语法特训1:why引导的特殊疑问句及其答语
why是特殊疑问词,一般位于句首,意为“为什么”,用来询问发生某事或存在某种情况的原因。
why引导的特殊疑问句句型结构
why引导的特殊疑问句句型结构为“Why+一般疑问句?”,答语为“Because+陈述句。”如:Why are you so happy 你为什么这么高兴?
Because today is my birthday.因为今天是我的生日。
why引导的特殊疑问句还有一种句型结构为“Why don't/doesn't/can't/be not+主语+..?”,意为“…为什么不…呢?”。why后面也可以直接加not,句型结构为“Why not+动词原形+...?”,表示请求、询问或建议。当询问的对象是对方时,“Why not do sth. ”可同义转换为“Why don't you do sth. ”。如:
Why not have a try =Why don't you have a try 你为什么不试一试呢?
because和because of
两者都可以用来回答发生某一事情或存在某一情况的原因,意为“因为…”。但because是连词,后面接句子;because of是复合介词,后面接名词、代词或动名词(短语)。如:I take off the coat because I feel hot.我脱掉外套是因为我感觉热。
I like spring because it's beautiful with trees and flowers.
我喜欢春天是因为它有树和花,很美丽。
She doesn't go to school because of illness(生病).她因病没去上学。
