新概念英语第二册课后练习题答案详解(第80课)
新概念英语第二册课后练习题答案详解(第80课)新概念英语第二册课后习题Lesson 801. c根据课文第3-4行，只有c.是课文所暗示的并能说明水晶宫与其他建筑不同的原因，而其他3个选择虽然都与课文内容相符，但都不是水晶宫与其他建筑不同的原因，所以只有选c.是准确答案。
2. b根据课文第10-11行…and the profits from the exhibition were used to build museums and colleges 暗示出博览会是非常成功的，所以只有b. highly successful 是准确的，与课文所暗示的情况相符。
而其他3个选择a. failure (失败)，c. not very profitable (不太获利的) 和d. spoilt by fire (被烧毁)都与课文内容不符。
3. d只有选d. In 才符合语法，因为英语中“在某年”需要用介词in,而其他3个选择都不能用在年代前面，所以选d.4. a本句需要一个同前一句中的A great many(大量的,很多)含义最接近的词组. 才能与前一句意思相接近.a. quite a few(相当多,很多)只能修饰可数名词.b. quite a little(很多,相当多)只能修饰不可数名词c. not too many (不太多)意思与a great many 相反d. very much(很,非常)常做副词,修饰动词.所以只有a. 与 a great many 意思最接近,所以选a5. d该句是用It 作形式主语，后面是动词be 加形容词，需要选一个合适的短语作真正的主语，才能使此句意思完整。
按照语法规则，在这类句子中只有to + 动词不定式或动词+ -ing 形式才能做真正主语。
所以a. for traveling, b. in traveling , c. in order to travel 都不符合语法，只有d. to travel 合乎语法，所以应该选d.6. c前面的短语On arriving in England 是表示时间的，意思是“一到英国”，本句的前面需要一个能引导时间状语从句的连词，才能与前面的短语含义相同，a. On, b. Why 和d. Where 都不能引导时间从句，只有c. when 能够引导时间从句，意思为“当……时候”，所以只能选c.7. a只有a. of 最合乎语法，一般形容词的级后面往往需要介词of 或in 引导的短语作限定语。

Lesson 80 The Crystal Palace【Text】Perhaps the most extraordinary building of the nineteeth century was the Crystal Palace, which was built in Hyde Park for the Great Exhibition of 1851. The Crystal Palace was different from all other buildings in the world, for it was made of iron and glass. It was one of the biggest buildings of all time and a lot of people from many countries came to see it. A great many goods were sent to the exhibition from various parts of the world. There was also a great deal of machinery on display. The most wonderful piece of machinery on show was Nasmyth's steam hammer. Though in those days, traveling was not as easy as it is today, steam boats carried thousands of visitors across the Channel from Europe. On arriving in England, they were taken to the Crystal Palace by train. There were six million visitors in all, and the profits from the exhibition were used to build museums and colleges. Later, the Crystal Palace was moved to South London. It remained one of the most famous buildings in the world until it was burnt down in 1936.【课文翻译】19世纪最不寻常的建筑也许要数水晶宫了，它是为1851年的“世界博览会”而建在海德公园的。

2. b根据课文第10-11行…and the profits from the exhibition were used to build museums and colleges暗示出博览会是非常成功的，所以只有b. highly successful 是准确的，与课文所暗示的情况相符。

3. d只有选d. In 才符合语法，因为英语中“在某年”需要用介词in,而其他3个选择都不能用在年代前面，所以选d.4. a本句需要一个同前一句中的A great many(大量的,很多)含义最接近的词组. 才能与前一句意思相接近.a. quite a few(相当多,很多)只能修饰可数名词.b. quite a little(很多,相当多)只能修饰不可数名词c. not too many (不太多)意思与a great many 相反d. very much(很,非常)常做副词,修饰动词.所以只有a. 与 a great many 意思最接近,所以选a5. d该句是用It 作形式主语，后面是动词be 加形容词，需要选一个合适的短语作真正的主语，才能使此句意思完整。
按照语法规则，在这类句子中只有to + 动词不定式或动词+ -ing 形式才能做真正主语。

2. b根据文第 10-11 行⋯and the profits from the exhibitionwere used to build museums and colleges暗示出博会是非常成功的，所以只有 b. highly successful是准确的，与文所暗示的情况相符。
而其他 3 个 a. failure (失)，c. not veryprofitable (不太利的)和d. spoilt by fire (被)都与文内容不符。
3. d只有 d.

按照法，在句子中只有 to + 不定式或 + -ing 形式才能做真正主。
所以 a. for traveling, b. in traveling , c. in order totravel 都不符合法，只有 d. to travel合乎法，所以 d.6. c前面的短 On arriving in England是表示的，意思是“一到英国”，本句的前面需要一个能引状从句的，才能与前面的短含相同， a. On, b. Why和d. Where都不能引从句，只有 c. when 能引从句，意思“当⋯⋯候”，所以只能 c.7. a只有 a. of最合乎法，一般形容的后面往往需要介of 或 in引的短作限定。

比如：Many a student decides to take part in this long-distance race.3、sth.

Later, the Crystal Palace was moved to South London.这是一个一般过去时的被动语态Move是不及物动词，后加to/into/in加宾语It remained one of the most famous buildings in the world until it was burnt down in 1936.1、这是一个由until引导的时在含有until引导的时间状语从句中，如果句子（主句）的谓语动词是延续性动词（即动作可以延续一段时间的动词），如：work，live，stay，study，play，wait等，那么这个句子（主句）常常用肯定式，表示动作一直延续到until所表示的时间为止。
这时until可译作“直到……为止”。
例如：I'll work until he tells me to stop. 我会一直工作到他叫我停下来为止。
间状语从句2、remain 翻译为“保持仍然是”3、it was burnt down in 1936.是一个一般过去时的被动语态 burn down 为烧毁。
