以下几个问题是我在XDF小蓝上遇到的不懂的问题，求各位NN帮帮忙解释一下啊！不胜感激！！！

1.As virtually all the nation's 50 busiest airports are, New York's were built for an age of propellers, before jet planes weighing 800,000 pounds needed over two miles of runway.
(A) As virtually all the nation's 50 busiest airports are
(B) As with virtually all of the nation's 50 busiest airports
(C) Like virtually all of the nation's 50 busiest airports
(D) Like the cities where virtually all the nation's 50 busiest airports are
(E) Like other cities where virtually all the nation's 50 busiest airports are

这个题目基本上没有看懂是什么意思，对于as和like在此的用法也不是很明白，求解！！

2.For the first time in the modern era, non-Hispanic Whites are officially a minority in California, which amounts to a little less than half the population of the state, down from nearly there-quarters only a decade ago.

A. which amounts to a little less than half the population of the state, down from nearly three-quarters only a decade ago
B. which amounts to a little less than half the population of the state, down from a decade ago, when it was nearly three-quarters
C. and that amounts to a little less than half the population of the state, down from a decade ago, when they were nearly three-quarters
D. amounting to a little less than half the population of the state, down from nearly three-quarters a decade ago
E. amounting to a little less than half the population of the state, down from what it was a decade ago by nearly three-quarters

我对这一题中的从句一直很不解，对于定语从句也是多多畏惧，不知道该该怎么解决类似的问题，求指点！动名词amounting在这里究竟是干什么用的啊……

3.Floating in the waters of the equatorial Pacific, an array of buoys collects and transmits data on long-term interactions between the ocean and the atmosphere, interactions that affect global climate.
A.atmosphere, interactions that affect
B.atmosphere, with interactions affecting
C.atmosphere that affects
D.atmosphere that is affecting
E.atmosphere as affects

此题是最让我不解的一道题，单词都认识，就是看不懂，为什么要脸用两个interaction呢？我选的是C……

4.For the last five years the Dutch economy has grown faster than Britain, France, or Germany, with the unemployment rate having remained well below that of the other three countries.
A.Britain, France, or Germany, with the unemployment rate having remained
B.have those of Britain, France, or Germany, and the unemployment rate remaining
C.have Britain, France, and Germany, and the unemployment rate has remained
D.the economy of Britain, France, and Germany, with the unemployment rate that has remained

E.the economies of Britain, France, and Germany, and the unemployment rate has remained

对于这个题，我最想问的是，economy也可以用复数么……指代unemployment rate 的时候用的都是单数呢……

求指点！

答案都选什么呀

果汁软糖

呵呵，不好意思，忘了写上正确答案，谢谢提醒哦

第一题选C

第二题选D

第三题选A

第四题选E

妙妙cathy

第一题as后跟句子，like后跟名词（OG上有讲过），一般都用like,而且要跟主句主语对称。其实看不懂题目也没有关系大概知道意思就可以做题了。

第二题which引导从句修饰先行词比较常见，这里离on-Hispanic Whites太远了，amount to 修饰non-Hispanic Whites

第三题interaction大概就是同位语的意思

第四题economy当然可以复数了，就算前面判断不出来，E后面的从句比D的with简洁啊

1.As virtually all the nation's 50 busiest airports are, New York's were built for an age of propellers, before jet planes weighing 800,000 pounds needed over two miles of runway.
(A) As virtually all the nation's 50 busiest airports are
(B) As with virtually all of the nation's 50 busiest airports
(C) Like virtually all of the nation's 50 busiest airports
(D) Like the cities where virtually all the nation's 50 busiest airports are
(E) Like other cities where virtually all the nation's 50 busiest airports are

个人认为virtually在这里是修饰like，因为后面的主语是New York's (airports),所以只能选C。like sth/sb

as在表示“像”的意思时是作为连词，后面接从句。as you like, as sb did..在本题中，比较的是两个物体，用like比较合适。

2.For the first time in the modern era, non-Hispanic Whites are officially a minority in California, which amounts to a little less than half the population of the state, down from nearly there-quarters only a decade ago.

A. which amounts to a little less than half the population of the state, down from nearly three-quarters only a decade ago
B. which amounts to a little less than half the population of the state, down from a decade ago, when it was nearly three-quarters
C. and that amounts to a little less than half the population of the state, down from a decade ago, when they were nearly three-quarters
D. amounting to a little less than half the population of the state, down from nearly three-quarters a decade ago
E. amounting to a little less than half the population of the state, down from what it was a decade ago by nearly three-quarters

这题我一开始倾向A，后来发现which在这里比较奇怪，amounts to的主语是non-Hispanic Whites，但用which引出的话，就容易有指代混淆的问题，因为最近的名词是California。相比之下，amounting就比较清晰。在这里它不是动名词，而是分词，带出一个状语从句。

至于E，it出现的很奇怪。所以我会选D。

3.Floating in the waters of the equatorial Pacific, an array of buoys collects and transmits data on long-term interactions between the ocean and the atmosphere, interactions that affect global climate.
A.atmosphere, interactions that affect
B.atmosphere, with interactions affecting
C.atmosphere that affects
D.atmosphere that is affecting
E.atmosphere as affects

这题的意思大概就是一排浮标漂在太平洋赤道的水上，收集和传送海洋和空气长期互相作用的数据，这种作用影响全球的气候。所以第二个interactions不可缺，否则后面的that affect global climate很容易不知道修饰谁。选C的话意思就变了。

4.For the last five years the Dutch economy has grown faster than Britain, France, or Germany, with the unemployment rate having remained well below that of the other three countries.
A.Britain, France, or Germany, with the unemployment rate having remained
B.have those of Britain, France, or Germany, and the unemployment rate remaining
C.have Britain, France, and Germany, and the unemployment rate has remained
D.the economy of Britain, France, and Germany, with the unemployment rate that has remained

E.the economies of Britain, France, and Germany, and the unemployment rate has remained

我想这里的economies是对应多国的，所以用复数没问题吧。unemployment rate指是Dutch的，一国的，用单数。

谢谢你，解释得很清晰哦 多谢多谢

请问第三句Floating in the waters of the equatorial Pacific, an array of buoys collects and transmits data on long-term interactions between the ocean and the atmosphere, interactions that affect global climate.的interactions that affect global climate是独立主格结构么？

果汁软糖

不是的 这个跟独立主格有区别 其实我也考虑过是不是独立主格

kittyclock

那它是同位语？
