几个OG13 的问题求指点

abc791201064

Of all the vast tides ofmigration that have sweptthrough history, maybe noneis more concentrated asthe wave that brought 12million immigrants ontoAmerican shores in little morethan three decades. (A) maybe none is moreconcentrated as(B) it may be that none is moreconcentrated as(C) perhaps it is none that ismore concentratedthan(D) maybe it is none that wasmore concentrated
than

答案是E。  其中选项里面有一个考点是 E中划线的was 。解析认为

In addition, the second part ofthe

Sentence uses the past tenseverb brought,

indicating that the event isover. The verb used in

the comparative constructionmust also be past

tense, x {none) was moreconcentrated than y {the

wave).

我不理解，这里的be动词为什么非要和后面是一致的：我认为这里的is 表示比较的时间，是“现在”比较的，和后面那个brought 是两回事儿，两者不应该有时态上的一致关系。（也就是 过去brought  现在 is more …than .）

请问大家帮我纠正一下这个理解。

这个题目the n1. Of n2.  AB中的having 解析认为修饰了n1  意思上不合理了。对这一点我理解的是n1 是核心词， having 修饰整个短语实际上还是修饰了n1     

后面DE 的with 作为介词结构，怎么就修饰了n2？

15. Many experts regarded thelarge increase in credit

card borrowing in March not asa sign that households

were pressed for cash andforced to borrow, rather a

sign of confidenceby households that they could

safely handle new debt.

A选项解析： The idiomatic choice of words to express the

negation of one clause and theaffirmation of

another is not as... butas..,. The affirmed

clause is incorrectlyintroduced by rather.

Furthermore, the preposition bydoes hot

express the idea thathouseholds are

confidents The placement of therestrictive

clause that they could safelyhandle new debt

after households could also cause confusion.

解析划线部分  为啥cause confusion 了  而且我认为这是confidence 的同位语不是restrictive clause

1. 我不觉的这是个主要问题，或许这种比较也是发生在“过去”，本题主要判断依据不在这里。

2. 这里with是独立主格结构，在这里的作用是后置定语，所以它可以修饰了the compound insect eye。而having在这里是现在分词作状语，需要逻辑主语必须和主句一致，这里必须指The intricate structure，所以在句意上就错了。

3. 这个不是同位语，（建议LZ再去研究下同位语），这是限定性定语从句修饰紧邻名词households，所以cause confusion。

谢谢哈先

不过感觉第三个  应该是WHO COULD SAFELY吧。。。。解析说的cause confusion 就是说 它的定语从句用错啦？
