每日一句：
65. Some great manufacturers and great service companies may have become too lean in their relentless drive to reduce costs, outsourcing not just their non-core activities but essential ones too.
【结构分析】
本句是一个简单句，首先分析一下结构：逗号前为主句，Some great manufacturers and great service companies是主语，may have become是谓语部分， too lean in their relentless drive to reduce costs是表语，其中too…to…结构，句末的现在分词结构outsourcing not just their non-core activities but essential ones too作伴随状语，进一步补充说明reduce costs的具体内容，其中not just…but…为连接结构。
【词汇】
manufacturer 生产商
lean adj. 瘦的，贫瘠的，v.倾斜
relentless adj. 无情的
in one’s drive to do 驱动做某事
此处翻译难点：too..to…太…不能…+ lean具有否定意思，因此抵消之后可以理解为“热衷于”，与be keen to do同义。
outsource 外购
【参考译文】有些大的制造商和服务供应商热衷于降低成本，不仅把非核心业务外包，而且连核心业务也不放过。
