why not do as your teacher tellls you to?

原题：Why not do sth 固定句式 为什么不做某事
其中as为按照,所以原句的意思是“为什么不按照你老师告诉你的那样做?”as引导的状语从句tell sb.to do sth,do 提前
1.Would you mind doing sth?你介意做某事吗?mind doing,所以用allowing ,后面紧跟的是allow的词组,allow sb to do
允许某人做某事
2.will在委婉语气中一般翻译成“愿意”,will do ,所以原句中用Will you please do sth?do换成give即可,意思是“请问你愿意告诉我用这台机器的方法吗?”
欢迎追问
再问： 请帮最后一个忙，分析一下，1.why don't you as your teachers do? 2.you'd better stay here don't move.
再答： Why don't you =Why not  为什么不做，后面加动词do......，所以我感觉此句少动词成分应该是Why don't you do as your teathers do ?    as 按照   意思是“为什么不按照老师做的那样做？”sb. had better do sth    某人最好做某事  ，所以“你最好呆在这儿”stay用原形，后面是一个祈使句“别动”
