    Suppose you're in a rush, felling tired, not paying attention to your screen, and you send an email that could get you in trouble.

    Realisation will probably set in seconds after you've clicked “send”. You freeze in horrors and burn with shame.

    What to do? Here are four common email accidents, and how to recover.

    Clicking “send” too soon

    Don't waste your time trying to find out if the receivers has read it yet. Write another email as swiftly as you can and send it with a brief explaining that this is the correct version and the previous version should be ignored.

    Writing the wrong name

    The sooner you notice, the better. Respond quickly and briefly, apologizing for your mistake. Keep the tone measured: don't handle it too lightly, as people can be offered, especially if your error suggests a misunderstanding of their culture(i.e. incorrect ordering of Chinese names).

    Clicking “reply all” unintentionally

    You accidentally reveal(透露)to entire company what menu choices you would prefer at the staff Christmas dinner, or what holiday you'd like to take. In this instance, the best solution is to send a quick, light-hearted apology to explain your awkwardness. But it can quickly rise to something worse, when everyone starts hitting “reply all” to join in a long and unpleasant conversation. In this instance, step away from your keyboard to allow everyone to calm down.

    Sending an offensive message to its subject

    The most awkward email mistake is usually committed in anger. You write an unkind message about someone, intending to send it to a friend, but accidentally send it to the person you're discussing. In that case, ask to speak in person as soon as possible and say sorry. Explain your frustrations calmly and sensibly—see it as an opportunity to clear up any difficulties you may have with this person.

    Technology offers conveniences such as opening the garage door from your car or changing the television station without touching the TV.

    Now one American company is offering its employees a new convenience: a microchip implanted in their hands. Employees who have these chips can do all kinds of things just by waving their hands.Three Square Market is offering to implant microchips in all of their employees for free.Each chip costs $300 and Three Square Market will pay for the chip.Employees can volunteer to have the chips implanted in their hands.About 50 out of 80 employees have chosen to do so.The president of the company,his wife and their children are also getting chips implanted in their hands.

    The chip is about the size of a grain of rice.Implanting the chip only takes about a second and is said to hurt only very briefly.The chips go under the skin between the thumb and forefinger.With a chip in the hand,a person can enter the office building,buy food,sign into computers and more,simply by waving that hand near a scanner.The chips will he also used to identify employees.Employees who want convenience,but do not want to have a microchip implanted under their skin,can wear a wristband（腕带）or a ring with a chip instead.They can perform the same tasks with a wave of their hands as if they had an implanted chip.

    Three Square Market is the first company in the United States to offer to implant chips in its employees.Epicenter,a company in Sweden,has been implanting chips in its employees for a while.

    Three Square Market says the chip cannot track the employees.The company says scanners can read the chips only when they are within a few inches of them.“The chips protect against identity theft,similar to credit cards.”The U.S. Food and Drug Administration approved the chips back in 2004,so they should be safe for humans,according to the company.

    In the future,people with the chips may be able to do more with them,even outside the office.Todd Westby is Chief Executive Officer of Three Square Market.He says,“Eventually,this technology will become standardized allowing you to use this as your passport,public transit,all purchasing opportunities,etc.”

    The Winter Olympics are also called The White Olympics. At this time, many colorful stamps are published to mark the great Games. The first stamps marking the opening came out on January 25th,1932 in the United States for the 3rd White Olympics. From then on, publishing stamps during the White Olympics became a rule. During the 4th Winter Olympics, a group of stamps were published in Germany in November 1936. The five rings of Olympics were drawn on the front of sportswear. It was the first time that the rings appeared on the stamps of the White Olympics.

    In the 1950's, stamps of this kind became more colorful. When the White Olympics came, the host countries as well as the non-host(非主办方)countries published stamps to mark those Games. China also published four stamps in February 1980, when the Chinese sportsmen began to take part in the White Olympics.

    Japan is the only Asian country that has ever held the White Olympics. Altogether 14,500 million stamps were sold to raise money for this sports meeting.

    Different kinds of sports were drawn on these small stamps. People can enjoy the beauty of the wonderful movements of some sportsmen.

    How much weight a baby gains during its first month could determine its IQ, as a new research suggests. The study found that children who gain more weight, and whose heads grow quickly during the first month of life, tend to have a higher IQ when they start school.

