新概念英语第二册课文和笔记 Lesson 55:Not a gold mine并非金矿
日期:2011-08-24

参考译文

  最近,找到失踪宝藏的梦想差一点儿变成现实。一种叫“探宝器”的新机器已经发明出来,并被人们用来探测地下埋藏的金子。在靠近海边的一个据说过去海盗常在里面藏金子的岩洞里,这种机器被派上了用场。海盗们过去常把金子埋藏在那个洞里,可后来却没能取走。一支用这种新机器装备起来的探宝队进入了这个岩洞,希望找到埋藏着的金子。当这个队的队长正在检查洞口附近的土壤时,那台机器显示出它的下面埋有金子。队员们异常激动,就地挖了一个两英尺深的坑,但最后找到的是一枚几乎一钱不值的小金币。队员们接着又把整个洞彻底搜寻了一遍,但除了一只空铁皮箱外什么也没找到。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。

【课文讲解】

Dreams come true
Dreams ended
Dream of
dream of doing sth.
I dream of flying in the sky.
Dream of flying in the sky comes true.
一句话只有一个动词,如果再出现动词,可以用and并列连接,也可以变成复合句用when,because连接,还可以使这个动词表示动词意思,但不做谓语,即非谓语动词
过去分词做定语表示"被"
ploughed field
n.+ called
The plane called a "Pilatus Porter"
如果用短语修饰其它词,则把短语放在被修饰词的后边
be used to do  被用来
used to do
同位语从句中的引导词只要一个 that
under the ground
it is said 是插入语 "据说"
used to 常常 
where 修饰 cave
where ; in which 在那儿
This is the river where I swim
would 一般表示从过去看将来,但此处表示"used to"过去常做
She is the girl who is my sister
She is a girl. She is my sister. 变复杂为简单

be armed with
went into the cave
hoping to find
They were armed with
They went to
They hoped to find
如果几个句子的主语是同一事物,则可以把几个句子并为一个句子
在把握中心句子的前提下,注意其它成分的合成,如果是主动关系,用ing形式,保留一个句子做主句,其它的变成非谓语动词
非谓语动词采用何种形式,则根据其与主语的关系,如果是主动关系,用ing形式,如果是被动关系,则用动词的ed形式
主句与其它句子的位置安排要保持句子的平衡,还要注意动作的连贯。
The boy went home.
The boy was crying.
The boy was beaten.
Beaten by sb,the boy went home,crying.
armed with / hoping to find
entrance to / of
under the ground
Tired , I went home.
I went home tired.
形容词短语做状语
Tired of......
two feet deep 数词+量词+形容词
long/wide/high/deep
tall
I am five years old.
数词+量词+形容词结构可以做定语;也可以做表语
The street is wide.
The street is five meters wide.
离名词最近的形容词是最被强调的
in spite of 尽管
though / even if
something of value
of 加名词往往让人联想这名词对应的形容词
of value = valuable
形容词要放在不定代词的后边
something important
something of importance
someone patient
someone of patience
of value = valuable
of small value

【Multiple choice questions】

2.Using this machine,the search party tried to find the gold in a cave near the seashore.

3.Although they examined the cave thoroughly,they only found a small gold coin which was worthless.
although 会引导让步状语从句,which 会引导一个定语从句

4. however 放句首中都可以,要用逗号隔开
