1 . Here are four books for teens to read before they turn 18, including a mix of classics, young adult fiction and non-fiction. Parents may even want to re-read.
The Hate You Give by Angie Thomas
This may be one of the most powerful books of the decade, which deals with themes of race and community in a moving way that will speak to any teen. This book is an award winner and one for both parents and their children.
The House on Mango Street by Sandra Cisneros
This book is a series of short writings surrounding the experiences of Esperanza Cordero, a Latina girl living in Chicago. It will take readers along a coming-of-age story that explores happiness, heartbreak and everything in between.
The Curious Incident of the Dog in the Night-Time by Mark Haddon
This novel centers around a boy with autism (自闭症) and a mystery that the readers get to experience from the viewpoint of Christopher John Francis Boone. He doesn’t understand human emotion, and living this mystery through this angle is a thoughtful way for teens to understand the ways in which people can differ yet also be the same.
A Wrinkle in Time by Madeleine L’ Engle
Though this book recently became popular again due to the release of the movie version, the movie is not a substitute for this beautiful story about family and the process of embracing who you truly are through the angle of space and time exploration.

2 . New research led by scientists at the University of Massachusetts Amherst has revealed that the spiny pollen (带刺花粉) of plants in the sunflower family can reduce infection of a common bee parasite (寄生生物) by up to 94 percent. The sunflowers'spiny pollen can destroy a parasite called C. bombi (熊蜂短膜虫), which has been significantly reducing bumblebee populations.
To investigate how sunflowers help bumblebees resist C. bombi, the researchers separated the spiny outer shell of the pollen from the chemical metabolites (代谢物) in the pollen’s core. They then mixed the spiny pollen shells of sunflowers, with the chemistry removed, into the pollen fed to one group of bees.
Another group was fed wildflower pollen with sunflower metabolites and no sunflower shells. The researchers discovered that the bees that ate the spiny sunflower pollen shells had the same response as bees feeding on whole sunflower pollen. These bees had a markedly reduced risk of C. bombi infection compared to those fed sunflower metabolites.
Bumblebees, which are vital pollinators of crops and wildflowers, are experiencing a rapid decline in their populations worldwide. Habitat loss due to urbanization and agricultural intensification is the greatest threat to bumblebees. Climate change is also taking a toll on bumblebees. As temperatures rise, bumblebees are forced to move further north to cooler climates, which can affect their ability to find food and nesting sites. Pesticide use is another significant threat to bumblebees. These chemicals are harmful to them and can damage their navigation and immune systems, leading to reduced reproductive success. Bumblebees play a vital role in maintaining healthy and diverse ecosystems. Understanding how sunflowers protect bees from disease could help us identify other flowers that have similar protective properties. Through this, researchers can work towards developing new strategies to help conserve bumblebees.

6 . Pressing the power button to turn off your computer can save time—but can it also damage your machine? Raise your hand if losing your computer would be a serious hindrance to your career, or if, at the very least, you’d lose a whole lot of important information. Yeah, us too. And yet we tend not to treat our computers with the care about this advantage; many of us are probably guilty of these things you’re doing that shorten your laptop’s life.
One of the directives you’ll commonly hear when it comes to computer upkeep (保养) is that you should shut down your computer properly by clicking the “Shut Down” button onscreen, rather than pressing and holding the “Power” button, so that it shuts down immediately. But when you click “Shut Down,” every program needs to close, and that can be time-consuming. How bad, really, is shutting your computer down with the power button?
“Shutting down a system properly is known as a ‘graceful shutdown’, which sends a signal to the respective operating system so that it can save its state before turning the hardware off,” a tech expert Damien Mason says. However, Mason adds that this forced shutdown can even be beneficial, in certain situations. “Hard shutdowns can be a saving grace when a system crashes or as a safety way to prevent hackers,” he says. But you still shouldn’t make a habit of doing it. Mason says that graceful shutdowns are still a preferred method, which avoids interrupting tasks conducted by the operating system and allows programs to properly save.
You should press the “Power” button carefully, but it’s not a death knell for your machine. There are plenty of other things you may be doing that are most likely worse. For instance, not shutting down your computer at all—or even only doing it rarely—can be far more damaging to it than a forced shutdown.

7 . Coronavirus survivors have spoken out about what it is like to contract the disease, which has infected more than 132,000 worldwide and killed over 5,000 people.
As fears over the coronavirus pandemic spread, there’s one question that comes up again and again — how bad is it really? The severity of symptoms can vary dramatically, from a mild sniffle to a hellish feeling of suffocation.
Here are some of the coronavirus patients' stories:
Jaimuay Sae-ung, 73
Jaimuay Sae-ung was the first Thai national to contract coronavirus, becoming ill in December.She experienced a fever and a bad cough, then developed pneumonia (肺炎) while in quarantine.After 10 days, Jaimuay’s condition had improved and she was eventually discharged following two negative test results.
Carl Goldman, 67
Carl Goldman, from Santa Clarita in California, was on the Diamond Princess cruise ship and later tested positive for coronavirus.He said the virus “hasn't been that bad”.He developed a fever and “a bit of a cough” during his flight back to America and was quarantined on his return.He said: “The sickest I've ever been was when I had bronchitis (支气管炎) several years ago.This has been much easier — no chills, no body aches.I breathe easily and I don't have a stuffy nose.“My chest feels tight and I have coughing spells.If I had been at home with similar symptoms, I probably would have gone to work as usual.” After having the illness for one month, Carl now has no symptoms, but is still testing positive.
Marc Thibault, 48
Teacher Marc, from Rhode Island, in the US, led a school field trip to Italy, France and Spain last month and was admitted to hospital on February 27, five days after he returned home.A week later he was diagnosed with coronavirus.He said the illness had hit him “like a hurricane”.Marc, a school vice principal, said: “You feel like you're asphyxiating, and you’re panicking because you can’t breathe.He added that he felt “one inch from death” and remains in intensive care.
