GW里的一个答案分析，请大家帮助，谢谢 - ChaseDream

Not only did the systematic clearing of forests in the United States create farmland (especially in the Northeast) and gave consumers relatively inexpensive houses and furniture, but it also caused erosion and very quickly deforested whole regions.

The systematic clearing of forests in the United States not only created farmland (especially in the Northeast), giving consumers relatively inexpensive houses and furniture, but it

刚做到这道题目，发现它根本不可以用not only but also 的形式啊,因为not only but also是表示递进的，而这里却表示转折呢.答案是选A的,应该是错的吧,我觉得应该选D啊,因为前后是转折的关系呢.请大家帮忙分析谢谢。

1. But it also，用法不好，认为此处IT应该被省略，加了it破坏平衡！

2. Not only...but also应该用于递进的逻辑环境之下，但是这道题的意味为转折

ACT也好，ETS也好，他的答案没有absolute term,只是找一个相对最好，能在5个options中都找出错误很正常的

这道题，首先，NOT ONLY， BUT ALSO本身是一个连词性质的组合，前后连两个分句：

第二个分句用了IT，有人说it要省略，我想请问，在这样的情况下，这个it是可省可不省还是“一定要省”？（我个人觉得是可省可不省的，也就是说，不省也不算错，在这个地方，我倒觉得省略了it才是不对的，NOT ONLY后是一个完整的句子，在形式上，BUT ALSO加上了it更为对称）

这道题的逻辑意味一定是转折么？在缺少上下文的支持，我觉得无法判定“create farmland .....VS caused erosion and very quickly
deforested ”就一定是转折，大家认定为转折关系是基于自己对“环保的潜意识”，用JQ老师的话说，审题从正义感的角度出发了。

为什么这道题不可以表示递进关系？一个纯粹的中立角度出发，说明了systematic clearing of forests 这一举措有两个影响，一个是为居民提供了廉价住房，第二个则更为深远--影响了环境，特别从“whole regions”中看出，第二层的意思比起第一层要来得深

因此，从逻辑的角度出发判断A，B错在这点上，小弟愚见认为也是站不住脚的

PS：在前面的帖子里看到也有一位前辈给出了我当时选A的理由，就是在上XDF的时候，老师说过，原文出现了倒装的语法现象要引起注意

出现倒装，原因是：1.语境需要，表示强烈语气表达； 2.为避免出现语法上的头重脚轻现的现象，也就是ETS/ACT所说的“awkward”；

the systematic clearing of forests in the United States created farmland (especially in the Northeast) and gave consumers relatively inexpensive houses and furniture，个人认为，无论是语气上的改变还是所谓“头重脚轻”现象，都使得还原后的正常语序不如原文之倒装！

昨天晚上我已经觉得D是对的了，但是今天早上重新上CD看到了讨论，仔细想想，觉得还是应该A对！
