　　not only ... (but) also ... --> 可惜没有针对性例句.

　　* Shakespeare was not only a writer but also an actor.

　　not only do/will/can etc

　　*Not only do the nurses want a pay increase, they want reduced hours as well.

　　à not only … as well …

　　* Not only the grandparents were there but also the aunts, uncles and cousins.

　　* He not only writes his own plays, he also acts in them.

　　(3) AHD，not：

　　当第二部分只是强调第一部分时，在not only 结构里 also 通常省略。

　　(4) Cambridge，not only：

　　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.

　　题目释义：The systematic clearing of forests did sth.…,but it also…

　　考点：

　　1. 平行，关于not only…but also，参见本题后补充说明所摘录的Zeldaw里程碑式的帖子:

　　2. 逻辑为王：

　　如果你一眼看出这个句子考not only，but also于是开始找答案，恭喜你，又上当了。

　　做题的时候要弄清楚句子的意思是递进还是转折,如果是递进not only...but also 没问题,如果是转折的话,就要考虑一下是否是GMAC的陷阱了, but/but also才是表示转折的意思.

　　选项分析：

　　A. not only 位于句首时，所引导的句子要用倒装，give和create是and连接的两个并列成分，而时态已经被did提前，只能用原形，所以这里gave错;But it also在此没有错，例见本题后补充的大全354。

　　B. Which定语从句修饰farmland，逻辑意义错误，是systematic clearing给了consumers houses and furniture，不是farmland。

　　C. But also之前分句缺谓语

　　D. Correct;But it also转折前后句，说明systematic clearing既带来了好东西，也带了坏东西，also的使用，精妙。

　　E. Giving修饰created,改变了原来的句意：并列的两个动作;Not only…but…也可以，例见大全189、241.
