The best-known (最熟知的) vegetable in the world is the potato. It grows in many places and does not need rich soil(土壤) like many other crops. But until four hundred years ago, the Europeans(欧洲人) began to know the potato. But today it's one of the main foods in Europe(欧洲). About half of the world's potatoes are grown in Europe.

    In France the potato was not grown for a long time .Here is story about Louis. In 1778 he saw some potato flowers for the first time .He liked them so much that he picked one and put it in his buttonhole. He was interested in the flowers not the potatoes themselves.

    What do you think the future will be like? Here are some answers from some students.

    Mary: Everyone will have a computer at home. There will also be many machines in the future. Then people will work only two or three days in a week.

    Jack: The weather in the future will be very hot. People can't live on the earth. They will have to look for (寻找) another planet to live on.

    Linda: I think the life in the future will be nice. There will be a lot of flowers and trees. And cities will look like parks.

    Henry: Every family will have a family doctor, so people will be seldom ill (很少生病) They will live to 120 years old.

    A about 6.0-magnitude(震级) earthquake(地震) hit Yi'bin, Sichuan at 22:55 on June 17th, 2019,and it killed at least 12 people and injured(受伤的) more than 220.

    Many people in Chongqing felt it. Most of them rushed out to the safe places such as the square, the playground, the street .But some didn't.

    What can we do when an earthquake happens? In fact, there's little we can do to stop natural disasters(自然灾害) such as earthquakes happening. But, some methods can reduce(减少) the harm they cause.

    Drop down onto your hands and knees. This way can protect you from falling.

    Cover your head under a strong table or desk. You can also stay along a wall, and cover your head with your arms and hands.

    Hold on to(守住，抓牢) your shelter(遮蔽物) until the shaking stops. Be prepared to move with your shelter if the shaking continues.

Schools can normally take the earthquake drills(演练) to help student stay alive.

    I used to shower with soap every day, but my skin(皮肤)always felt dry and itchy(发痒的). Then two months ago, I heard of the no-soap movement. Since then, I've given up using soap in the shower. I still shower every day. I just don't use soap because it's filled with chemicals.

    So, what's so bad about using soap? Well, the chemicals in soaps can be harmful to our health. So, if we use soap, our skin will take in the chemicals, which will then end up in our bodies. According to the scientists, some of the chemicals used in a soap are quite dangerous. During my research, I also learnt that soap removes moisture(水分)from the body. This is actually why my skin was so dry and itchy.

    Getting used to washing my body without soap was a huge change. For the first week, I felt a bit dirty and I didn't smell great, either. However, during the second week, my skin felt clean without strange smell. Best of all, my skin problems disappeared, and now I have softer and healthier skin.

    On the whole, going soap-free has not only saved me time and money, but has also improved my skin. What's more, this experience has made me take a look at some of the other products I use in the shower, such as shampoo. More about that in my next blog!
