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.

【1题详解】
细节理解题。根据文章第四段的句子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.（遮阳树的丧失已经引起了世界气候的轻微变化，研究表明，给氧树的丧失也会导致空气污染和全球变暖。）可知阳光充足的咖啡生产会带来空气污染和全球气温变暖，故选B。
【2题详解】
推理判断题。根据文章最后一段的句子But consumers do have a choice. They can purchase shade-grown coffee whenever possible, although at a higher cost.（但消费者的确可以选择。他们可以在可能的情况下购买遮阳咖啡，尽管成本较高。）可知，作者的意图是劝说人们购买阴凉处种植的咖啡，这样对环境是有好处的，故选D。
【3题详解】
推理判断题。纵观全文可知，文章介绍阳光充足的咖啡生产会带来的破坏，应该是出自一本农业杂志，故选A。
【4题详解】
推理判断题。文章第一段介绍阳光充足的咖啡生产的话题，二、三、四段介绍了阳光充足的咖啡生产带来的破坏，第五段说服人们去购买对环境有利的阴凉处种植的咖啡，所以是总分总的结构，故选A。
