在漫长的进化过程中,食物匮乏一直是人类面临的首要威胁。由于食物供应的不确定性和食物不能长期保留,人类一直过着饱一顿、饿几顿的生活,能够最大限度有效利用食物的个体具有生存优势。在经历了反复的饥荒选择后,具有生存优势的个体和他们体内的基因,就会通过自然选择的方式被保留下来。这些基因能在饱餐一顿后刺激大量分泌胰岛素,从而最大限度地转化利用血液中的葡萄糖。虽然这样做的代价是可能导致肥胖,但它对肌体的危害所造成的生存威胁,却直到中年后才会表现出来,而在人类历史的绝大部分时间里,人的平均寿命不到30岁。这段文字意在说明:
A. 古人的生存环境与现代人完全不同
B. 人类的生理结构是自然选择的结果
C. 食物匮乏是人类长期应对的首要问题
D. 肥胖与人类生存繁衍的优势基因相关
阅读理解:请根据短文内容,为每题确定l个最佳选项。 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.The National Trust is a _______.
