有道英语阅读理解题,应该选哪个?请解析
I am a writer.I spend a great deal of my time thinking about the power of language—the way it can evoke(唤起) an emotion,a visual image,a complex idea,or a simple truth.Language is the tool of my trade.And I use them all—all the Englishes I grew up with.
31.By saying “Language is the tool of my trade”,the author means that __D____.
A.she uses English in foreign trade
B.she is fascinated by languages
C.she works as a translator
D.she is a writer by profession

答案应该是D,因为段落前第一句就已经提示作者是个作家,D答案意思是“她是一个专业的作家”,所以答案应该选D请问B选项怎么理解?B选项 的意思是她对语言情有独钟,被语言所迷住了你可以翻译一下Language is the tool of my trade这个句子吗?特别是trade在这个语境中如何翻译,谢谢这句话是带着一种修辞手法的意味,trade的意思是多种的,可以表示交易,交换,行业,手艺等意思,在这里的意思是交流的意思,整个句子的意思是“语言是我交流感情的工具”说明她是专业的作家
