4 . Around the world, people are realizing the significant problems caused by plastic waste. In the last 65 years, we have become increasingly dependent on plastic. It’s easy to understand why: it’s cheap to produce, light — therefore easy and cheap to transport — and incredibly strong and durable.     1    

One popular solution to the problem is to prohibit single use plastics. In the British supermarkets, shoppers are encouraged to make more environmentally-friendly choices in packing and transporting their food.     2     Some governments have even promised to ban the use of single-use plastic altogether by the not-too-distant future.

However, such plans may not be beneficial to eliminate (消除) the use of single-use plastic altogether.     3     This is not just because of its low cost. It’s also because infection and cross-contamination (交叉感染) are minimized. Plastic packaging is also crucial in the food industry. It ensures that food is safe for consumers.

Another issue is that alternative materials to plastic are often more environmentally harmful than plastic. Take paper bags, for example.     4     The process requires cutting trees, the emission of greenhouse gases and the production of poisonous chemical waste. Even more pollution is created when paper bags break down.

Clearly there is a need to reduce plastic waste and its impact on the environment.     5     Industries that rely on single-use plastics for people’s health and safety must be considered. Moreover, alternative materials must be evaluated strictly regarding their own environmental impact.

A．But it’s these advantages that also make it so harmful.

B．They are very fragile and rarely reusable, unlike plastic.

C．One of the fields where single-use plastic has a vital role is medicine.

D．However, simply banning their single use may not be the best option.

E．It also boosts the local economy and save costs in managing littering and waste.

F．Bans on single-use plastic items like drinking straws are also coming into place.

G．According to a research, they require four times more energy when produced than a plastic bag.

6 . Since the age of 5, Laura Lee has had what most would consider an odd habit-she collects toilet rolls. At that time, she didn’t know this habit would eventually become a nationwide recycling campaign.

In December 2018, as a 16-year-old student of Nanyang Girls’ High School in Singapore, Lee founded ToiletRollSG, a national project that aims to collect 1,000 kilograms of cardboard cylinders — or about 150,000 pieces. As of February of 2021, Lee, who was studying at Hwa Chong Institution, had collected 860 kg of toilet rolls, reported Singapore Today. Slightly later, she was awarded Singapore’s National Environment Agency’s Ecofriend Awards, which recognizes individuals for their contributions to the environment, under the Youth and Students category.

But why did she choose toilet rolls? “They are convenient to collect and also one of the purest forms of waste to recycle because they are made of only one material,” Lee told Singapore Today. “Project must be economically practical too. For example, it’s more difficult to recycle pens because they are made up of too many different materials like rubber casings, metals and plastics which require more resources to separate.”

Lee went into a partnership with the waste management firm Veolia, which gives her five cents for every 1 kg of toilet rolls collected.

She organized “toilet roll challenges” within Nanyang Girls’ High School and worked with cleaners to collect used toilet rolls from school toilets. She also conducted talks about ToiletRollSG. But due to COVID-19, she has been unable to conduct physical talks, so she raises awareness about different social causes through her Instagram Live series called On A Roll.

One of the biggest challenges Lee has faced has been others doubting her due to her young age. “I always have to use my actions as well as the different things I’ve done to prove that I’m passionate and know about this,” she told The Straits Times.

Lee will donate the money collected to a social cause that is focused on community health.

8 . GREAT BOOKS TO TEACH CHILDREN ABOUT CLIMATE CHANGE

Here is a shortened list of books sponsored by the magazines TIME and TIME for Kids that are suitable for primary schoolers. To make the list, we considered how age-appropriate the material was, and whether the tone and story line left the reader feeling engaged and empowered rather than anxious or confused.

Experts recommend the youngest kids to read books that explore the beauty and fragility (脆弱) of nature. When developing an appreciation for the world around them, they can switch to books that show the cause and effect of how humans treat our planet, and why it’s important to respect the environment. For older primary school kids, picture books can illustrate how our use of fossil (化石) fuels contributes to global warming. Most of the books on the list also offer lessons about how children, families, schools, and communities can make a difference.

THANK YOU, EARTH: A LOVE LETTER TO OUR PLANET By April Pulley Sayre This photography book shows to us plants, animals and landscapes in vivid colors and descriptions. From up-close images of insects to pictures of mountain ranges, the pages introduce children to the planets’ diversity in a simple but effective way.	THE LORAX By Dr. Seuss Thanks to its rhyme, and whimsical illustration, this classic tale is suitable for young children who can grasp the scarcity of natural resources, and also older kids who can see a danger in valuing profits over long-term environmental harm.
WE ARE WATER PROTECTORS By Carole Lindstrom A tribute to native tribes that are protecting the planet, this book vividly shows the harms of oil pipelines. Kids will see the value of community action, while adults will recognize the story of the native tribes Standing Rock Sioux’s fight against the Dakota Access Pipeline.	POLAR BEAR, WHY IS YOUR WORLD MELTING? By Robert E. Wells This book introduces the greenhouse effect with illustrations showing how sunlight gets trapped. It then explains fossil-fuel energy, and our reliance on it for electricity and transportation. The pages are full of science.

9 . 阅读下面材料，根据其内容和所给段落开头语续写两段，使之构成一篇完整的短文。

It was a lovely spring morning in the mountains of my home. Here was full of natural atmosphere. The sky was blue, the sun was warm, and the air was fresh. As driving along the winding road, I could see thousands of wild flowers in bloom. When I turned round, I slowed down as I saw some volunteers picking up garbage along the side of the road. I just smiled as I saw them doing some cleaning in spring for Mother Earth and my mind suddenly floated back in time to another spring morning long ago.

When my children were younger, I used to walk along a small route around the lake near my home. It was also on a spring morning that I noticed much garbage lying along the route. The next day, I brought a big garbage bag and started to slowly pick up the garbage along my way. All kinds of deserted objects lay all over the floor. There were pop cans, plastic water bottles, wrappers for candy bars, empty chip bags, pieces of broken fishing line and even an old shoe. Every time I stopped, I picked up a piece of garbage. And I even fished some garbage out of the edge of the water. By the time I circled the lake, the garbage bag had been nearly full.

Tired but happy, I put the bag in an empty garbage can. I stopped before I headed home and took one last look at the lake as the sun set. It looked more beautiful than ever and I felt like the angels were looking down upon it with me and sharing my smiles.

I always think that at times this world’s problems can seem overwhelming and you may wonder what you can do to make a difference. But the truth is that every good thing you do matters a lot! I do believe every time I stop to pick up a single piece of garbage, I can make a difference. As my children are adults now, I decide to spend more time protecting the environment.
