①China published the world’s first highly clear lunar geologic (地质的) atlas (地图集) on April 21. According to the Chinese Academy of Sciences (CAS), it will provide up-to-date information for future lunar research and exploration.

②“These maps will help choose locations for future lunar research stations,” Ouyang Ziyuan, a well-known lunar scientist, said. “They can also help us better know about the Earth and other planets in the solar system, like Mars.”

③The world has seen great progress in the field of lunar science over the past half a century. However, the lunar geologic atlas that was developed during the Apollo Program remained unchanged. “As lunar geologic studies develop, those old maps can no longer satisfy future needs,” said Liu Jianzhong, a CAS researcher.

④Since 2012, Ouyang and Liu have led a team of scientists from several research centers in compiling (编制) this atlas. Their work was mainly built on information gained from China’s Chang’e Program. Information from other research projects and international tasks was also used.

⑤The new geologic atlas, which is published in both Chinese and English, presents a scale (比例尺) of 1: 2.5 million. Compared with the 1:5 million scale lunar maps from the US in 2020, these larger scale maps show more details. As well as the geologic history of the moon, they provide information on its 14 types of structures (结构) and 17 types of rocks. A total of 12,341 impact craters (撞击坑) and 81 impact basins have also been marked.

⑥This atlas is set to serve many useful purposes, such as lunar resources research and science education. Liu said the upcoming Chang’e-6 task would also use the atlas. “Our maps can help the research by providing scientific support,” he explained.

⑦“Compiling the atlas was a huge task, which included years of effort from a large number of researchers,” said Gregory Michael, a German scientist. “It will be a starting point for every new question of lunar geology.”

1.What is the great value of the new atlas?

A It is the first lunar geologic atlas in the world.

B It proves the hard work of Chinese scientists.

C It will meet the future needs in lunar studies.

D It is built on information from many researches.

解析：选C。C. 推理判断题. 由However, the lunar geologic atlas that was developed during the Apollo Program remained unchanged. “As lunar geologic studies develop, those old maps can no longer satisfy future needs,”可知旧的月球地质图集已经不能满足未来的需求，而新的图集将能满足未来的需求，所以选C。

2.What is Paragraph 5 mainly about?

A The large size and mystery of the moon.

B The discovery of Chang’e Program.

C The details of the new geologic atlas.

D The challenges the scientists face.

解析：选C。C. 段落大意题. 根据第五段“Compared with the 1:5 million scale lunar maps from the US in 2020, these larger scale maps show more details.”可知第五段主要介绍了新的地质图集的详细信息，所以选C。

3.How does the writer prove “This atlas is set to serve many useful purposes”?

A By comparing different purposes.

B By using Chang’e-6 task as an example.

C By using a German scientist’s words.

D By listing information from the new maps.

解析：选B。B. 推理判断题，根据“Liu said the upcoming Chang’e-6 task would also use the atlas. “Our maps can help the research by providing scientific support,” he explained.”作者通过使用嫦娥六号任务作为例子来证明“这个图集将有很多的用处”，所以选B。

4.What does “It” in the last paragraph refer to(指代)?

A Scientific support.

B The lunar research.

C Effort from researchers.

D Compiling the atlas.

解析：选D。D. 词义指代题，由最后一段可知，it指代的是compiling the atlas，所以选D。
