    Do you love Beats headphones, True Religion jeans, and UGG shoes? These are some of the most popular brands (牌子) around. They are also expensive. But some experts say they are not much better than cheaper brands.

    For example, Jim Wilcox works for Consumer Reports. He tested all kinds of headphones. He says that $80 Koss Pro headphones provide basically the same quality (质量) and comfort as Beats. So why do people pay twice or even 10 times as much for the hottest brands?

    Experts say it's because fashionable, expensive brands send a message. Brands say “I belong” or “I can afford it.”

    Some people think that expensive brand names are worth the price. They say that some designer clothes really are top quality and that they last longer than cheaper brands. Some teenagers choose to wear popular brands because these brands make them feel good about themselves.

    Alexandra Allam, 17, likes to buy brand-name products. “I'd rather spend the extra money to get something I know I'll be satisfied with,” she says. Her friend Emmy Swan agrees, saying “As long as you can afford it, it seems reasonable to buy what you want.” But not all teenagers agree. “Spending hundreds of dollars for designer sunglasses is stupid and unreasonable,” says Daniel Steinbrecher, 16. “It's fake (假的) happiness.”

    People who are against wearing expensive brand names say that many designer brands aren't any better. “It's wasteful to buy things just because they are popular,” says Edmund Williams, 15. “You'll feel better if you buy things because you like them. If you have extra money to spend, it would be better to give it to people in need.”

    Antarctica, with its seemingly endless icy beauty, is one place where one look is worth a thousand words. My own dream to see it came true last January when I joined the sixth exploration crew(考查队) of the China National Marine Bureau. We spent 10 days connecting flights to reach our goal, but finally arrived at the Great Wall Station on Antarctica on the eve of Chinese New Year.

    There are only two seasons in Antarctica: winter and summer. You get polar nights in winter and polar days in summer. Day is longer than night in summer, and the temperature often reaches below zero. Luckily, there are no snowstorms in summer, which makes it the best season to travel. What I imagined before starting for Antarctica was a world of ice, storms, endless cold and loneliness. When I stopped on Antarctica for the first time, however, I saw rich, energetic and beautiful scenery that was beyond anything I had imagined.

    We only spent 11 days at the South Pole, but every minute was spent taking pictures and losing our heart to the wonderland. Beauty enveloped us as we watched the world around us. The mountains, oceans, ice, snow, sky, earth and people all seemed to have their own stories.

    Rocks from Antarctica are considered valuable. Unfortunately, I didn't bring one back. However, my heavy bags full of films are certainly worth that. It is in these pictures that the true Antarctica comes alive.

    When my vision-challenged daughter was 3, and I was pregnant with my second child, we got her glasses. It was a long process involving many different opticians (配镜师)over the course of a year, because of my daughter's overwhelming desire to scream and fly into a temper any time we tried to have her eyes examined. The fourth optician was amazing while my daughter didn't cooperate, she performed various miracles and managed what she called a “best guess” at her prescription.

    “Start with this,” she said. “When she realizes she can see better, bring her back, and we can try for something more accurate.”

    I didn't want to pay $300 for glasses that might be replaced in a month's time, so I decided to bring her straight to a Walmart optical. Things were going on well, until the optician needed to take an additional measurement, which would involve holding a ruler up to her eyes and measuring the distance between the outer corner of one eye and the inner corner of the other.

    “Are you sure you need the measurement?” I asked. “She's really not cooperative when it comes to the eye-testing stuff.”

    “We definitely need to have it, we can't fill her prescription without it.” the optician said.

    But my daughter would not let the optician anywhere near her face with the small plastic ruler. She started yelling and crying, and we took her off to the side and promised we'd get ice cream afterward if she let the nice lady hold the ruler near her nose! The optician gave us the ruler, thinking we would have an easier time, but when my daughter knew we needed to hold the ruler near her face, which, in toddler logic, meant a life-or-death situation, she prevented us from getting anywhere near her.

    Finally, my husband and I agreed that one of us would have to hold her down and the other would take the measurement. I sat on the floor trying to hold her head still while my husband tried to get an accurate reading on that stupid ruler. Despite her struggle and scream, we finally got it. My daughter stopped crying three seconds later and went back to play as if nothing had happened.

    There is no version of this story where I feel comfortable us even if it was for her own good. I felt awful wondering, if magically know what to say to get her cooperation? The weeks spent with a special book about wearing glasses, telling her how great glasses were... I could feel tears welling up and I thought, “I can't cry. I'm sitting on the floor of a Walmart optical centre. I can't cry here.”

    And there it was the final thing I could not bear. It w already reduced me to sitting on the floor of a Walmart optical p toddler down to press a ruler against her face and do it for the packed Saturday audience of all the Walmart checkout counters. I cried. Big, shoulder-shaking sobs. Sitting right there on the floor of a Walmart, behind the optical counter.

    Five days later, the Walmart optical centre called. They said my daughter's glasses were ready for pickup and I should schedule an appointment with the optician so that we can have them properly fitted. I said I'd be picking up the glasses alone and we would do the fitting another day. She insisted that the fitting was crucial, to which I replied, “I don't know if you were working last Saturday, but my daughter is really not cooperating on this whole glasses thing. I'd prefer to just pick them up.” Silence. Then she said, “I was there last Saturday, I remember you. Absolutely, you can pick them up any time.”

    After shopping for deals in stores on "Black Friday", or online on "Cyber Monday", Americans and people worldwide are preparing for newly popular "Giving Tuesday". Starting in 2012, now the global event that is celebrated annually on the Tuesday after Thanksgiving is the brainchild of 92nd Street Y, a cultural center in New York City and United Nations Foundation.

    As the name indicates, Giving Tuesday is meant to restart the charitable season and therefore observed by raising funds for local nonprofits and schools, organizing food and clothing drives, and conducting random acts of kindness. In 2015, 700, 000 people from 71 countries came together to donate $116.7 million in cash. An additional $1.08 million was spent on gifts.

    While the easiest way to participate is by donating to your favorite charity, this day can be celebrated in many other ways too. You can give back by volunteering at your local shelter or food bank, or even by donating blood. If all else fails, a purchase from the growing number of organizations that give a portion of their sales to charity will do the trick.

    But perhaps the best way to celebrate the day is by helping those nearest and dearest to you. Assist a family member with a simple chore like folding laundry, cooking dinner, or even reading to a younger sibling. No matter what you do, be sure to share you good deed on social media and inspire others to celebrate Giving Tuesday as well!

A donation letter is what you write to a person you expect, who will give away some of his money to support your good cause. Good as the cause may be, it is hard to make a person part with his hard-earned money. It takes some really great writing skills to write such a letter.

The donation letter for charity isn't exactly a formal letter for business communication. You need to take a casual tone. Make sure that you know the name of the recipient (收信人) to sound more like a friendly gesture. The language too should not be extremely serious and should be slightly informal, which can make your recipient willing to believe you.

Make sure that you include all the details regarding your program, your funds required, and your plan in the letter. The most important thing is to mention how someone stands to benefit because of the recipient's contribution. Talk about how many lives your charity fund has been able to change and how many more you wish to change further. This may touch the reader and talk him into making a donation towards your cause. Include the amount which you expect the recipient to donate, within your letter.

A typical donation letter is often divided into four paragraphs. The first paragraph will be an introduction to your organization, like what you do, how long you have been running, and your achievements. The second paragraph will give more details regarding your current goals that you're trying to reach. In the third paragraph you use a more direct method here, asking politely for any help. Keep it short and clear. The final paragraph is your conclusion, where you tell exactly how the help received would be put into good use. Add a "thank you" for any and all help received.
