As the summer progresses and the fawns grow,they become less dependent on their mother s milk and more dependent on growing plants as food sources.The adult males spend the summer growing antlers and getting fat.Both males and females continue to eat high quality food in the fall insgroupsto deposit body fat for the winter.In the case of does and fawns,a great deal of energy is expended either in milk production or in growing,and fat is not accumulated as quickly as it is in full grown males.Fat reserves are like bank accounts to be drawn on in the winter when food supplies are limited and sometimes difficult to reach because of deep snow. As fall turnssintoswinter,other changes take place.Fawns lose their spotted coat.Hair on all the deer becomes darker and thicker.The change in the hair coats is usually complete by September and maximum hair depths are reached by November or December when winter becomes cold.
5.依据空间顺序展开段落
依据空间的次序进行论述应是有序地由远至近或由近至远,由上至下或由下至上对事物进行描写。下面的例子描写了一幅美丽宁静的夜景。作者先描写空中的月亮,再随洒向大地的月光写到湖四周随风摇曳的树枝,又由青蛙的叫声把读者引到了湖的中央,最后结尾讲:这是一个多么迷人的夜晚。这个段落文字简洁流畅,有序地按空间顺序由上写到下,由外写到里。读者可在平时的练习中注意模仿。
