104. In the United States, while the number of foreign-born residents and their children is higher than ever, the percentage of the population they represent is not, in 1910 this group made up 35 percent of the population when compared to 20 percent in 2000.

A. population when compared to 20 percent in 2000

B. population as compared to 2000, when it was 20 percent

C. population, comparing it with 20 percent in 2000

D. population, unlike 2000, with 20 percent

E. population, compared with 20 percent in 2000

Prep给出的答案是E。但是，还是看不懂这句句子。哪位给分析一下 ?

COMPARE TO 是“比作”之意，排除A和B

D中UNLIKE的句型用法不对，排除

-ING形式应该主语为发出动作的，C看不出来这个意思，而且IT在里面会不会存在指代不清。

这类题目好像碰到的情况还是很多，可以好好分析一下。

谢谢ls的回复。对于你的解释我有些异议：“COMPARE TO 是“比作”之意，排除A和B”，这句话说得有些绝对。Longman中得解释说这两个词组意思类似：
compared to/with something：
used when considering the size, quality, or amount of something in relation to something similar

Example1：a 20% reduction in burglary compared with last year

Example2：Compared to our small flat, Bill's house seemed like a palace.

另外，我的问题也不是怎么解答这道题。我只是疑惑这句句子得结构：“in 1910 this group made up 35 percent of the population ”这部分是插入语？如果是的话，那么句子就变成了is not compared with，那么这是什么意思呢 ？不太理解。。。

对这道题我的疑惑是：

1. 在比较中，说compare to绝对错误的说法似乎不对。PERP确实有题目，表示比较，正确答案用了compare to的：

31. A recent review of pay scales indicates that CEO’s now earn an average of 419 times more pay than blue-collar workers, compared to a ratio of 42 times in 1980.

1. that CEO’s now earn an average of 419 times more pay than blue-collar workers, compared to a ratio of 42 times

2. that, on average, CEO’s now earn 419 times the pay of blue-collar workers, a ratio that compares to 42 times

3. that, on average, CEO’s now earn 419 times the pay of blue-collar workers, as compared to 42 times their pay, the ratio

4. CEO’s who now earn on average 419 times more pay than blue-collar workers, as compared to 42 times their pay, the ratio

5. CEO’s now earning an average of 419 times the pay of blue-collar workers, compared to the ratio of 42 times

2. A答案中的“when compared。。。” 读起来比较奇怪，逻辑意思上似乎有些偏差，不知道这算不算也是它的错误。记得以前做过的OG题目中，正确答案没有出现过“when compared。。。”这种结构啊。但是PREP102题目中，大侠笔记上说“when compared”和“compared”是一个意思。

希望讨论一下。

is not, in 1910 应该是;

when compared。。。错，when应该去掉 所以A错
