1、单元语法专练,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。以why引导的特殊疑问句,常用because引导的原因状语从句来回答。because为连词,意为“因为”,其后要接一个句子来陈述原因或理由。例如: Why does he come here?他为什么来这儿? Why do you like English?你为什么喜欢英语? Because its interesting.因为它很有趣。 注意:why还可以用来向别人委婉地提出建议,常用句型为“Why dont you+动词原形+其他?”或“Why not+
2、动词原形+其他?”意为“你为什么不呢?”例如: Why dont you/Why not play soccer with us?你为什么不和我们一起踢足球呢?,where引导的特殊疑问句 where为疑问副词,意为“在哪里”,用来询问地点,一般由“where+一般疑问句”构成其特殊疑问句。例如: Where are you from?=Where do you come from?你来自哪里? I am from China.=I come from China.我来自中国。 注意:在疑问副词引导的特殊疑问句中,若句中有be动词时,可直接将be动词放于疑问副词后构成疑问句;若句中有实义动词时
