I believe that human【小题1】is wrong. If we【小题2】with nature, we will have to deal with the【小题3】. Who knows【小题4】could happen? Human life would just become a crop to be【小题5】or a project for sale. The human race is【小题6】up the Earth’s natural wealth. We should be having fewer babies in order to【小题7】the Earth’s population, not cloning more. I feel sorry for the lady【小题8】cannot have a baby, but I would like to【小题9】out that there are many children in the world with no parents who would be【小题10】to have a mother.

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.

Genes play a critical role in overall health. Every cell in the human body contains genetic information. Everything from the ageing process to the development of 【小题1】, such as cancer, is tied to an individual’s genetic make-up. However, scientists have long been 【小题2】 the question about which genetic markers indicate a short or long lifespan. The discovery by the research team may 【小题3】 of the study on genes and human lifespans, and eventually help answer this question.

Scientists say that locating these sixteen genetic markers will greatly improve their understanding of how genes affect lifespans. These genetic markers may eventually 【小题4】 a means of targeting the specific genes connected with lifespans. This could significantly enhance people’s chances of living to a ripe old age. According to some scientists, it could make 【小题5】 to the future of human life.

At the basic level, artificial intelligence is a branch of computer science that aims to create intelligent machines. One of 【小题6】 of AI is to develop computer intelligence 【小题7】 learning from experience, 【小题8】 new inputs 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 【小题9】. Deep-learning AI 【小题10】 to analyse massive amounts of data through multiple layers, imitating the complex networks of the human brain.
