Yellowstone Weather

    Yellowstone National Park is at high altitude. Most of the park is above 7,500 feet (2,275 meters).

    Yellowstone's weather is unpredictable. In summer, it may be warm and sunny with temperatures in the high 70s. At night in any given month, the temperature may drop close to freezing. So it is best to come prepared for cold evenings and mornings, especially if you are camping or hiking. When you leave your campsite, please leave it prepared for possible thundershowers and wind.

    A sunny warm day may become fiercely stormy with wind, rain, sleet and sometimes snow. Without enough clothing, and easy day hike or boat trip can turn into a battle for survival.

    July is a month of fun-filled activities for kids and teens as long as you know where to find them. When you want some fun activities for July, consider these ideas happening in this month.

    Eighty-five-year old Chinese pharmacologist(药理学家) Tu Youyou became China's first winner of the Nobel Prize in Physiology or Medicine when it was announced that she was one of three scientists awarded the 2015 Nobel Prize in Physiology or Medicine for their work in developing effective drugs against parastic diseases.

    Tu was honored for developing artemisin（青蒿素）,a drug for malaria that has saved millions of lives across the globe,especially in the developing world,the Nobel Assembly at karolinska Institue disclosed on its website on Monday.Tu,a Chinese trained pharmacologist and a researcher at the China Academy of Chinese Medical Sciences in Beijing, went to Stockholm, Sweden in December to receive her award, according to Cao Hongxin, the science and technology department head of the State Administration of Traditional Chinese Medicine.

    "She was calm and said she has received lots of congratulatory calls." Cao told China Daily on Monday after he telephoned Tu to congratulate her. "It's an overdue（迟来的）honor for Tu and the world's recognition of traditional Chinese medicine," he said.

    "Tu's breakthrough in winning the Nobel Prize in a natural science is the pride of the whole nation and the whole Chinese scientific community," said Zhou Dejin, spokesman of the Chinese Academy of Science, China's national research body that consists of more than one hundred research insistutes, universities and research branches,

    "The achievement of discovering artemisinin was made in the 1970s, but it only received international recognition in later years, which suggests that we might have more achievements that have reached the Nobel Prize level but have not been recognized." Zhou said.

    Employers and managers must never ignore the need for an office or industrial first aid kit. The federal government says that every workplace should be equipped with first aid kits and that employees should be taught first aid.

    Good preparation can prevent unnecessary injury, lose of productivity(生产效率), or even law suits when a workplace emergency occurs.

    An employer must first provide the proper number of first aid kits for his workers. Many kits are available for sale online by industrial first aid kit suppliers. Kits designed for ten workers cost about $15 and kits designed for fifty workers cost about $80. There are kits also available for a small office，a vehicle，or work sites. Kits should be stored in a portable(轻便的), durable, watertight container. Fix the kit to the wall so that it is easily seen and reached in an emergency. Include a list of kit's contents to ensure it is always fully stocked.

    Show each worker where the kit is located and what tools it contains. Educate each worker about possible injuries and which ones will require immediate medical attention from professionals.

    The American Red Cross sells industrial first aid kits that meet the United States' Occupational Safety and Health Administration's requirements. Several types of kits are available. The Personal Protection Kit contains gloves, gowns, and masks to protect workers from dangers like blood and bodily fluids. It costs about $15. The American Red Cross also sells industrial first aid kits for 25 or 50 workers that are both very cheap.

    Craft (手工艺）is becoming a heritage industry — but a record of disappearing skills might just come in handy in the future.

    Mr. Lobb (of John Lobb the bootmaker) mentioned that custom clothing and shoe-making were once the norm for everyone. How come，then，today a pair of normal Lobbs would set you back over £2,000? The price has obviously gone up because of lack of competition and higher wages，but would custom clothing once again be affordable to all if the demand was there? Do we just wave goodbye to these skills，or should we fight to maintain them?

    The disposable (一次性的）culture we “enjoy” today has existed in our life for almost two generations now. We like our products to be made by either a robot or invisible，cheap hands so that we can accumulate them cheaply and frequently. The concept of “craft” is something that's now largely considered to be strange，and seems to be limited to museums and dusty, independent shops. Hobby crafts such as knitting do undergo revivals (复兴)from time to time，but I think that's because they are seen as short-lived fashionable leisure pursuits rather than a craft worthy of revivals on a commercially feasible (可行的)scale.

To drive a revival in any of these crafts, you would probably need to apply the same marketing techniques that are used to sell any other items today. The consumer must believe that they just have to have it. If they don't have it now, it will either go up in price or go out of fashion — both reasons enough in themselves for a shopper to act.

    But does it finally matter if these skills will no longer serve any practicable use in the decades to come? I don't know the answer to that，but I have long thought it would be a good idea if we “banked” these skills somehow，just as we are not attempting to do with seeds. You just never know whether we'll need them in the future. Maybe it's time to establish a worldwide network of volunteers to record，through the written words and videos，as many of these dying skills as possible. Actually, a rough look on YouTube fills me with hope that an army of willing volunteers is probably out there already and just needs someone or something to gather them together.

    If you analyze people's actions, you will come to the conclusion that they all seek happiness. Every act is in fact a search for it, even if on the surface it doesn't look so. Happiness is always the main target.

    Going to the movies, eating in a restaurant and going to a party are all motivated by the desire to be happy. Who does not dream of a vacation in some fascinating locations, a new car, a new house, or the ideal match? All people daydream, and some even try to make their dream a reality. And why is that? In order to be happy!

    Many people endanger themselves by climbing steep mountains, entering unexplored caves, or diving into the deep of the ocean in order to enjoy the few moments of happiness. A thief may steal because he loves the thrill of danger, or because he desires to have quick money to spend. He is actually looking for happiness, though in a perverted way.

    Of course not all actions end in happiness. The motive is happiness, but the results do not always bring the desire. According to some spiritual traditions, we are spiritual beings in physical bodies. The spiritual part is always happy. Rather, it is happiness itself. But the physical body covers this happiness essence(本质). There is a constant desire to find out this happiness. This is the reason why happiness is constantly sought.

    However, there is no need to search for happiness or to create it, or to have all kinds of outer experiences and actions in order to feel it. On the contrary, everything has to be dropped in order to experience it. Every technique, which helps to relax the mind and calm the rush of thoughts will lead to happiness.
