What did the team find
Dreams of finding lost treasure almost came true recently. A new machine called 'The Revealer' has been invented and it has been used to detect gold which has been buried in the ground. The machine was used in a cave near the seashore where--it is said--pirates used to hide gold. The pirates would often bury gold in the cave and then fail to collect it. Armed with the new machine, a search party went into the cave hoping to find buried treasure. The leader of the party was examining the soil near the entrance to the cave when the machine showed that there was gold under the ground. Very excited, the part y dug a hole two feet deep. They finally found a small gold coin which was almost worthless. The party then searched the whole cave thoroughly but did not find anything except an empty tin trunk. In spite of this, many people are confident that 'The Revealer' may reveal something of value fairly soon.

梦想
实现
A new machine called 'The Revealer' has been invented and it has been used to detect gold which has been buried in the ground.
现在完成进行时
检测器
该句是and连接的并列句。called "The Revealer”为过去分词短语作后置定语,修饰machine, which has been buried in the ground是一个定语从句。
be used to detect gold为被动语态，be used to do sth. 表示“被用来干……”
e. g. The stick is used to write on the ground.
The machine was used in a cave near the seashore where -- it is said -- pirates used to hide gold.
where = in which 翻译时译为 “在那儿”，修饰 cave；一个地点状语从句
This is the river where I swim.
被用来
据说
被用来
The pirates would often bury gold in the cave and then fail to collect it.
would 表示过去的习惯性动作, 但此处表示 “used to” 过去常做
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）
He failed to see the reason why they sent him away.
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.
失败
Armed with the new machine, a search party went into the cave hoping to find buried treasure.
我们也不妨模仿一下这一结构,写几个句子:
e. g. Attracted by Lily, I joined the class hoping to improve my English language skills.
Dressed in red, Lily went home, laughing.
过去分词作伴随状语
现在分词作目的状语
Very excited, the party dug a hole two feel deep.
队员们异常激动，就地挖了一个两英尺深的坑。
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.
long/wide/high/deep，人有多高用 “tall”
过去分词作状语
上楼
挖洞
They finally found a small gold coin which was almost worthless.
词汇辨析:worthless, valuable, invaluable, priceless, valueless
1）worthless 无价值
2) valuable 贵重
3) invaluable贵重
4)priceless无价的,特别贵重的
5) valueless 无价值
无价值的
词汇辨析:worth与worthy
e. g. The book is worth reading.
1)worth一般只用作表语，它后面接的动词往往是动名词的形式。
2)worthy可作定语和表语，作表语时作“值得”讲。worthy 作表语，后接不定式
e. g. The problem is worthy to be considered.
worthy of 是一种固定的搭配
e. g. The article is worthy of careful study. The book is worthy of being read.
They finally found a small gold coin which was almost worthless.
In spite of this,many people are confident that' The Revealer' may reveal something of valuefairly soon.
尽管如此，很多人仍然相信“探宝器”很快就会探出值钱的东西来。
尽管
自信
of 表示其所修饰的名词具有某种性质状况，所以of+名词=形容词。
be of great importance to us = be important to usbe of absence
=be absentbe of difference =be different
1 The search party was looking for__________
(a) gold (b) a gold mine

would 与 used to 都能表示过去的习惯动作，但两者有区别：

Grammar
2. used to表示的是过去持续的行为或状态,而would不能。
She used to be a teacher.她过去是老师。
