Q3(问问问):
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.
e貌似没有任何毛病啊,困惑。。。
E, has plummeted in the last year 时态。
总觉得白勇是指 in the last\past + number + years, 不知是不是?
in the last year 和 last year 有什么区别阿
我觉得while强调的是并列关系,with的表达更能反映因果关系。而且with没有歧义,用with更简洁。
请大家指正!
(1)E的错误主要在于其结构:“While…, many people are now using their mobile phones to make calls across a wide region at night and on weekends, when….”
(2)其次,在逻辑关系上,真正让人们用手机在晚上和周末打垮区域电话的原因是“numerous wireless companies provide unlimited airtime for a relatively small monthly fee”,显然,由于此前wireless companies可能把“晚上和周末”认为是黄金时间而收取黄金价格,人们被迫在白天和工作日通话。因此,原句要强调的是这样的一个变化。至于服务费下跌和手机的普遍性,则仅是让原句逻辑结构完整,否则会遗留不必要的assumption。所以用“with”带出更为合适。
while+从句,表示强烈的对比,在这里明显是因果关系,所以E不对
只能D
in the last year是用现在完成时,但这句话的考点不是这里。
这题目有两个考点:1。people要有主谓结构。
2。and对称,E一个是现在完成时,一个是现在进行时,显然不对称。答案是D
