新概念英语第二册：第80课课文详解及语法解析
课文详注 Further notes on the text
1. which was built in Hyde Park…
这是一个非限定性关系从句，修饰逗号前的 the Crystal Palace。
这个从句如果去掉并不影响主句的意思。
2.It was one of the biggest buildings of all time…它是有史以来大的建筑物之一……
of all time表示“有史以来”、“空前的”，常与形容词的级连用，表示范围：
He is one of the greatest men of all time.
他是有史以来最伟大的人物之一。
one of+级+复数名词结构的语气比直接用形容词级+名词结构要缓和些，不那么绝对。试比较：
Yesterday was the hottest day of the year.
昨天是今年最热的一天。(语气非常肯定)
Yesterday was one of the hottest days of the year.
昨夭是今年最热的日子之一。(语气缓和些)
3.There was also a great deal of machinery on display. 参展的还有很多机器。
(1)machinery为“机器”、“机械装置”的总称，是集合名词，要与单数动词搭配。某个具体的机器可用 machine或者 a piece of
machinery来表示：
This is a wonderful piece of machinery/a wonderful machine.
这是一台奇妙的机器。
There is a lot of new machinery/There are many new machines in our
factory.
我们厂里有许多新机器。
(2)on display与下面一句话中的 on show同义，都表示“陈列着”、“展示着”，在句子中可以作状语、定语或表语等：
At the Great Exhibition, a great many goods were on display/show.
世界博览会上展出了大量的商品。(表语)
This is the best dress on display/show.
这是展出的的衣服。(定语)
Shall we put all these flowers on display/show?
我们要把所有这些花都陈列出来吗?(宾语补足语)
4. There were six million visitors in all…参观的人数总共是 600 万……
in all为固定短语，其含义之一为“总共”、“合计”：
I paid him ￡ 200 in all.
我一共付给他200英镑。
At the wedding there were over 100 people in all.
参加婚礼的共有一百多人。
5. It remained one of the most famous buildings in the
world…它一直是世界上最的建筑物之一……
remain在这里作系动词，表示“保持不变”、“仍然”(后面可跟形容词、名词、动名词等)：
Why did you remain silent/quiet at the dinner party?
你在宴会上为何一言不发?
They all remained standing while the manager talked.
经理讲话时他们一直站着。
