DEER AND THE ENERGY CYCLE 7-8Paragraph When the “energy crisis” first came in 1973-1974, I was living with（忍受） my family in a cabin（小屋） on the edge of an area where deer spend the winter in northern Minnesota, observing（观察） the deer as their behavior changed from（变化） more activity in summer and fall to less as winter progressed, followed by an increase again in the spring as the snow melted（融化的） . It was interesting and rather amusing to listen to the advice given on the radio: “ Drive only when necessary,” we were told. “Put on more clothes to stay warm, and turn the thermostat（恒温器 ） on your furnace（火炉） down.” Meanwhile we watched the deer reduce their activity, grow a winter coat of hair（冬季的厚毛）, and reduce their metabolism（新陈代谢）as they have for thousands of years. It is biologically（生物学上） reasonable（合理的） for deer to reduce their cost of living to increase their chance of surviving in winter.
