Laughter Yoga   is a unique technique invented by Dr Kataria, a doctor from India, by which you can learn to "Laugh for No Reason". You don't even need a sense of humor, no funny jokes or comedy programs -- just a willingness to laugh -- and in the present climate everyone needs to laugh more. Laughter Yoga is a combination of Laughter Exercises and Yogic Breathing, so that you increase the amount of oxygen in your body while being playful, resulting in you feeling healthier, energetic and alive. This actually changes the physical conditions of your body so that you start to feel happier. Laughter Yoga is generally done in groups although it can be practiced alone. When you make eye contact with someone and you're both willing to laugh, the laughter is increased. However, we do say that you can "Fake   it, fake it till you make it" because the body doesn't know the difference between fake and true laughter; as long as you're willing to laugh you'll experience the same health benefits. Laughter Yoga started in a park in Mumbai in 1995 with just 5 participants, and now there're over 6,000 laughter clubs in 60 different countries -- showing the willingness of the world to laugh together. In the UK, Julie was one of the first people to train as a Laughter Leader with Dr Kataria in June 2002. In 2006 she was awarded Laughter Ambassador for her selfless service to promote Laughter Yoga. "Yoga has been part of my life for 30 years but 7 years ago my life changed when I discovered Laughter Yoga. I believe laughter and yoga are both good for your health," says Julie. Why do people practicing Laughter Yoga laugh a lot? A) They have a sense of humor. B) They are amused by jokes. C) They are willing to laugh. D) They can't help laughing a lot.

The Post Office in Britain is famous for getting letters and parcels to places to which they should be sent. The problem is that we the public have to observe the rules. For example, we must put a stamp on a letter. If we don't, the receiver will have to pay double. We often see the sign ALL LETTERS MUST BE CORRECTLY ADDRESSED. These days, this means having to use postcodes. If you didn't use a postcode, it's no good complaining that your letter should have arrived sooner. Parcels are a problem because they must be correctly packaged. If Aunt Sophie is going to send you a jar of your favorite jam, she will have to wrap it up well. The most important thing we have to do is to address our letters and parcels legibly  and correctly. This means clear handwriting and correct spelling. What we should do and what we actually do are often miles apart. Recently, the Post Office had to deliver a letter which showed a name followed by the word Arijaba. What is this, do you think? Arabic? Hiodustani ? Wrong both times! Say it out loud and you'll see it's just plain English. HARWICH HARBOUR! When we post parcels, we must   _  . A) address them correctly B) address them clearly C) package them correctly D) all of the above

If you haven't already, you too should switch to the latest eco-friendly, energy-efficient, energy-saving LED (Light Emitting Diode) lighting. As the world becomes more focused on green issues, everyone should do their part in practicing energy efficiency, recycling, cutting down their CO2emissions and much, much more. One of the most successful campaigns that started in Australia is the now world-famous"Earth Hour". 2.2 million of Sydney's residents turned off their lights for an hour in a mass attempt to save energy. The following year, the same idea was adopted by a whole host of different cities. This is a great example of a campaign to promote eco-friendly options and energy efficiency. But while it clearly raises awareness, it is not a long-term solution to energy saving across the developed world. A long-term solution can be found in the form of switching to LED lighting rather than the traditional halogen lights  found in a typical home. Put simply, LED lighting is the future of lighting. LED lamps use up only a fraction of the energy compared to that of regular lamps. They also produce a quality flicker-free light, and will last longer than a regular light with 50,000 hours being realistic. Not only are they longer lasting and more energy-efficient with no sacrifice in light quality, but they may quickly become a possible substitute   for regular lamps that have been previously installed by homes and businesses. An ordinary 50 watt low-voltage halogen light on for 4 hours a day would cost $ 25 per year to run. With a life span of around 3,000 hours it will typically stop working at the two-year mark. Compared with the regular one, an LED light of 50 watts operating for the same period will cost roughly $ 6 per year to run and last 50,000 hours. That means it won't have to be replaced for 24 years! It really is a _ to switch to energy-saving LED lighting. Plus, you will be doing your bit for the environment by becoming more eco-friendly. How should we save energy according to the author? A) Raise public awareness. B) Turn off the lights. C) Hold"Earth Hour". D) Use LED lights.

Intellectual property (IP) is a product of the mind that has commercial value. The concept dates back to 1623, when the first patent law to protect IP rights was passed. IP rights protect an artist from having his/her creative ideas copied by another. For example, if somebody generated an idea for a novel, that idea is protected by IP rights. If someone else wishes to represent the idea or develop it further, he/she must consult the original artists, who will normally be rewarded financially for its use. Back in the 17thcentury, IP rights were primarily carried out to protect newly developed manufacturing processes against stealing, but today intellectual property rights are also enjoyed by those who create music, art and literature. In recent years, IP rights have been the focus of a great deal of discussion because of a technology which looks set to weaken them altogether: the Internet. Many years ago, if you wanted a recoding of a song, you would have to purchase it from a music store; if a novel, from a book store. In those days, IP rights were easily protected since it was very difficult to obtain intellectual property without paying for it. However, a lot of IP, including songs, films, books and artwork, can be downloaded today free of charge using the internet. This practice has now taken the world by storm, dramatically affecting the way in which we view IP rights. According to the writer, in the beginning, IP rights were mainly of use to   _  . A) those creating music, art and literature B) novelists C) those not receiving financial reward for their work D) engineers and inventors
