) 双重否定句与陈述句的转换： （类似于反问句） 一、双重否定句双重否定就是否定两次,即表示肯定的意思，但必须有否定的意义在里面。

例如:“他不是不来”意思是他要来的。

包括有双重否定的句子就是双重否定句。

分析:“不得不”就是双重否定 这句话的原意为：我承认那个本是我的。

(2）幼儿园的小朋友没有一个不喜欢王老师。

“没有一个…不” 就是双重否定词这句话的原句为:幼儿园的小朋友都喜欢王老师.（3）你不会不知道这件事。

分析：“不会不”就是双重否定词双重否定从字面上就知道，是一句话中有两个否定词语,表示肯定的意思。

双重否定句是相对于单纯否定句而言的，它用否定加否定的形式，表达肯定的语意。

可用“没有……不……”“不……不……”如“我不能不被他感动得流下泪来。
