7 . The process of sorting through my childhood stuff started out easy. At first, I was excited to toss everything out. But as the bedroom emptied out, I felt a creeping sense of sadness. My childhood was over, and I entered full-fledged (成熟的) adulthood. And I wondered:     1     In short, yes.

    2     That’s because going through your old stuff can possibly stir up difficult emotions or sweet memories. Whatever emotions pop up, accept them, and it will help you process it faster.

Before you start sorting, determine how much storage space you’re willing to devote to your childhood items.    3     You may have limited space for old stuff. But listen to your heart. If you’re sentimental and you want to hold on to stuff, hold on to it. You canal ways get rid of it later.

During this process, it can be useful to have someone you trust by your side. They can help you honor the memories associated with each object and let go.     4     They know which life experiences mean the most to you.

And you don’t have to pile your childhood stuff in the attic (阁楼).     5     You can take photos, which you can revisit any time on your phone or computer. Or you can turn them into an art project and display it in a shadow box.

Remember, there is someone who care enough to hold on all old stuff for you. This is a value of all of the time and effort and money your parents have poured into you. This has been saved in love.

8 . When my mother visits us from Korea, she spends countless hours preparing homemade meals every day.

She thoughtfully plates and _________ our family at the table. She pours the soup for her little granddaughters first, carefully checking its temperature to _________ it will not burn their tongues. She adds more salt and pepper into mine and her son-in-law has the most substantial portion (份). It is remarkable how effortlessly she makes a meal that feels _________ for each of us.

However, her cooking begins much earlier at the grocery store. She becomes the most cruel _________ of vegetables. “Iceberg lettuce goes bad soon.” “Those tomatoes _________ to be firmer, redder.” What’s more, all of our family’s wants are _________ imprinted inside her brain and _________ her hands as she adds items to the basket.

When you put so much _________ into a meal, it becomes a ritual (仪式). It is the only time when everyone _________, sits down and takes the time to taste each bite. The dining table __________ into the centre of the family’s conversation and connection. As we __________ each other’s struggles and victories, we offer support and advice. We update each other on our work projects and __________ ideas for future vacation plans.

In a fast-paced era, creating a homemade meal might seem highly __________. However, my 68-year-old mother treats it with such __________. I know it’s her way of expressing __________— that extra ingredient that goes into cur every meal.

9 . The best way to really see a city is to explore it slowly by walking around. It’s easy, healthy, and also benefits the environment. When on foot, you can do as the locals do. Here’s what you can find under your own steam.

Best for families: Planetenweg, Zurich

The 2,854 ft-tall, forest-covered peak that towers from Zurich’s doorstep is the envy of every European city. To get there, try the four-mile, two-hour-long route on Planetenweg. This family-friendly wander cuts in and out of spruce forests and gives you a proper flavour of being up in the mountains without ever actually leaving the city.

Best for arty vistas: Ekebergparken, Oslo

Come at sunrise or sunset, when the sky blazes above shining fjords (峡湾) and transforms the dark, rocky islands into shadows, and you can see why Oslo’s Ekebergparken inspired Munch to paint The Scream. Starting at the Ekebergparken Museum, the two-mile sculpture trail (小道) winds through pine, fir and ash forest, where plenty of phenomenal works of art await — Dalí’s surrealist Venus de Milo with Drawers and Damien Hirst’s Anatomy of an Angel among them.

Best for getting off the beaten track: Vienna Ugly, Vienna

The guided walks led by locals across Vienna dive into neighbourhoods that are off the usual tourist trail. Among them is Vienna Ugly, a 2.5-hour wander through Leopoldstadt and Innere Stadt. At the end of the tour, you’ll vote on which of the city’s buildings are the ugliest. Tours from £9.

Best for architecture: Ørestad, Copenhagen

Copenhagen rode high as World Capital of Architecture 2023. A guided walk with the Danish Architecture Center throw you in at the architectural deep end for 2.5 hours, taking you to Copenhagen’s Ørestad neighbourhood on the island of Amager. From £18.

10 . A new drug-delivery system could replace needles with puffs (股) of air. Gassensmith studies bioengineering at the University of Texas. His team’s new tech goes beyond patient comfort, though. The device quickly delivers drugs without touching the bloodstream. And that could reduce the risk of spreading disease. He tested it out on his own arm. “I could feel it, but it wasn’t painful,” he reports.

The technology works by blowing in a puff of air through the skin. That gas carries a powder made of tiny bits of vaccine (疫苗) wrapped in metallic crystals (晶体). The crystal coating is really strong, Gassensmith says. As a result, the vaccine powder does not have to be refrigerated while stored. The air contains carbon dioxide, or CO₂. Once in the body, the CO₂ that carries the powder will mix with water. It creates a weak acid that breaks down the crystal cover. Released, the vaccine bits are then able to enter the bloodstream.

This gas-based drug-delivery system is an upgrade over previous ones. For instance, adjusting the gas that carries the vaccine powder can customize how fast the tiny crystal capsules release the drug. Testing showed that the drug released fastest when delivered with carbon dioxide. Plain air led to a slower, gentler release. Vaccines work best when released slowly. That allows them longer contact with the immune(免疫) system. But the team hopes the device could work for other medicines too. And some medicines must be released quickly. One such example is insulin, a crucial drug for many people with diabetes.

Fear of needles keeps many people from getting vaccinations. Gassensmith is optimistic that this new system might get around that. Future research must ensure that gas-delivered vaccines build immunity to disease as expected, said Weniger, a doctor, who studied vaccine technology for 30 years for the U. S. Centers for Disease Control and Prevention.
