新概念英语文本第二册Lesson 71

Lesson 71

A famous clock一个的大钟

First listen and then answer the question.听录音，然后回答以下问题。

Has Big Ben ever gone wrong？

When you visit London， one of the first things you will see is Big Ben，

the famous clock which can be heard all over the world on the B.B.C. If the Houses

of Parliament had not been burned down in 1834， the great clock would never have

been erected. Big Ben takes its name from Sir Benjamin Hall who was responsible for

the making of the clock when the new Houses of Parliament were being built. It is

not only of immense size， but is extremely accurate as well. Officials from Greenwich

Observatory have the clock checked twice a day. On the B.B.C. you can hear the clock

when it is actually striking because microphones are connected to the clock tower.

Big Ben has rarely gone wrong. Once， however， it failed to give the correct time.

1. b

根据课文第3-4行If the Houses of Parliament had not been burned down in 1834 可以判断只有b.符合课文内容，其他3个选择都与课文实际内容不符。

2. d

根据课文第8行Officials from Greenwich Observatory have the clock checked twice a day

可以判断只有d与课文事实相符,其他3个选择都与事实不符.

课文中用的是have sth.done 的形式，那么就是说是official让别人来检查clock, 但是检查clock 的也可以是official啊, 某个official让另外一个人去检查,这个人不是他本人,是另外的officail 也是可以的啊.

3. b

本句前半句陈述的是一个公认的事实，后半句则表示一个经常性或习惯性的动作，应该用一般现在时才符合逻辑，即“每当你到伦敦的时候”。a. will visit c. have visited , d. will be

1.区分build/ found/ erect/establish

•均有“建设，建立，建造”之意。

•build：普通用词，含义广泛，可指一切具体或抽象的建造或建立。

eg.He built a model ship out of wood. 他用木头造了个模型船。•found：侧重打下基础或创办，具体或抽象事物均可用

eg.The pilgrims founded a colony in Portsmouth.清教徒们在普利茅斯创建了一个殖民地。

•erect：侧重指对高而垂直物的建造。使用不如build广泛。

eg.A monument was erected in front of the town hall.一座纪念碑在市政厅前建起。

•establish：着重稳固地建成，可具体指国家、政府、学校或商店等的建立，也可指信仰、信用、名誉、法律、制度、规则等的建立。

eg.The Minister established a commission to suggest improvements in the educational system.

"部长组织了一个研究组,为改进教育制度提供建议。"2.accurate

•注意在指精确时，accurate前不可加too等表达更进一步增加或减少精确程度的词。

•accurate的基本意思是“精确的,精密的”,指由于谨慎细心而精确地固守事实和真理,与事实无出入,含有为避免误差或偏离理想的模式要花费不少精力的意思,可表示提供的信息准确,也可表示掷、射、击等准确,还可以表示某事物“正确无误”。
