Are you nervous about climbing because you think it's too dangerous?Do you feel you're not fit enough to climb?Do you know how to start climbing?

    Let's consider the idea that climbing is dangerous.Being afraid is natural,but if you use suitable ropes and other climbing equipments you will feel completely safe.Climbers are usually very careful because they know what they are doing is dangerous.Accidents may happen,but when they do,they tend to attract a lot of publicity.As a result, people think there are many more accidents than there are in reality.

    You cannot expect to start climbing straight away.Climbing is a challenge and challenges take time.It is necessary first of all that you achieve a good level of fitness.Begin as soon as you become interested in climbing—go to the gym,go swimming,take up jogging and continue to do so throughout your training period.

    Discover as much as you can about climbing.Visit the library and find books especially for beginners or buy climbing magazines and look for articles which describe your situation.Look up information on the Internet.Find out about equipment,methods and places to go.

    Next,take a course on a climbing wall.There are plenty of climbing walls all over the country which have trained and qualified people as instructors.Call your local leisure centre to find out if there is one in your area.These training sessions are a quick way to get experience and you are likely to meet other beginners.After this,you can do an outside course or join a club where you can meet climbers of all abilities and eventually join in group-climbing events.

    At first you may not understand the importance of a good training period,but after you have completed your first climb and you are standing safely at the top of a rock feeling thrilled,then you will know it was the right thing to do.

The Secret of a Long Life

    I am Peter Brown. I am a writer with an important magazine. The other day I saw a white-haired man sitting on the chair in front of his house. I could see the wrinkles (皱纹) in his face and neck, and his wrinkled hands. Articles on the secrets of living to an old age are always popular with our readers, so I decided to write a story and discover the secret of this man's long life. As I went near him, I said:

    “Sir, would it be okay if I talked with you for just a moment?”

    “Not at all. Actually, it would make me very happy. I get very bored sitting here, even for a short time. Until a little while ago, I lived a full and active life without a moment's rest.”

    “Well, they say that a lot of activities help one to live a long time.”

    “That's true, very true. I still feel very well, although my step has slowed down a little.”

    The conversation continued in that way for a while. Although I tried to be very thoughtful about getting information from older people, it seemed to me that it would now be all right to begin to ask some polite questions.

    “Would it be okay if I smoked?”

    “Not at all.”

    “I'd offer you one, but I suppose you probably don't smoke, or drink, or…”

    “You're wrong! I've always smoked a great deal. And until a little while ago, I went dancing every night. And as for alcoholic drinks ...”

    “Do you mean to say that you've done these things all your life?”

    “Of course. Why does that surprise you so much?”

    “I've always been told that doing those things is bad for the health.”

    “Nonsense!”

    “I suppose that you have another secret ... a lot of fruit... vegetables ... a lot of exercise in the fresh air…”

    “Don't be silly! I hate exercise in the fresh air, and I don't like any kind of vegetable.”

    “This is unbelievable!”

    “What do you mean, unbelievable? What are you talking about?”

    “It's just that I can't understand how you've been able to live like that and to have lasted so long. Tell me, how old are you?”

    “Me? I'm twenty-eight. Why?”

    Two summers ago I was about to turn fifty and wanted to do something I'd never done before. My daughter Bailey thought skydiving (跳伞) would be perfect for me. I can promise you that of all the things I was thinking of doing, jumping out of an airplane never came close to making the list. As I age, I seem to have developed a growing fear of heights.

    After several requests from my daughter, I finally said yes and she looked almost shocked. I told a friend what we were doing, then we set off. We had a 3-hour drive to the jump site. We drove through some beautiful countryside, but then we passed a small cemetery(墓地). Then we passed another cemetery and another one. I asked if so many people died jumping out of airplanes in this area that they needed to keep building more cemeteries to bury all the bodies!

    As we squeezed into the little plane, I tightly held the right hand of my partner Ronnie. The short ride to altitude was cruel for me. As Bailey stepped to the door, she looked back at me and said “Dad, I'm sure you can do it!” I said yes as she rolled out. I immediately looked behind me and said “RONNIE I AM NOT FEELING GOOD!” He said, “It's going to be great. Besides, it's too late now anyway”, and we jumped out.

    The next five minutes were some of the most amazing of my life. It was so beautiful and peaceful—except for the parts where I was screaming. I prayed to God for the parachute (降落伞) to open, but mostly I told Him how thankful I was for my life and being with me through good and bad.

    Sitting has been called the new smoking for its supposed Public health risks, especially for people with sitting down office jobs. Over the past 15 years or so sitting has been connected with heart disease and diabetes (糖尿病). But is sitting really that risky?

    In our latest study we examined if not only the total amount of sitting, but different types of sitting, were connected with developing type 2 diabetes. We wanted to see if there was any difference among sitting watching TV, sitting at work, or sitting at home but not watching TV.

    We studied sitting habits of 4. 811 middle-aged people, who didn't have diabetes or heart problems at the start of the study. Over the next 13 years, 402 people developed diabetes. Once we considered obesity (AE RF), Physical activity, and other things that may develop type 2 diabetes, neither total sitting time, sitting at work nor sitting at home but not watching TV were connected with developing diabetes. We found only a weak connection with the time spent sitting watching TV and an increased risk of developing diabetes.

    This is different from the results of five older TV studies that showed a stronger connection. But hardly any of the included studies mentioned obesity, a major cause of diabetes.

    For people who are physically inactive, though, the story's different. Two recent studies show the total time spent sitting a day is connected with developing diabetes, but only in people who are physically inactive or both physically inactive and obese.

    That's not the whole story. At least two things determine if sitting is a risk factor in its own right: the type and situation of sitting.

    For example, sitting down at work isn't strongly connected with long-term health risks, Perhaps that's because higher position jobs needs more sitting, and higher socioeconomic (社会经济) position is connected with a lower risk of disease. It's a different case for sitting watching TV, the type of sitting most possibly connected with long-term health risks. People who watch a lot of TV tend to (a) be of lower socioeconomic positions, unemployed, have poorer mental (精神上的) health, eat unhealthy foods and face more unhealthy food advertising.

    Like any new ninth-grader on the first day of school, Joemar Class had ninth-grader- emotion (情绪). He's not used to school in Hartford. He's used to going to school in his home town of Florida, used to seeing his friends, used to having class in Spanish.

    "Nervioso," he said in Spanish.

    We first met Joemar in mid-October in the San Juan Airport. His father, Guillermo Class, had sold his car to buy plane tickets to get his kids and fly them up from Puerto Rico. The island was almost destroyed (毁坏) by the deadly storm—Hurricane Maria.

    Now, they are settling into their new home in Hartford's South End. A week later, and, using his wife's car, Class drove 16-year-old Joemar to his first day at Bulkeley High School. After a short ride, he got out in front of his new school. Inside, he met Gretchen Levitz—the school's program director.

    "I see you have new uniform (校服)," Levitz said. "You look great. Are you ready for a good first day?"

    Then he met couple of teachers.

     "Hello," they each said in Spanish. They asked where he's from, and told him they were happy to see him. Then Levitz took him on a quick tour of the school before classes began—to her office the school store, the library, and the dining hall.

    A total of 19 languages are spoken in Bulkeley High School. "We have so many new students coming here from other countries every single day," Levitz said. "So it's not like he's the only one who has that feeling."

    "You could tell he's little worried," Guillermo said as we left." But, at the same time, he's looking forward to it."
