同意 B the best 是主语部分在比较。在这里do不一定需要补出的『本题是可以省略的,因为total fat是不可数的,与livestock不属于同一类型名次,不会造成have livestock的歧义,less不能修饰livestock』。 日常用语中 A is better than B and worse than C。肯定都是不需要重复谓语is的 Prayer倾向选C,但我认为错误,根据下面2个原句可知 原句是 New York Times, February 19, 2002 query.nytimes.com/gst/fullpage.html?res=9C0CEFD9123FF93AA25751C0A9649C8B63&partner=rssnyt&emc=rss “Wild animals not only have less total fat than livestock fed on grain, but more of their fat is of a kind (omega-3) thought to be good for cardiac health, and less of a kind (omega-6) that promotes heart disease.”
because it has fewer calories, less total fat and more of the kind of essential fatty acids that some research suggests are good.
