Imagine you are going to a space camp and Captain Brown has been invited to give a talk. Discuss the questions you would like to ask him and then make a list.
A: Hey, guys. We’re going to met a real astronaut. Isn’t it exciting
B: Yeah. I can’t wait to see Captain Brown! I’m really curious about his life in space. I have plenty of questions to ask him.
Step 2 Practise one by one

Discussion
The advantages and disadvantages of space exploration
Human beings have worked with the space for decades. From the observation of stars in the sky of ancient people to the first satellite launched into space. From the first spaceship flying into the far space to the first people landed onto the moon . Human beings have done so much with the space .
Why, you may wonder, should we did this What advantages did we take of space exploring
For example, It is because space exploring that I can listen a radio sitting in my room, I can watch TV at home to get information effectively .I can use a computer in my home to learn things easily without even using a wire, because I'm using a wireless network card .And we have learnt more about the space ,we may find some other energy or resources of the out space .All these are the benefits.
But there are also risks.
First, the space may be polluted by human beings ,for we have sent so many satellites into the space in the course of exploring.
Then, there may be another horrific truth that we may be found by aliens because of the satellites sent to the far space .This is undoubtedly a disaster for us , human beings .
As far as human concerns, we have to endeavor to develop technology to improve our life quality and to protect ourselves from disasters in the future. So although there are risks, we have to go ahead, we have to explore the space.
太空探索的利与弊
人类已经在太空工作了几十年。从古人对天上星星的观察到第一颗发射到太空的卫星。从第一艘飞向遥远太空的宇宙飞船到第一批登上月球的人类。人类已经为太空做了很多。
你可能会问，我们为什么要这么做 我们进行太空探索有什么好处
例如,这是因为空间探索,我可以听收音机坐在我的房间,我可以在家看电视获取信息有效,我可以用电脑在家里学习东西很容易甚至没有使用一根电线,因为我用的是无线网卡,我们学到了更多的空间,我们可能会发现一些其他的能源或资源空间。所有这些都是好处。
但也存在风险。
首先，太空可能会被人类污染，因为我们在探索的过程中已经向太空发射了太多的卫星。
然后，可能还有另一个可怕的事实，我们可能会被外星人发现，因为卫星发送到遥远的太空，这无疑是一个灾难，我们人类。
就人类而言，我们必须努力开发技术来提高我们的生活质量，并在未来保护我们自己免受灾难。所以尽管有风险，我们必须前进，我们必须探索太空。
Living in Space
Being an astronaut is fun, but life in space can be difficult. Here are some everyday things that are different in space.
Sleeping
Astronauts wear pajamas and brush their teeth, but they don’t sleep in beds. In space you float around because there is no gravity. Astronauts go into a small cupboard and then get into a sleeping bag. They look like big sausages! Then they tie the bag to the wall and close the door.
Step 5 Learn the life in space
Cooking
How do you make a hot meal with no kitchen If the food is in a bag, like spaghetti or soup, astronauts put it in a machine and press a button. This puts hot water into the bag. If the food is in a box, like fish or vegetables, astronauts heat it in a small oven. Some foods are dry or fresh, like fruit and bread. Astronauts don’t need to cook them.
Eating
On Earth we use knives, forks, spoons, and chopsticks. Astronauts use these as well, but they also use scissors and straws. They need scissors to cut open food bags and straws to drink – you can’t use a cup in space because the drink will float around the spaceship!
There aren’t any tables, either. Astronauts tie a tray to their legs. This tray holds all the food.
Doing Exercise
Astronauts do exercise for two hours every day. They run on a treadmill and use a special machine to exercise their arms. They have to tie their feet to the machines so they don’t float away!
Washing
When astronauts want a shower, they go into a big tube and close the top. They use a pipe to spray water on themselves and then a vacuum cleaner to dry. When they brush their teeth, they drink the water and eat the toothpaste. Yuck!
Did you know
Astronauts can’t wash clothes in space. There isn’t enough water.
太空生活
宇航员的工作是有趣的，但又是艰巨的。以下是他们在太空的日常。
睡觉
宇航员也是穿着睡衣刷好牙齿再睡觉的，但是他们不是睡在床上。由于失重，他们会在太空中漂浮，所以他们要进入一个小柜子里然后钻进睡袋里睡觉。
做饭
没有厨房怎么做顿热饭？像意面，汤这种袋装食物，宇航员会把它放入机器中按下按钮，机器里的热水就会加热食物。如果是盒装食物，比如蔬菜，宇航员会把它们放入小烤箱中加热。一些像水果或面包这类的食物，宇航员就不需要加热了。
进食
在地球上，我们用刀叉、勺子和筷子是吃饭。宇航员也是这样，同时他们也用剪刀和吸管。剪刀剪开食品包装袋，吸管用来喝水。因为失重，他们无法再太空中用杯子喝水！
他们也无法用桌子，所以通常把食物托盘系在他们的腿上，食物都放在托盘上。
做运动
宇航员每天要做两小时的运动，他们在跑步机上跑步，用特殊的机器来锻炼手臂。当然，他们需要把腿系在机器上以防自己飘起来！
洗澡
宇航员在一个大的管子里洗澡，顶部是封起来的。他们用管道来冲洗，用真空吸尘器来吹干。刷牙时，他们要喝了刷牙水，吃了牙膏。额……
你知道吗？
宇航员在太空中是不洗衣服的，因为没有足够的水。
People argue whether space exploration is worth or not.
There are some benefits: First, for farmers; second, promote technology and last, find another planets for living.
