问题 4 In addition to having more protein than wheat does, the protein in rice is higher quality than that in wheat, with more of the amino acids essential to human diet.
选项 A、the protein in rice is higher quality than that in
B、rice has protein of higher quality than that in
C、the protein in rice is higher in quality than it is in
D、rice protein is higher in quality than it is in
E、rice has a protein higher in quality than
答案 B
解析 由于句首是介词+动词形式，首先考虑having的逻辑主语与句子主语是否一致的问题。显然A、C、D中的主句主语protein作having的逻辑主语是逻辑不通的，因而可排除A、C、D。同时我们也可用than wheat does来判定答案应落在B、E间(因为由可比性原则，句中仅rice与wheat具有可比性。而仅B、E的主语是rice)。B、E比较，E中有两个缺陷：(1)比较关系不清楚未补出than之后的that in；(2)用不定冠词a修饰不可数名词protein是不恰当的。
