Greenwood Seed Library

The Greenwood Community Garden opens its seed library for the season on Saturday 21 March, from 10 a.m. to 3 p.m., at the garden gate on Mill Road. Borrowing is free, and no membership (会员资格) is needed.

How it works

- Take up to six packets of vegetable or flower seeds and grow them at home.

- Save seeds from the healthiest plants in autumn.

- Return the same number of packets by 30 November.

Please note

- Every packet is labelled with its name, sowing (播种) month and the garden it came from.

- Bring small envelopes (信封) for the seeds you take; the paper ones run out by noon.

- Write on the white board what you borrow, so the next gardener knows what is left.

- Packets left at the gate after closing go into the shared box (共享盒).

Help

Volunteers are at the desk from 9 a.m. every Saturday. They will show newcomers how to save and store seed, and how to keep beans and pumpkins (南瓜) for up to four years. Children can try sunflower seeds, which are large enough for small hands.

21. When does the seed library open for the season?

A. On weekday mornings.

B. On every Saturday in March.

C. By the end of November.

D. On Saturday 21 March.

22. What is a borrower expected to do?

A. Grow six kinds of vegetables at home.

B. Pay a small fee before taking any seeds.

C. Return the same number of packets by late November.

D. Label every packet with the date it was borrowed.

23. What are newcomers offered at the desk?

A. Free envelopes full of tomato seeds.

B. Help with saving and storing their own seed.

C. Sunflower seeds to sell at the gate.

D. Space to grow flowers until next March.

In a reversal (逆转) of traditional family roles, a growing number of young Chinese are taking on the task of “re-raising” their parents — teaching them digital skills, buying their health supplements (保健品) and even taking them to concerts. The trend, discussed online under the hashtag (话题标签) “I re-raised my parents after growing up”, has drawn attention for redefining filial piety as thoughtful care rather than passive duty.

At the heart of it lies a widening digital divide (数字鸿沟). Older generations grew up in a relatively stable world, while their children came of age with smartphones and algorithm-driven recommendations. Young people thus hold a clear advantage in finding information online — skills many parents have yet to master.

Hang Yunjie, an 18-year-old freshman (大一新生) at Beijing University of Chemical Technology, met the gap when he bought fish oil for his father and reading glasses for his mother. His parents had long trusted television advertisements. Hang read online reviews instead. “My father agreed my choice was better than his usual brand, but he still expects me to deal with it all next time,” he said. “He does not want to learn how to find the information himself.”

For Xu Yu, a 31-year-old office worker in Beijing, the deeper change came when he bought his parents new smartphones and showed them how to order food through an app. “They used to come home tired and still had to cook,” he said. “Now they can order what they like. When I was little they worried about my meals.”

Yu Tianxin, a 19-year-old at Beijing Foreign Studies University, went further: she went with her mother to three concerts by pop singer Zhang Jie, arranging everything from tickets to hotel rooms. “Conventional filial piety (孝道) repays a debt — they raised me, so I should look after them in old age. Going to concerts with my mother grows out of real affection.”

Yao Huasong, a sociology professor at Guangzhou University, views the shift as a welcome change between generations. Writing in China Youth Daily, he set out three conditions behind it: young people's stronger digital and information literacy (素养), their willingness to spend time and patience talking with their parents, and parents' growing readiness to set aside traditional authority (权威) for a more equal dialogue.

24. How did Hang Yunjie choose the health supplements?

A. By following television advertisements.

B. By comparing products through online reviews.

C. By asking his father about his usual brand.

D. By taking advice from the local pharmacy.

25. What do Hang Yunjie's words suggest?

A. His father is too old to use a smartphone.

B. Cheaper brands work better than famous ones.

C. Buying things for his father has not made him want to learn.

D. He plans to stop shopping for his parents quite soon.

26. What can be learned from Yao Huasong's three conditions?

A. The trend depends on change on both sides.

B. Parents have given up their role in the family.

C. Young people are losing interest in their work.

D. Digital skills matter more than family feelings.

27. Which title best summarises the passage?

A. Filial Piety, Learned Again in a Digital Age

B. How to Shop Online for Your Parents

C. Parents Refuse to Learn Anything New

D. The Rising Cost of Health Supplements

C

Plastic pollution is one of the most persistent (持久的) environmental problems we face. Discarded plastic piles up in the oceans and threatens marine life. Conventional plastics break down slowly because microorganisms

struggle to digest the synthetic polymers they are made from. Instead of disappearing, they gradually break into ever smaller pieces — microplastics and nanoplastics.

Plastic is not entirely beyond nature's reach, though. Bacteria settle on its surface and form thin communities called biofilms (生物膜), creating a distinctive microbial ecosystem that scientists have named the “plastisphere”.

Researchers at the University of Konstanz have now found an unusual enzyme that may explain how some bacteria are becoming better equipped to attack certain plastics. It digests particular polyesters and biodegradable (可生物降解的) plastics, and it has one unexpected ability: it can also break down penicillin (青霉素), hinting at a possible link with antibiotic resistance. Its nickname, the “Pac-Man enzyme”, comes from an unusually wide active site — the opening where the chemical reactions take place.

Biologists Harry Lerner and David Schleheck set out to watch the whole process of microbial decomposition. They wanted to know not only whether the material could be completely broken down, but which organisms did it and how. In the university's botanical garden they buried small pieces of LCAP film in the upper humus (腐殖质) layer, about ten centimetres deep — the layer where cellulose and cutin (角质), a plant polyester (聚酯), are broken down naturally.

In the laboratory, cellulose and the bioplastics PHBV and PCL served as comparisons, along with high-density polyethylene (HDPE) and untreated soil. All the bioplastics disappeared within roughly 250 to 330 days. Cellulose broke down in about 80 days. HDPE showed almost no change.

Schleheck is cautious. Humans have put large amounts of plastic into the environment for only 50 to 75 years, and in theory it should feed bacteria, yeasts and fungi as a source of carbon and energy. “They would surely like to use it as a growth material, but they cannot,” he says. “The materials are indigestible to microbial metabolism (新陈代谢), so they are hardly degraded.”

28. What surprises researchers about the new enzyme?

A. It was named after a video game character.

B. It was discovered deep in the ocean.

C. It feeds on high-density polyethylene.

D. It can break penicillin down as well.

29. What does “plastisphere” in paragraph 2 refer to?

A. The layer of soil where plant polymers break down.

B. The microbial ecosystem living on plastic waste.

C. The process of breaking plastics into small pieces.

D. The ability of bacteria to digest synthetic polymers.

30. What does Schleheck suggest about plastic waste?

A. Bacteria will learn to digest it within decades.

B. Bacteria avoid plastic because it is poisonous.

C. Nature alone is unlikely to clear most of it.

D. The plastisphere has stopped growing since the 1970s.

31. What does this passage mainly focus on?

A. A wide-opening enzyme shows how bacteria attack biodegradable plastics.

B. Biodegradable plastics are unwise choices for packaging.

C. Antibiotics have lost their effect in forest soil.

D. Microplastics in the sea now support rich life.

D

Stress does more than shape how we feel; it also shapes what we remember, particularly when an experience is emotionally intense or personally meaningful. Scientists have long known that cortisol, a hormone released under stress, can strengthen emotional memories. What has been far less clear is how this happens in the brain.
