Do you want to live a happier, less stressful life? Try laughing for no reason at all. That's how thousands of people start their day at Laughter Clubs around the world - and many doctors now think that having a good laugh might be one of the best ways to stay healthy. The first Laughter Club was started in Mumbai, India, in 1995 by Dr Madan Kataria. "Young children laugh about 300 times a day. Adults laugh between 7 and 15 times a day," says Dr Kataria. "Everyone's naturally good at laughing - it's the universal language. We want people to feel happy with their lives." There are now more than 500 Laughter Clubs in India and over 1,300 worldwide. Many doctors are also interested in the effects of laughter on our health. According to a 5 - year study in the body. Laughter improves our health against illness by about 40%. So, what happens at a Laughter Club? I went along to my nearest club in South London to find out. I was quite nervous at the beginning of the class, to be honest - I wasn't interested in laughing with a group of strangers, and I was worried about looking stupid. Our laughter teacher told us to clap our hands and say "ho ho ho, ha ha ha," while looking at each other. However, our bodies can't tell the difference between fake laughter and real laughter, so they still produce the same healthy effects. Surprisingly, it works! After ten minutes everybody in the room was laughing for real - and some people just couldn't stop! At the end of the class I was surprised by how relaxed and comfortable I felt. So if you're under stress, then start laughing. You might be very pleased with the results! When did the people in the club begin to laugh for real? A) After a few minutes. B) After a few hours. C) After a few seconds. D) After a few days.

(Question)
like many other fruit,Cherries are packed with antioxidants that may help to prevent cancer and heart disease,as well as slow the aging process.Perhaps you've heare about the controversy between the FD(Food and Drug Administration)and the cherry industry and wondered what it was all about.Are cherries not as healthy to eat as you thought they were?Should you stop eating cherries?The answer is no. The controversy is over certain health claims made by the cherry industry and those who sell products made from cherries,such as pills,capsules and juice,not the health benefits of cherries themselves. While many scientific studies have demonstrated the health benefits of cherries, the FDA says that makers of products containing cherries cannot claim that their products prevent, treat or cure a specific disease such as cancer. For the general population, however, the bottom line is that there is no reason not to eat cherries. There are two types of cherry: sweet and sour . Sweet cherries are often sold fresh in grocery stores. Sour cherries are canned and used in pies, and dried to be made into fruit snacks and juice. Like most other fruit,cherries are fat-free, low in calories and high in certain minerals and vitamins. They can be eaten raw, cooked or juiced; if you want year-round cherry enjoyment, they are also easy to can and enjoy at your convience. Most scientific research has centered on the health benefits of sour cherries. Sour cherries are among the top fruit as far as antioxidant levels go. According to one study, eating 20 sour cherries a day could provide the same pain relief that aspirin does. Researchers in Texas recently discovered that sour cherries contain high levels of melatonin , something produced by the body that is thought to help slow the aging process as. well as control sleep. Cherries may lower blood sugar levels and help to significantly reduce pain due to muscle damage. What would be the best title for this passage? A) The FDA's New Rule B) The Health Benefits of Cherries C) Scientific Research on Cherries D) Different Opinions about Cherries

Ques: Everybody sleeps, but what people stay up late to catch--or wake up early in order not to miss--varies by culture. From data collected, it seems the things that cause us to lose the most sleep, on average, are sporting events, time changes, and holidays. Around the world, people changed sleep patterns thanks to the start or end of daylight savings time. Russians, for example, began to wake up about a half-hour later each day after President Vladimir Putin shifted the country permanently to "winter time"starting on October 36. Russia's other late nights and early mornings generally correspond to public holidays. On New Year's Eve, Russians have the world's latest bedtime, hitting the hay at around 3:30 am. Russians also get up an hour later on International Women's Day, the day for treating and celebrating female relatives. Similarly, Americans' late nights late mornings, and longest sleeps fall on three-day weekends. Canada got the least sleep of the year the night it beat Sweden in the Olympic hockey final. The World Cup is also chiefly responsible for sleep deprivation , The worst night for sleep in the U.K. was the night of the England-Italy match on June 15. Brits stayed up a half-hour later to watch it, and then they woke up earlier than usual the next morning thanks to summer nights, the phenomenon in which the sun barely sets in northern countries in the summertime. That was nothing, though, compared to Germans, Italians, and the French, who stayed up around an hour and a half later on various days throughout the summer to watch the Cup. It should be made clear that not everyone has a device to record their sleep patterns, in some of these nations, it's likely that only the richest people do. And people who elect to track their sleep may try to get more sleep than the average person. Even if that's the case, though, the above findings are still striking, If the most health-conscious among us have such deep swings in our shut-eye levels throughout the year, how much sleep are the rest of us losing? What do we learn about the Russians regarding sleep? A) They don't sleep much on weekends. B) They get less sleep on public holidays C) They don't fall asleep until very late. D) They sleep longer than people elsewhere.

Ques:While football fans feel strongly angry and shocked about mistakes made by referees because they cannot see clearly what has happened, a small German company is quietly pleased. For Carlos Technologies, mistakes made by referees are the kind of advertising that money cannot buy. The company has developed a tiny chip that fits inside a football and determines whether the ball has crossed the goal line, by being able to discover its exact location on the field. The world football organization, FIFA, has shown interest in the technology. It is very possible that the new technology will be used in the 2018 World Cup in Russia. "We've been testing the technology at the main soccer stadium in Nuremberg for some time and more recently in an under-17 FIFA Cup in Peru," said Gunter Rohmer, a director of the company. "The technology has performed well, and we're pretty optimistic that it will be used at the games in Russia." The chip only weighs 12 grams, and is placed in the center of the football. It sends 2,000 signals a second to a receiver network of 12 antennas ,placed around the field. The receivers then send information about the ball's location to a central computer, and because it works in real time, it can immediately tell the referee whether a goal has been scored. The chip even can tell when the ball crosses the line in mid-air. Oliver Braun, one of the inventors of the chip, says that feedback from German referees was generally positive. Germany sports-wear giant Adidas is also optimistic about using this kind of chip in other ball sports. FIFA aims to test the technology later this year at another game in Japan before deciding whether or not to introduce it in all 12 stadiums in Russia for next World Cup. Carlos Technologies is pleased because _ . A) football fans are angry with referees B) their new product can satisfy football fans C) their new product will have a good market D) they can sell a lot of football in the future
