作文说的是一家公司在Cookville的factory很好。它每个dollar的什么可以制造10个drill bits,其他工厂就只能做7个。另外,如果把部分machine parts remove了,就能achieve他们的goal. since devote entirely to Cookville is the only way to reduce the overall production cost, the company should dedicate to Cookville and remove the machine parts. 作文我看了好久才看明白,有点绕,这个狗狗也有点残。作者: Sophie90430 时间: 2014-11-28 22:26
