Cloning is the process of making an exact copy of a plant or animal and developing it either naturally or artificially. The first successfully cloned animal was a sheep【小题1】(name) Dolly in 1996. In January 2018, the two cloned long-tailed monkeys【小题2】(announce) by Chinese scientists. They were the first-ever primates, 【小题3】proved to be much harder. The success has led to worldwide praise as a huge breakthrough.

At the basic level, 【小题1】intelligence is a branch of computer science that aims to create intelligent machines. One of the 【小题2】aims of AI is to develop computer intelligence capable of learning from experience, adjusting to new 【小题3】and performing tasks like humans. To achieve this aim, many approaches to creating true AI have been put forward, including “deep learning”, which enables a machine to improve its own performance by learning from the results of its previous actions. Deep-learning AI has the capacity to 【小题4】massive amounts of data through multiple layers, imitating the complex 【小题5】of the human brain.

China’s space programme started later than those of Russia and the US, but it has made great 【小题1】 in a short time. China became the third country in the world to 【小题2】 send humans into space in 2003, when Yang Liwei successfully 【小题3】 Earth in the Shenzhou 5 spacecraft. Then Shenzhou 6 and 7 completed 【小题4】 second manned orbit and the first Chinese spacewalk, 【小题5】 by the vehicle Jade Rabbit being sent to the moon to study its surface. After that, China 【小题6】 the Tiangong 2 space lab into space and Tianzhou1 to dock 【小题7】 it. This 【小题8】 one step further in China’s plan to 【小题9】 a space station in the future. More recently, China has sent Chang’e 4 to explore the surface of the far side of the moon to make 【小题10】 and observations.
