单项选择题

阅读下面的文章,回答第19—21题。在历法王国里,谁也没有我伟大,我就是历法之魁,通行全世界的公历。我的全名叫格里高利历,人们却喜欢叫我的小名:阳历,因为我是根据地球绕太阳公转一周的时间制定的。我的父亲是儒略历,他也不愧为一代天骄。公元前古罗马人的历法一年有365天,可每两年就需增加22或23天,因此日期常常变换,老百姓经 常弄不清日期。公元前46年,罗马统帅儒略恺撒决定让我父亲掌管历法。父亲行使的权力主要有:一年分为 12个月,单月 31天,双月 30天,唯有 2月是29天。因为在罗马,2月是行刑期,人们认为2月是个不吉祥之月,不能过得太长,所以从 2月中减去一天,这样也符合当时测得地球公转1周的时间。父亲上任不久,儒略恺撒死了,他的侄子奥古斯都当上了罗马帝国的第一任皇帝。他征服埃及和结束国内战争是在8月,为了炫耀自己,奥古斯都 给父亲动了个小手术:用自己的名字“August”作为8月的名称。他还嫌8月是小月,就从2月中抽出一天,加在8月上。又打乱8月后面大小月的顺序,因 而,大月变小月,小月变大月。他的手术很成功,一直到现在还是1、3、5、7、8、10、12为大月,2、4、6、9、11为小月。父亲掌管历法一千多年,虽然工作认真、负责,但是由于过于年迈迂腐,跟不上科学技术的发展,到1582年,所显示的日期和实际的日期已经相 差了10天。这样,罗马教皇格里高利十三世提出,让我接父亲的班。我上班后立即决定把这年的 10月5日改为10月 15日,纠正了父亲的误差。为了使自己更完善,我还规定每400年中取消3个闰日。这样平均年长为365.2425日,比太阳年的实际长度 365.24219日仅差26秒,从此,我就登上了历法至尊的宝座。我的优点很多,一上任就被当时的天主教国家,如罗马、意大利、法国、西班牙等国重用。中国一直到1912年才把我引进。

A.用拟人手法,以自述形式介绍有关历法知识,生动亲切,构思奇特

B.按罗马历法发展的时间顺序组织材料,条理清楚

C.使用大量确凿的数据,保证了说明的准确性、科学性

D.拟人说明与非拟人说明相结合是本文的特点

The National Trust。

The National Trust in Britain plays an increasingly important part in the preservation for public enjoyment of the best that is left unspoiled of the British countryside. Although the Trust has received practical and moral support from the Government, it is not a rich government department. It is a voluntary association of people who care for the unspoiled countryside and historic buildings of Britain. It is a charity which depends for its existence on voluntary support from members of the public. Its primary duty is to protect places of great natural beauty and places of historical interest.

The attention of the public was the first drawn to the dangers threatening the great old houses and the castles of Britain by the death of the Lord Lothian, who left his great seventeenth-century house to the Trust together with the 4500-acre park and estate surrounding it. This gift attracted wide publicity and started the Trust’s “Country House Scheme” Under this scheme, with the help of the Government and the general public, the Trust has been able to save and make accessible to the public about 150 of these oil houses. Lats year, about 1.75 million people paid to visit these historic houses, usually at a very small charge.

In addition to country houses and open spaces, the Trust now owns some examples of ancient wind and water mills, nature reserves, 540 farms and nearly 2500 cottages or small village houses, as well as some complete villages. In these villages no one is allowed to build, develop or disturb the old village environment in any way and all the houses are maintained in their original 16th century style. Over 4,000 acres of coastline , woodland, and hill country are protected by the Trust and no development or disturbances of any kind are permitted. The public has free access to these areas and is only asked to respect the peace, beauty and wildlife.

Over the past 80 years the Trust has become a big and important organization and an essential and respected part of national life. It helps to preserve all that and of historical significance not only for future generations of Britons but also for the millions of tourists who each year invade Britain in search of a great historic and cultural heritage.

We can infer from Paragraph 2 that Lord Lothian_______.

A.Donated all his money to the Trust.

B.Started the “Country House Scheme”.

C.Saved many old country bouses in Britain.

D.Was influential in his time
