Tourism probably started in Roman times. Rich Romans visited friends and family who were working in another part of the Roman empire. But when the empire broke down, this kind of tourism stopped.

    In the early 17th century, the idea of the “Grand Tour” was born. Rich young English people sailed across the English Channel（英吉利海峡）. They visited the most beautiful and important European cities of the time, including Paris in France, and Rome and Venice（威尼斯）in Italy. Their tours lasted for two to four years, and the tourists stayed a few weeks or months in each city. The “Grand Tour” was an important part of young people's education—but only for the rich.

    In the 18th century, tourism began to change. For example, people in the UK started to visit some towns, such as Bath to “take the waters”. They believed that the water there was good for their health. So large and expensive hotels were built in these towns.

    In the 19th century, travel became much more popular and faster. When the first railways were built in the 1820s, it was easier for people to travel between towns, so they started to go for holidays by the sea. And some started to have holidays in the countryside as cities became larger, noisier and dirtier.

    Traveling by sea also became faster and safer when the first steamships were built. People began to travel more to far-away countries.

    The 20th century saw cars become more and more popular among ordinary people. Planes were made larger, so ticket prices dropped and more people used them.

    Thus tourism grew. In 1949, Russian journalist Vladimir Raitz started a company called Horizon Holidays. The company organizes everything—plane tickets, hotel rooms, even food—and tourists pay for it all before they leave home. The package tour and modern tourist industry was born.

    The first travel agency in China was set up as early as 1949. But tourism did not take off until 1978. In 2002, the industry was worth 500 billion Yuan and became an important part of China's social development.

    There are a number of reasons that can be given as to why children should be taught swimming at a young age. If your child knows the basic swimming skills, you can be at peace when your child is near the water. If you are in the process of teaching your child how to swim, then here are some points that you should keep in mind.

    Help your child pick a bathing suit. If you child wants to wear bathing suit and get wet then it is certain that your child will be able to handle the water.

    If the pool has steps, then it is great. Start from these to help your child gain some confidence. You should make sure that there is one place in the pool where your child can be left safely.

    The best way to teach your children to swim is to make them join swimming classes. In this way, you will be at peace because there is a professional trainer around your children who can teach them all the tricks of swimming. You can join in the parent-child lessons to make your child feel comfortable. If your child is a bit older, then get permission and sit by the pool to watch him/her learn. When you get your child admitted to swimming classes, make sure that the lessons go according to the swimming goals that you have set for your child.

    Swimming is a fun activity and you can make it easy for your children to understand and coordinate(协调)the movements of their arms and legs will take some time. But, with regular practice and training this can be overcome. So, start with the basics and be around your children when they are learning how to swim. Once they know how to swim, then you can be at peace when they play around the water.

    A hospital has been forced to ban Pokemon Go players from the site after a monster hub(妖怪枢纽站) was found in the A&E department. Royal Stoke University Hospital discovered that its casualty unit(急诊室) is on the same spot as a Pokemon Go 'gym' ­­ where players can train their newly caught Nintendo creatures.

    The University Hospitals of North Midlands Trust agreed last week that patients can play Pokemon Go on wards because walking around is healthy. But the Trust has been forced to post a warning on its website about public access to A&E. It said if Pokemon Go becomes a major annoyance it would ask Nintendo­­ which decides on the locations of the virtual gyms according to GPS­­to have it removed from the premises(道馆).

    Kevin Parker, associate chief nurse, said, "Members of the public who do not need to be at Royal Stoke should not attempt to enter A&E or any other part of the hospital building to play the game. The A&E department is incredibly busy this summer. We want the public to understand that anybody who visits the hospital solely to play the game will provide an unwanted distraction to the important work of the hospital. I'm also aware of various reports in the media of unsafe areas that the game has been played in."

    "Royal Stoke University Hospital is a safe area where gamers can enjoy Pokemon Go." Michelle Harris, the Trust's manager, said the game could still be played by those already in hospital. "We recognize that the Pokemon Go game encourages walking and exercise, which is something that the Trust is equally keen to promote," she said.

    There are a number of "walking routes" established throughout the Trust that can be used to combine walking and playing the game. "Walking just 30 minutes, five times a week, can help reduce the risk of preventable illnesses such as obesity, diabetes, and heart disease."

    There have been several warnings about the game since its UK release. Last week a group of teenagers in Wiltshire were left stranded almost 100ft underground after they got carried away searching for Pokemon Go characters. The four boys, aged 16 and 17, ended up getting lost and had to wait to get a phone signal before they could call for help. Eventually, they contacted Dorset and Wiltshire Fire and Rescue team, who took them to safety. Damien Bence, of the fire and rescue team, said: "Pokemon Go is obviously leading people into dangerous situations."

    When I was small and my grandmother died, I couldn't understand why I had no tears. But that night when my dad tried to cheer me up, my laugh turned into crying.

    So it came as no surprise to learn that researchers believe crying and laughing come from the same part of the brain. Just as laughing has many health advantages, scientists are discovering that so, too, does crying.

    Whatever it takes for us to reduce pressure is important to our emotional health, and crying seems to work well. One study found that 85 percent of women and 73 percent of men report feeling better after crying.

    Besides, tears attract help from other people. Researchers agree that when we cry, people around us become kinder and friendlier and they are more ready to provide support and comfort. Tears also enable us to understand our emotions better; sometimes we don't even know we're very sad until we cry. We learn about our emotions through crying, and then we can deal with them.

    Just as crying can be healthy, not crying - holding back tears of anger, pain or suffering - can be bad for physical health, Studies have shown that too much control of emotions can lead to high blood pressure, heart problems and some other illnesses. If you have a health problem, doctors will certainly not ask you to cry. But when you feel like crying, don't fight it. It's a natural –and healthy-emotional response.
