why引导的特殊疑问句
why为疑问副词,意为“为什么”,用来询问原因、理由,一般由“why+一般疑问句”构成其特殊疑问句。
eg:Why is he here?他为什么在这儿?
以why引导的特殊疑问句,常用because引导的状语从句来回答。because为连词,意为“因为”,其后要接一个句子来陈述原因、理由。
eg:—Why don't you like English?你为什么不喜欢英语?
—Because it's difficult.因为它很难。
【拓展】why还可以用来向别人委婉地提建议,常用句型为“Why don't you+动词原形+其他?”或“Why not+动词原形+其他?”意为“你为什么不做……呢?”
eg:Why don't you/Why not play soccer with us?你为什么不和我们一起踢足球呢?
