10.    A large rise in the number of housing starts in the coming year should boost new construction dollars by several billion dollars, making the construction industry’s economic health much more robust than five years ago.
(A) making the construction industry’s economic health much more robust than five years ago
(B) and make the construction industry’s economic health much more robust than five years ago
(C) making the construction industry’s economic health much more robust than it was five years ago
(D) to make the construction industry’s economic health much more robust than five years ago
(E) in making the construction industry’s economic health much more robust than it as five years ago
答案是C
32.    A study commissioned by the Department of Agriculture showed that if calves exercise and associated with other calves, they will require less medication and gain weight quicker than do those raised in confinement.
(A) associated with other calves, they will require less medication and gain weight quicker than do
(B) associated with other calves, they require less medication and gain weight quicker than
(C) associate with other calves, they required less medication and will gain weight quicker than do
(D) associate with other calves, they have required less medication and will gain weight more quickly than do
(E) associate with other calves, they require less medication and gain weight more quickly than
答案是E。

关于比较，到底什么时候应该补出助动词，什么时候不能补？
按照我的理解，10是比较economic health in the coming years and that five years ago, 如果把这一部分单独提出来看应该是
the economic health will be much more robust than it was five years ago. 也就是说主语比较时要补出助动词。
但32也是主语比较啊，为什么又不加了呢？

我的总结是 A do sth。 + adj. (比较级) that ， 比较对象为 sth. 后面可以加
1. that/those +后置定语
2. it/they+ be动词 + 状语
3. + 动词（非助动词，与 do 不同）+状语。 （此种结构用于 比较从句的主语与比较对象相同）。

希望各位指正。

也就是说economic health 是做分词的宾语，是你所列的第2种吧

但32题应该不是第1种情况。

是不是说如果比较主语就不加呢？印象中看到过以前的讨论说比较主语时才加，比较宾语和状语不加。请教DX们，有没有比较权威的说法？

谢谢。

1. 总体原则： 补出比不补好。

2. 在比较前后项时态不一致的情况下，一定要补出。 如10。

3. 选最好的。32. 中E是对的是因为，其它有更明显的错误。 如果有选项跟E一样，又补出动词，一定选它不选E。