    Researchers at the University of Adelaide, in Australia^ studied 13,800 children who were born at full-term. They found that those who put on 40% of their birth weight in the first four weeks had an IQ 1.5 points higher than those who only put on 15% of their birth weight. Those who experienced the biggest growth in head circumference (头围) also had the highest IQs by the age of six.

“Head circumference is an indicator of brain volume, so a greater increase in head circumference in a newly-born baby suggests more rapid brain growth,” says the led author of the study, Dr. Lisa Smithers.

    She added, “Overall, newly-born children who grew faster in the first four weeks had higher IQ scores later in life. Those children who gained the most weight scored especially high on verbal (言语) IQ at age 6. This may be because the neural (神经的) structures for verbal IQ develop earlier in life, which means the rapid weight gain during the first month could be having a direct cognitive benefit for the children.”

    Previous studies have shown the association between early postnatal (产后的) diet and IQ, but this is the first study of its kind to focus on the IQ benefits of rapid weight gain in the first month of life. Dr. Smithers says the study further highlights the need for successful feeding of newly-born babies. “We know that many mothers have difficulty establishing breastfeeding in the first week of their babies' life,” Dr. Smithers said.

    “The findings of our study suggest that if babies are having feeding problems, there needs to be early intervention (干预) in the management of that feeding.”

    During the first decade of the 21st century, a popular and new word has come into our vocabulary. That word is Facebook. This is the most popular social networking website on the Internet. There are about 350 million active users on this website. The main idea of Facebook is that you can keep in touch with all your friends around the world who has Facebook. In the 350 million users on Facebook, 67% of them are between the ages of 13-25. More than 35 million users update their status every day. 2.5 billion Photos are added each month.

    The highest age groups who use Facebook are teenagers. Most of them keep the website running whenever they are using the computer and general teens nowadays are always on the computer, if they aren't in school or when they aren't asleep. I feel that teens should focus on their schoolwork or be socializing with their friends in person or exercising. Facebook is just changing the new generation of youngsters completely because the teenage life is one of the most important stages of life and wasting it on Facebook is not encouraging this in any way. It is also a complete distraction (分心) to their mind, for they would turn to Facebook just to check if there was anything updated among their friends.

    Remember back in the good old days, when teens would do their homework handwritten, play sports and hang out with friends. Today, most teens would only speak to their friends on Facebook, while we can see them battling obesity as they stare at their friend's message on their wall. In summary, teens don't have a life because they are on Facebook 24/7, except for those who don t use Facebook or occasionally do.

    Facebook is also where people can see the conflicts among their friends, virtual arguments, relationship status and updates, who is in whose 'top friends, and so on. You can join groups, post pictures and videos, play games, and invite friends to parties. Mainly, all this would just disturb people into living life to its fullest.

Many on the Mountain

We often see people waiting in lines at supermarkets, theatres and amusement parks. Surprisingly, some people even have to wait in line at the summit (顶峰) of Qomolangma in the Himalayas. 

The best time to climb the Himalayas is during the months of April and May, as well as some days in September and October. "In these periods of recent years, the path contains rocks and deep crack from melting ice due to the warm weather, which make expeditions up the mountain more dangerous," said Apa, an experienced Nepalese guide. During this year's climbing season, crowds of climbers became stuck in a long line near the summit. The line is above the mountain's highest campsite—about 8,000 meters above sea level. 

However, most people can only spend a few minutes at the summit without extra oxygen supplies. Twenty-one mountaineers have died in the Himalayan mountains so far this year, according to Gripped, a magazine dedicated to mountain climbing. Eleven of these climbers died on Qomolangma. 

This death count marks a four-year high. Overcrowding, inexperience and poor weather have been the most common causes of death, USA Today reported. 

After these tragedies, one question remains: Why do so many people risk their lives to climb the mountain? The answer differs from climber to climber. Studies suggest that people who take risks tend to perceive themselves differently than people who avoid risky activities. But for adventurers who are drawn to the Himalayas, reaching the summit of Qomolangma is a lifelong dream, according to Discovery News. 

"Qomolangma is like a light to bugs that attracts people once they hear about it. It represents the ultimate for many people," US mountaineer Alan Arnette said. Technological advances have also encouraged more people to climb the mountain. People can get high-tech safety equipment more easily than before. And with the internet, climbers know better than ever about how to reach the summit safely, Yahoo Travel noted.
