“People are ruder today because they are rushed and more ‘time poor' than ever before, ” says Patsy Rowe, “ Manners have fallen off the radar(雷达). ” Due to our strong attraction to electronic equipment it is a wonder more people don't wake up each morning and greet the singing birds with a complaint（抱怨）about the noise. Here are some examples of rudeness.

    Some people prefer to do almost everything over the internet. To them, dealing with an actual human is like an evolutionary step backward. It feels very slow because humans don, t work at 4G speeds. When you have dinner with friends, you will often notice someone paying more attention to his mobile phone. We have programmed ourselves to think that every new message brings life-changing news, so taking calls and checking our texts are more important than talking to the people we are with. What is worse, some people even tend to send anonymous（匿名的） rude messages by email.

    However, rudeness is never acceptable, Don, t assume it is OK to be rude if the person you, re in touch with won, t recognize you. If you have something awful to say, have the courage to face the person and say it, write a letter or email and sign it, or forget it. Upsetting people with unsigned messages is cruel and disgusting.

    We shouldn′t blame technology for our shortcomings. Technology is here to help us, but we should not allow it to take over our lives. An important step is acknowledging our shortcomings. People spend a lot of time pointing out bad manners but it would be even more help if we′d publicly acknowledge good manners when we see them.

    Shenzhen is a shopping paradise for visitors. Following is a list of the most popular shopping areas in the city.

    North Huaqiang Area

    The most prosperous shopping area in Shenzhen, it is home to dozens of market places for electronic products, home appliances, timepieces, clothing and jewelry. Some market places each house hundreds of shops, from flagship stores selling big brands to small boutiques where you can bargain.

    It is also a great place to dine, with plenty of restaurants offering various Chinese cuisines and foreign brands like Pizza Hut, Hagen Dazs and AijiSen.

    Dongmen Area

    One of the oldest commercial centers in Shenzhen, this area highlights a walking street flanked by humming stores. It is a good place to buy clothes, handbags, fashion accessories, jewelry, handicrafts, toys and small electronic gadgets.

    MixC Shopping Mall

    It is the city's largest shopping mall and one of the most luxurious, selling clothes, cosmetics and fashion accessories.  There is a large indoor ice skating rink, a movie theater and a super market selling many imported goods. You can also find quite a few foreign restaurant brands here, including Pizza Hut, Starbucks and a Japanese noodle house.

    Shekou

    Sitting by a beautiful cove in western Nanshan District, this quiet place is frequented by many expatriates living in Shenzhen. There are stores selling antiques, collectibles, handicrafts and souvenirs, as well as bars and restaurants offering Western food.

    At the age of 83, I'm reading more and dusting less. I'm sitting in the yard and admiring the view without caring about the weeds in the garden. I'm spending more time with my family and friends and less time working.

    Whenever possible, life should be a pattern of experiences to savor, not to suffer. I'm trying to recognize these moments now and cherish them.

    I'm not "saving" anything; we use our good china and crystal for every special event such as losing a pound, or the first Amaryllis blossom. I wear my good clothes to the market. I'm not saving my good perfume for special parties, but wearing it for clerks in the hardware store and tellers at the bank.

    "Someday "and" one of these days" are losing their positions in my vocabulary. If it's worth seeing or hearing or doing, I want to see and do it now.

    I'm not sure what others would have done had they known they wouldn't be here for the tomorrow that we all take for granted. I think they would have called family members and a few close friends. They might have called a few former friends to apologize and mend fences for past quarrels. I like to think they would have gone out for a Chinese dinner or for whatever their favorite food was.

    It's those little things left undone that would make me angry if I knew my hours were limited. Angry because I hadn't written certain letters that I intended to write one of these days. Angry and sorry that I didn't tell my husband and parents often enough how much I truly love them. I'm trying very hard not to put off, hold back, or save anything that would add laughter and luster to our lives. And every morning when I open my eyes, I tell myself that it is special. Every day, every minute, every breath truly is a gift.

    This is a time of year when high school students and their families are thinking hard about college. As seniors, juniors, and parents identify their top choices, discussions typically focus on the college itself. Is the institution small or large? How strong are the academics? What is the social life like? Do I like the campus? Such considerations are important, but they can cover the all­important question: Where will these college years lead?

