请教: OG11-75, 省略的原则

75. Salt deposits and moisture threaten to destroy the Mohenjo-Daro exaction in Pakistan, the site of an ancient civilization that flourished at the same time as the civilizations in the Nile delta and the river valleys of the Tigris and Euphrates.

原句正确.

要讨教的是, OG 中为什么反复强调, 此题as 后面如果加了动词(如”did” ) 就awkward and unnecessary呢? 请问,这类问题省略的原则是什么呢?

同时,一个小问题:

同时,一个小问题:

111. As baby emerges from the darkness of the womb with a rudimentary sense of vision, it would be rated about 20/500, or legally bind if it were an adult with such vision.

C. As a baby emerges from the darkness of the womb, its rudimentary sense of vision would be rated about 20/500; qualifying it to be legally bind if an adult.

D. A baby emerges from the darkness of the bomb with a rudimentary sense of vision that would be rated about 20/500; an adult with such vision would be deemed legally blind.

答案是D

关于C, OG 只说分号用的不对. 那么, 如果将分号换成逗号, C 的用法是否也成立呢?

in my opinion, the same as / than 后省略和不省略没有绝对的标准。相对而言，会产生歧义的就必须补上.

给个更绝的例子:

        According to Booker T. Whatley’s recent analysis, planting the same crops as are planted on large farms will lead to economic disaster for the small farmer, who should plan a succession of high-value crops that will provide a year-round cash flow.

(A)correct

the same...as

adj/adv-er than...

如果the same...as或adj-er than...前面的句子有主谓宾，则as或than后面要补加动词，如did，have，is等等，否则不知是和主语比较还是宾语比较

如果前面的句子没有主谓宾，则as或than后面不需要补加动词，补加反而unnecessary
