　　同位语比较

　　经典考题

　　In 1973 mortgage payments represented twenty-one percent of an average thirty-year-old male’s income; and forty-four percent in 1984.

　　(A) income; and forty-four percent in 1984

　　(B) income; in 1984 the figure was forty-four percent

　　(C) income, and in 1984 forty-four percent

　　(D) income, forty-four percent in 1984 was the figure

　　(E) income that rose to forty-four percent in 1984

　　解题思路，断句后没有比较结构。

　　B选项时同位语结构

　　新Prep语法笔记- 132. (31556-!-item-!-188;#058&004545)

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

　　(A) that CEO&aposs now earn an average of 419 times more pay than blue-collar workers, compared to a ratio of 42 times

　　(B) that, on average, CEO&aposs now earn 419 times the pay of blue-collar workers, a ratio that compares to 42 times

　　(C) that, on average, CEO&aposs now earn 419 times the pay of blue-collar workers, as compared to 42 times their pay, the ratio

　　(D) CEO&aposs who now earn on average 419 times more pay than blue-collar workers, as compared to 42 times their pay, the ratio

　　(E) CEO&aposs now earning an average of 419 times the pay of blue-collar workers, compared to the ratio of 42 times

　　解题思路：the ratio是同位语结构。

　　A.

　　CEO’s earning ---- blue-collar workers 比较对象不对称;

　　B.

　　a ratio同位语结构，但直接接在blue-collar worker后面，意思错误;

　　C.

　　正确

　　D.

　　CEO’s who错误，CEO’s 是sth不能用who来接

　　E.

　　缺少谓语，compare to的比较对象不对象，前者419 times the pay of blue-collar workers表达的是工资数，而后者42 times是比率。

　　重点在B/C对比，B选项，a ratio that后面的部分可以去掉，去掉后句子是“CEO挣得是蓝领工人的419倍，一个比例在1980年”不成为一个完整句子。
