Why don't you用法:
“Why don’t you+动词原形+…?”,在这个结构中,为何why don't后面就得用到主语“you”呢?
原因在于“don't”的实质:do not的缩写,里面的do是个助动词,根据词法原则,助动词帮助主动词构成完整的谓语结构,而只有在“句子”中才会用到完整的谓语结构,英语中的句,必须有主语和谓语,主谓完整才叫句,所以用到了why don't,就得有主语you。如:
Why don't you have another try?为何不再试一次呢?
也可以认为,why not +原形动词是简略形式,why don't you是完整形式,如果不想深入理解,就直接记住即可。
Why not go and have a look?=Why don't you go and have a look?您咋不去看看呢?
