It could happen just about any time you step out in public. You get onto an almost-empty bus, but the next passenger in decides to ignore dozens of empty seats to sit right next to you. While you're waiting in line at a supermarket, the next customer insists on standing only two inches behind you and shouting into his cell-phone. You go into a public restroom, and the next person to enter decides to use the next stall. Transgressions(冒犯) like these don't just make us feel uncomfortable; we often feel anxious, alarmed; and violated(被侵犯的). It is the attack of the personal-space invaders.

    In any society, shared definitions of personal space govern how we interact with other people. People living in densely(密集地) populated cities like Mumbai, Beijing, or Mexico City tend to require less personal space than people living in sparsely(稀少地) populated places within the country. In America, New Yorkers often have smaller requirements than residents of western states, like Montana, Shenandoah and Wyoming. Because everyone has different standards, gestures that are innocent in one place can be interpreted as opposite in another, especially in Britain.

    As the British etiquette(礼仪) website Debrett puts it, as a British person, somebody standing too close may make you "focus less on what somebody is saying than on how close they are to you". Simple acts like putting an arm around someone you don't know may seem friendly in China, but they can make us very uncomfortable. People from many European countries such as France and Spain kiss each other on the cheek when they meet, yet to British person, this seems too friendly and "touch-freely". The website explains! "The British are not backslappers(拍人后背的人) and generally do not show affection in public".

    Are British people unfriendly? Far from it. The website adds that they are not as "stand-offish and aloof' as they may seem, but very friendly and helpful to foreigners. However, remember not to be too close. If you are going to come closer than an arm's length, please let them know.

    The year is 2094. It has been announced that a comet (彗星) is heading towards the Earth. Most of it will miss our planet, but two pieces will probably hit the southern half of the Earth.

    On 17 July, a piece four kilometers wide enters the Earth's atmosphere with a massive explosion. About half of the piece is destroyed, but the remaining part hits the South Atlantic at 200 times the speed of sound. The sea boils and a huge hole is made in the sea bed.  Huge waves are created and spread outwards from the hole. The wall of water, a kilometer high, rushes towards southern Africa at 800 kilometers an hour. Cities on the African coast are totally destroyed and millions of people are drowned.

    Before the waves reach South America, the second piece of the comet lands in Argentina. Earthquakes and volcanoes are set off in the Andes Mountains. The shock waves move north into California and all around the Pacific Ocean. The cities of Los Angeles, San Francisco and Tokyo are completely destroyed by earthquakes. Millions of people in the southern half of the earth are already dead, but the north won't escape for long. Because of the explosions, the sun is hidden by clouds of dust, temperatures around the world fall to almost zero. Crops are ruined. The sun won't be seen again for many years. Wars break out as countries fight for food. A year later, no more than 10 million people remain alive.

    Could it really happen? In fact, it has already happened more than once in the history of the Earth. The dinosaurs were on the Earth for over 160 million years. Then 65 million years ago they suddenly disappeared. Many scientists believe that the Earth was hit by a piece of object in space. The dinosaurs couldn't live through the cold climate that followed and they died out. Will we meet the same end?

    Smoking is harmful. But as soon as you quit the habit, everything will be OK, right? Wrong.

    New research has found that even if you give up smoking, the damage it has done to your genes will stay there for a much longer time. In the research, a team of US scientists studied the blood of 16,000 people. Among them, some were smokers, some used to smoke, and the rest were non-smokers. Scientists compared their genes and found that more than 7,000 genes of smokers had changed--a number that is one-third of known human genes.

    According to NBC News, both heart disease and cancer are caused by genetic changes. Some people may have had the changes when they were born, but most people get them in their day-to-day lives while doing things like smoking.

    When you stop smoking, a lot of these genes will return to normal within five years.

This means your body is trying to heal (治愈) itself of the harmful effects of smoking. But the changes in some of the genes stay for longer. They can stay for as long as 30 years, It's almost like leaving a footprint on wet cement (水泥)—-it will always be there, even when you've walked away and when the cement becomes dry.

