考研中常见的特殊句式包括强调句、倒装句和特殊比较句等。下面是一些例子：

基本结构：It is/was + 强调内容 + that/who + 其它成分。
例子：It was she who bought a book yesterday in my store.
倒装句
完全倒装：谓语动词完全放在主语前面。
例子：Beautiful is she.
部分倒装：
否定词放句首时：Never had I been to your hometown.
Only引导的状语或者状语从句放句首时：only in this way can I study English well.
特殊比较句
结构：使用“so...that...”或“such...that...”结构。
例子：The value of the information he has provided cannot be overestimated.
