以下是一個關(guān)于“系外行星學”主題的英語六級閱讀練習示例，旨在幫助學習者在掌握知識的同時，進一步加深對英語運用的理解和感受。

英文原文

In recent years, the field of astronomy has witnessed a remarkable revolution, thanks to the advancements in technology. Telescopes have become more powerful, allowing astronomers to observe objects in space that were previously beyond reach. With these improvements, a new area of study has emerged, known as exoplanetology, which focuses on the exploration of planets outside our solar system.

近年來，由于技術(shù)的進步，天文學領(lǐng)域經(jīng)歷了顯著的變革。望遠鏡變得更加強大，使天文學家能夠觀測到以前無法觸及的太空物體。隨著這些改進，出現(xiàn)了一個新的研究領(lǐng)域——系外行星學，它專注于探索我們太陽系之外的行星。

Exoplanets are planets that orbit stars other than our Sun. These planets range in size, from dwarf planets similar to our Moon to gas giants larger than Jupiter. The discovery of exoplanets has challenged many existing theories about the formation of solar systems and the potential for life beyond Earth.

系外行星是圍繞除太陽以外的恒星運行的行星。這些行星的大小各不相同，從類似我們月球的矮行星到比木星還大的氣體巨星。系外行星的發(fā)現(xiàn)挑戰(zhàn)了許多關(guān)于太陽系形成以及地球以外生命潛力的現(xiàn)有理論。

One of the most significant challenges in exoplanetology is the detection of these planets. Since they are so far away, their light is often overwhelmed by the brightness of their host stars. However, scientists have developed several techniques to overcome this obstacle, including the transit method, which involves observing the dimming of a star as an exoplanet passes in front of it.

系外行星學面臨的一個最大挑戰(zhàn)是檢測這些行星。由于它們距離我們?nèi)绱诉b遠，它們的光常常被它們的主恒星的光所淹沒。然而，科學家們已經(jīng)開發(fā)了幾種技術(shù)來克服這一障礙，包括凌日法，該方法涉及觀察一顆恒星在其前面的系外行星經(jīng)過時變暗的情況。

In addition to detection, another crucial aspect of exoplanetology is characterizing these planets. This involves determining their mass, density, and atmosphere, which can provide clues about their potential for habitability. For example, the presence of water vapor in an exoplanet's atmosphere is a strong indicator of its ability to support life.

除了檢測之外，系外行星學的另一個關(guān)鍵方面是描述這些行星的特性。這包括確定它們的質(zhì)量、密度和大氣層，這些都可以為它們的宜居潛力提供線索。例如，系外行星大氣層中存在水蒸氣是其支持生命能力的有力指標。

問題

1.What is exoplanetology focused on?
A. The study of stars.
B. The exploration of planets outside our solar system.
C. The formation of solar systems.
D. The potential for life on Earth.

2.What are the two main challenges in exoplanetology?
A. Detection and characterization of exoplanets.
B. The brightness of host stars.
C. The size of exoplanets.
D. The formation of solar systems.

3.What technique is mentioned in the passage for detecting exoplanets?
A. The transit method.
B. The gravitational lensing method.
C. The radial velocity method.
D. The direct imaging method.

答案解析

1.答案： B

解析： 根據(jù)段落一中的描述，“With these improvements, a new area of study has emerged, known as exoplanetology, which focuses on the exploration of planets outside our solar system.”（隨著這些改進，出現(xiàn)了一個新的研究領(lǐng)域——系外行星學，它專注于探索我們太陽系之外的行星。）因此，系外行星學關(guān)注的是太陽系之外的行星的探索，選項B正確。

2.答案： A

解析： 段落三提到系外行星學面臨的一個最大挑戰(zhàn)是檢測這些行星，而段落四提到另一個關(guān)鍵方面是描述這些行星的特性。因此，系外行星學的兩個主要挑戰(zhàn)是檢測和描述系外行星，選項A正確。

3.答案： A

解析： 段落三提到科學家們已經(jīng)開發(fā)了幾種技術(shù)來克服檢測系外行星的障礙，其中包括凌日法（the transit method），該方法涉及觀察一顆恒星在其前面的系外行星經(jīng)過時變暗的情況。因此，選項A正確。