    Although the study results may make people unhappy, there is a bright side: the findings could help scientists invent medicine to treat genetic damage caused by smoking or find ways to tell which people have heart disease or cancer risks.

Let Kids with Cancer Be Kids Again!

    We care about the needs of kids with cancer

    Camp quality originated in 1983 in Sydney, Australia. The camp was created to give kids with cancer and their family a place to interact with other children and have an extraordinary summer. Activities are designed with kids in mind such as swimming, fishing, arts and crafts, and even the beloved campfires.

    Companions and volunteers

    The safety of campers and staff(员工)is of top priority to Camp Quality Arkansas. Each staff member is required to attend a training session. Within these sessions, each potential staff member gets to know the program and then a decision is made to decide whether he or she will fit best in the camp.

    "In all of our volunteers we look for adults who can lead with their own actions and have a child-like spirit. This ability to have fun is essential to the success of the camp. While the companions work directly with the campers, we are always on the lookout for volunteers to fill the positions of RNs, certified lifeguards, photographers, and kitchen staff," said Amber Dovel, volunteer coordinators at Camp Quality Arkansas.

    A unique function of the camp is that for each kid a companion is assigned. A companion is a reminder of "hope, courage, and happiness, not only during the week of camp, but all year round," according to the official website.

    No one knows how much money Dr. Lyle Tullis gave away to students. I was his colleague for nearly a decade and I never stopped being amazed at his generosity. Our college has a program of providing cross-cultural experiences for students. Lots of students take advantage of summer experiences oversea. I discovered that no group left for overseas without some of its members receiving financial help from Dr. Tullis.

    It wasn't that he made a lot of money. For one thing, he taught in a church-run school. There, his salary (薪水) was half of what those people earned in a tax-supported school.

    Other colleagues occasionally complained about the low pay. Not Lyle Tullis. Occasionally some professors would leave our campus for a better-paid position. They told me they did so because, with better pay, they could provide for their families.

    The size of Lyle Tullis' paycheck never seemed to be the most important thing to him. I realized that one day when I was thanking him for helping a student, his eyes shone as he said to me, "I've got so much money that I don't know what to do with it. So, I just give it away."

    Most people wouldn't have thought that way. Dr. Tullis drove one of the oldest cars on campus. It was even older than almost any of the students' cars. His home, while comfortable, was not fancy at all. But Lyle Tullis lived with the feeling that he had so much money that he needed to give it away.

    He was one of the favorite on campus. Cynics (愤世嫉俗) might say he bought fame. But they would misunderstand. Lyle wanted to devote his life, all of it, to helping others.

    Austin Perine, a four-year-old boy, discovered that sympathy for the less fortunate can produce superhuman results.

    Once Austin's father, TJAustin, took Austin to the Firehouse Ministries, a local shelter that provides housing, food, and other services for homeless men. As they drove by the redbrick building, they saw a group of 25 homeless men standing on the street corner. "Dad, they look sad," Austin said. "Can we take them some food and make them smile?"

    That day, Austin used his allowance to buy each man a Burger King sandwich and handed the food out himself.

    Seeing what their presence meant to the men at the ministry, Austin and TJ returned the next week. After he returned every week for five weeks, word of Austin's acts of kindness spread through social media and national news outlets. Burger King jumped aboard, agreeing to donate $1,000 a month for an entire year toward the cause. Soon, churches and shelters across the country began inviting Austin to come and distribute food in other poor areas. Whereas before Austin and TJ could feed 25 to 50 people at a time, now, thanks to corporate and community support, they can feed 800 to 2,000 people at once.

    But Austin isn't just filling bellies. He's improving the lives of those he meets. On that first trip to Firehouse Ministries, TJ and Austin talked to a man named Raymont. The respect Austin gave 41-year-old Raymont touched the man. TJ helped Raymont collect all the credentials(资格) he needed to get a driver's license. The license helped Raymont get a job. And with money in the bank, he was able to rent his own apartment. All that was made possible because a little boy took the time to care.
