Exercise
3、The machine was used in a cave near the seashore where -- it is said -- pirates used to hide gold.
it is said是插入语，“据说”。
where = in which翻译时译为 “在那儿”，修饰 cave；一个地点状语从句
这就是我小时候游泳的河。
This is the river where I swim when I was a child.
This is the river in which I swim when I was a child.
4、The pirates would often bury gold in the cave and then fail to collect it.
fail to do sth. 未能、不能、忘记做某事项 （fail后面接动词不定式表示否定）
collect的含义之一为“（去）取，接”
Don’t fail to collect me before you go to the party.
I’ll collect my post on my way home.
I liked to collect stamps when I was young.
5、Armed with the new machine, a search party went into the cave hoping to find buried treasure.
非谓语动词 被动关系, 则用动词的-ed形式
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“武装、装着、穿着”等
The soldiers were armed to teeth.
You’d better arm yourself with a warm coat.
6、Very excited, the party dug a hole two feet deep.
Very excited, … 形容词短语做状语
Tired of sleeping on the floor, …
Tired, I went home./ I went home tired.（句子顺序不同, 表达的意思也不同）
two feet deep“数词+量词+形容词”结构可以做定语； 也可以做表语
I am five years old.
The street is five meters wide.
long/wide/high/deep
人有多高用“tall”
7、In spite of this, many people are confident that 'The Revealer' may reveal something of value fairly soon.
in spite of / despite 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
The news is of great importance to us.
of value＝valuable 有价值的
of small value 价值很小(= almost worthless)
形容词要放在不定代词的后边
something important =something of importance
someone patient =someone of patience
【Special difficulties】
use, be used to, used to
use vt. 用，使用，运用，应用
May I use your dictionary/car
be used to 习惯于（后面跟名词或动名词，be也可用get等代替）
I soon got used to getting up early when I started working as a baker.
I’m used to shopping alone.
used to 过去常常……（表示过去有而现在通常已不存在的习惯，只用于一般过去时，后面只能跟动词不定式）

You didn’t use to smoke.
Would vs. Used to
would used to
表示过去经常发生的事情
When I was in Shanghai,I would often go swimming with my friends on Sundays.
描写过去 状态
He used to be a waiter,but now he’s a driver.
Would vs. Used to
would used to
有“回想追忆”的意思
When I was young,I would listen to the radio. 现在与过去的对比
I used to stay up late,but now I am beyond that age.
不强调与现在对比可与would互换。故事开头不用would, 先用过去式或used to 描述背景，后用would表示习惯性动作。
When I was a boy we used to spend our holidays on a farm.We would get up at 5 and we would help milk the cows.
would 和used to
1.都可以用来表示已经不存在的习惯或状态，两词可以相互转换。
2.would 可与often, always等词连用，不可以用于一个故事或叙述的开始。used to 用于开始，然后，用would 描述习惯性的动作。
3.在强调与现在对比用used to
4.would 需要指具体时间，而used to 不必。
Would vs. Used to
