retirees in the United States are four times more likely to give regular financial aid to their children as
retirees in the United States are four times as likely to give regular financial aid to their children as it is for them
retirees in the United States are four times more likely to give regular financial aid to their children than
it is four times more likely for retirees in the United States to give regular financial aid to their children than they are
it is four times as likely that retirees in the United States will give their children regular financial aid as they are
题目分析：根据最近的研究，美国的退休人员给他们的孩子经济援助的可能性是接受孩子的经济援助的可能性的四倍
本题主要考察了比较
选项分析：
A选项：比较 要不然是“more...than...”，要不然是“as...as...” 没有more...as...的搭配。
B选项：这个选项用了as...as...的搭配，但是第一个as后面是“give aid”，即谓语宾语成分，但第二个as后面是完整的一句话，成分并不对等。
C选项：正确
D选项：it在这里是形式主语，指代“美国退休人员给孩子们经济援助”这一件事，此时就变成了“这件事是有可能的”；than 后面是“退休人员有可能接受援助”，此时变成了“退休人员有可能去干嘛干嘛”。很明显，并不能“一件事”和“一群人”比较。
E选项：同D
d的问题是for retirees 这个是为了retirees的意思 作状语 这是有问题的 但e不懂哪里错啊
e比较对象不正确。it is likely that中的it是形式主语，指代that后面的一整句话，那么整句话的意思就是：“retirees give children aid这件事" is four times as likely as “retirees” are likely to do sth
茅塞顿开 谢谢老师
老师，“retirees give children aid这件事" is four times as likely as “retirees” are likely to do sth 我怎么觉得这两个比较没问题呢？
retirees give 这件事 as likely as retirees to do
retires will give和 they are不平行
(That retirees in the united status will give their children regular financial aid) is four times as likely as (they are) to receive it from them. 比较的对象是that从句与they (retirees)

为什么曼哈顿prepSC里写，xx times as...as要一起用，不能说xx times more than
time的用法还有xx times sth, 意思是是什么的几倍…
这里怎么xx times more likely 一起用呢…
我也有同样疑惑。。。我也是因为记得曼哈顿里面说的times as。。as不能跟than一起用排除的c
其实我一直不明白为什么要听曼哈顿的。句子改错部分只有很少很少的部分在考查语法，其余的其实考查的是逻辑判断能力。换句话说，只要是符合英语语法的，GMAT考试都是接受的。因此，xxx times more than啊，xxx times as as呀，都是正确的结构，完全没有错误。
关于“比较”本身的问题，请参考这条问答：https://bichu.com.cn/discussion/45

二刷，有as……as多少倍的表达。如three times as much water as previously thought，之前的笔记错误的。（为什么不出一个删评论的功能？）
谢谢建议。删除的功能加上了（没有被人回复过的发言可以被删除）。

a，more as不搭配
b，c 相比 b 不平行
d e it is形式主语不看好
D项it指代不定式to give，变成不定式和后面主系表结构they are to do的比较；
E项it指代that引导的主语从句，变成从句和主系表结构的比较，实则是从句这个事和主系表结构的主语比较；
Split#1: more...than...固定搭配，去掉选项A
Split#2: 平行对比：选项B中，第一个as后面是不定式，第二个as后面是完整的句子，排除。
CONTINUING...
这个题四个机构四个解法 完全不一样 绝了
A选项：比较 要不然是“more...than...”，要不然是“as...as...” 没有more...as...的搭配。
as......as...... as后面的成分要相同。
e比较对象不正确。it is likely that中的it是形式主语，指代that后面的一整句话，那么整句话的意思就是：“retirees give children aid这件事" is four times as likely as “retirees” are likely to do sth
没有as……as多少倍的表达，ron视频有讲过
likely 提前会变成it is likely to 可能做某事
D选项：it在这里是形式主语，指代“美国退休人员给孩子们经济援助”这一件事，此时就变成了“这件事是有可能的”；than 后面是“退休人员有可能接受援助”，此时变成了“退休人员有可能去干嘛干嘛”。很明显，并不能“一件事”和“一群人”比较。
考察比较：
比较级+than
it is four times错误
retirees in the United States are four times more likely to give regular financial aid to their children ✅
four times as as 或者more than
所以A不要 more as
B as likely to as it is 不行
DE 一件事”和“一群人”比较。
D选项：it在这里是形式主语，指代“美国退休人员给孩子们经济援助”这一件事，此时就变成了“这件事是有可能的”；than 后面是“退休人员有可能接受援助”，此时变成了“退休人员有可能去干嘛干嘛”。很明显，并不能“一件事”和“一群人”比较。
B: omit "it is for them" and it will be correct
are 4 times as likely to do...as to do...
are 4 times more likely to do... than to do...
D:it在这里是形式主语，指代“美国退休人员给孩子们经济援助”这一件事，此时就变成了“这件事是有可能的”；than 后面是“退休人员有可能接受援助”，此时变成了“退休人员有可能去干嘛干嘛”。很明显，并不能“一件事”和“一群人”比较。
A这种说法是对的：retirees in the United States are four times more likely to give regular financial aid to their children than
b是因为it is for them错了吗
as,,,,as 里 面的内容不平行

DE 1）不平行 2）they 和them 同一个分句指代了不一样的东西
2其实不是理由，因为任何一个选项里面都有their和them，这两个指代不同

难道是因为句意？gmac从来没有这样考过诶 e的意思是只是四倍 而CD都是五倍的意思
