Electric Shocks Can Be Fatal
Government statistics recently showed that in theUK, more than 3,000 people a year experience electric shocks in their homes. A smaller number of people are killed after they touch the power lines outside their homes. Electric shocks can cause a person's heart or breath to stop and are potentially fatal. It is essential for people to learn basic techniques to deal with such emergencies.岳云鹏个人资料及图片
What to do?
● If you are the first person to reach someone who has an electric shock, don't touch him or her!
● If the victim is still holding the appliance that gives him or her the shock (e.g. a hair dryer), unplug it or turn off the power at its source.Under no circumstances can you try to move the appliance with your hands!
● Ifyou can't turn off the power, use a piece of wood, like a broom handle or a chair, to separate the victim from the appliance or the power source. You may even be able to do this with a folded newspaper.
● The victim must remain lying down. If he or she isunconscious, the victim should be placed on his or her side. But he or she should not be moved if there is a possibility of neck or spine injuries unless it is ly necessary.
黄圣池十五的月亮原唱● It is essential to maintain the victim's body heat, so make sure you cover him or her with a blanket before you do anything else. If the victim is not breathing, apply mouth-to-mouth resuscitation (人工呼吸). Keep the victim's head low until professional help arrives.
● If the electric shock has been caused by an external power line, the dangers to the victim and to anybody providing first aid are much greater.

In May this year, as part of our 150th anniversary, we asked readers aged between18 and 25 to enter an essay competition. The task was to tell us, in no more than 1,000 words, what scientific advance they would most like to see in their lifetimes, and why it mattered to them.
The response was phenomenal: we received 661 entries. Some entrants hoped that science would make their lifetimes much longer than they can currently expect. Many looked forward to work that will end climate change. Others wanted to see advances in o
ur understanding of human history, crop growth, space exploration, and medical technologies. The ideas were inspiring.
The winner is a compelling essay by Yasmin Ali, a PhD student at the University of Nottingham, UK. Ali submitted a piece on Beethoven, her brother’s hearing loss and the science which she hoped would one day cure it. It stood out to the judges as a reminder of why many scientists do research: to make the world better tomorrow than it is today.
All essays were judged by a group of Nature editors. The top ten submissions were then ranked by three members of a separate judging group: Magdalena Skipper, editor-in-chief of Nature; Faith Osier, a researcher; and Jess Wade, a physicist. All submissions were kept anonymous throughout the process.
We also selected two runners-up(非冠军的获奖者).Physicist Robert Schittkoat Harvard University in Cambridge, Massachusetts, proposes that nuclear fusion(核聚变) could offer a solution to the climate crisis, in a piece that effortlessly mixes grand ambition with gentle humour. And chemist Matthew Zajac at the University of Chicagoin Illinois wrote a
powerful personal account of why he wants to see advances in the field of same-sex reproduction.
The results show that today’s young scientists have a wealth of ideas, talent and conviction that research can transform their world. We look forward to seeing what they do next.
4. What’s the essay competition about?
A. The scientific expectation.
B. The fantastic scientific ideas.
C. The dreams of future life.
D. The celebration of anniversary.
5. Why Yasmin Ali was chosen the winner?
