    Can you imagine astronauts' everyday life in space? {#blank#}1{#/blank#}They do the same things as us, but they do them differently.

    {#blank#}2{#/blank#} Gravity(重力) holds the food down and keeps the water in the glass. But there is almost no gravity in space, so food can float(漂浮)away, and astronauts must eat and drink carefully.

    Sleeping is very different in space. {#blank#}3{#/blank#} They tie the bag to a wall so that they won't float away, and astronauts must eat and drink carefully.

    Exercise is very important in space. On earth, your legs carry your body, but in space, astronauts float. {#blank#}4{#/blank#} This is very bad for their legs, so they must exercise for thirty minutes every day.

    After a day's work, astronauts relax. They may listen to music, read, watch films, play games, or talk to their friends and families by radio.{#blank#}5{#/blank#}

A. So they do not use their legs often.

B It's very expensive to take food into space.

C. Sometimes they just enjoy floating in the air.

D. They also need to eat, sleep, exercise and relax.

E. On earth, we put food on a plate and water in a glass.

F. Astronauts have already visited the Moon and lived on space stations.

G. Some astronauts like to float in the air, but most like to be in a sleeping bag.

    Chris is not a traditional explorer(探险者)— he usually works in an office for a large organization. Yet his job can sometimes be just as exciting and dangerous as being an explorer.

    Chris works for MSF, an organization also known as Doctors Without Borders (无国界医生). MSF sends trained doctors all over the world to help people after a war or a disaster. Chris is a doctor from France who has travelled to many places to organize programmes that help people.

At the moment, there are over 27,000 trained doctors and nurses taking part in MSF projects and tasks. The organization received the Nobel Peace Prize in 1999. All kinds of doctors can volunteer for MSF. They need to be prepared to go almost anywhere in the world and, of course, they should expect difficult conditions. Doctors with experience in tropical(热带的)diseases are especially useful because most of MSF's work is in Africa. When MSF accepts a doctor for a task, he has to go for at least six months. When doctors have completed a few tasks, they might be sent on an emergency task following a disaster, such as an earthquake.

    But why would a doctor leave a comfortable life and a good pay to join MSF? According to Chris, the experience you gain is a great help in your work. Besides, just like the explorers of the past, you need to keep an open mind and learn to get on well with the people you meet. Above all, at the end of each task, you have made a real difference to people's lives.
