我不是高手。我解答这道题的思路是，首先they指代不明。排除A E. 然后注意比较的两方。C将wild animals和that（指fat）比较了，D将fat和livestock比较了，都是不对了。因此选B. 再看A，我觉得错误就在they指代不明。根据曾经做过的题，我觉得do可以省略，也可以保留。 谢谢作者: kudoucliff 时间: 2010-7-30 22:37
谢谢啦~~指出A的错误就行了…… 我总觉得还是不能省……prep语法笔记上说，有宾语的情况下不能省，比如Jim eats more meat than does Tom. 如果省略does的话就会造成歧义“Jim eats more meat than he eats Tom”，但是没有meat的情况下就可以省略does……作者: evilleo 时间: 2010-7-31 12:55
我今天看OG。觉得如果造成歧义的话，还是不应该省的。这种情况也包括系动词be。好多省略都造成歧义。
