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.

Since the 1970s many new 【小题1】 have been found for me. I have become very important in communication, finance and trade. I have also been put into robots and used to make 【小题2】 phones as well as help with medical operations. Anyhow, my 【小题3】 is to provide humans with a life of high quality. I am now truly filled with happiness that I am a 【小题4】 friend and helper of the human race!

It shows the 【小题5】 of wildlife protection, but I’d like to help as the WWF suggests. The carpet rose again and almost at once they were in a thick rainforest. A monkey watched them as it 【小题6】 itself. ―What are you doing? asked Daisy. ―I’m 【小题7】 myself from mosquitoes, it replied. …You should pay more attention to the rainforest where I live and 【小题8】 how the animals live together. No rainforest, no animals, no drugs.

Sometimes they may play to 【小题9】 in the street or subway so that they can earn some 【小题10】 money for themselves or to pay for their instruments.

One characteristic of hybrids is that they usually a【小题1】 a higher yield than c【小题2】 crops. However, whether it was possible to develop a hybrid of self-pollinating plants such as rice was a matter of great d【小题3】. The common a【小题4】 then was that it could not be done. Through i【小题5】 effort, Yuan o【小题6】 enormous technical d【小题7】 to develop the first hybrid rice that could be used for f【小题8】 in 1974. This hybrid e【小题9】 farmers to e【小题10】 their output greatly.
