我在白勇的语法书上做到这两道题分别是
Los Angeles has a higher number of family dwellings per capita than any large city.

A. a higher number of family dwellings per capita than any large city.
B. higher numbers of family dwellings per capita than any other large city.
C. a higher number of family dwellings per capita than does any other large city.
D. higher numbers of family dwellings per capita than do other large cities.
E. a high per capita number of family dwellings, more than does any other large city.

正选：C


Last year, land values in most parts of the pinelands rose almost so fast, and in some parts even faster than what they did outside the pinelands.

A.    so fast, and in some parts even faster than what they did
B.    so fast, and in some parts even faster than, those
C.    as fast, and in some parts even faster than, those
D.    as fast as, and in some parts even faster than, those
E.    as fast as, and in some parts even faster than what they did

正选：E


让我所困惑的不是题目本身，而是在第一道题中，than后面要跟does,而第二道题中，than后面可不可以跟did？

这个than作比较后面要不要跟do 之类的词呢？比如说最简单的I run faster than you.  Than后面就不用跟动词。

白勇书中有提到过，比较从句谓语与主句谓语相同，可用do,did,或does代替。
那么第二个题中是否也可以加did呢？


希望各位有志之士各抒己见帮我解决这个问题，以防在以后的做题中出现博弈的现象，多谢了!

还有个问题就是，这个考试的机位的放名额时间是不是每个礼拜放一点的？希望有经验的同志帮忙解释一下，因为我刚查了山东大学考点6月的位子只有3号可以选，按理说GMAT考试不是每个礼拜都有的么？？？谢谢谢谢~很急的！

第一题than后的does是一种倒装形式，than does any other large city=than  any other large city does。

例：i am better than he is
=    i am better than is he
=   i am better than he （is）此处省略了is
