Pensions are now viewed as a deferred payment of salary, money ( a worker is compelled to put away to take care of one's ) later years.
A. a worker is compelled to put away to take care of one's
B. that a worker is compelled to put away to take care of oneself in
C. a worker is compelled to put away to take care of oneself in
D. workers are compelled to put away to take care of them in
E. workers are compelled to put away to take care of themselves in
这道题做对了,选E。但是做题过程不对,take care of后面应该是反身代词,所以A D排除,B C E的区别是单复数,不知道突破口在哪,只是感觉如果B对,C肯定也对,that应该可有可无,不足以影响对错,所以选了E。其实这道题不太明白,麻烦老师讲解。

调查1200人对A B C 的喜好,喜欢A的40%,喜欢B的58%,喜欢C的40%,同时喜欢AB的30%,求喜欢C但不喜欢A B的人
题目:A Printer numbered consecutively the pages of a book, beginning with 1 on the first page. In numbering the pages, he printed a total of 189 digits. How many pages are there in the book?
问题:看了中文翻译并听了管老师的讲解,我都没弄明白这个题目的解题思路。的别是对“a total of 189 digits”的处理。
题目:If n is a prime number greater than 3, what is the remainder when n的平方is divided by 12?
问题:当管老师解题时,他出了3个方程式,分别是:
1) n=3A+1, n的平方=9A(square)+6A+1
2) n=3A+2, n的平方=9A(square)+12A+4
3) n=2A+1, n的平方=4A(square)+4A+1
我不明白的点是:这3个方程式是怎么推到或者是一看到题目就这么设出来的?
