E-waste is fast becoming a serious problem around the world. This report will examine this problem and provide some possible ways to solve it.

We live in a society that is producing and using electronics(电子产品) all the time. It is often cheaper to buy new products than to repair old ones. Also, through clever advertising, companies always encourage people to change their old TVs, mobile phones and computers for the latest models. E-waste is created when we throw away old ones. In the EU alone, about 8,700,000 tons of e-waste is produced each year. Sadly, just over 1,000,000 tons is recycled.

    Burying(填埋) e-waste or burning it cause serious problems for the environment. Electronics have dangerous things in them. These things can then get into the ground or pollute the air when they are burnt.

    In recent years,   ▲  . However, their plans are not always managed properly. Sometimes electronics are just sent to poor countries such as Ghana. Here they are often burnt in public areas, which is very bad for people's health. Setting up recycling centers is a good way to solve this problem. E-cycling centers could recycle the parts that can be reused and deal with the rest properly.

    Another way is to make producers responsible(负责任) for their used products. This means that producers must take back old products which are no longer wanted. They should then make sure they are properly recycled or reused.

    As for us, we should try to cut down on e-waste. Change electronics only when we have to. And don't buy a product just to have the latest model.

    E-waste is a serious problem in the modern world. Both producers and users must take actions and try to keep it to the smallest amount.

    Have you heard about "Face Recognition (刷脸)" technology? It begins to become a popular and exciting development in China. In September 2017, a Kentucky Fried Chicken KPRO restaurant in Hangzhou utilized (利用) this new technology.

    Customers will go through the buffet (自助餐) line and then check out with their food using this "Just look with your face" payment method. When they get to the payment machine, they simply choose the Payment of facial recognition and then stand in front of the screen for 1-2 seconds. They then confirm their account and phone number and finish the payment process—all of it takes no more than 10 seconds!

    Nowadays, the words "Face Recognition" have become popular around China with the development of the ability to pay with facial recognition. Here are several examples of how you might hear the words in daily life in China. In Hangzhou, a high school provides a service where students can pay for meals by facial recognition. However, this isn't the only way we use the words in China! When you combine these characters together you also get another meaning: Jackie Chan got a dinner for free by "brushing his face".

    What should you do if there's an earthquake at school? How can you protect yourself when you are caught in a stampede(踩踏)?March 28, 2016 provided you with a good chance to learn about safety.

    This day was called the National Day of Education on the Safety of Elementary and Middle School Students(NDESEMSS)(全国中小学生安全教育日). The theme of the day was to give students more knowledge about safety and make sure their lives are safe.

    A survey done by the China Youth and Children Research Center showed that school accidents kill more elementary and middle school students than anything else. The main accidents come from stampedes, earthquakes, fires and sports injuries(伤害).

    What can we do to keep ourselves safe? Staying calm is the first and most important rule when facing accidents. But different accidents have different self-protection advice.

    A stampede is possible anywhere. The larger a crowd gets, the more likely stampedes become. When students around you begin to push, stand still and try to hold onto something, or stay in a corner until the crowd leaves. If you fall down in a moving crowd, cover your head with both hands. Lean to(偏向) one side, curl up(蜷缩) your body and bend your legs.

    Earthquakes are common natural disasters(灾难). When you feel the ground shake, drop down, take cover under a desk and hold on. You should stay indoors until the shaking stops. If you are outdoors, don't stay near buildings, trees or power lines.

    When there's a fire, follow the teachers' instructions, leave the classroom quickly and use a piece of wet cloth to cover your mouth and nose so that you don't breathe in smoke.

    Big ocean fish have almost been endangered since the start of business fishing in the 1950s. The scientists found that the number of large fish has dropped by 90 percent in the past fifty years. The study took ten years. The researchers collected records from fishing businesses and governments around the world. The magazine Nature published (发表) the findings.

    The scientists say the common way called long line(多钩长线) fishing is especially harmful to large fish. This way includes many fishing lines that are connected (连接) to one boat. If these lines are joined together, they can reach one hundred kilometers. They hold thousands of sharp metal hooks to catch fish. Long line fishing is especially common in the Japanese fishing industry. Records showed that Japanese boats used to catch about ten fish for every one hundred hooks. The study says long line fishing boats now might catch one fish per hundred hooks.

    The scientists say business fishing can destroy groups of fish much faster than in the past. The study suggests that large fish can disappear almost completely from new fishing areas within ten to fifteen years. Ocean life systems could be destroyed.

    It's not the only worry that the number of large fish is becoming smaller and smaller. What's worse, they are smaller in size than their ancestors (祖先).
