7.As its sales of computer products have surpassed those of measuring instruments, the company has become increasingly willing to compete for the mass market sales they would in the past have conceded to rivals. (A) they would in the past have conceded to rivals (B) they would have conceded previously to their rivals (C) that in the past would have been conceded previously to rivals (D) it previously would have conceded to rivals in the past (E) it would in the past have conceded to rivals 解析： 1.逻辑：“由于…，该公司越发想去夺取那些它过去会让给竞争对手的大众市场销售” 2.数的一致：从逻辑意思看，划线从句主语代词应指代the company，且从has increasingly..判断，应用单数。排除AB 3.重复： in the past 与 previously，排除C 4.修饰对象：D里的in the past 放最后，就不知道是修饰would have conceded 还是rivals了。排除D，如果是前者，那就是重复问题了 5.省略: 定语从句引导词如在从句里作宾语，则that可省，如作主语，不能省（注意：如果是从句套从句，即此定从被套在其他从句里，最好不省，不然有歧义），本题sales和they之间就是省去了that 的 作者: karentan1 时间: 2011-8-5 17:50
难道后半句是对maket sales 的定语修饰？求解释啊~作者: vissy 时间: 2011-8-11 09:53
定语从句中that可以省略吗???我记得XDF老师说不能省阿作者: vilawe 时间: 2011-8-11 12:05
划线句子就是修饰market sales的，它是个定语从句，that只有在定语从句中作宾语时才可以省略，这个句子里it would in the past have conceded that to rivals, 所以这个that是可以省略的
