　　In the 1950s Torreya Taxifolia, a type of evergreen tree once very common in the state of Florida started to die out. No one is sure exactly what caused the decline, but chances are good that if nothing is done, Torreya will soon become extinct. Experts are considering three ways to address the decline of Torreya.

　　在佛罗里达州，佛罗里达香榧是一种非常常见的常绿乔木。从1950年代开始，佛罗里达香榧数量开始减少，并濒于灭绝。目前尚不清楚导致其濒危的确切原因，但是如果不采取任何行动的话，香榧很可能会灭绝。目前，专家们提出了三个方式去解决香榧数量下降。

　　The first option is to reestablish Torreya in the same location in which it thrived for thousands of years. Torreya used to be found in abundance in the northern part of Florida, which has a specific microclimate. A microclimate exists when weather conditions inside a relatively small area differs from the region of which that area is a part. Northern Floridas microclimate is very favorable to Torreyas growth. This microclimate is wetter and cooler than the surrounding regions relatively dry, warm climate. Scientists have been working to plant Torreya seeds in the coolest, dampest areas of the microclimate.

　　第一个选择是把香榧重新种植在它们已经茂盛生长数千年的原生长地。在拥有特殊微气候的北佛罗里达，香榧树曾经数量众多。所谓微气候是指在一片独立区域内，内部一小部分地区的气候状况同该区域有区别。而被佛罗里达的微气候非常时候香榧的生长。该地区同周围干热的气候不同，是非常潮湿和凉爽的。科学家计划在拥有最冷和最潮湿微气候的地区种植香榧。
