TPO16-2 Planets in Our Solar System
Paragraph 6
The orderly nature of our solar system leads most astronomers to conclude that the planets formed at essentially the same time and from the same material as the Sun. It is hypothesized that the primordial cloud of dust and gas from which all the planets are thought to have condensed had a composition somewhat similar to that of Jupiter. However, unlike Jupiter, the terrestrial planets today are nearly void of light gases and ices. The explanation may be that the terrestrial planets were once much larger and richer in these materials but eventually lost them because of these bodies' relative closeness to the Sun, which meant that their temperatures were relatively high.
9. In calling the cloud of gas and dust from which the Sun and all the planets are thought to have condensed "primordial," the author means that the cloud was
A. immense in size
B. composed of similar particles
C. present at the very beginning of our solar system's formation O created D. from a great variety of different materials
解析：修辞目的题，修辞点所在句子只是说了一个事实，所以往前看，前一句说太阳系形成的有序性使得天文学家相信太阳系和太阳本身是同时形成的。既然是有序性，后文肯定要开始说这个顺序了，所以答案是C，太阳系形成最初的时候，而且整个段一直在强调时间概念，所以C正确
[6] 太阳系有序的性质使得大部分天文学家得出结论：行星基本形成于同一时间并且构成物质与太阳相同。天文学家们推测，所有行星原始状态的尘埃和气体形成的云状物凝聚，合成物与木星的有些类似。然而，和木星不同的是，如今类地行星上的轻质气体 和冰极度缺乏。有一种解释认为，类地行星曾经体积更大并且物质构成上更为丰富多样，但因为它们距太阳较近致使温度相对较高而最终失去这些物质。
以上就是托福阅读TPO16-2中的修辞目的题及其解析，大家可以在备考的时候参考复习，希望能够帮助大家的考前准备。最后前程百利祝大家都能取得理想的托福考试成绩。
