新托福综合写作范文:土星卫星不同寻常特征

本文为2017年2月18日托福综合写作解析及范文

新托福综合写作回顾

阅读主要观点提取：

土星最大的卫星Titan存在三个无法解释的不同寻常的特征。

第一，Titan的轨道是椭圆形elliptical而不是常规的圆形circular。

第二，Titan的两极地区存在洼地depressions。这些洼地既不是火山爆发形成的也不是陨石撞击形成的。

第三，Titan上沙丘的坡向与Titan所吹的风向相反。

听力主要观点提取：

最新的研究表明，Titan上的这些特征都可以有合理的解释。

第一，关于椭圆形的轨道。Titan并不是单一的卫星，而是多个卫星碰撞collide后合并merge在一起的。每次的碰撞，都会形成一定的冲击力impacts，这种冲击力就会改变轨道。随着时间的推移，轨道就变成椭圆形elliptical。

第二，关于洼地。Titan上洼地的形成类似于地球上的洞穴caves。由于Titan上有降雨rainfall，并且降雨集中在Titan的两极地区。所以Titan两级地区的岩石被雨水分解dissolve,形成depressions。

第三，关于沙丘的朝向。Titan上的沙子很重，一般的风吹不动。Titan每年会有几次风力很大的朝东吹的风暴storms，它的风力是平常风的十倍，可以将沙子往东吹。

新托福综合写作范文：

The reading passage claims that there are three unusual features about Titan that cannot be explained, while the speaker thinks that each of the features has a reasonable explanation.

To begin with, the reading states that the orbit of the Titan is elliptical rather than circular, which is quite puzzling and abnormal. According to the lecture, however, this phenomenon is caused by the fact that Titan is originally not a single moon but the combination of several smaller moons, which compounds its orbit. The orbit is shifted by the force of each colliding slightly and becomes elliptical over time.

In addition, the author argues that the existence of depressions in Titan's polar areas is dubious, since they cannot be explained by volcanic activities or meteorite impact. The professor refutes this argument by pointing out that there are frequent rainfalls in Titan and it is those liquids that formed the multiple caves on Titan, as the case on earth.

Finally, contrary to the belief in the passage that the slope of the dunes on Titan is not in compliance with the force of the wind, the lecturer contends that the sand on the moon is so heavy that only those storm winds, ten times stronger than the usual wind, can determine the eastward slope of the dunes.
