Laughter Yoga (瑜伽) 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 (假装) 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.

1.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.

2. What do we know about Julie from the passage?

A. She took up Laughter Yoga 30 years ago.

B. She helped make Laughter Yoga more popular.

C. She used to suffer from serious physical problems.

D. She was the first person to practise Laughter Yoga.

There are two methods by which hydrogen (氢) can be used to power cars. The first way is to use hydrogen to drive the engine, in much the same way as many cars use gas. The second method is to use the reaction of hydrogen with oxygen in a battery, making the car a kind of electric one.

The dream of producing hydrogen in the car while driving along by electrolyzing（电解）water is a long way off, so we are still at the period of batteries and filling the tank with hydrogen gas. This is the difficulty for potential car users and producers. There are only sixteen hydrogen filling stations in Los Angeles and none in 99% of other cities worldwide.

Indeed, some of the big name automobile producers have pulled out of the race to put the first practical hydrogen car on the streets. Ford and GM have announced that they are pulling out in America and so has Renault in France.

However, the Japanese companies are pressing on. In fact, Honda introduced its first hydrogen fuel cell car in 1999. They are now producing second generation hydrogen car known as the FCX Clarity. Guess where they are available for sale? In only one city because of its filling stations.

Honda thinks that they could go into full-scale production of the FCX Clarity by 2020 if the world is prepared for them by then.

Then there are hydrogen-powered buses in several European cities including Amsterdam, Barcelona, Hamburg, London, Luxembourg and Madrid. Lotus, the makers of London taxis, have announced that they propose to manufacture hydrogen-powered taxis in time for the London Olympics.

So, the hydrogen vehicle is out there and the numbers will be growing fairly soon. The buses go back to their bus station, where an electrolyzing machine changes water into fuel for them to fill up on and the same will be the case for many of London’s taxis.

Unfortunately, getting fuel is not the only difficulty for the average motorist, a number of these vehicles cost about $300,000 each.

1.According to the text, hydrogen-powered buses ________.

2.What does the underlined word “them” in paragraph 5 refer to?

3.Where are hydrogen cars currently available for sale?

4.We can learn from the text that ________.
