4 . Plastic—Eating Worm
Humans produce more than 300 million tons of plastic every year. Almost half of that ends up in landfills(垃圾填埋场) , and up to 12 million tons pollute the oceans. So far there is no effective way to get rid of it, but a new study suggests an answer may lie in the stomachs of some hungry worms(幼虫).
Researchers in Spain and England found that the worms of the greater wax moth(大蜡螟) can break down polyethylene(聚乙烯), which accounts for 40% of plastics.
That is to say, part of plastics can be consumed by this kind of worms. The team left 100 wax worms on a plastic shopping bag for 12 hours, and the worms consumed and broke down about 92 milligrams, or almost 3% of it. To confirm that the worms' chewing alone was not responsible for the polyethylene breakdown, the researchers made some worms into paste(糊状物)and applied it to plastic films. 14 hours later the films had lost 13% of their mass—apparently broken down by enzymes(酶)from the worms' stomachs. Their findings were published in Current Biology.
Federica Bertocchini, co—author of the study, says the worms' ability to break down their everyday food—beeswax—also allows them to break down plastic." Wax is a complex mixture, but the basic bond in polyethylene, the carbon—carbon bond, is there as well," she explains. "The wax worm developed a method or system to break this bond."
Jennifer Debruyn, a microbiologist at the University of Tennessee, who was not involved in the study, says it is not surprising that such worms can break down polyethylene. But compared with previous studies, she finds the speed of breaking down in this one exciting. The next step, DeBruyn says, will be to identify where the enzyme comes from. Is it an enzyme produced by the worm itself or by its gut microbes(肠道微生物)?
Bertocchini agrees and hopes her team's findings might one day help make use of the enzyme to break down plastics in landfills. But she expects using the chemical in some kind of industrial process—not simply "millions of worms thrown on top of the plastic."

5 . A Hug from a Teenage Boy
Fifteen years spent in the field of education have provided Nancy Marra with many treasured moments. One of the most endearing happened when she was teaching second grade.
That year, she decided to plan something special for the children: a Mother’s Day tea. After all the preparations were made for it, each child took home an invitation. Nancy was surprised and relieved to see that every mother was planning to attend. She even invited her own mother.
Finally, the day arrived. That afternoon, each child lined up at the classroom door expecting the arrival of his or her mom. As it got closer to starting time, Nancy looked around and her eyes quickly found Jimmy. His mother hadn’t shown up and he was looking upset.
Nancy took her mother by the hand and walked over to Jimmy. “Jimmy,” Nancy said, “I have a bit of a problem here and I was wondering if you could help out. Since I’m going to be really busy today, I was wondering if you could keep my mother company.”
Nancy’s mom and Jimmy sat at a table with two other mother-child pairs. Jimmy served Nancy’s mom her treats, presented her with the gift Nancy had made, and pulled out and pushed in her chair, just as they had practiced the day before. Whenever Nancy looked over, her mom and Jimmy were in deep conversation
Ten years later, Nancy was at a high school to take a senior class on a field trip, and there was Jimmy. On the way back, Nancy had the students complete an evaluation form of their trip. She collected and checked the forms one by one.
When she came to Jimmy’s evaluation page, he had written, “Remember our Mother’s Day tea we had in second grade, Mrs. Marra? I do! Thanks for all you did for me, and thank your mother, too.”
As they began unloading at the school, Jimmy made sure he was the last one to go. Nancy told him she really enjoyed what he had written. He looked rather embarrassed, mumbled (咕哝) his own thanks, and then turned to walk away. As the bus driver began pulling the bus away, Jimmy ran back and knocked on the bus door. He jumped back on board and gave Nancy a big hug. “Thanks again, Mrs. Marra. No one even knew my mom didn’t make it that day!”
She ended her workday with a hug from a teenage boy who had probably stopped hugging teachers years ago.

7 . The day I heard that the Rainbow Bookstore was closing after 50 years of business, I was heartbroken. The bookstore, which was a famous fixture in the neighborhood, was a place where anyone could visit and connect through their love of books.
When I hurried to the store, I saw that the books were already being packed into boxes. I had a long chat with Casey, the store’s elderly owner. Sighing deeply, he told me how it was becoming difficult to run an independent bookstore. Most young people preferred reading e-books on tablets. More and more customers were being attracted by chain stores and online discounts. I tried to think of some words of sympathy, but I had to admit that the Rainbow Bookstore couldn’t stay in business much longer.
A few months later, I was back in the neighborhood during my spring break vacation and was surprised to see that the Rainbow Bookstore was still there and open for business. Its outside surface hadn’t changed, but inside it was like a different world. In one area, a book reading was being delivered. Nearby customers were gathering around shelves selling books, posters and other best-seller-themed gifts. The large board in the corner had been replaced by a big screen, where customers’ comments on the month’s best-seller were being displayed. Clearly, the Rainbow Bookstore was in good, creative hands.
I was told that the community had decided to work together on a campaign to save the Rainbow Bookstore. The campaign had been led by Jennifer Oakley, a saleswoman who had grown up in the neighborhood and who had now taken over the bookstore from Casey.
Under Jenifer’s leadership, the bookstore was being turned into a place for literature-loving members of the community to get together. It had a cafe selling organic food, and there were now more community events such as book readings, poetry recitals and even jazz concerts and movie nights, where people could gather to share an experience that couldn’t be downloaded.
I’m so pleased to see that creativity has brought the old bookstore into the 21st century!

9 . You might have noticed how everyone is addicted to their screen during family gatherings or bonding with friends. Disconnecting from devices might be challenging.
If you want to spend quality time with each other, you and your friends need to sacrifice your screen time. Turning off your devices could be the first step you can do. It could also be one of the house rules when you are together. However, everyone in the group must be willing to cooperate or else the purpose might be defeated. By turning off your devices, it would focus the atmosphere more on your bonding. Everyone could feel more welcomed and invited.
So what are the alternatives other than staring at the screen? Before the trend of high-tech devices, a board game had always been the source of entertainment when a group of friends wanted to have some fun.
Another helpful way to start a conversation with your friends is through playing question games.
A.It is better for you all to agree on this matter. |
B.So why not bring these classic activities back? |
C.You and your friends could attend more to each other. |
D.Being interactive is the key in bonding with your friends. |
E.However, there are ways to spend time with your friends without using them. |
F.Entertainment isn’t the only way to interact with your friends. |
G.The main idea of this kind of game is to take turns in involvement. |
