    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.

   Nowadays, computer games are becoming more and more popular in many cities and towns.
   A lot of small shops along busy streets have been made into small game houses in order to get more money. These places are always crowded with people, especially young boys.
   In the computer game houses, people spend a lot of money competing（较量） with the machines. It's hard for one to win the computer, but one can make progress after trying again and again. People have a kind of gambling psychology（赌博心理）when they play computer games. The more they lose, the more they want to win. When class is over, the school boys run to the nearby computer game houses. Little by little（渐渐地）, they forget all about their lessons and fall far behind others. Some of them can get enough money from their parents. But some of them are not lucky enough to get the money. They begin to take away other students' money and become thieves.

   Arctic fox(北极狐) is a kind of small fox that lives in the Arctic. It grows about 50 centimeters long, not including its tail, 30 centimeters tall and weighs from 3 to 7 kilos.
   The Arctic foxes are white or blue in color. The white ones are white in winter, but grey-brown in summer. The blue ones are blue-grey all year round. The Arctic foxes have long, thick hair that is called fur. And the long fur covers their whole bodies, including both their cat eyes and rabbit feet, to keep them warm in the low temperature in the Arctic.
   The Arctic foxes feed mainly on birds, birds' eggs and other small animals. Teamwork is the way they look for food, and they don't like to do that alone.
   Baby Arctic foxes are very lovely. They don't open their eyes until a week after their birth. For the first half of the year, their parents offer them food. They begin to look for food on their own when they are about six months old. The next year they can live alone.
   Today, the number of the Arctic foxes is becoming smaller and smaller, because people kill them for their fur to make beautiful coats for money. Something must be done to protect the Arctic foxes.

Why is clean water so important to developing countries? A recent report shows that about 80 percent of diseases in developing countries are caused by poor water and low sanitation（卫生）conditions. In those countries, women and girls spend several hours collecting water, but often polluted, far away from their families. The polluted water more or less influences their health. In this case, there is an urgent（迫切的）need for people in developing countries to have access to（有机会或权利使用）clean water to improve their health.

Here is a short story about Hadjara Zakari, a 12-year-old girl in Niger. Having access to clean water changed her life. She learned about the importance of hand-washing when the school first received clean water three years ago. That evening, she told her father, "You shouldn't eat with me unless you clean your hands." Her father was very angry and shouted at her, "It's not up to you to tell me what to do!"Stunned（目瞪口呆的），Hadjara sat in silence. But she knew she was right. In protest,Hadjara refused to eat dinner that night. After her father questioned Hadjara's head teacher, he understood the importance of hand-washing and his daughter's intentions（目的）. The girl really wanted her family to live longer and healthier lives.

For people in developing countries, clean water can change many things, especially improve their health. So, from now on, let's avoid wasting water and take action to save water, which is important to people all over the world.

We all waste food, you and me, every day, millions of tons of it. In China, enough food is wasted in restaurants every year to feed 200 million people. And the amount of food wasted by Chinese consumers is increasing fast. So our nation is being encouraged to stop wasting food.

So what should Chinese consumers do to prevent food waste?

♦ Keep a kitchen diary

All of us should keep a kitchen diary, and we can know that how much food we waste at home. The first thing for us to do is to stop throwing away food that we can still eat. We should eat everything we buy and if we cannot, we should buy less.

♦ Buy only what we need

We should ask for smaller portions in stores. We should also check how much food we have before buying more. We shouldn't bring much food we don't need home even if large posters ask us to do so.

♦ Develop the habit of packing food

Chinese consumers are generous and friendly. In restaurants, often too much food is ordered and served. So when ordering out, we are supposed to exclude the food in the order if we don't plan to eat it. And order smaller servings in restaurants and take home what we cannot finish.

Don't put it off! Let's stop food waste today!

阅读下面材料，从每题所给的A、B、C、D 四个选项中选出最佳选项。

OpenAI has shocked the world with its latest creation, Sora. The AI tool can produce videos up to one minute long. Many people worry that the tool will put many filmmakers out of business.

Similar worries have been voiced since the appearance of the AI chatbot ChatGPT and text-to-image programs like Dall E. Many are afraid that industries (行业) such as programming, translation, teaching and design will all disappear. It seems we can turn to AI for just about anything we want to do.

Does that mean we no longer need to gain knowledge and skills ourselves? Well, the answer is "No". Even in the age of AI, knowledge is still powerful. In fact, it may ask you to use your brain more. AI is knowledgeable, but for now, it needs instructions (指令). In other words, you must communicate with it. For example, you want advice on how to get a better return on your savings. If you don't know anything about finances (经济), you'll have trouble asking the right questions.

You also need to exercise your imagination more actively. Take the Chinese New Year celebration video for example. You need to be clear about your expectations and use your language skills to describe them in as much detail as possible. Where is the celebration taking place? What performances are going on? What are the performers wearing? You may also need to be a bit professional (专业的). For example, "Throw in a close-up of a dragon dancer."

And keep in mind that AI can make mistakes. After AI gives you an answer, you need to judge (判断) whether all the information is correct and up to date. To do this, you need at least some basic knowledge about the related (相关的) subjects.

If you think the development of AI has given you the right to be lazy, it's time to stop day dreaming. Work harder on your studies so that you'll be able to work with AI.
