五、(2025·盐城市阜宁县模拟改编)完形填空。〔人与自然——宇宙探索〕
Mars is the fourth planet from the Sun and the seventh largest among the eight planets of the solar system (太阳系). It is 1 than the Earth with a diameter (直径) of about 6, 779 kilometres. If you stand on Mars and 2 the Sun, it will appear about two-thirds of the size as we see it on the Earth. Mars is widely known as the 3 planet. Its red appearance is caused by the iron oxide(氧化铁) in the 4.
In many ways, Mars can be considered as the Earth's 5. On Mars' surface, we have discovered the 6 mountain in the solar system. It is named Olympus Mons, and its 7 is about three times that of Mount Qomolangma. A 8 on Mars is also a little longer than a day on the Earth. It lasts about 24. 6 9. A year on Mars, however, or the time that takes for the red planet to 10 the Sun, lasts about 687 Earth days. That is almost 11 as long as a year on the Earth!
In the 19th century, it was believed that 12 existed on Mars. An astronomer(天文学家) said that he “found” straight lines on 13 surface. Many people believed that 14 were the work of smart life as the straight lines were most likely to be irrigation canals(灌溉渠). However, as more advanced telescopes were 15, it was found that the straight lines were an optical illusion(视错觉).
To this day, humans are still trying to find out whether life exists on Mars.
