我觉得答案为D，倒不是因为时态的问题，因为with the cost of wireless service plummeting的ing，其实说明了过去一年价格都在掉(等于是完成式) 通常SC的错误答案至少有两个问题，这题的第一个错误是兔大说的以While开头有 contrast的含意，下半句跟上半句彼此对立，但更明显的错误应该是parallelism，因为 题目阐述手机价格下降跟使用者日益增加这两个现象导致越来越多人选择在晚上跟周末打 电话，D 选项：with the cost of wireless service plummeting跟（with）mobile phones becoming increasingly common是平行的，但是E选项：has plummeted跟are increasingly common却不是平行的，後者必须改成have become increasingly common才 会平行，所以答案应该是D。 ※ 引述《tootoobenee (A级垂耳兔)》之铭言： : ※ 引述《KobashiKenta (nameless)》之铭言： : : GWD-9-Q3: : : Because of wireless service costs plummeting in the last year, and as mobile : : ---------------------------------------------------------------------------- : : phones are increasingly common, many people now using their mobile phones to : : ------------------------------------------- : : make calls across a wide region at night and on weekends, when numerous : : wireless companies provide unlimited airtime for a relatively small monthly : : fee. : : A.Because of wireless service costs plummeting in the last year, and as mobile : : phones are increasingly common, many people : : B.As the cost of wireless service plummeted in the last year and as mobile : : phones became increasingly common, many people : : C.In the last year, with the cost of wireless service plummeting, and mobile : : phones have become increasingly common, there are many people : : D.With the cost of wireless service plummeting in the last year and mobile : : phones becoming increasingly common, many people are : : E.While the cost of wireless service has plummeted in the last year and mobile : : phones are increasingly common, many people are : : 答案给D 但是详解给 E : : 大家觉得如何呢 我觉得E比较好^^" : 这题好像是争议题, 以前有歪果仁告诉我in the last year要用完成式, 因为in the : last year代表从过去一年来的意思, 有持续发生的概念在, 我想是因为这个原因选E. : 但是在while在句首表达对比之意,句意逻辑上并没有对比之意.应该还是选表达伴随发 : 生的D选项. -- --
