同学你好～

Every time he wanted to come into the garden he would bark until someone opened the gate.
这句话的would用来表示过去习惯性动作或倾向，从every time可以看出。例如：
Occasionally he would come to see us．他偶尔会来看望我们。
Every afternoon they would play together．他们每天下午都在一起玩。

This time he was barking so that someone would let him out.
这句话的would用于过去情况，表示“愿意”(相当于will的过去式)。例如：
No matter what happened，he would not say a word．不管发生什么情况他一句话也不肯说。
He would never enter that house again. 他再也不愿进那个家。

情态动词will与would七大用法归纳：
