Task2
(1)Dr. Sun Qiang, director of the research team, said they had been wholly devoted to the research and had been taking care of more than 1,000 monkeys 24 hours a day, 7 days a week for more than 5 years.
研究小组的负责人孙强博士说，他们全身心地投入到研究中，5年多来每周7天，每天24小时照看1000多只猴子。
(2)The reason they worked so hard to break this technical barrier was to get animals with edited genes and produce animal models that are helpful for medical research and human health.
他们之所以如此努力地要突破这一技术壁垒，是为了获得经过基因编辑的动物，研制动物模型，为医学研究和人类健康发展做贡献。
(3)The successful cloning of primates has led to worldwide praise as a huge breakthrough that might lead to cures for various diseases and may also offer clues on how to prevent the aging process.
灵长类动物的成功克隆获得了全世界的赞誉，被认为是一项巨大的突破，从而为治愈多种疾病、延缓衰老提供线索。
In January 2018, the cloning of two long-tailed monkeys, Zhong Zhong and Hua Hua, was announced by Chinese scientists. They were the first-ever primates (the order of mammals which include apes, monkeys, and humans) to have been cloned! In comparison with other species, cloning primates has proved to be “much harder”, and doing so with non-reproductive cells was even more complicated.

Dr. Sun Qiang, director of the research team, said they had been wholly devoted to the research and had been taking care of more than 1,000 monkeys 24 hours a day, 7 days a week for more than 5 years. There had been a number of failures before they eventually found a way to successfully clone a monkey.

that引导的定语从句，代替先行词在从句中做主语
With this technology, we have the potential to raise a large number of monkeys with identical genes in a short amount of time, and we can even change their genes to suit research needs. This could help save research time, reduce the number of animals required for testing, produce more accurate results, and lead to more effective treatments.
