1 . Books are the most valuable cultural heritage. However, there are many ancient Chinese classics suffering from different degrees of damage due to various reasons.     1    

Bai Yuzhi,a post-90s restorer (修复师) at the Wuhan Library,graduated from Wuhan University in 2016 with a major in restoring ancient books. She is now the fourth generation of restorers at the Wuhan Library, Bai started practicing this technique during her after-class activities at college in 2014.     2     “I’m shy and not good at socializing, so this job suits me very well,” she said

    3     The restoration steps cannot be rushed. When restorers receive an ancient book, their first task is not to directly restore it but to observe it and record the book’s important details. After that, the restorers will open the book,remove every page, and repair it on the back side.     4     It may take one or two days to restore a single page. So it could take at least a month to complete the restoration of a whole book.

Bai has restored about 10,000 pages of ancient books in her over 10 years of work. The most difficult part of the restoration, according to her, is keeping everything under exact control over every stage.     5     If the paste (面糊) is too thin, the repaired pages may easily come off and become broken, which could affect the quality of the restoration. However, if the paste is too thick, the fixed pages will be tough, challenging to open.

With the advancement of science and digital technology, the methods for protecting ancient books have become more various.

2 . Mental health is a critical aspect of overall well-being, yet it is often ignored in our fast- paced society.     1     A well-cared and healthy mind leads to improved emotions, better relationships, and a more positive outlook on life.

    2     When we are stressed or upset, it is our mind’s way of reacting to negative stimuli(刺激). Good mental health allows us to cope with these emotions in a positive manner. In addition, when our minds are not clouded by negative thoughts or emotions it is easier to think clearly.     3    

Studies have shown that a person with good mental health lives longer and has a higher quality of life. The effects of positive mental health on the body are plenty, including reducing the risk of diseases and improving overall physical well-being.

Our mental state has a significant impact on relationships. People with good mental health are more likely to be kind and understanding.     4     This may further guarantee them with a stable emotional condition.

Mental health is as essential as physical health in maintaining a fulfilling life. If we run into trouble, don’t keep it to yourself.     5     With the right support, we can all enjoy the benefits of a healthy mind.

4 . While screen time is known to affect sleep, new research suggests that interactive (互动的) activities, such as texting friends or playing video games, put off and reduce the time spent asleep to a greater degree than passive (被动的) screen time like watching television, especially for teens.

The team studied the daytime screen-based activities of 475 teenagers using daily surveys. They asked the teens how many hours they had spent that day communicating with friends through social media and how many hours they spent playing video games, surfing the internet and watching television or videos. Finally, the researchers asked if they had joined in any of these activities in the hour before bed.

Next, the team measured their sleep time for one week. The researchers found that the teens spent an average of two hours per day communicating with friends via social media, about 1.3 hours playing video games, less than an hour surfing the internet and about 1.7 hours watching television or videos. For every hour throughout the day that they used screens to communicate with friends, they fell asleep about 11 minutes later averagely. For every hour to play video games, they fell asleep about 9 minutes later. Those who talked, texted or played games in the hour before bed lost the most sleep: about 30 minutes later.

Interestingly, David, lead author of the study, said the team found no obvious relations between passive screen-based activities and sleep. “It could be that passive activities are less mentally exciting than interactive activities,” said Anne, co-author of the study. “It’s a tricky situation,” she said. “These screen tools are really important to everyone nowadays, so it’s hard to put a limit on them, but if you’re really looking out for a teenager’s health and well-being, you might consider limiting the more interactive activities, especially in the hour before bed.”

6 . Culture shock is the experience that often accompanies moving to an unfamiliar place. It could be marked by feeling lost, anxious or hesitant.     1     You’ll become accustomed to the same things that initially “shocked” you! Read on for tips for overcoming culture shock in a short time.

When deciding to visit an entirely new place, don’t expect the traditions and cultures followed by your current home to be followed by the new land.     2     So keep your expectations low.

Even though it is an unfamiliar environment hosting different cultures and traditions from the one you’re used to, it’s vital to broaden your mind and be willing to try new things. Don’t be quick to form discriminatory judgments just because it is “odd”. Have a go at something different, like a food or clothing — different isn’t necessarily bad.     3    

Social psychologists claim that lack of information is the biggest contributor to prejudices. Talk to the local population and ask them about how their culture works instead of assuming the worst.     4     Plus, you’ll make some friends who can ease your transformation.

Keep yourself open-minded, await new experiences and familiarize yourself with the conduct of the people.     5     Go out there and have fun!

8 . According to Americans for the Arts, more than two-thirds of U.S. adults say that the arts “lift me up beyond everyday experiences.” Still, only 30 percent attended a concert of any type in 2017; 23 percent visited an art museum; six percent attended a literary event. Fewer than half actively created art of any kind.

What has caused this phenomenon is that we do not have time for art — we are weighed down by our day-to-day responsibilities. Maybe you like to play a little background music while you work but most of us rarely, if ever, went to see a live performance, let alone visited a gallery. And reading poetry? Perhaps not since high school.

Too often, we let the realities of life get in the way of the arts, which can feel insignificant by comparison. But this is a mistake. The arts might be the single most in-depth experience you will ever be given to explore the nature and meaning of life. And if you make time to consume and produce art, you will find your life become fuller and happier.

Some philosophers address the problem of life consumed by work and material pursuits. They argue that art provides relief from this routine, expanding our perspective and bringing us closer to true reality.   

Think of a time when you heard a piece of music and wanted to cry. Or recall your fast heartbeats as you stared at a delicate lifelike sculpture. Chances are that it probably stimulated (刺激) a sudden awakening, much like the shock from a lungful of pure oxygen after breathing in smoggy air.

If you are among those who feel that art is “pure pleasure to experience and participate in,” you might see it the same way you see eating out, or skydiving: as a luxury (奢侈品) item in your limited budgets of time and money. As such, it probably gets the same sort of treatment as any minor hobby. Don’t make this error. Treat art more like exercise or sleep: a necessity for a life full of deep satisfaction.

9 . Winners of the Broadcom MASTERS

Girls took the top prizes at the Broadcom MASTERS, a science competition for middle school students.

Alaina Gassler

Alaina won the $25,000 Samueli Foundation Prize for the project of reducing blind spots in cars. She was inspired to solve this issue by her mother who didn’t like driving her vehicle because its large A-pillar (A柱) design made her feel in danger. “I started to think about how blind spots were a huge problem in all cars,” said Alaina. So she worked on and solved it.
