Neither rain nor snow nor the dark of night can separate Tennessee postal carrier “Mailman Mike” from his 4-and-a-half-year-old friend Carter Lawson – or keep them from their appointments.

    For the past nine months, the two have teamed up every day in the preschooler's Knoxville neighborhood for a few minutes of delivering mail together and chatting with fellow neighbors. Lawson wants to be a mail carrier when he grows up, and in an inspiring story, his mom told us how mailman Mike Crenshaw has been a role model to her son. “Anyone could just be like 'Go away, kid', but Mike has really gone out of his way to talk with Carter,” said Cassie Lawson of the United States Postal Service carrier. Little Carter even got his own uniform to match Mike's. “It's been really cute. I just couldn't believe he got a full mailman's costume,” the postal service employee said.

    “Every letter carrier has stops he looks forward to and this is the one I look forward to every day,” said Mike. “He's the end of my day, and the best part of my day. Not because it's the end, but because he's such a cute little guy.”

    The man and the little boy's connection isn't a surprise to Fredric Rolando, president of the National Association of Letter Carriers. “Kids respond to mailmen because letter carriers are a friendly, uniformed part of the neighborhood who bring something to their house every day, and are someone they come to recognize and trust,” Rolando said. “It's the same for the elderly, but in addition, letter carriers may be the only person they communicate with all day.”

Discovery's astronauts arrived to an exciting celebration Wednesday as nearly 700 people crowded an airplane storage place, waving flags and holding signs that read: “Welcome Home, Astronauts!”

    The seven-person team returned to Earth on Tuesday after being the first to take a space shuttle into orbit since the Columbia disaster（灾难）of 2003. 

    “In the last two and a half years, we have been through the very worst that manned space flight can bring us, and over the past two weeks we have seen the very best,” NASA Administrator Michael Griffin told the astronauts and their families and fans Wednesday. 

    The crowd waved American flags for the U.S. astronauts and Japanese flags for crew member Soichi Noguchi, one of the spacewalkers. 

    “As a rookie（新手）astronaut, I could not ask for more,” Noguchi said, “We had three spacewalks, two extra days in space and one great team.” 

    While the homecoming has been filled with excitement for what mission controllers declared a “truly spectacular test flight”, uncertainty remains for the future of the shuttle program. 

    Shortly after Discovery rose up into space July 26, a nearly 1-pound large piece of foam insulation（泡沫绝缘材料）fell from the fuel tank-the very thing that was supposed to have been fixed after Columbia exploded. The foam missed Discovery, but NASA grounded all shuttle flights until engineers fix the problem.

    NASA ground crews examined Discovery after its return from orbit and found it in good condition, an official said Wednesday at NASA‟s Dryden Flight Research Center at Edwards Air Force Base in California. 

    Technicians counted 101 dings and divots, including 20 that were larger than 1 inch. Schaaf Dean, landing support group chief, said the numbers were similar to the results of other shuttle, post-landing examinations. 

A beginning examination of the shuttle's thermal（热的）blanket showed it remained undamaged during re-en-try into the Earth's air.(Agencies)

    Jack Ma, whose Chinese name is Ma Yun, became the richest man in China, when the company he founded floated on the stock market last year with a value of around ￡140 billion. Here are some interesting stories about him.

    ⒈"Beer" was the first word that Jack Ma searched for on the Internet

    In 1995 Ma made his first trip to the US and used the Internet for the first time. After searching for "beer" and then "China", he saw that no results came up relating to China. He decided to set up a Chinese website一the seed for Alibaba had been sown.

    ⒉Jack Ma applied to study at Harvard 10 times and was rejected (拒绝) each time

Ma failed the entry exams for colleges in China three times and was also rejected for many jobs in China, including one at KFC. He was turned down by the Harvard 10 times after applying.

    ⒊Jack Ma learnt English by giving tourists free guides一every day for nine years.

    Limited resources meant it was difficult to learn English when Ma was young. However, he found that he could learn the language by giving tourists free tours around his hometown of Hangzhou一something that he did during his teenage years every morning for nine years. He found everything they said and did was so different from what he had been taught at school and by his parents, which opened his mind.

