Every day in all kinds of weather, many thousands of men and women like jogging. Why has jogging slowly for long distance become so 1? Because jogging makes the heart stronger and helps people 2 weight. It can also help them feel 3 about themselves.

    Donald Robbins is a forty-two office worker, weighing about over 150 kg. He began jogging a few years ago because he felt he was too 4. At first he could only 5 about 100 yards. Two years later, he ran in a marathon race over twenty-six miles. Many joggers, like Donald Robbins, feel that if they can succeed in jogging, they can also succeed in 6 things.

    For most people, summer holidays mean sun, sea and sand, {#blank#}1{#/blank#}. She had a holiday full of ice and snow. She and her family travelled across Greenland! Starting just above the Arctic Circle (北极圈), Sarah's family used dogsleds with kites to cross the world's biggest island.

    Sarah says {#blank#}2{#/blank#}. "There is only snow, ice, and more snow. " The family travelled 15 miles a day for 22 days, moving faster when strong winds pushed along their kites.

    Then the weather became a bit hot for the dogs to pull sleds during the day, {#blank#}3{#/blank#}. The Landrys lived in tents, ate dried food, and took baths with heated water. When they weren't travelling, they played with kites and made snowmen. Using their mobile phones, the family could send and get emails even from Greenland's ice cap! The road to the top was icy and dangerous.

    {#blank#}4{#/blank#}. "Icebergs (冰山) were so bright, just like the rising sun." said Sarah. Now she and her family have returned home, {#blank#}5{#/blank#}. Next holiday, they are going to the South Pole.

There is an English saying:" Laughter is the best medicine." Until {#blank#}1{#/blank#}, few people took the saying seriously. Now however, doctors have begun to look into laughter and the effects it has on the human body. They find that it {#blank#}2{#/blank#} people's blood pressure, the heart beating and breathing. It {#blank#}3{#/blank#} works the stomach and even the feet. So laughter exercises the body and improves people's health.

As a result of these discoveries, some doctors in the United States now hold laughter clinics; in which they help to improve their patients' condition {#blank#}4{#/blank#} encouraging them to laugh. They have found that even if their patients do not really feel like {#blank#}5{#/blank#}, making them smile is enough to produce beneficial effects similar to those caused by laughter.

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.
