1 Chinese scientists have for the first timediscovered a new mineral on the moon，making? China the third country to dis?cover a new mineral on the moon.

2 Changesite?（Y） is a chemical mineral incolumnar crystal （晶體） found in lunarbasalt（玄武巖）particles. Scientists fromBeijing Research Institute of UraniumGeology isolated a single crystal particlewith a radius （半徑） of about 10 microns through high?tech means such as X?ray fromthe 140，000 lunar sample particles， and interpreted its crystal structure.

3 The Commission on New Minerals， Nomenclature and Classification （CNMNC） of? theInternational Mineralogical Association （IMA） confirmed it as a new mineral. It is thesixth new mineral discovered by humanity on the moon， and China becomes the thirdcountry in the world to discover a new mineral on the moon.

4 The name of the new mineral， Changesite?（Y）， is the combination of “Chang’e” and“site”， which is to pay tribute to the great achievement of China’s lunar explorationproject as it is often called Chang’e Project.

5 According to experts， the site where Chang’e?5 mission collected samples is about 1 bil?lion years younger than where some samples were previously collected. It is significantin understanding the origin and evolution of the moon. Chang’e?5 mission managed toget samples from the moon weighing about 1，731 grams in 2020， which were the firstlunar samples in the world in over 40 years.

6 Scientists from several departments including Chinese Academy of Sciences， Ministryof Education and Ministry of Natural Resources were involved in the research of themoon samples， and the achievements they have made so far are of great significance forunderstanding the origin and evolution of the moon and exploring the effective utiliza?tion of lunar resources.

Ⅰ. Difficult sentence in the text

The name of the new mineral， Changesite?（Y）， is the combination of “Chang’e” and“site”， which is to pay tribute to the great achievement of China’s lunar exploration projectas it is often called Chang’e Project. 這種新礦物“嫦娥石”的命名，是“嫦娥”和“居住地”兩個(gè)詞匯的結(jié)合，是為了紀(jì)念被稱為“嫦娥”的中國(guó)探月工程的偉大成就。

【點(diǎn)石成金】本句是一個(gè)復(fù)合句。The name of the new mineral， Changesite?（Y）， isthe combination of “Chang’e” and “site”是主句；which引導(dǎo)非限制性定語從句，該定語從句中含有一個(gè)由as引導(dǎo)的原因狀語從句。
