44. In a comparison/contrast essay, what is the "subject by subject" pattern?A. Discussing one point of comparison at a time for both subjects alternatelyB. Discussing all points about subject A first, then all corresponding points about subject BC. Only discussing similarities between two subjectsD. Writing about each subject in a separate essay

本题考查对比/比较类文章中“subject by subject”模式的概念。解题思路是需要明确每个选项所描述的模式特点，然后与“subject by subject”模式的定义进行对比。

• 选项A：“Discussing one point of comparison at a time for both subjects alternately”描述的是逐点比较模式，即交替讨论两个主题的每一个比较点，并非“subject by subject”模式，所以A选项错误。
• 选项B：“Discussing all points about subject A first, then all corresponding points about subject B”意思是先讨论主题A的所有相关要点，然后再讨论主题B的所有对应要点，这正是“subject by subject”模式的定义，所以B选项正确。
• 选项C：“Only discussing similarities between two subjects”只强调讨论两个主题之间的相似性，而“subject by subject”模式既可以讨论相似点也可以讨论不同点，所以C选项错误。
• 选项D：“Writing about each subject in a separate essay”是指分别为每个主题写一篇文章，这与“subject by subject”模式在同一篇文章中对两个主题进行比较的概念不符，所以D选项错误。
