Battling e-waste
E-waste, the world’s largest and fastest growing type of waste, doesn’t only come from computers but other electronics as well. |
In 2019, the world produced 53.6 million tons of e-waste. |
The world’s e-waste will reach 74.7 million tons by 2030. That’s almost a doubling of e-waste in just 16 years. Today, only 15—20 percent of all e-waste is collected and recycled. |
| Why should we recycle e-waste? E-waste has many valuable things in it, such as gold, silver and copper. One smartphone battery can pollute 600,000 liters of water. |
| What can we do? ·Try to repair your electronics instead of buying new ones. ·Check for recycling organizations and donate your broken electronics. ·Remove (去除) any batteries because they need to be recycled separately. ·Tell others to recycle e-waste. |
| A．2014. | B．2019. | C．2022. | D．2030. |
| A．considering repairing rather than buying electronics. |
| B．recycling batteries together with other parts of electronics. |
| C．donating broken electronics to recycling organizations. |

【推荐1】The popularity of extreme sports (极限运动) is increasing in recent years, especially among young people. Most people do not experience much risk in their everyday life, so here are some sports that can satisfy their need for excitement.
| Surfing A surfer uses a board to glide (滑动) along on a breaking wave. There are now two kinds of surfing, based on the design of the board and riding style. Surfing is said to have been developed long ago in Polynesia, and it came to the rest of the world when Europeans first observed it. |

Early jumps were from hot air balloons in the eighteenth century, although it became an international sport in the mid-twentieth century. It is now popular both as entertainment and as a sport. |
| Mountaineering This sport is enjoyed as a relaxing activity as well as a sport, and combines hiking and walking. The original purpose was to reach high places where no one had been before. It then developed into a physically demanding sport. |

【推荐2】What’s the Silk Road? In history, it was an important international trade route (贸易路线) between China and the Mediterranean (地中海的) countries. The Silk Road began in Western Han dynasty and has a history of more than 2,000 years.
In the past, the Silk Road started at Chang’an (now Xi’an) and ended in Europe. It was about 6,500 kilometers long and went across 1/4 of the world.
The Silk Road got its name in the 19th century because Chinese silk was famous, and traders carried it to other places along this road. Of course traders also carried China’s porcelain (瓷器) and other things to the west. Glass, gems (宝石) and food like carrots from the west came to China. The Silk Road was very important to both China and the rest of the world. It was more than an international trade route. Lots of arts and science of other countries came to China across the Silk Road. In this way, languages and cultures influenced (影响) each other.

【推荐3】Do you find that you learn things faster than your parents sometimes? Congratulations, you could be right!
Scientists at Brown University, US, found that school-aged children learn new knowledge and skills faster than grown-ups. This has something to do with a chemical(化学物质) called GABA in our brains. It reduces brain noise so that we can learn things more easily. It also makes new knowledge stay longer in our heads.
The scientists scanned(扫描) the brains of children (8—11 years old) and adults (18—35 years old) before, during, and after doing a learning task. It turned out that when children learn new things, the number of GABA rises quickly. But there’s little change in adults’ brains. This tells us why children are better learners than adults.
The finding, the scientists said, should encourage teachers and parents to let children learn anything from riding a bike, playing an instrument or learning times tables(乘法表) in their childhood. It could also be used to help adults learn faster by increasing the amount of GABA in their brains.

【推荐3】Many have heard of shark fin soup (鱼翅汤). This famous and expensive dish is especially popular in southern China. But do you realize that you’re killing a whole shark each time you enjoy a bowl of shark fin soup?
When people catch sharks, they cut off their fins and throw the sharks back into the ocean. This is not only cruel, but also harmful to the environment. Without a fin, a shark can no longer swim and slowly dies. Sharks are at the top of the food chain in the ocean’s ecosystem (生态系统). If their numbers drop too low, it will bring danger to all ocean life. Many believe that sharks can never be endangered because they are the strongest in their food chain. But in fact, around 70 million sharks are caught and traded in this industry every year. The numbers of some kinds of sharks have fallen by over 90 percent in the last 20 to 30 years.
So far, no scientific studies have shown that shark fins are good for health, so why eat them? Help save the sharks!
