On the day the tornado hit, there was no indication that severe weather was on its way—the sky was blue and the sun bad been out. The first alert my husband,Jimmy,67,and I,65,got came around 9 p.m., from some scrolling text on the TV Jimmy was watching. He ran upstairs to find me in our third-floor bedroom, and we changed the channel from the presidential primary debate I had been watching to our local Pensacola, Florida, station.

    No sooner had we found coverage of the tornado than it was on top of us. It was the loudest thing I have ever heard. The bones of the house shook, and the power went out. The wind began to roar through the house, most likely through blown-out windows and the door to our garage. We had three flights of steps to navigate to get to the relative safety of the first floor, because the cupboard down there is underneath a brick staircase.

    I didn't know how or if we would make it down the steps. It felt as if there were no floor underneath me as the wind lifted me off my feet. I tried to move forward, but this intense pressure held me in place.

    As we reached the last flight of steps, our front door blew out. Pieces of glass that looked like crushed ice flew everywhere. Suddenly, a three-foot-long tree branch crashed into the door frame. It flew over our heads, missing us by inches. Had we been one step up, it would have hit us.

    By the time I reached the cupboard, the tornado had been over us for about a minute. Jimmy pushed me down to the cupboard floor, but he couldn't get inside himself because of the wind. I held Jimmy's arm and tried to bring Jimmy with it. My knees were full of glass, but at that moment, I felt no pain. If I had let go, Jimmy would have flown right out the back of the house and into the bay.

    All of a sudden, Jimmy lifted off his feet like people in tornadoes do in the movies. I thought he was gone. And then everything stopped. He landed on his feet. In those first quiet moments, I couldn't believe it was over, Jimmy said he'd go outside to check. "No,"I said. "Don't leave me. Don't leave me."

    Our neighbor says the storm lasted four minutes. In that time, four of the twelve town houses in our unit were completely destroyed. Of the houses left standing, ours suffered the most damage. Amazingly, none of us were severely injured.

    China is the biggest market in the world, and many countries such as Germany, the USA, the UK and Russia do a lot of business in China. Let's have a look at some important tips to help you be successful when dealing with these nationalities.

    First, you must be punctual (准时的) with Germans. Even 5 minutes late makes a bad impression. Being punctual is also very important in the USA. In the UK, it's important to be punctual for business meetings, but nobody expects you to be on time for a social event. Half past seven really means a quarter to eight, or even eight o'clock! With Russians, you should always be on time, though it is not unusual for them to be one or even two hours late!

    It is best to dress formally and wear dark colours when you meet people from all the four countries. In Russia, designer clothes are very common. Don't be surpri if you go to an office in the UK on a Friday and find everyone wearing jeans. Many companies have “dress down Friday”, when people wear casual (随便的) clothes.

    In Germany, first names are only used by family members and close friends, so be prepared to use titles and last names. In the USA you will usually be invited to use first names almost immediately. The British are quite informal and using first names in business is more and more common, especially among younger people. In Russia, however, nobody uses first names, so use titles and last names.

    In conversation, the British and the Americans value humour, and both like to talk about sport. The weather is also a good topic of conversation with the British and the Americans, but avoid talking about politics. In Russia, say positive（肯定的） things about their country, but avoid making complaints. The Germans, however, prefer to get straight down to business!

    So, use these tips, and you will be on your way to a successful international business career!

    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(基因) 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.

    Many teenagers feel that the most important people in their lives are their friends. They believe that their family members don't know them as well as their friends do. In large families, it is quite often for brothers and sisters to fight with each other and then they can only go to their friends for some ideas.

    It is very important for teenagers to have one good friend or a group of friends. Even when they are not with their friends, they usually spend a lot of time talking among themselves on the phone. This communication is very important in children's growing up, because friends can discuss something. These things are difficult to tell their family members.

    However, parents often try to choose their children's friends for them. Some parents may even stop their children from meeting their good friends. Have you ever thought of the following questions?

    Who chooses your friends?

    Do you choose your friends or your friends choose you?

    Have you got a good friend your parents don't like?

    Your answers are welcome.

    Are you looking for some new and exciting places to take your kids to? Try some of these places.

    Visit art museums. They offer a variety of activities to excite your kids' interest. Many offer workshops for making hand-made pieces, traveling exhibits, book signings(签名) by children's favorite writers, and even musical performances and other arts.

    Head to a natural history museum. This is where kids can discover the past from dinosaur(恐龙) models to rock collections and pictures of stars in the sky. Also, ask what kind of workshops and educational programs are prepared for kids and any special events that are coming up.

    Go to a Youtheater. Look for one in your area offering plays for child and family visitors. Pre-show play shops are conducted by area artists and educators where kids can discover the secret about performing arts. Puppet(木偶) making and stage make-up are just a couple of the special offerings you might find.

    Try hands-on science. Visit one of the many hands-on science museums around the country. These science play-lands are great fun for kids and grown-ups alike. They'll keep your child mentally and physically active the whole day through while pushing buttons, experimenting, and building. When everyone is tired, enjoy a fun family science show, commonly found in these museums.
