一个关于比较的问题,把我绕进去了

I have a more pretty dog than his.

I have a more pretty dog than he.

I have a more pretty dog than has he.

这里的比较应该是针对宾语的, 以上三种那种最准确呢

谢谢斑竹,能说说than his有什么问题吗,如果是怕引起歧义把主语和his dog进行比较,那么改成I have a more pretty dog than his dog is. 这样行吗?

还想借这儿再问一个今天困扰我的问题:

根据我以前的总结,在比较中如果有宾语或介词短语, 那么都会尽量要求动词补出

而以下OG的两题

A flourished at the same time as B   没有动词补出

OG12 (C)Because they are growing and are seldom in equilibrium, new small businesses are not subject to the same applicability of formulas for cash flow and the ratio of debt to equity as established big businesses.

这个当然不对,wordy什么的就不说了, 但是og解释有一句are is preferable either before or after established big businesses to complete the comparison

就是说OG认为这里需要动词补出

以上两例我觉得在比较结构上是很相似的,为什么一个需要动词补出,一个不需要呢?希望大家指点一下.

还有一例:

885 sectionA 11

because many residents of the Southeast do not have the same ethnic heritage as Northeasteners

带宾语的比较, 和我举的dog的例子很像, 没有动词补出. 晕!
