Every night in Jinan University in Guangzhou, {#blank#}1{#/blank#}play diabolo (空竹) as a crowd watches in amazement.

    Chen Zhelun, 25, a Malaysian-Chinese started the diabolo club, which helps to increase the popularity of this traditional Chinese game. He is one of many students expressing their interest in the country's cultural heritage (遗产) by {#blank#}2{#/blank#}.

    The diabolo, which came from China, is popular among Chinese living in Malaysia.

    "We played diabolo from primary school onward. I thought I could find someone {#blank#}3{#/blank#}in China, but only a few students knew about it. So I started a club to develop it," says Chen.

    To Chen's surprise, the old game has interested a huge crowd—more than 1,000students have joined the club.

    "It {#blank#}4{#/blank#}and it's fun," says Chen.

    But some prefer quieter activities. Every weekend, one classroom in Shenzhen University is always crowded, but it's unusually silent. The members of Lanting Calligraphy Club are writing Chinese characters with traditional brushes.

    As head of the traditional Chinese local operas club, Kong Yanquan plans to put modern elements (元素) into traditional culture to get students to join his club.

    "I think it's everyone's duty {#blank#}5{#/blank#}China's traditional culture among young people," he says.

    Walt Disney began to make cartoon films when he was a young man. But he didn't have much money then. One day a mouse ran near his desk while he was working in his small office.

    "Would you like to be my pet?" Disney decided to make a cartoon about it.

    "I am making a cartoon about a mouse named Mortimer," he told his wife.

    "Mortimer Mouse? I think Mickey Mouse would be a better name," she said.

    "You are right," Disney agreed and made many Mickey Mouse cartoons.

    People all over the world saw Mickey and loved it. Mickey Mouse made Disney famous. Then came Donald Duck, and Goofy Dog and others. Disney began to make long cartoons. Then he made cartoon films for television.

    In 1955, Disney opened a wonderful amusement park in California. Real boats, castles, trains, mountains, rivers, all are in one beautiful park. Millions of people came to Disneyland.

    He died in 1966, but the world will not forget him. Mickey Mouse and all his cartoons will help us to remember him.

Astronauts would face dangers both getting to and surviving (生存) on Mars. Let's learn about surviving a trip to Mars.

What would it take to keep people safe and healthy on a trip to Mars? Scientists are already working on it, though the trip may be many years later.

Over the last 60 years, many spaceships have flown by orbited（沿轨道运行）and even landed on the Red Planet. However, machines cannot replace humans. That's why the United States, China and other countries want to send people to Mars. But surviving on this trip would not be easy.

A trip to Mars would be the farthest journey in human(人类) history. Mars is about 225 million kilometers away, so it would take astronauts at least 180 days to reach there. However, it only takes a few days to get to the Moon.

Space travel is dangerous. For one thing, staying in space for long periods makes the human body weak. Also, it puts pressure behind the eyes and causes eye problems. But gravity(重力) machines could help.

Then there's space radiation(辐射) to worry about. It is bad for astronauts when they have long journeys. Scientists are working out the issue. They have found that taking certain vitamins can help.

Astronauts will have to pack light to lift off from the earth. But they won't be able to get the things they need easily. Astronauts on the space station practice for this by growing lettuce and other food in space. Engineers are developing 3D printing techniques（技术）which can allow future Mars astronauts to build what they want.

As the weather gets warmer，there are few things that are better to do than travel．But traveling might not be that fun for everyone，especially for those who have motion sickness（晕动症）．

Motion sickness is also called travel sickness．It is a common experience for many people．Depending on how you travel，it can be called carsickness or seasickness．People with motion sickness feel very uncomfortable while they are in motion．They feel sick and dizzy，like the room around them won't stop spinning．

It is generally believed that motion sickness happens when your senses become confused （困惑的）with each other，Scientific American reported．

We use different parts of our body to sense movement．Our eyes tell us if we are moving．The inner ears （内耳） contain a special liquid that helps us sense our direction and balance．Our muscles react to movement．

When you move around，these body parts work well together．But when you are in a car or an airplane，they get confused．Your inner ear signals that you're moving．This mismatch gives us motion sickness．

But some people are less sensitive to motion sickness．This may be because they have certain genes （基因） that prevent mismatching senses，Bethann Hromatka，told the Atlantic．

Although there are many ways to deal with motion sickness，scientists believe that the key is to simply try to adapt to it．For example，some astronauts do special exercises that give them mild motion sickness．After a week or two，the astronauts become used to it and don't feel uncomfortable anymore，a NASA flight doctor，told the BBC．
