2017届高考英语复习冲刺阶段经典讲义系列突破阅读理解及书面表达 (5)

　　美文赏析

　　Since 1884，Greenwich Mean Time(GMT)has been the international standard for timekeeping，but it is now under threat from a new definition① of time itself based not on the rotation(旋转)of the Earth，but on atomic clocks.

　　In January the International Telecommunication

　　Union will meet in Geneva to vote on whether to adopt② the new measure，despite protests from Britain.No doubt，the question has hurt Britain's national pride—particularly when the British believe their old rival France is leading the push to change from GMT to the new time standard.

　　GMT is based on the passage of the sun over the zero meridian(经线)line at the Greenwich Observatory in southeast London，and became the world standard for time at a conference in Washington in 1884.France was striving③ for Paris Mean Time at the same conference.

　　In 1972 it was replaced in name by Universal Coordinated Time(UTC)but that in fact remained the same as GMT.

　　UTC is based on about 400 atomic clocks around the world but then

　　corrected with“leap seconds”to correspond to④the Earth's rotational speed，which fluctuates(波动)．As a result，atomic time is slowly diverging(偏离)from GMT.

　　The tiny differences between Earth speed and atomic speed have become a problem for GPS，space

　　exploration and mobile phone networks on which the modern world relies.

　　The meeting will look at the possibilities of abolishing the leap seconds and moving fully to atomic time.The proposal has been opposed by British science minister David Willetts.He said，“We should stick to real time as experienced by humans.Without leap seconds we will lose contact with the reality of Earth's rotation.

　　Eventually our midnight would happen at noon.”

　　China_prefers_the_present_time_standards，saying_that_its_astronomers_want_to_retain⑤_Earth­rotation­based_time.

　　【解题导语】　格林尼治标准时间作为全球通用的时间参考标准已使用了120多年。但格林尼治标准时间可能会成为历史。这种以地球自转为依据的世界时可能会被以原子振荡周期为依据的原子时彻底取代。

　　一、阅读与积累

　　1．攻克疑难词汇

　　①definition n．定义

　　②adopt v．采用，采取

　　All three teams adopted different approaches to the problem.三个队处理这个问题方法各不相同。

　　③strive v．努力，奋斗

　　We encouraged all members to strive for the highest standards.我们鼓励所有成员为达到最高标准而努力。

　　④correspond to与……相符

　　⑤retain v．保持；保留

　　2．攻克疑难句

　　No doubt,

　　the question has hurt Britain's

　　national pride—particularly when the British believe their old rival France is leading the push to change from GMT to the new time standard.

　　结构分析　本句是主从复合句。no doubt作状语，意为“毫无疑问”；when引导时间状语从句；believe后为省略引导词that的宾语从句。

　　尝试翻译　这一提议无疑伤害了英国人的国家自豪感——尤其是当英国认为他们的老对手法国带头推动用新的时间标准代替格林尼治标准时间的时候。

　　二、理解与书面表达

　　1．理解文章主旨

　　The passage mainly tells us that_Greenwich_Mean_Time_is_likely_to_be_replaced_by_Universal_Coordinated_Time.

　　2．理解与书面表达

　　文中画线部分的句子结构是写作中常用的，请你写出此句的类型：________。

　　答案　现在分词作伴随状语

　　3．精通句式：非谓语动词

　　(1)说明：非谓语动词指动词不定式、动名词和分词。

　　众所周知，作文中出现过多的简单句会让人觉得单调乏味，句子与句子之间的关系显得松散；而文章中过多地出现复合句又显得累赘，读起来费劲。恰当地运用非谓语动词(或者介词短语等)对简单句和复合句进行转换，不仅句型多样，句子活泼，而且读起来结构紧凑，言简意明。

　　(2)例句感悟

　　①All the people here like the novel written by Tom.

　　②This is a factory，producing thousands of cars a month.

　　③The firefighters' coming here in time helped us a lot.

　　④We think it very important to speak more English.

　　(3)将下面小短文译成英语

　　北京市有大量的出租车司机，他们每天全心全意地为乘客服务，对北京市的交通发挥着重要作用。他们起早贪黑，赚钱养家糊口。有一次，我下车时不小心把手机忘在了车上，但当我和司机同志联系上之后，他立即

　　开车把手机送到了我的家门口，让我感动不已。
