【Key structures】 表示过去习惯性动作
当我们提到过去某一特定时间时, 我们有时可用 would来代替 used to，有时则不可以，而且 would需要指出具体时间，used to则不需要。 当used to暗示与现在的对照时，不可用would替换：
I used to drink heavily, but I have given up drinking now.
The boy went home. The boy was crying. The boy was beaten. =Beaten by sb, the boy went home, crying. arm(ed) with 可以表示“带着、装着、穿着”等
Don’t worry. I’m armed with an umbrella. You’d better arm yourself with a warm coat.

dream of doing sth.
I dream of flying in the sky.
2、A new machine called 'The Revealer' has been invented and it has been used to detect gold which has been buried in the ground. 过去分词做定语, 表示 “被” n. +called 被称之为……的……
7、In spite of this, many people are confident that 'The Revealer' may reveal something of value fairly soon. in spite of / though / even if 尽管
something of value of表示其所修饰的名词具有某种性质、状况，of加名词 往往让人联想这名词对应的形容词
I never used to eat a large breakfast, but I do now.
当used to描写过去的状态时，也不可与 would互换， would只表示过去特有的习惯或行为：
This sort of novel used to be very popular. 这种小 说过去很流行.
