【2.23】老题多到怀疑来生

今天(2.23)托福考试，大量重复我们寒假集训做过的老题(见下图)。

华华托福十天集训/一个月直通车有两个特点：

第一，集训/直通车对应特定考试日期，报班唯一考虑因素：自己的考试日期和集训/直通车是否对应。

第二，根据不同考试日期的真题重复规律，集训/直通车每个班上课练习的真题题目范围完全不同。

下面是我们寒假集训学员今天考完发来的微信截图，右侧红色的是重复考到的老题日期。

我们帮各位罗列一下今天重复考到的真题日期有：

2014-07-12, 2015-01-25

2015-06-13, 2016-03-11

2016-03-19, 2016-09-25

2016-10-16, 2016-12-10

2017-02-28, 2017-09-23

2018-03-10, 2018-04-21

2018-08-26

只有华华托福拥有2011-2018完整托福真题题库，只有华叔团队具有学术统计和分析能力，专业和非专是有天壤之别的。

华华托福2.25日开课的十天集训和一个月直通车即将满座开班，最后一次提醒各位。

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。

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. （216 Words）
