英语翻译It is not so much the language as the cultural backgroun

not so much A as B 与其说A不如说B。没有比较的意思,只是单纯的阐述观点。 His style of argument in the meeting is not so much aggressive as pertinactious。他在会议上的态度与其说是锋芒毕露,不如说是各执己见。not as much A as B 与其说A,我更（偏爱）B。暗含有比较的意思。这是我查的not so much 。。as。。的意思,所以我认为上句可翻译为: 与其说是语言令这本书难理解,不如说是书中的文化背景使其难理解。
