The Importance of Astronomy Vocabulary for the TOEFL Exam

Introduction:

The TOEFL exam evaluates the English language proficiency of non-native English speakers. It encompasses various academic subjects, including astronomy. In this article, we will discuss the significance of having a strong vocabulary in astronomy for the TOEFL exam.

1. Enhanced comprehension:

Astronomy vocabulary is crucial for understanding reading passages and listening materials related to astronomy. Familiarity with terms like stars, planets, and galaxies allows test-takers to comprehend the content more effectively. Without a solid understanding of these words, it becomes challenging to grasp the overall meaning and nuances of the passages.

2. Precise communication:

The TOEFL exam requires test-takers to express themselves clearly and accurately in speaking and writing tasks. Having a rich astronomy vocabulary enables candidates to articulate their thoughts and ideas regarding astronomical concepts with precision. This ensures that their responses are coherent and coherent, earning them higher scores.

3. Improved reading skills:

Astronomy passages in the reading section of the TOEFL exam often involve complex scientific concepts. A strong vocabulary in astronomy facilitates the process of skimming and scanning for information, allowing test-takers to quickly identify key details and answer questions more efficiently. It also aids in understanding the relationships between ideas and making inferences.

4. Enhanced listening skills:

The listening section of the TOEFL exam may include lectures or conversations related to astronomy. A good understanding of astronomy vocabulary helps test-takers follow the content and grasp the main ideas and supporting details. This is crucial for answering comprehension questions accurately and effectively.

5. Better writing skills:

Astronomy topics may appear in the writing section of the TOEFL exam, requiring candidates to provide well-developed responses. A strong vocabulary in astronomy enables test-takers to use domain-specific terminology, making their essays more coherent, sophisticated, and convincing. It also allows them to demonstrate a comprehensive understanding of the topic.

Conclusion:

Astronomy vocabulary plays a significant role in achieving success in the TOEFL exam. It enhances comprehension, facilitates precise communication, improves reading and listening skills, and boosts writing abilities. To excel in the exam, it is essential to familiarize oneself with high-frequency English words related to astronomy and practice using them in context.

　　同学们可以把它们汇总到一起集中研究一下天文学哦

　　托福新鲜事丨行星形成并非源于陨星?

　　在托福考试中，天文学是时常出现的一门学科，无论是听力部分还是阅读部分都有它的身影。但是，由于同学们对天文学知识知之甚少，它便“荣登”考生最头疼话题之一。那么针对天文学这个老大难的问题，同学们莫要惊慌。俗话说“九层之台，起于累土”，将基本的天文学词汇及基础天文学知识积累起来并适当关注相关学科发展前沿，面对天文学篇章的时候就能自信满满了!今天博图教育就和大家一起来科普一个天文学新发现!

　　从古至今，人们从来就没有放弃过对太空的幻想和探索。虽然现在人类可以发射载人飞船，实现近距离接触太空的梦想，但最初唤醒人类太空意识的恐怕是那“从天上掉下来的石头”——陨石了。通过研究，人们发现陨石的组成成分同我们地球上的矿石相似，含有最多的元素都是铁，镍，硫，硅，钴，钙，氧等等，均是地球上原有的东西。因此天文界的主流观点认为陨星及其之间的碰撞是宇宙形成的重要基础，陨石球粒是行星的重要组成成分，这也是美国高中自然科学课上所教授的内容。

　　但是，美国一项最新的研究颠覆了传统认知。研究表明，陨星在地球及其他行星邻居的形成过程中所作出的贡献是非常小的。美国麻省理工学院和普度大学的科学家们通过计算机模拟实验发现，当太空中高速运转的大型陨星相互撞击而产生陨石球粒的时候，孕育行星的真正基石——如月亮般大小的行星胚胎早已存在。因此美国专家们得出结论：陨石并不是形成行星的'代表性物质——它们只是行星形成过程中的副产品而已。也就是说，它们只是“做”行星的“辅助调料”而非“主要食材”。这项发现也许会极大地改变人们对太阳系的认识。

　　虽然如此，但陨星对于研究太阳系的形成过程而言仍是一条重要线索，具有十分重要的意义。

　　说到陨星，人们的第一印象便是“要掉落在地球上的星星”，它“划破夜空”，拖着长尾，浅意义上可以理解为“还未落到地面上的大流星”。那么它与同样有长尾的彗星有何区别呢?首先，两者的运行状况不同。陨星是“来自太空冲入地球大气层的大流星体”，本质上来讲它是宇宙中的天体在接近地球时受地球引力吸引而脱离其原有轨道冲入大气层的较大流星体，而彗星则是围绕太阳周期性运转的独立星体。第二，两者“尾巴”的形成原因不同。我们看到的“划破夜空”的星星之所以有条长长的尾巴，是它在冲入地球时与大气层摩擦发热所致，而彗星的尾巴源自彗星物质蒸发，当它接近太阳时，在其冰核周围便会出现朦胧的慧发和一条彗尾。
