例二：10.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
the key:C

此题A为何不对？

如果than后不能省略，为何下面例题答案选E？

90.Although Napoleon’s army entered Russia with far more supplies than they had in their previous campaigns, it had provisions for only twenty-four days.
(A) they had in their previous campaigns
(B) their previous campaigns had had
(C) they had for any previous campaign
(D) in their previous campaigns
(E) for any previous campaign
the key:E。

第一个省略肯定是不可以的，因为比较对象就不对等了
第二个的话Although Napoleon’s army entered Russia with far more supplies than for any previous campaign，it had provisions for only twenty-four days
我翻译了一下，虽然N的军队进入Russia比以往任何时候都有更多的供给，它也只有24天的供给。
我觉得这个是主语的比较，在主语比较时是可以省略的，比如i earn more than you 我赚的比你多
但在宾语比较的时候就不可以省略了，比如i earn more money than you我赚钱比赚你多

纠结一下午，看解释说能不能省略有2种判断，
1，than有对应的时间状语====》可Although Napoleon’s army entered Russia with far more supplies than for any previous campaigns, it had provisions for only twenty-four days.这句就没有啊
2.看比较对象有没有变化，变了的不可以省略主语，如og那个今年cars比去年more fuel-effective的句子，和楼主的第一个句子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.
=======》那我现在的疑问是Although Napoleon’s army entered Russia with far more supplies than for any previous campaign, it had provisions for only twenty-four days.句中比较的不是这次的supplies与之前的supplies吗？那就跟cars那个题一样也是比较对象变了啊，不是同样的supplies了，问什么还省略了主谓只剩时间状语？这样不会有歧义吗？

恭候NN来解惑
到底要怎么判断比较中的省略

看了RON SC的截屏讲解，是否省略than后面的helping verbs有两个原则：
1）if they are required by 2-part parallel signals(either..or, both..and etc.)
2) to resolve ambiguity.

楼主的第一个例子than five years ago有明显的歧义，到底是rising number of housing使得the construction industry’s economic health比5年前的更好，还是rising number of housing比5年前更可以使得the construction industry’s economic health变好？所以为了进行clarify，一定要加上than it was five years ago.

而第二个例子不存在这样的歧义，所以不用加helping verbs.

为什么有的比较句than后可以省略，有的不行？
