　　2015年9月13日托福写作机经回忆

　　9月13日托福综合写作题目：

　　关于three explanations for why toucan evolved a bill(the hard pointed or curved outer part of a bird's mouth)的争议。

　　阅读文章：three explanations.

　　1.weapons against predators;

　　2.color and shape to hide from predators;

　　3.get rid of excess body heat.

　　听力进行一一反驳，认为这三个explanation都不合理unconvincing

　　1.Can’t function as weapon. It is made of hollow bones filled with air, so it’s thin and lightweight or else it can’t fly. If it was used as a weapon, it will be easily damaged in activities like jabbing(猛戳);

　　2.They have to call out to each other in order to use the color and shape to blend into surrounding areas. if they do this, they would draw attention from predators;

　　3.Healthy toucans don’t use their bills. They need bills to get rid of heat in the daytime but at night when the temperature is lower, they don’t. they then need to retain body heat;

　　9月13日托福独立写作题目：
