2 . What is it like to travel in space? People aboard the Aurora Station（曙光女神空间站）, the world's first luxury（豪华的）space hotel, can tell you in the future. The hotel plans to welcome its first guests in 2022, CNN reported.
US company Orion Span built the hotel. It will fly 320 kilometers above Earth. It can hold six people at a time. Two of them will be workers. They may be former NASA astronauts.
Each trip aboard the station will last for 12 days. Guests there will be able to do many interesting things. For example, they will see 16 sunrises each day. They can fly and move around in zero gravity（重力）. They can also grow food in space. Later, they can bring the food back to Earth as a souvenir（纪念品）. These are the same things that astronauts usually do.
Guests can also share what they see and hear with others on Earth. They can have a video chat using a high-speed internet connection.
But the trip will be expensive. Each guest will have to pay at least $ 9.5 million（about 60 million yuan）.

3 . Have you ever dreamed of traveling in space? To travel in space, we first have to work out where our food will come from.
Today's space travellers don't go to the Moon or Mars. They go to the International Space Station（ISS）. There, the spacemen live for weeks to months.
If you visited the ISS years ago, nearly every kind of food you ate would have come from the Earth.
In 2014, scientists sent the ISS a space garden with some vegetable seeds（种子）. With water and some light, the vegetables in the garden grew. Those were the first foods being grown on the ISS. But the spacemen couldn't eat them and had to send them back to the Earth. The next year, after scientists made sure they were safe, the spacemen grew a second crop. This time the vegetables were ready for the spacemen to eat.
Gardening is different in space than it is on Earth. Without gravity, plants don't know which way is up. But they learn how to grow. They send their leaves in the direction of light and their roots into the soil.
The spacemen also have grown vegetables as well as flowers. It's important to know a plant can flower in space, because flowering is part of how some plants make fruit.
While the space garden is small for now, hopefully it could one day help provide people with food on long-time space trips.

Mars is an empty planet, but that could change. Someday, it might have farms where fruit and vegetables could grow.
Growing food on Mars has always seemed hard. But scientists think they have found a way to do it. They put sheets (薄膜) of material on the ground. The sheets could change the cold, dry planet into land for farming. Robin Wordsworth worked on the sheets at Harvard University in a Massachusetts. He said the sheets could let people live on another planet. On Mars, the conditions are not good, though. Most importantly, the planet is cold and dry. The soil might have polluted parts, and the air does not have much nitrogen (氮气) that plants need to grow.
The sheets do not solve all the problems. Still, they could help to set up a place for plants. The plants would grow only under the sheets. So there is less worry about harming the rest of Mars. The sheets would cover the plants.
The scientists worked with sheets about an inch thick. Those allowed light through for plants. They also warmed the ground and trapped enough heat to melt ice on Mars. Placing the sheets over icy parts of Mars could let plants alive there. Their study was printed in Nature Astronomy. The sheets could be on the ground to grow water plants and they also could be hung. That would give room to plants to grow on land below them.
Wordsworth said, "You can imagine this being used in a number of ways. It could be used for visitors to Mars. Later it could be for people who live there. However, it's a pity that the sheets are being studied in the lab."

8 . Stop reading for a minute and think about what you see when you look up at the sky on a clear night. You probably see many stars. Long long ago, farmers watched some stars to know when to plant their crops. Travelers did so to find their way in the dark.
Today stars are still important to some people. Scientists find that most stars are very big. Actually, some stars are so far away that it would take millions of years to get to them even by spaceship. Another thing we know today about stars is that some are made up of (由…组成) hot gases (气体). The gases are so hot that they send out light. If you watch a star carefully, you may notice that it twinkles (闪烁) sometimes. As you may understand, light from a star must shine through the air before you can see the star. Air is always moving, it makes light from the star move back and forth. When the light moves, it makes the star twinkle. Stars also have different colors. The colors of a star depend on how hot it is. To our surprise, the cool stars are red and the hottest stars are white.

A trip to space
by Jerry
10 October, 2017
I’m so happy! Tomorrow I’ll be one of the first students to travel into space. The spaceship will leave the Earth at 9 a.m. It’ll take us to the Moon. I can’t wait.
The Moon is around 380,000 kilometers from the Earth, so it’ll take us about four days to get there. There’s no gravity in space, so we’ll all be able to float around in the spaceship. We’ll have to tie ourselves to our beds so that we won’t float away in our sleep! Without gravity, our bodies may get weak, so we’ll have to do exercise every day.
When we arrive, I’m going to walk on the Moon. I’ll have to wear a spacesuit to help me breathe because there’s no air on the Moon. I’ m going to take as many photos as I can, that is, if my camera still works up there well.
1. How did Jerry feel about his trip to space?2. When did the spaceship leave the Earth?
3. Why did Jerry have to wear a spacesuit on the Moon?
4. How far is the Moon from the Earth?
5. There was no gravity in space, was there?
