B) it may be that noneis more concentrated as

(C) perhaps it is none that ismore concentrated than

(D) maybe it isnone that was more concentrated than

(E) perhaps none was more concentrated than

og说，A 选项中的is 应该用一般过去时态，原因是后面的brought也用的一般过去式。
请教一下，前面have swept是现在完成式的嘛，后面的从句比较应该是现在状态来比较,应该用一般现在时啊。如果用was，虽然后面的句子时态统一了，但是比较就是过去的状态在比较？

这样一来was是不是过去时态不就是反着推了么。。

还有一个语法点要注意的是，既然是涉及比较，就要注意比较对象是否平行一致。


给出E  perhaps none was more concentrated than the wave that brought 12 million immigrants onto American shores in little more than three decades.


看比较对象：一个是none，一个是the wave that brought 12million immigrants...


其实比较的对象是整个【主谓结构】，完整句子应该是perhaps none was more concentrated than was the wave that brought 12 million immigrants onto American shores in little more than three decades.


因为在原句中，标黄的was被省略掉了，所以也就暗指比较对象前后的时态都应该是一般过去时，否则后一个was不可省略。因此，前半句的谓语动词应该用was而非is

俺觉得：the wave 后面补全其实是none of the tides was more concentrated than the wave（was concentrated）

为什么完整的是：
perhaps none was more concentrated than was the wave that brought 12 million immigrants onto American shores in little more than three decades.

而不是
perhaps none was more concentrated than the wave that brought 12 million immigrants onto American shores in little more than three decades was.
was的位置？


关于时态我还是不太明白
这个brought是形容wave的，可是比较是现在的比较呀。
就是说我们现在比较过去的事物，不应该用现在时吗？
用一般过去时会不会隐藏了“现在情况已经不是了”的可能呢？

谢谢大家热心的解释。

搞明白了，嘿嘿！

Of all the vast tides of migration that have swept through history
完成时表示动作完成，
意思是在所有这些历史上的移民潮中，没有一个比得上the wave that brought 12 million immigrants onto American shores 。
当然是过去和过去的比较啊。过去时态没错啊。

谢谢您的解释哈！现在明白了，呵呵

A选项的AS不对，一眼就看出来了。就是那个时态没有看懂。
