Government statistics recently showed that in the UK, more than 3,000 people a year experience electric shocks in their home. A smaller number of people are killed after contact with power lines outside the home. Electric shocks can cause a person's heart or breathing to stop, can also cause burns and are potentially fatal. It is essential for people to learn basic first aid techniques to deal with such emergencies. What to do? If you are the first person to reach someone who has had an electric shock, don't touch them! If they are still holding the appliance that has given them shock (e.g. a hair dryer), unplug it or turn off the power at its source. _ If you 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 they are unconscious, victims should be placed on their side. But they should not be moved if there is a possibility of neck or spine injuries unless it is absolutely necessary. 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 . 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. What kind of passage is it? A) An advertisement. B) A horror story. C) A news report. D) First aid emergency advice.

A young girl decided to study judo despite the fact that she had lost her left arm in a car accident. The girl began lessons with an old Japanese judo instructor. The girl was doing well. So she couldn't understand why, after three months of training, the instructor had taught her only one move. "Instructor," the girl finally said, "Shouldn't I be learning more moves?" "This is the only move you know, but this is the only move you'll ever need to know," the instructor replied. Not quite understanding, but believing in her teacher, the girl kept training. Several months later, the instructor took the girl to her first tournament . Surprising herself, the girl easily won her first two matches. The third match proved to be more difficult, but after some time, her opponent became impatient. The girl used her one move to win the match. Still amazed by her success, the girl was now in the finals. This time, her opponent was bigger, stronger and more experienced. For a while, the girl appeared to be overmatched. Concerned that the girl might get hurt, the referee called a time-out . She was about to stop the match when the instructor intervened . "No," the instructor insisted, "Let her continue." Soon after the match restarted, her opponent made an important mistake: she dropped her guard. Instantly, the girl used her move to defeat her opponent. The girl had won the match and the tournament. She was the champion. On the way home, the girl and her teacher reviewed every move in each match. Then the girl asked what was really on her mind. "Instructor, how did I win the tournament with only one move?" "You won for two reasons," the teacher answered. "First, you've almost mastered one of the most difficult throws in all of judo. Second, the only known defense for that move is for your opponent to grab your left arm." What can we learn from the passage? A) Sometimes our biggest weakness may become our biggest strength B) We need to spare no effort to do everything well C) Always follow our teacher's instructions and we will succeed D) If we are not afraid of our opponent, we will finally achieve our goal.

Q: It's illegal for the police to attach a GPS unit to your car without your permission, as the U.S. Supreme Court settled in 2012.But if the police are in hot pursuit of a bank robber or other escaping criminals that threaten public safety, a GPS tracker is acceptable. But exactly how can the police GPS track a car that is moving fast? The answer to that question comes from StarChase,a new police technology being used by a small but growing number of law enforcement agencies.It allows the police to fire 4.5-inch glue-covered GPS bullet-like projectiles from an air gun fixed in their police cars.If the GPS tracker makes contact with the escaping robber's car, it'll stick no matter how fast the vehicle is going.That way, the police will have a constant read on the car's location and heading.Aside from simply apprehending criminals,it's believed this new technology could help save lives.If the police successfully fire a GPS unit at a speeding criminal,they can pull back from a high-risk chase.Chases can be incredibly dangerous to all involved,including innocent bystanders and other drivers.Once the GPS bullet connects,there's no need for the chase any longer. Now,predictably,a GPS-loaded gun isn't cheap. Police departments need to pay about $5.000 per vehicle for the technology,and individual GPS bullets cost as much as $250 each.That may sound expensive,but remember:The alternative is often thousands of dollars in property damage,and great human cost in injury and lost life.According to Star Chase,their GPS bullet system has an apprehension rate of 80%without any report of inury or property damage.If you'd like to learn more about the StarChase system,Popular Mechanics has just published a good article about it.There's also plenty more information available at the company's website. When the GPS bullet sticks to the escaping robber's car,the police can _ A) know the car's condition B) ensure the robber's safety C) play a fair game with the robber D) know the car's position and direction

Q: Scientists explain why people often blame others when things don't work out. Researchers say that when it comes to fixing blame, we can't always trust our own judgment .When things go wrong and we're to blame, we 're supposed to feel guilty. Right? Not necessarily. It turns out that when we do something that causes a negative result, we actually feel less responsible for our actions. But we see the entire situation differently if things turn out well. The "blame game" is nothing new. Behavior experts have long known that people push responsibility to others, or to outside factors, when things don't work out. But the new research shows that this reaction is more than about wanting to escape blame. We actually don't believe that what happened is our fault. To learn more about the "blame game", researchers conducted a study. They asked 34 people to press keys that produced three different noises. The noises were positive (amusement, laughter), negative (fear, upset, or anger), or neutral . The volunteers were asked to try to judge the time that it took between when they pushed the button and when they heard the sounds. Volunteers felt there was longer time between their actions and the negative sounds than that between their actions and the positive ones. In their minds, the negative results were separate from their actions. Therefore, they were able to feel less responsible for them. The findings suggest that perhaps more of us need to realize that unpleasant or negative situations may actually be our fault - even if we don't see it that way. And taking more responsibility for our actions could lead to better relationships with others. This passage is likely to be selected from a book of A) medicine B) science C) entertainment D) health