    Applicants should think seriously about which college on their list can best prepare them for the real world. They should look for campuses that offer well­structured programs to help them form a direction for their lives and develop the capacity to take steps along that path.

    One of the most striking recent phenomena about college graduates in America has been the "boomerang" student: the young person who goes away to college, has a great experience, graduates, and then moves back home for a year or two to figure out what to do with his or her life. This pattern has left many graduates — and their families — wondering whether it makes sense to spend four or more years at college, often at great expense, and finish with no clear sense of who they are or what they want to do next.

    The trend points to one of the great shortcomings of many of our nation's leading colleges and universities. Structured opportunities to think about life after graduation are rare. The formal curriculum focuses almost universally on the academic disciplines of the arts and sciences.  Advising on how various majors connect to pathways into the workplace is typically haphazard (没有条理的). Career planning offices are often shorthanded and marginal (不重要的) to college life.

    It doesn't need to be this way, and in recent years some of the country's top colleges have enriched their academic offerings with opportunities for students to gain real­world experiences.

Human speech contains more than 2,000 different sounds, from the common "m" and "a" to the rare clicks of some southern African languages. But why are certain sounds more common than others? A groundbreaking, five-year study shows that diet-related changes in human bite led to new speech sounds that are now found in half the world's languages. 

More than 30 years ago, the scholar Charles Hockett noted that speech sounds called labiodentals, such as "f" and "v", were more common in the languages of societies that ate softer foods. Now a team of researchers led by Damián Blasi at the University of Zurich, Switzerland, has found how and why this trend arose. 

They discovered that the upper and lower front teeth of ancient human adults were aligned(对齐), making it hard to produce labiodentals, which are formed by touching the lower lip to the upper teeth. Later, our jaws changed to an overbite structure(结构), making it easier to produce such sounds. 

The team showed that this change in bite was connected with the development of agriculture in the Neolithic period. Food became easier to chew at this point. The jawbone didn't have to do as much work and so didn't grow to be so large. 

Analyses of a language database also confirmed that there was a global change in the sound of world languages after the Neolithic age, with the use of "f" and "v" increasing remarkably during the last few thousand years. These sounds are still not found in the languages of many hunter-gatherer people today. 

This research overturns the popular view that all human speech sounds were present when human beings evolved around 300,000 years ago. "The set of speech sounds we use has not necessarily remained stable since the appearance of human beings, but rather the huge variety of speech sounds that we find today is the product of a complex interplay of things like biological change and cultural evolution," said Steven Moran, a member of the research team. 

At just seven years old, Angelina Tsuboi discovered her passion for innovation. It all began with a simple game she programmed in her Los Angeles public school's Grade 2class. Today , at18, the Grade 12 student's initial curiosity has evolved into a deep-seated desire to use technology to decode (解码) real-world problems. 

In 2021, she co-developed Megaphone, one of her first apps, to tackle unanswered post-class questions and poor communication about events and announcements. Her problem-solving ability kept building from there. 

When she took online CPR classes at the start of the pandemic, she figured it couldn't be just her who was struggling with the steps. So she created an app called CPR Buddy ― a winner in the 2022 Apple Swift Challenge ― which guides users through CPR using vibrations (震动) to regulate breath. After winning the award, Angelina presented her work to Apple CEO Tim Cook, a highlight in her young career, but one she didn't lose her cool over. "There's no point putting people on a pedestal (神坛)," she says. 

The next year, Angelina built an app called Lilac, designed to assist nonEnglish-speaking single parents with resources for housing, job opportunities and translation support. She was inspired by her own experiences as a child of a single mother who immigrated to the US. 

When Angelina decided to pursue pilot training at the age of 16, she was struck by how difficult it was to find financial support, which encouraged her to create yet another app, Pilot Fast Track, which helps those longing to be pilots find scholarships for flight training. 

Looking to the future, besides applying to colleges with great labs, Angelina is exploring the field of aerospace cybersecurity and mechatronics ― combining computer science, electrical engineering and mechanical engineering. 

"There's not enough optimism in the world," she says. "I have also been in situations in my life where I've lost a lot of hope. But in the end, it is a mindset, and there are ways in any situation you're in to make it somewhat better. "
