not only的倒装

问题描述:

not only的倒装
请问如果像这样的句子Not only did the systematic clearing of forests in the United States create farmland and gave consumers relatively inexpensive houses and furniture,but it also.
后面的gave是用原型还是过去时啊,也就是说第一个倒装句的did对and后面的第二个分句起不起作用?

用原形,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.我是教英语的哦.
