    Happiness is for everyone. You don't need to care about those people who have beautiful houses with large gardens and swimming pools or those who have nice cars and a lot of money and so on. Why? Because those who have big houses may often feel lonely and those who have cars may want to walk on the country roads at their free time.

When you are in trouble at school, your friends will help you; when you study hard at your lessons, your parents are always taking good care of your life and your health; when you get success, your friends will say congratulations to you; when you do something wrong, people around you will help you to correct it. And when you do something good to others, you will feel happy, too. All these are your happiness. If you notice a bit of them, you can see that happiness is always around you.
Happiness is not the same as money. It is a feeling of your heart. When you are poor, you can also say you are very happy, because you have something else that can't be bought with money. When you meet with difficulties, you can say loudly you are very happy, because you have more chances to challenge(向…挑战)yourself. So you can not always say you are poor and you have bad luck. As the saying goes, life is like a revolving(旋转)door. When it closes, it also opens. If you take every chance you get, you can be a happy and lucky person.

      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 (笑声) 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 is 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 l,300 in the world.

Many doctors are also interested in the effects (效果) of laughter on our health. According to a 5-year study at the UCLA School of Medicine in California, with laughing there is less stress 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 real laughter and unreal laughter, so they still produce the same healthy effects.

      Surprisingly, it worked! 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!

    “A cold can disappear in two days. Seventy percent of people who catch a cold feel better within a week, but it is unusual to have the common cold for as long as two weeks, ” says Gary Rogg, a medicine specialist (专家) at Montefiore Medical Center in New York.

    Why does your cold seem to be staying for longer than it should? Here are some possible reasons.

    Getting Less Sleep

    Sleep plays an important role in our system. In fact, a study proved that people who got less than seven hours of sleep per night were nearly three times more likely to catch a cold than people who slept for eight hours or more.

Low on Water

    Water plays an important part in your body. If your cold won't go away, consider drinking more water.

    Treating the Wrong Illness

    The common cold can easily be mixed with other illnesses. Often, people believe they've had a cold for a few weeks and may not realize that they aren't getting better because they've been treating the wrong illness.

Exercising Too Hard

    “People ask me all the time,' Should I exercise when I have a cold?'” Katona says. “My answer is usually yes', but do it at a lower level. If you do it at a high level, you may get even worse.”

    So, what does Katona consider to be a lower level? The answer is taking a walk, not running five miles.

    Have you ever had the flu(流感)? If you have, you know how bad it can make you feel. Most kids will get the flu sometime during their school years.

    When you have the flu, you usually get a fever(发烧) (which can be high), have a cough(咳嗽), feel very tired, and may have a sore throat(喉咙痛) as well. It can make you feel sick for a few days or for as long as a week. Sometimes, it can be hard to tell if you have the flu or a cold, but with the flu, you'll usually have a higher fever and feel much worse.

    The flu is a type of virus(病毒), which means medicine will only help the symptoms such as the cough and fever. For most kids, the flu comes and goes, but for some, it can be a serious illness. Most kids get the flu in winter because germs(细菌) spread(传播) more easily when kids are inside in settings such as classrooms.

    The best way to stop from getting the flu is to wash your hands often, keep your hands to yourself, and go to your doctor for the flu shot(注射) or mist(喷雾).

    A temporary hospital has been set up by members of the California National Guard in Indio, California, in the US.

    Feng Bangli, a resident of Wuhan, Hubei, began to have a fever at the end of January and suspected that he had been infected (感染) with the virus. He tried several times to be admitted to a hospital but failed. He eventually gave up and stayed at home, taking drugs prescribed (开药方) by doctors.

    At that time, "too many patients were waiting to see doctors at every hospital, and it was not possible for me to get a bed," said Feng. Days later, with the community staff's help, Feng tested positive for COVID-19 and was sent to a makeshift hospital (临时医院) for treatment.

    "Without such makeshift hospitals, many COVID-19 patients like me may never have found a bed," said Feng, who recovered and was discharged (获准离开) from the makeshift hospital in Wuchang district at the end of February after staying there for 12 days.

    Like Feng, more than 12,000 COVID-19 patients in Wuhan received treatment and care at 15 makeshift hospitals, which were converted (改造) from exhibition halls, sports stadiums and warehouses (仓库). These hospitals, which mainly received patients with mild symptoms (轻症), contained one in every four confirmed COVID-19 patients in the city, said Ma Xiaowei, minister of China's National Health Commission.   

    "Building makeshift hospitals was a key decision made in the critical (关键的) moment when Wuhan was facing a formidable task of epidemic (疫情) control, and it has played an indispensable (不可获缺的) role in both prevention and treatment of the disease," he said.

    Makeshift hospitals have greatly eased pressure on designated (指定的) hospitals to receive and treat patients, which made it possible to treat and isolate (隔离) all people in need, said Xu Junmei, vice-president of Wuchang makeshift hospital. "They were the life vessels (生命之舟) during the peak of the epidemic."   

    Makeshift hospitals have now been embraced (接受) in other countries. Eight makeshift hospitals are being built in Tehran, Iran, to fight against the virus. The one converted from the Iran Mall, the largest shopping mall in the country, is expected to have a total of 3,000 beds, according to People's Daily.   

    On March 29, New York converted a grassy meadow (草坪) in Central Park into a makeshift hospital, where it will provide 68 hospital beds.

    "Considering the ways we can increase hospital capacity right now is incredibly important," Dr Andrew Ibrahim, a surgeon at the University of Michigan told Architecture. "If hospitals do become overwhelmed (压垮的), and new facilities (设施) need to be built."

Masks, a simple protective tool, have been used by people for a long time. They can not only prevent epidemics(时疫), but also protect us from other harmful things, such as smog and chemicals. Let's take a look.

During the1st century, lots of people in the Roman Empire worked underground in mines ( 矿井 ). Pliny the Elder (23-79), a Roman philosopher, used animal bladders ( 膀胱) to protect miners from the dust. This was the first recorded use of protective masks.

Italian artist and inventor Leonardo da Vinci (1452-1519) advised people to wear a woven (纺织的) cloth dipped (蘸) in water over their faces to protect against harmful chemicals.

In 1848, American Lewis Hassley became the first person to patent (注册专利) a protective mask for miners. In 1897, Polish-Austrian doctor Johann Von Mikulicz Radecki designed a simple mask with one layer of gauze (纱布). This was the first use of a surgical (外科的) mask.

In 1910, the pneumonic plague ( 肺鼠疫 ) broke out in Northeast    China.

It was made of two layers of gauze. The mask was praised by experts around the world because it could be produced easily and cheaply.

Today, with several outbreaks of flu and the air pollution in recent years, masks have continued to develop. They can filter out (过滤掉) fine particulate matter ( 微粒物). China is now the world's largest mask producer, making about half of the world's masks.
