    A 15-year-old student who invented a flashlight(手电筒) getting power from the holder's body heat is going home today from California with a big prize and a chance to do further research.
    Ann Makosinski was the only Canadian among the four winners at Google's international science competition. Thousands of young scientists from around the world took part in the competition.
    Winning the science and technology competition was "a surprise". Ann said, "I think it will have a great influence on my future."
Ann thanked her family for encouraging her interest in science and said that her first toy was a box of transistors(晶体管).
Ann's prize includes $ 25,000 and a "once in a-lifetime expericnce" from Google for her Hollow Flashlight, which has no moving parts or batteries.
    The idea for the invention came from seeing unwanted batteries and her friend's experience. When Ann visited a friend in the Philippines, she saw the friend couldn't study when it became dark because there was no electricity or light. She saw the need for a flashlight that has no batteries - Hollow Flashlight.
    In her project, Ann wrote "I made two flashlights that do not use any batteries or harmful materials. They do not create any noise and will always work. The flashlight needs at least a 5℃ temperature difference between the holder's body and the environment around to produce light."
    A video of Ann explaining how she creatcd the flashlight has been watched more than 1.4 million times on the Internet.
Though Ann was successful, she has not made a decision about her career path. Ann hopes that she can find a way to join her love of film and science together.
    The four winners were chosen from 15 final competitors from eight countries. The competition attracted thousands of students in 120 countries.

    Artificial intelligence(AI)(人工智能)is the ability of a computer program or a machine. The computer or the machine with AI can think and learn. It is also a field of study that tries to make computers "smart". John McCarthy, a scientist, came up with(提出)the name "artificial intelligence" over 60 years ago. Many things such as learning and problem solving can be done by computers, though not in the same way as people do.

    An unusual goal of AI research is to create computer programs. They can learn, solve problems, and think logically(逻辑地). At present, Al can successfully understanding human speech, recognizie (识别)human faces, operate self-driving cars and compete in some game systems like playing Chess. However, Some people also consider(认为)AI a danger to humans if it develops too quickly. A famous British scientist also was not for this kind of technology.

    Math is the basic language of AI. If students are good at math, they will be more likely to become successful AI designers(设计者)in the future. We need not only bright students, but also average(普通的)students. As for(对于)average students ,if they get enough math skills, they can also become successful AI designers. Besides, a good knowledge of computer science is also necessary for AI designing.

    Scientists hope to create creative(有创造力)and emotional (有感情的)AI. The AI can possibly understand human feelings or create art. Many ways and tools have been tried to discover this wide and exciting field.

 Visiting museums can be interesting but tiring. You may spend hours getting there, waiting in a long line for a ticket, and walking with big crowds in the museum. But new kinds of technologies are changing museums and the way people visit them all over the world.

 Thanks to the Google Art Project, you may"walk through" museums while staying at home and enjoying an icy milk shake. It uses Google's Street View technology. You can see how paintings are hung and exhibits(陈列品) are placed as you move virtually (虚拟地) through the museums. You can also read the introductions of the works and download(下载) clear pictures of them. So far 560 museums around the world have joined the project, such as the British Museum in London and the Metropolitan Museum of Art in New York City.

 Some apps may also make your museum trips more fun. The Palace Museum designed a few apps. One is called Han Xizai's Night Feast. Users can see a big picture of Han's house and take a closer look at the people and the clothes within it by touching the screen. The Museum of Modern Art in New York City also made an app that allows users to draw their own modern art works.

 However, if you still want to visit museums in person, you probably won't be disappointed. Many museums are trying to allow visitors to interact(互动) with the exhibits using 3-D technology. The exhibition in Shenzhen shows a 3-D copy of ancient Chinese bronze chimes(青铜编钟). Visitors can"play" the chimes by simply touching them.

 With new technologies like this, visiting museums has become easier and more fun. So why not try it yourself?

 阅读下列短文,从下面每小题的 A、B、C、D四个选项中选出最佳选项。

 We all have experienced the strong link between smell and memory. A whiff of chlorine(一股氯气) probably reminds you of summer pool parties, while the scent of flowers may bring back memories of your grandma's garden. Now, researchers from the University of California, Irvine (UCI) have found that breathing in pleasant smell could even help improve memory and learning.

 The study, led by Cynthia Woo, invited 43 healthy adults aged between 60 and 85. The scientists divided them into two groups. The test group(实验组) was provided with some natural oils with different fragrances(芳香). They included orange, eucalyptus(桉树), lemon, peppermint(薄荷), rosemary(迷迭香), and lavender(熏衣草). However, the control group(对照组) only received fewer types of natural oils with different fragrances.

 The participants were asked to use one of the scented oils(香精油) to perfume(使...充满香味) their homes for two hours every night for six months. They were also asked to change the fragrances every night.

 At the end of the six months, all volunteers took a memory test. The test group outperformed the control group by a shocking 226 percent!

 Woo and her team thought that it does not matter when the scents are taken in. However, varying the fragrances is the key. The scientists believe the changes of different smells helps activate (激活) the memory centers of human brains.

A new study has found that certain fragrances may help prevent memory loss in adults. The findings were published in   the journal Frontiers in Neuroscience on July 24,2023. The study also showed that certain fragances could probably also help improve memory in younger people.

 The UCI team's next plans are to carry out a similar study on older people who already suffering from memory loss. They are eager to learn if pleasant smells can help reverse(逆转) the memory loss.
