Turns out，you're not just what you eat—you're also where you eat．

  Researchers found out that people had double the number of calories(卡路里)when standing in a messy kitchen compared to when they stood in an orderly one．

    The researchers had 98 women spend to minutes in kitchens，under the guise of (以……为幌子)asking them to wait for someone．Half of the women stood in a messy kitchen，with piles of newspapers，dirty dishes and a ringing phone．The other half of the women waited in a clean kitchen．

    Both kitchens had bowls of biscuits and carrots．Each woman in the messy kitchen ate twice as many cookies compared to those in the clean kitchen．

    Why did this happen?

    “Being in a messy environment and feeling out of control is bad for diets，''Lenny Vartanian，one of the researchers，said．“It seems to lead people to think，‘Everything else is out of control,so why shouldn't I be?'''

    The study's size was small，but the findings prove something we know all too well：Stress(压力)is bad for you．Stress often causes people to overeat．Beyond weight gain，too much stress can also increase a person's heart rate，and lead to painful conditions like headaches．

    While there are many ways to manage stress．including listening to music and exercising，this study shows that there are easy and quick things you can do to find calm．The next time you don't want to tidy up the kitchen，remember that the exercise will help you a lot in so many ways．

    Today many people like growing plants at home because the plants help make the indoor environment beautiful and healthy. However, sometimes people may be too busy to remember to water their plants. If you have the same problem, don't worry. Designer Alastair Crompton can help you solve the problem with his amazing product-Plant Pod. It can water itself without any help.

    The Plant Pod is a self-watering container (容器) for small to medium-sized plants inside the house. Alastair Crompton makes it use a very simple process to provide the plant with the water it needs every day. With a Plant Pod, people no longer need to worry about how much water is perfect for their plants to grow. The water in the Plant Pod is enough to last for at least two weeks. So if people are away from home on a short holiday, they don't need to ask their relatives or neighbours to look after their plants. Won't it be great to see your plants welcome you when you are back home after one or two weeks?

    Do you know kind words and light music can help plants grow better? Many people talk and play music to their plants. And many people try very hard to protect their plants from loud noise, strong light and bad smell. That's not all. Some people are very careful about what they say or do in front of plants. They don't talk about unhappy things and won't beat a fly near their plants.

    Do plants have feelings? Many pupils think so. Even a few scientists think that plants have feelings. But most scientists don't agree. They don't think that plants call be happy, worried, angry, loving or afraid. They don't believe that a plant's feeling can be hurt.

    Professor Cleve Backster in America did an experiment and said that plants have feelings like human beings. He published an article in a magazine in 1968. People began to pay more attention to this topic since then.

    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.
