练习材料：
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 party 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.

任务配置：L0+L4
笔记：
1.知识点
（1）mine 本文的意思是“矿，矿山”
（2）revealer 启示者
（3）pirate 海盗，盗印者，盗版者
（4）The pirates would often bury gold in the cave and then fail to collect it.海盗们过去常把金子埋截在那个洞里.但后来却没能取走。
①would在这里不表示过去将来时，而表示过去的习惯性动作，它后面跟动词原形(bury和fail
②fail to do sth表示“未能”、“不能”或“忘记”做某事
③collect的含义之一为“(去)取”、“接”
Don't fail to collect me before you go to the party.去参加晚会之前别忘了接我。
（5）Armed with the new machine…用这种新机器装备起来...
arm(ed) with可以表示“带着”、“装着”、“穿着”等:
Don't worry.I'm armed with an umbrella.别担心，我带着伞呢。
（6）..‘The Revealer’ may reveal something of value fairly soon.……“探宝器”很快就会探出值钱的东西来。
of 表示其所修饰的名词具有某种性质、状况:
The news is of great importance to us.这消息对我们非常重要。
（7）used to表示过去的习愤，would是另一个用于描述过去经常性行为的词，它与used to有时可以互换，有时则不可以，而且would需要指出具体时间，used to则不需要。
①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.我过去喝酒很厉害，但我已戒了。
②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:
They used to awn a car.他们过去有辆车。
③当used to不强调与现在的对比时，可与would互换。但一个故事开头时不用would，必须首先用一般过去时或used to描述背景，然后用would表示习惯性动作:
When I was a boy we always spent/used to spend our holidays on a farm.We
would get up at 5 and we would help milk the cows.我小时候经常在农场度假。我们总是5点起床，帮助挤牛奶。
练习感悟：
学到一个以前没注意过的语法：would而表示过去的习惯性动作。
