Salt deposits and moisture threaten to destroy the Mohenjo-Daro excavation in Pakistan, the site of an ancient civilization flourishing at the same time as those did in the Nile delta and the river valleys of the Tigris and Euphrates.
答案说plural pronoun those cannot refer to the singular civilization and thus lack a referent.
如果把THOSE换成THAT那就是指代an ancient civilization吗？如果是这样的话句子意思不对吧？
所以是不是不能用代词了呢？

一定要用those，因为those指代的是Salt deposits and moisture，不是ancient civilization作者: Claudinethj 时间: 2011-8-8 19:37
不是吧这个答案是错误的噢作者: xyxxyxxyx 时间: 2011-8-9 06:23
因为those在这里有指代Salt deposits and moisture，而不是ancient civilization，所以错了呀，
这里civilizations才是比较对象作者: haoye12321 时间: 2011-8-9 20:11
