位于西北内陆的某市为提升城市品位，追求经济效益，拟定在市郊建设一个高尔夫球场．据了解，修建一个高尔夫球场要占地上千亩，而且要保证“碧草鲜嫩”（经常浇水、施肥、喷洒除虫剂等）．请你结合西北内陆地区的自然环境、人口与耕地的矛盾、资源利用和保护、社会效益等方面情况，给市长写一封信，说服市政府放弃这一立项．

    Have you seen advertisements about hair care products? The models(模特) have shining hair like jewels(宝石). But now making hair shine is no longer the task of hair care products, because hair can be made into real jewels. Believe it or not, a company called LifeGem in the US makes it possible.

    The company is in the business of taking hair from dead people and making them into diamonds(钻石). Now the company plans to make three diamonds using Beethoven's hair to show their latest technology. The work will take about 7 months. In the end, Beethoven's long hair will become three shining diamonds.

    Since the great musician died in 1827, you may wonder where they got Beethoven's hair. A man called John Reznikoff gave the hair to the company. He holds the Guinness World Record for the latest and most valuable collection of celebrity(名人) hair. His collection also includes hair of Napoleon, Albert Einstein, Abraham Lincoln and John F. Kennedy. In total, the collection is worth over five million dollars.

    Though it sounds unbelievable, diamonds made with hair are for the families to remember the dead.
