not 应该在 because之前~跟后面but对称~作者: linshigong 时间: 2010-3-25 23:55
idiom.
not just.... but also 相当于 not only... but also 的变体，also应该放在but的后面。作者: elmerliu 时间: 2010-3-26 05:25 标题: which 的用法也有问题吧 which 应该不不能指代 two dozen products accounted for half the increase in spending on prescription drugs，所以我直接排出D,E. 忘了OG上有没有对这点做说明。作者: fengyeming 时间: 2010-3-26 11:47
嗯，是的，新东方也说过which不能指代一句话，不胜感激各位的解释！！！作者: 山炮 时间: 2010-3-26 12:02
2方面吧。which 通常不指代一句话。 Th e placement of also is incorrect 。 此题中主要看平行吧，应该是 not only.. but also. 句子改成了 not only... but...also . 所以说also的位置不对。作者: mastlight 时间: 2010-6-23 11:38

对一种现象的解释都是用现在时的吧.作者: 叶之星 时间: 2010-6-24 00:30
我当时排除E还有一个原因是因为平行。。。原句中not just (because of +名词短语）but also（because+句子）不平行。而正确选项B就平行了，not just by the fact that...but also by the fact that...作者: 红尘道士 时间: 2010-6-24 09:30
