A earn more pay than pay(that)B earn A earn more pay than B earn 我觉得应该都可以吧； 参考， OG10-187 In one of the bloodiest battles of the Civil War, fought at Sharpsburg, Maryland, on September 17, 1862, four times as many Americans were killed as (Americans) would later be killed on the beaches of Normandy during D-Day. OG10-132
According to a study by the Carnegie Foundation for the Advancement of Teaching, companies in the United States are providing job training and general education for nearly eight million people, about as many as (people) are enrolled in
the nation’s four-year colleges and universities.
187题省略了Americans，132题省略了people；
更正一下，此题应该是没补全的问题；

1、对主谓宾全的句型主语比较：A do sth than B do.（AB为对等名词，加do是为了显示这是一个可
以发出动作的名词，因而确定是主语，进而确定是主语对比）。时态要据后定。Therebe 句型等同
As a result of the continuing decline in the birth rate,[fewer people] will enter the labor force [in the
1980’s]than (few people省略)did [in the 1960’s and 1970’s], a twenty-year period during which
people born after the war swelled the ranks of workers.
2、对只有主谓（如果主语有定语成分，必须要that/those来指代），没有宾语的句子，因为没有宾语，
只可能有主语比较，因而不需要重复do来确认这是一个可发出动作的主语，所以其比较形式如下：
I eat faster than you.注意与下句区别 I eat apple faster than you do 如果写成 I eat apple faster
than you 按GMAC的理解，从语法上就变成我吃苹果比吃你快，成了宾语比较。逻辑上显然不通。
3、主系表结构的比较与主谓结构相同。如果时态不一致，则需补出助词，如：
The economy of Floridais more diversified than it was ten years ago |
