I signed up for a competition on garbage sorting on the Monday and I participated in the first round, a written test. Though there was many candidates, I succeeded entering the final with another student from my class. Last Friday where the final was held, my classmate and I played with the participants from other four classes, and answers all of the questions accurately. Finally, we won out! We were extremely happy what we brought honor to our class. When interviewing by the school TV station after the award ceremony, I expressed my prides in protecting our environment. The competition not only broadened my knowledge on the garbage sorting and increased the awareness of environmentally protection.

3 . When Alex Lin was 11 years old, he read a(an) ________ article in the newspaper, which said that people were ________ old computers in backyards, throwing TVs into streams, and dumping(丢弃) cell phones in the garbage. This was dangerous because e waste contains harmful ________ that can leak into the environment, getting into crops, animals, water supplies—and people.

Alex was really worried and decided to make it next project for WIN—the Westerly Innovations Network. Alex and six of his friends had ________ this organization to help solve community problems two years before.

But what could they do about this project with e-waste? The team spent several weeks gathering information about the harmful chemicals in e waste and their ________ on humans. They learned how to dispose (处置) of e-waste ________ and how it could be recycled. Then, they sent out a survey and found only one in eight knew what e-waste was, let alone how to dispose of it.

Alex and his friends went into ________. They advertised in the local newspaper and ________ notices to students, asking residents to bring their ________ electronics to the school parking lot. The drive lasted two days, and they ________ over 9,500 kilograms of e waste.

The next step was to set up a long-term e-waste drop-off center for the town. After some research, they’d learned that reusing is the best way to ________ electronic devices and it is seven times more ________ than recycling. So, they began learning to refurbish(翻新) computers themselves and distributed them to students who didn’t have their own. In this way, they could help students in the area and protect the environment at the same time.

For a________ solution to e waste, the drop off center wasn’t enough. Laws would have to be passed. In 2016,WIN helped ________ for an e waste bill in their town, which required companies that manufactured or sold electronics to take back e waste. The bill clearly ________ the dumping of e waste.

Because of the work of WIN, more and more people, like Alex and his team, are getting the message about safe disposal of e-waste. As Alex says, “Today’s technology should not become tomorrow’s harmful garbage.

6 . A shocking 53.6 million tons of electronic waste were discarded（丢弃）last year, a new UN-backed report has revealed. The report shows that e-waste is up 21%from five years ago. This isn't surprising, considering how many more people are adopting new technology and updating devices regularly to have the latest versions, but the report also shows that national collection and recycling strategies are nowhere close to matching consumption rates.

E-waste contains materials including copper（铜）, iron, gold and silver, which the report gives a conservative value of $ 57 billion. But most are thrown away or burned rather than being collected for recycling. Precious metals in waste are estimated to be worth $ 14 billion, but only $4 billion-worth is recovered at the moment.

While the number of countries with national e-waste policies has grown from 61 to 78 since 2014, there is little encouragement to obey and a mere 17% of collected items are recycled. If recycling does occur, it's often under dangerous conditions, such as burning circuit boards to recover copper, which "releases highly poisonous metals" and harms the health of workers.

The report found that Asia has the highest amounts of waste overall, producing 24.9 million metric tons (MMT), followed by Europe at 12 MMT, Africa at 2.9 MMT, and Oceania at 0.7 MMT.

But whose responsibility is it? Are governments in charge of setting up collection and recycling points, or should companies be responsible for recycling the goods they produce? It goes both ways. Companies do need to be held accountable by government regulations and have incentives to design products that are easily repaired. At the same time, governments need to make it easy for citizens to access collection points and deal with their broken electronics in a convenient way. Otherwise, they may turn to the easiest option-the landfill.

7 . When Simon Cane was in the second grade, he began learning about all the ways humans have an impact on the environment and really took those classroom lessons to heart in a way that set him apart from his schoolmates at his elementary school, P. S. 81, in the Bronx. “He told me we drove too much and made too much pollution,” his dad, Jonathan Cane, told Runner’s World. So Simon convinced his parents to start hanging their clothes to dry, taking the stairs instead of elevators, and other “green” measures.

“For much of kindergarten and first grade I rode my bike to Simon’s school with him on the back,” Jonathan said. “We had a lot of fun being outdoors. We’d stop to give our dog treats and generally enjoyed it.” As Simon got bigger, though, it wasn’t practical for him to ride on his father’s back, but it also didn’t make sense to ride together — both because of safety concerns and because there was no place to put away Simon’s bike. So, most of the time they drove the 1. 5 miles to school.

But in 2019, when Simon was going into third grade, the 8-year-old came up with a new way to help the planet: running the 1. 5 miles to P. S. 81. And Jonathan promised his son he’d join him for as long as he wanted.

“We did a test run one day in August, and decided to give it a go. To be honest, I thought he’d blink (眨眼)after it got really cold or rainy, but he never did,” Jonathan said. He recalled one day when the weather was particularly bad. “It’s really raining out there today,” he told Simon. “And Simon said, ‘Well then we’re going to get wet!’ He took pride in toughing it out, and it became a really fun family routine.”

Since the start, Simon has run with his dad and their black dog, Lola, and has even inspired his mom, Nicole Sin Quee, to join in. They soon became known as “the family that runs to school”.
