16、 dream for writing Constant worry and tension can cause one to suffer hair loss. It would make sense that if it can cause this problem, perhaps it also may contribute to graying. However, there is no sound evidence to support this. Main factors in gray hair were thought to be age, stress, environmen

17、t and improper diet.In addition, genetics is a very powerful factor, if one of your parents turns gray at an early age, there is a good chance that you will too. The team led by Professor Andres Ruiz-Linares at University College London analyzed DNA samples of more than 6,000 volunteers in Brazil, C

18、olombia, Chile, Mexico and Peru. It identified a gene called IRF4 that is responsible for gray hair. He said the most important reasons for gray hair are genes rather than other influences. This newfound gene means that preventing or even reversing gray hair is now a possibility.But most scientists

19、think that the answer for gray hair comes from the cells in your hair. These are what determine the color and, eventually, the fade to grey. Your hair is made up of cells called melanocytes which produce pigments (色素) as they grow into the hair fiber. Our hair color is determined by the amount of me

20、lanin (黑色素) in our body. The more melanin a person has, the darker his or her hair color.There are two different types of melanins: eumelanins (真黑色素) and pheomelanins (类黑色素).The former produces black and brown pigments, while the latter produces red and yellow pigments. The exact amount of these pig

21、ments determines whether a person has black, brown, blonde or yellow hair. As we age, the ability of the melanocytes to produce more pigments weakens.Scientists are continuing to try and find ways to prevent graying hair. A team of scientists in France is working to try and stop the melanocytes from

22、 being damaged at the end of each hair cycle. They are trying to use a special enzyme to protect the cells from damage. If successful, it could lead the way for new products that keep our locks full of color for years to come.8What might play the most important role in the graying process according

23、to Andres Ruiz-Linares?A.genetics of human beingsB.constant worry and tensionC.the amount of food people eat and living environmentD.the amount of pigment9What do we know about yellow hair?A.It will turn black as people get older.B.The amount of pigments in it doesnt change over time.C.It contains m

24、ore pheomelanins than eumelanins.D.People with yellow hair have weaker ability to produce pigments.10What do the scientists from France aim to do?A.To repair damaged hairs.B.To shorten the hair cycle.C.To protect hair cells against damage.D.To study the relationship between health and hair color.11W

25、hat does the underlined word “locks” in the last paragraph probably refer to?A.melanocytes B.hairsC.cells D.pigments Artificial intelligence is set to benefit mankind in many ways. It will make everyday tasks easier and bring efficiency to various industries. It might just prove to be one of mans gr

26、eatest inventions. And yet, like any other technology, AI will also bring risks and dangers. When people mention that AI could be dangerous, most people think of scenarios from movies or books where an AI program decides to eliminate or conquer all humans.In February 2018, a group of AI experts got

27、together to discuss the potential misuse of AI. Their main concern was that criminals could use AI for a variety of evil purposes. Someone can use AI to create websites that could be used to steal peoples personal information. Another potential risk is faster hackingAI programs could be taught to fi

28、nd loopholes in software and break into secure computer systems. Some of the risks were as dramatic as the ones we see in books and movies. For example, the experts mentioned automated terrorism (自动化的恐怖主义) by using drones or unmanned vehicles as weapons. Remote attacks using such devices could be ma

29、de easier through the use of AI.And finally, there were some concerns on the fact that AI can mimic voices as well. Last year US filmmaker Jordan Peele teamed up with BuzzFeed website to make a movie using AI techniques to copy former US president Barack Obamas voice. They “had” him voice his opinio

30、ns on the 2017 movie Black Panther and current US President Donald Trump. While in China, tech giant Baidu, has also developed a program called Deep Voice that can “copy” anyones voice by analyzing a 3.7-second audio sample.Famous British physicist Stephen Hawking even thought AI could be the worst

31、event in the history of our civilization. “Once humans develop artificial intelligence, it will take off and redesign itself at an alarming rate. Humans couldnt compete and would be superseded, he told the BBCHowever, Hawking suggested “I believe we can create AI for the good of the world. We simply

32、 need to be aware of the dangers, identify them, employ the best possible practice and management, and prepare for its consequences well in advance.”Actually, AI technology is making great progress in terms of the three-stage development of artificial intelligence. It is unlikely that fully developing AI would make it hard for mankind to survive. After all, without human intelligence, AI cannot even develop itself, let alone rep
