A. which increased five percent during the first three months of this year after it fell B. which had increased five percent during the first three months of this year after it had fallen C. which have increased five percent during the first three months of this year after falling D. with a five percent increase during the first three months of this year after falling E. with a five percent increase during the first three months of this year after having fallen 答案选C 为什么which后面要跟完成时？during不是一般过去时的标志词吗？ after后面为什么跟falling呢？ 求讲解啊啊~作者: mudiduange 时间: 2010-12-23 00:58
第一：现在完成时有两个含义，一是表明过去发生的动作持续到现在；另一个是，已经完成的动作，其作用持续到现在。因为最开始一句，是说这个措施作用很明显（注意用的是are,不是were），表明其作用持续到现在，因此用完成时比较好。
第二，after既可以做介词又可以做连词，但在此处是介词。因为如果是连词，那么after连接是哪两个句子呢？很明显，没有句子和其引导的句子连接。因此不是连接，只能是介词。既然是介词，后面只能跟名词性结构,falling正好满足这个要求。作者: piacia 时间: 2010-12-23 05:49
问一下为什么这里的with主格结构不对呢。。个人感觉D也是可以接受的作者: mudiduange 时间: 2010-12-23 15:14
with a five percent increase, 什么增长了5%呢？ 后面一句修饰的是profit,如果用with,其逻辑主语为result,意思不通作者: gesteven 时间: 2011-1-13 01:59
原来如此，原来如此~~~~谢谢
