Have you ever lost your direction? Then you might find satellite navigation(satnav) systems(卫星定位系统) helpful.

    A satnav system uses groups of satellites. They send information to a receiver(接收器), such as your smartphone. Then they can find where you are.

The earliest satnav system is the Global Positioning System(GPS) of the United States. The US has put 24 satellites into space to make sure GPS can locate(定位) a person correctly and globally. Likewise, Russia's GLONASS and European Union's Galileo can also work globally.

    But China is catching up, building its own BeiDou Navigation Satellite System. BeiDou is China's homegrown satnav system, reported Xinhua. It was set up in 2000, when China sent BeiDou's first navigation experiment satellite into space. With it, China became the third country to build a satnav system after the US and Russia.

    BeiDou can find you wherever you are. It helps you go faster by finding shortcuts(捷径) and using correct directions. When you are in trouble and call the police, they will know exactly where you are if you have a cellphone that uses BeiDou.

    Today, there are more than 20 BeiDou satellites above our heads. And the system is able to offer open services to the Asia-Pacific region(亚太地区).

    In November, China plans to send more BeiDou-3 satellites into space. BeiDou-3's position accuracy(准确度) is less than five meters, Ran Chengqi, a senior designer of the satellite navigation system, told China Daily.

    By 2020, BeiDou is planned to have 35 satellites and begin serving globally, reported Xinhua.

There are no full court games during Family Shootaround hours. All participants must sign in at the front desk and wear a wristband during the play.

    I will never forget the days when I met with my classmates. Early in the morning of our first school day, our professor introduced himself and challenged us to get to know someone we didn't know yet. I stood up look around when a gentle hand touched my shoulder. I turned round to find a wrinkled, little old lady beaming up at me with a smile that lit up her entire being.

    She said, “Hi handsome. My name is Rose. Can I give you a hug?”

    I laughed and enthusiastically responded, “Of course you may!” and she gave me a giant squeeze.

    “Why are you in college at such a young, innocent age?” I asked.

    She jokingly replied, “I'm here to meet a rich husband, get married, and have a couple of kids…”

    “No seriously,” I asked. I was curious what may have motivated her to be taking on this challenge at her age.

    “I always dreamed of having a college education and now I'm getting one!” she told me.

    After class we shared a chocolate milkshake. We became instant friends. Every day we would leave class together and talk nonstop. I was always mesmerized（迷住）listening to this “time machine” as she shared her wisdom and experience with me.

    At the end of the semester we invited Rose to speak at our football banquet. I'll never forget what she taught us.

    “There is only one secret to staying young. You've got to have a dream. When you lose your dreams, you die. We have so many people walking round who are dead and don't even know it! There is a huge difference between growing older and growing up. If I am eighty-seven years old and stay in bed for a year and never do anything I will turn eighty-eight. Anybody can grow older. That doesn't take any talent of ability. The idea is to grow up by always finding opportunity in change. Have no regrets. The elderly usually don't have regrets for what we did, but rather for things we did not do. The only people who fear death are those with regrets.”

    She concluded her speech by courageously singing The Rose. She challenged each of us to study the lyrics and live them out in our daily lives.

    One Moore Elementary school teacher is showing students the importance of communication through “shout-outs”. Third Grade Moore Elementary teacher Lindsey Winders said a shout-out is a compliment（称赞）that students can say or write down. “Like, 'hey I noticed you doing a really great job solving your math facts yesterday. I wanted to make sure you know that I saw you do that,” Winders said.

    Winders said she makes sure she is giving shout-outs to her students every day. “I might write them a sticky note, or write them a quick little note in their plans. I might just say it to them on their way into the classroom or on their way out of the classroom, but most importantly I try to do it every day,” Winders said.

    In addition to the compliments, Winders has the students greet each other every morning during morning meeting. She will have students give examples to the class of how to communicate in different settings. Third grade student Nayelli Moranchel said she has given at least six shout outs this year. “It makes me happy, because they always write something back,” Moranchel said.

    Recently, Winders took it one step further and wrote a personalized note on each of her students' desk. “In our classroom, sometimes it can be challenging for me to give a compliment or a shout out to each and every one of them in a way that feels equal and valuable at the same time. So I thought what's a better way to be able to do that than leaving a note on their desk that can stay for as long as they want it.” Winders said.

    Winders said it is encouraging when she sees her students copy the act, and give each other compliments without her guidance.

    It's time for those who are about to graduate to look for jobs since graduation season is drawing near. Competition is tough, so job seekers must carefully consider their personal choices. Whatever we are wearing, our family and friends may accept us, but the workplace may not.

    A high school newspaper editor said it is unfair for companies to discourage visible tattoos (文身), nose rings, or certain dress styles. It is true you can't judge a book by its cover, yet people do "cover" themselves in order to convey (传递) certain messages. What we wear, including tattoos and nose rings, is an expression of who we are. Just as people convey messages about themselves with their appearances, so do companies. Dress standards exist in the business world for a number of reasons, but the main concern is often about what customers accept.

    Others may say how to dress is a matter of personal freedom, but for businesses it is more about whether to make or lose money. Most employers do care about the personal appearances of their employees, because those people represent the companies to their customers.

    As a hiring manager I am paid to choose the people who would make the best impression on our customers. There are plenty of well-qualified candidates, so it is not wrong to reject someone who might disappoint my customers. Even though I am open-minded, I can't expect all our customers are.

    There is nobody to blame but yourself if your set of choices does not match that of your preferred employer. No company should have to change to satisfy a candidate simply because he or she is unwilling to respect its standards, as long as its standards are legal.

    Babies born in summer are more likely to become short-sighted in late life, a study has shown.

    As many as a quarter of all cases of short-sightedness are caused by too great an exposure to sunlight in the first weeks of life, say eye experts.

    They are advising all parents to put sunglasses on their babies during the first weeks.

    Scientists had already established that over-exposure to sunlight caused shortsightedness in animals.

    Researchers who compared the months in which babies were born with whether they needed glasses later on say the principle also applies to humans.

    A study of almost 300, 000 young adults-the largest of its kind-showed that those born in June and July had a 25 per cent greater chance of becoming severely short-sighted than those born in December or January.

    Research leader Professor Michael Belkin, of Tel Aviv University, said it was because prolonged illumination(光照) causes the eyeball to lengthen-causing short-sightedness.

    Hence the more light a newborn is exposed to, the more the eyeball lengthens and the worse the short-sightedness will be.

    The mechanism which lengthens the eyeball is associated with levels of melatonin(褪黑激素), a pigment (色素) which protects the skin against harmful rays of the sun.

    In young babies not enough melatonin is released as protection, meaning they are more vulnerable to sunburn and changes to eyeball shape.

    Sight expert Professor Daniel O'Leary, of Anglia Ruskin University in Cambridge, said "At the moment we don't know the precise cause of why light exposure affects sight, but the evidence seems to prove that it is one of the reasons for people becoming shortsighted."
