  一般疑问句:是指询问事实的句子,此类句子必须用“yes”,或“no”来回答。

  特殊疑问句:以特殊疑问词(what , where , who , which , when , whose , why , how等)开头引导的句子。此类句子应该问什么就答什么,不能用“yes 、no”来回答。

  e be句型

  There be句型与have, has的区别

  1、There be句型表示:在某地有某物(或人)

  2、在there be句型中,主语是单数,be动词用is ;主语是复数,be动词用are ;如有几件物品,be动词根据最近be动词的那个名词决定。

  8、针对主语提问的特殊疑问句的基本结构是:

  What’s +介词短语?
