Question

SAT中的语法问题。求帮助！！！！

这个句子是正确的。但是我觉得有点怪。能帮我分析一下结构吗？中间的were she这里用的是倒装？但是又为什么能倒装呢？
Bridget worried that she might not be able to bring back many souvenirs were she to take only one suitcase on vacation.

Answer 1

were she to take only one suitcase on vacation
这是一个倒装句，它的正常语序是：if she were to take only one suitcase on vacation.
也就是说，正常语序需要加一个if,而倒装句省略掉这个if。

追问

谢谢！！
那想问一问在什么情况下才能用这一种倒装呢

追答

在虚拟语气中，当句型含有if时，把if省略掉，句子倒装。如：
If I had known your telephone number, I would have called you.
= Had I known your telephone number, I would have called you.
