In the past decade the popularity of rock climbing has greatly increased, and so has the number of injuries. It has been estimated that rock climbing is now enjoyed by more than 9 million people in the US each year. Study findings revealed a 65% increase in the number of patients that were treated in US emergency departments for rock climbing-related injuries between 1991 and 2012.
The study, published in the online issue of the American Journal of Preventive Medicine, found that about 40,000 patients were treated in US emergency departments for rock climbing-related injuries between 1991 and 2012. The most common types of rock climbing –related injuries were fractures(骨折) and sprains （扭伤）。The ankle was the most common body part to be injured (40%). Climbers in the study ranged in age from 2 to 74, with an average age of 26. The study also found that women took up a quarter of the injuries.
Falls were the primary reason for injury with over three-quarters of the injuries occurring as the result of a fall. The severity of fall-related injuries had a lot to do with the height of the fall. Patients who were injured after falling from a height over 20 feet were 10 times more likely to be treated than patients who were injured falling from 20 feet or lower.
“We found that the climbers who fell from heights higher than 20 feet took up 70 percent of the patients treated for a rock climbing-related injury,” explained the study author Lara McKenzie, PhD, director at the Center for Injury Research and Policy at Nationwide Hospital. “This trend, combined with the fact that rock climbers have a higher hospitalization rate than other sports and recreational injuries, demonstrates the need to increase injury prevention efforts for climbers.”

A growing number of American homes are keeping African pygmy hedgehogs(刺猬) as pets. Hers are some questions and answers about the small animals whose backs and sides are covered with about 6,000 quills. Their quills are short, but hard and sharp.
Where do they come from?
The breed is a hybrid (杂种) of the four-toed hedgehog or African white-bellied hedgehog and the Algerian hedgehog. Its natural habitat is central, eastern and southern Africa. It now breaks the law to bring them into the United States.
An adult African pygmy hedgehog is 6 to 11 inches long and weighs 1 to 2 pounds. A relaxed one is generally oval (椭圆的) , with a very short tail and short limbs that keep the body close to the ground . When threatened or frightened, it rolls into a ball and forces its quills out in all directions. Female hedgehogs are a bit larger than the male ones. The face and the underside are covered with soft and white fur.
What do they eat?
In the wild, the hedgehog feeds mainly on insects. It also eats earthworms, snails and slugs, as well as small snakes and frogs. Pet owners feed cat food to hedgehogs that are kept at home by them.
How many babies can a mother hedgehog give birth to one time?

I was born into a family of five children. As the youngest child, I didn’t have many new clothes. Though my parents worked very hard, we could hardly make ends meet. The only time we would receive new clothes was at Christmas.
The family across the street lived a much better life. They just had two daughters and they were often seen wearing new dresses. The younger girl named Anna was of my age. One afternoon, she walked on the street wearing a beautiful white dress. She looked like an angel in that dress. I, together with many little girls, followed her. We just couldn’t keep our eyes off her dress. We all wished we would have such a dress one day!
That day, after coming back, I told my mom that I wanted a dress like that. My mom frowned(皱眉) she thought such a beautiful dress like that must cost an arm and a leg, but my mom kept that in mind. She worked five days a week at that time, but when Christmas was getting close, she worked even on every Saturday.
However, several days before Christmas, I changed my mind. It was Anna’s birthday that day and I was invited to her home with some other girls. After that party, I asked if I could try on her white dress. “Of course,” she said, “and you can take it if you like it.” I couldn’t believe my ears. How could she give such a beautiful dress to someone else? After trying it on, I knew why.
The dress looked beautiful, but it was uncomfortable to wear. As a matter of fact, my back was quite itchy(痒的) after I put it on. From that day on, I stopped admiring what others had. They may not be as good aswe think.
