e选项好坏，把profit和 efficiency 搞反了

定语从句的先行词同时是宾语从句中的宾语：嵌入式分句

AB错在定语从句修饰的对象错误 try to动作的主语是公司。With its network and the patience of its customers = more preferable

laws/ agreement/directive/initiative +that/doing sth表示法律/协议/规定的具体内容，跟 to do表示法律/协议/规定的最终目的。如laws/ agreement/directive/initiative requiring that……法规要求要如何如何；laws to discourage drunk driving，用来阻止酒驾的法律。

At a recent conference on environmental threats to the North Sea, most participating countries favored uniform controls on the quality of effluents, whether or not specific environmental damage could be attributed to a particular source of effluents, what must, of course, be shown, in order to avoid excessively restrictive controls, is that any substance to be made subject to controls can actually cause environmental damage. 不管能不能把特定的环境破坏归因于特定的污水源.为了避免过度限制,必须表明清楚的是任何要被控制的源头都确确实实会造成环境破坏.

有同样多的员工每周工作时长相同,根据记录,公司O的员工比公司P的员工出现更少的与公伤事故,推出o的员工比p的员工更不容易出现工伤事故. 如果判断为公伤事故的标准不一样, 那么两者的结果之间就没有可比性.
