托福写作范文：

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.
