（原创）China's first cat cloned from somatic cells(体细胞) using only homegrown equipment（设备）and reagents was born in Qingdao, showing that the country has built an independent cloning process(自主克隆过程), according to researchers.
The cat, an orange male of 141 grams, was given birth to by a female(雌的) cat after a 69-day pregnancy. Researchers from Qingdao Agricultural University worked with Qingdao PanGene Technologies Company on the project.
Zhao Minghui, an associate professor at the university's College of Life Sciences, said that the past animal cloning processes had depended heavily on imports(进口) from the United States and equipment provided by Japan and Europe. “The birth of the new cat turned out that China has a complete industrial chain in the field of animal cloning,” Zhao said.
The research, which began in 2020, faced difficulties like imported reagents during pig cloning tries. Over time, the team successfully changed to homegrown reagents, with additional help from a partner in Guangzhou, to further improve their research equipment.
From the end of October to the beginning of November in 2023, the team succeeded in cloning 20 pigs of a local type using homegrown equipment and reagents. “Different from pig cells, cloning cats from somatic cells needed more equipment, reagents, and materials,” Zhao said. Yuan Bao, a professor at Jilin University and president of the Jilin Association for Laboratory Animal Sciences, said the success in cloning a cat was not only a big breakthrough in Chinese animal cloning technology, but also stood for improvement in high-end equipment producing, precision machining, and chemical engineering in China.
1. What's the main purpose(目的) of the passage?
A. To describe the difficulties of cat cloning.
B. To share the process of China's first cat cloning.
C. To show China's independent animal cloning technology.
D. To tell the differences between Chinese equipment and foreign equipment.
2. How might Zhao feel about the cat cloning?
A. Successful.
B. Meaningless.
C. Educational.
D. Impossible.
3. The underlined word “breakthrough” in Paragraph 5 means
A. a difficult finding
B. an important success
C. an act of finishing doing something
D. an opening between two things
4. What can we infer from the last two paragraphs?
A. Cloning cats from somatic cells is more difficult than cloning pigs.
B. The cat cloning showed improvement in high-end equipment producing.
C. The success of cloned cats means China will never need imported equipment.
D. The research on cloning pigs lasted for three years and succeeded within a month.

答案
训练2 【语篇解读】本文是一篇说明文。文章主要介绍了中国首只只使用国产设备和试剂的体细胞克隆猫在青岛诞生。
1. C 推理判断题。结合文章内容，尤其是第一段可知，本文主要介绍了中国首只只使用国产设备和试剂的体细胞克隆猫在青岛诞生，其目的是证明中国在动物克隆方面能够完全独立了。故选C。
2. A 推理判断题。根据第三段“The birth of the new cat turned out that China has a complete industrial chain in the field of animal cloning”可知他认为克隆猫的诞生证明了中国在动物克隆领域拥有完整的产业链，由此可推知他认为克隆猫技术是成功的。故选A。
3. B 词义猜测题。根据下文“but also stood for improvement in high-end equipment producing, precision machining, and chemical engineering in China”可知克隆猫的成功也代表了中国在高端设备制造、精密机械加工和化学工程方面的进步，由此可推知“breakthrough”代表了中国在动物克隆技术上的突破。画线词所在句与下文是并列关系。故选B。
＞＞ 逻辑关系
4. A 推理判断题。根据最后一段“the team succeeded in cloning 20 pigs of a local type using homegrown equipment and reagents. 'Different from pig cells, cloning cats from somatic cells needed more equipment, reagents, and materials'”可知中国已使用国产设备克隆过猪，但是克隆猫需要更多资源，由此可推知克隆猫的难度大于克隆猪。故选A。