    ⒋Jack Ma named his company Alibaba because it's a globally known story

Ma simply wanted his company to have a global and interesting name, and realised that Alibaba is a story known across the world and it begins with A, appearing top of lists.

    The company was founded in 1999 and since then has grown from 15 employees to more than 30,000. Ma hopes to keep expanding Alibaba outside of China.

    Most of the time, people wear hats to protect themselves from harsh weather conditions. Hats are also worn to show politeness and as signs of social position. But nowadays, hats, especially women's hats, are much more than that. More exactly, hats have changed into fashion and style symbols by many movie stars. What's more, people now consider many different features when choosing even a simple hat. Many designers point out that, when choosing the right hat, it's important to consider the color of your skin as well as your hair, your height, and the shape of your face.

    First of all, the color of the hat should match the color of your skin and hair. For instance, black hats should be avoided if you are dark skinned. If a purple hat is placed on top of red hair, one will look as attractive as a summer flower. Second, the height of the hat is also an important point. Tall women should not go for hats with tall crowns, just as short women should choose hats with upturned brims to give the look of height. Third, and most importantly, the shape of the face decides the kind of hat one should pick. A small, gentle hat that fits the head looks good on a small face. However, women with big, round faces should choose a different style.

As the saying goes, "Fine feathers make fine birds." A good hat can not only help your dress but also support your features, so why not choose the best possible one next time you want to be in public?

When you are online, you can be anyone or anything. You can create your own image and a new personality. These digital identities are known as avatars(化身).

The first simple 2D avatars appeared in role-playing computer games in the 1980s. Yet, very few people knew that future avatars would have such a wide variety of forms and uses. By the late 1990s, they had been used in web chats.

When people started creating their own avatars, they discovered that they were going to have the power to create new identities that did not look or act like their real selves at all. They could dress their avatars in fancy clothes, or they could try being someone of the opposite sex. When Internet users realized that their avatars would be seen by many people, not just their friends, they started having more than one avatar. Avatars let you express yourself and they give you lots of room for creativity.

Of course, the avatar you choose says a lot about your personality. If your blog avatar is a picture of a cute cat, your message is "like relaxing and having fun". Well-known cartoon characters or laughing monkeys say "I'm a really funny person". Most people create avatars that have similar features to their personalities and that look more or less like them and act like them. However, people obviously make their avatars look better than they do in real life.

Nowadays, avatars are everywhere and very useful. In most web chats, people choose an avatar from a selection of ready-made images or create their own images. You can also use avatars that move around and talk when you type in your message. 

Despite the advantages of avatars, the use of avatars has also caused a few concerns. Some users worry that they are spending so much time in virtual worlds that they are becoming afraid of meeting people in the real world. The use of several avatars can also be a risk, as people can use avatars to cheat others online.

My grandfather was born in a small town in Italy. He would wake up at four in the morning every day to work on the farm. Although he was a great student in school, he only went up to Grade 3 because he was required to help with the family farm. 

Later, my grandfather used his own hard-earned savings—the small amount was all he had—to travel to Canada. He was alone in a new country, not knowing anyone and not speaking English or French. At a farm, the owner quickly saw what a hard-working young man my grandfather was, so he paid my grandfather a much higher salary. Although the owner was very nice to him and treated him like family, he was not satisfied. He dreamed of being more successful, of better career advancements. 

One day, he got an offer to work in the construction industry. My grandfather, a newly immigrated young famer, who was eager to move up in the world, caught this opportunity and prospered( 发达 ) through hard work. Around 1967, however, he become overwhelmed(不知所措的)with stress, sleepless nights and anxiety from the business. He also had two young daughters to take care of and my grandmother was in the hospital at the time. The combined stress and anxiety unfortunately drove him into a major depression. During a medical check-up, his doctor warned him about his health. He knew it was time for him to make a change and decided to sell his shares in the company. 

He then began a smaller business of his own, which resulted in less stress and more time with family. Had he chosen not to quit his former job, he might have been a billionaire today. My grandfather will turn 95 in October; even at this ripe old age, he is still strong, well and high-spirited. Looking at his story as a life example, he teaches us to work hard, but at the same time not to forget to enjoy life and have a good sense of humour about it all. 

Work is important, sure, but there is much more to life than just that. Overall, this is the ultimate key to happiness.
