Lesson 55 文本  Not a gold mine 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.  文本解析 一）词汇学习Word study 1. use, be used to与used to（1）use通常为及物动词，表示“用”、“使用”、“运用”、“应用”等：May I use your dictionary/ car?我可以用一下你的字典／汽车吗？I don't know how to use the word.我不知道如何使用这个单词。The machine has been used to detect gold which has been buried in the ground.这机器已被人们用来探测地下埋藏的金子。（use用于被动语态，后面的to引导表示目的的不定式，不可与be used to及used to混淆） （2）be used to表示“习惯于”，后面跟名词或动名词，be也可用 get等代替：I'm used to shopping alone.我习惯于一个人购物。I'm used to getting up early.我习惯于早起。I soon got used to getting up early when I started working as a baker.我开始当面包师不久就习惯早起了。 （3）used to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：I used to get up early when I worked as a baker, but I don't have to get up early now.当面包师的时候，我常起得很早，不过我现在用不着早起了。You didn't use to smoke.你过去不抽烟。You never used to smoke.你过去从不抽烟。（用never的否定式更常见） 2. gold与golden（1）gold通常为名词，表示“金”、“黄金”、“金币”、“金块”等：The machine showed that there was gold under the ground.这机器显示这儿的地底下有金子。He loves gold more than anything else.他爱金子胜过一切。当gold作形容词使用修饰其他名词时，它往往表示“金的”：When Frank retired, they gave him a gold watch.弗兰克退休时，他们送了他一块金表。 （2）golden通常为形容词，表示“金色的”、
