Ⅴ.阅读理解
Do you know what the world looked like millions of years ago Although it's impossible to travel back in time, we can still get some information from fossils(化石).　
An international research team led by Chinese scientists has found some fossils in Zhangpu County in Fujian Province. They call the group the Zhangpu Biota(生物群).The biota includes around 25,000 amber(琥珀) fossils and 5,000 plant fossils. They are nearly 15 million years old! “The amber fossils have kept the ancient insects quite well, making it a natural ‘museum’ of old life,” a researcher said.
Scientists first found the Zhangpu biota in 2010. They kept doing research there and made several big discoveries(发现). According to scientific researchers, there was a strong warming event between 17 million and 14 million years ago. At that time, the carbon dioxide(二氧化碳) in the air was higher than the general level, and the common temperature was 3-7℃ higher than today, which may be very similar to the environment in 2100. Therefore, understanding the changing process of climate and biota during that period is meaningful to predict the future.
Scientists have found more than 200 families of insects, including bees and ants. The research shows that the Zhangpu Amber Biota is one of the world's four largest amber biotas. This study aims to understand the change of modern Asian tropical rainforest ecosystems(热带雨林生态系统) and how it provides information for future climate warming.
21.What does the underlined word “They” in the second paragraph refer to
A.Scientists. B.Fossils.
C.Plants. D.Amber.
22.Why do we call the Zhangpu biota a natural “museum”
A.Because it has about 25,000 amber fossils.
B.Because it has about 5,000 plant fossils.
C.Because the amber fossils show us the ancient insects clearly.
D.Because it is one of the world's four largest amber biotas.
23.According to the passage, how long have scientists studied the Zhangpu biota
A.For hundreds of years. B.For about 50 years.
C.For more than 100 years. D.For only about 10 years.
24.What can we know from Paragraph 3
A.There were 5,000 kinds of plants in Zhangpu.
B.The fossilized plants once lived in a tropical rainforest.
C.The temperature in the future may be higher.
D.The insects found in the fossils are no longer seen today.
25.This passage is written to 　　　　.
A.help readers learn about the Zhangpu biota　
B.show how the earth's environment changed　
C.ask readers to protect animals and plants
D.introduce a natural history museum to readers

Ⅴ.[主旨大意] 古生物学者在我国福建发现一处约1500万年前的化石宝库——漳浦生物群。这一生物群中保存着大量琥珀和植物化石标本,生动展现了远古生物在热带雨林中的生活图景,也为研究气候的变化提供了参考。
21.B　代词指代题。由画线单词的上一句“The biota includes around 25,000 amber fossils and 5,000 plant fossils.”可知, they代指fossils。
22.C　细节理解题。由第二段最后一句中的“The amber fossils have kept the ancient insects quite well, making it a natural ‘museum’ of old life”可知,这些琥珀化石使这些古代的昆虫保存完好,因此选C。
23.D　数字计算题。由第三段第一句“Scientists first found the Zhangpu biota in 2010.”可知,科学家2010年首次发现漳浦生物群,由此可计算出,科学家研究漳浦生物群只有约10年的时间,因此选D。
24.C　推理判断题。由第三段倒数第二句“…and the common temperature was 3-7℃ higher than today, which may be very similar to the environment in 2100.”可知,在2100年,气温可能会升高3-7℃。由此可推断,未来的气温可能会升高。因此选C。
25.A　主旨大意题。本文主要介绍了古生物学者在我国福建发现约1500万年前的生物群——漳浦生物群。A。
