GWD-8-Q20:

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.

5. 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

为什么答案不是B？

为什么答案不是B？

这个我也选B，因为它逻辑清晰，平行结构的用法完全符合OG。

我看别的帖子了，很多同学把which理解成the systematic clearing of forests ，这是不对的。which紧接在farmland后面，正确。有几本英汉词典把farmland狭义地译作“农田”，其实英语里它有“农庄”的意思。即a rural area where farming is practiced。只有农庄或者农场能给消费者提供住房和家具，这是常识。通过systematic clearing of forests ，可以开垦出农田（由此到农庄的建立），但决不会是systematic clearing of forests 提供住房和家具。所以A。C。D。E。全都是错的，不但语法错误，而且逻辑错误！

欢迎继续讨论：）

根据原文的意思,应该是the systematic clearing(根据牛津英语大词典,clearing是林中空地的意思)提供的住房.

B的问题在于1)which修饰有歧义;(2)but also后面缺少主语,不对称.

个人意见!

我的意见：

the systematic clearing of forests是指对森林有计划（持续地）采伐，这里作主语，因为有倒装结构，所以正常应该是：

TSCO not only created farmland but also caused erosion 标准的平行结构。

which紧接在farmland后面，是非限制性定语从句，修饰farmland,怎么会有歧义？
