The production of coffee beans is a huge, profitable business, but, unfortunately, full-sun production is taking over the industry and
 bringing about a lot of damage. The change in how coffee is grown from shade-grown，production to full-sun production endangers the very existence of, certain animals and birds, and even disturbs the world’s ecological balance.
          On a local level, the damage of the forest required by full-sun fields affects the area’s birds and animals. The shade of the forest trees provides a home for birds and other special(物种) that depend on the trees’ flowers and fruits. Full-sun coffee growers destroy this forest home. As a result, many special are quickly dying out.
        On a more global level, the destruction of the rainforest for full-sun coffee fields also threatens(威胁)human life. Medical research often makes use of the forests' plant and animal life, and the destruction of such species could prevent researchers from finding cures for certain diseases. In addition, new coffee-growing techniques are poisoning the water locally, and eventually the world's groundwater.
         Both locally and globally, the continued spread of full-sun coffee plantations (种植园)could mean the destruction of the rainforest ecology. The loss of shade trees is already causing a slight change in the world's climate,
 and studies show that loss of oxygen-giving trees also leads to air pollution and global warming. Moreover, the new growing techniques are contributing to acidic(酸性的) soil conditions.
         It is obvious that the way much coffee is grown affects many aspects many aspects of life, from the local environment to the global ecology.
 But consumers do have a choice. They can purchase shade-grown coffee whenever possible, although at a higher cost. The future health of 
the planet and mankind is surely worth more than an inexpensive cup of coffee.

没有一种给予是理所当然的

    ①老人是菲律宾华侨，在海外奋斗半生。几经浮沉，衣锦还乡的他萌生了济世助人、造福梓里的念头。

    ②于是，老人分别给家乡几所学校的校长写了信，希望每个校长能提供十来个学生的名单，以便他从中确定人选，作为资助对象。

    ③家人嗔怪他的愚昧，既是捐助，何必我程序搞得这样复杂？不如来个快捷方式，譬如通过“希望工程”或者“春蕾计划”，干净利落地了却一桩心愿，岂不是更好？

    ④老人摇摇头说：“我的血汗钱只给那些配得到它的孩子。”哪些孩子才有资格得到资助？是那些家庭贫困的孩子还是优秀生，抑或是特长生？谁也不知道老人心里的答案。

    ⑤名单很快到了老人手里。老人让家人买来了许多书，有《泰戈尔诗集》《纪伯伦诗集》《十万个为什么》等，分门别类地包装好，准备寄给名单上的孩子。家人面面相相觑：这样微薄的礼物是不是太寒碜了？大家断定书中自有"黄金屋"。可翻来覆去也没有找到夹在书中的纸钞。只在书的第一页看到了老人的亲笔赠言：赠给品学兼优的学生xxx。落款是老人的住址、姓名、电话和电子邮箱。

    ⑥家人大惑不解，却也不愿忤逆老人的意愿，只好替他一一寄出那些书。

    ⑦光阴荏苒，老人常常对着电话发呆，又莫名其妙地唉声叹气。从黄叶凋零到瑞雪飘飞，谁也猜不透老人所为何事。

    ⑧家人读懂老人的心，缘于新年前收到的一张很普通的贺卡，上面写着：感谢您给我寄来的书，虽然我不认识您，但我会记着您的。祝您新年快乐！没想到老人竟然兴奋的大呼小叫：“有回音了，有回音了，终于找到了一个可资助的孩子。”家人恍然大悟，终于明白老人这些日子郁郁寡欢的原因，他寄出去的书原来是块“试金石”，只有心存感激的人才会有资格得到他的资助。

    ⑨老人说：“土地失去水分滋润会变成沙漠，人心没有感激滋养会变的荒芜。不知感恩的人，注定是个冷漠自私的人；不知关爱别人，纵使给他阳光，日后也不会放射出自身的温暖，也不配得到别人的爱。”

    ⑩想来也是，没有一种给予是理所当然的，没有什么是必须和应该的；所以，没有一种领受是可以无动于衷、心安理得的，都应心存感激。一朵花会为一滴雨露鲜艳妩媚，一株草会因一缕春风摇曳多姿，                       ，一颗心更应对另一颗关爱的心充满感激之情。
