In space, there is no up or down. Without the gravity that we experience on Earth, as-tronauts and everything else on a spaceship float freely.
Humans can experience the sense of zero gravity without going into space. How？A zero-gravity flight. When an airplane flies in a lot of parabolas（抛物线）, a man-made zero-gravity environment is set up. Everything in the plane floats, even passengers.
Gravity has an effect on everything from the human body and mind to the behavior of plants and the way machines run. Space travel is expensive and dangerous. But zero-gravity flights let scientists conduct experiments in an environment that mimics（模拟） the conditions of space. On each of its research trip, Zero-G flies about 30 parabolas, each of which creates a period of weightlessness that lasts about 30 seconds. Nikolaus Kuhn of the University of Ba-sel, in Switzerland, flew with Zero-G. He was conducting an experiment about soil and the flow of water on Mars. The Red Planet has about one-third of the gravity that Earth has. This means water flows more slowly on Mars. By making the parabolas less steep, zero-gravity flights can make the feeling of Martian gravity. Flying with Zero-G has been necessary for Kuhn’s research. “It is the only chance, other than going to Mars, to mimic movement of water as it would be on Mars,” he told TFK.
For years, NASA used zero-gravity flights to prepare and train astronauts. “I have not been to space,” Peters of Zero-G says, “But I have been told by astronauts that zero-gravity feels exactly the same.” As humans continue to explore the universe beyond Planet Earth, zero-gravity flights will remain an important and fun tool. “It never gets old,” Peters says “I would do it every weekend for the rest of my life if I could.”

Many people don’t have a home because of an illness or because they lost their jobs. They have bad health and can’t start working, and because of that, they can’t pay for a doctor, so it’s a never-ending circle. Homeless people don’t have anywhere to go, so they have to sleep on the streets, covering themselves with newspapers and looking through the rubbish cans to find some food or warmer clothes.
Seeing these horrible living conditions, the Australian charity Beddown decided to help these people in need. They came up with an amazing idea to make shelters in places that are vacant at night-like parking lots! The organization asked one of the largest car park-opera tors, Secure Parking, and they agreed upon it.
“It was great to start with a group of our volunteers to help us and set up some beds. Although as expected we had a few challenges to overcome, it was good to start bringing Bed down to life. Beddown will provide an immediate response for those who can not sleep well to access safe, find shelter-and access to a real bed and a great night’s sleep. We will work with our other partners to provide long-term solutions to providing our guests with accommoda-tion, education and employment opportunities.” The founders of Beddown said in one of their Instagram posts.
The charity also provided other services to the guests, like doctors, nurses, dentists, hairdressers. They gave them new clothing, a place to clean themselves and helped provide social services. “After spending the week here, having a good sleep at night, it reminded me of life and I want to begin my life again,” one homeless man said.

4.What can be the best title for the text？

It often happens that problems blow into our lives. For some of us it may be a temporary period, but for others, it’s a lifetime change. Here are stories of ordinary people who had to face unpleasant events and managed to overcome them with dignity.
Bill Porter

Evgeny Smirnov
There’s nothing worse for a dancer than losing the ability to dance. But Evgeny Smirnov, Russian break dance champion, went on dancing, despite the fact that he had to learn to dance again. His performance became a great example of the fact that someone can dance incredibly cool even without a leg.
Olesya Vladykina
Even though she’s only 20, Olesya Vladykina has suffered a lot; an accident in Thailand took not only her left hand, but also her close friend.

As Grandma gets older, she is getting more and more forgetful. I went to a nearby supermarket with her on last week. I pushed the shopping cart around to load it with what we want to buy. I was looking at some snacks while I realized Grandma was missed. I looked for her everywhere and she was nowhere to be found. So I turned to security guard who was on duty with tear in my eyes. He comforted me patient and told me to wait by the apple stand when she and other guards were searching for Grandma. It was not long before Grandma was found and brought to me. I was very grateful that I decided to put it forward and help others whenever possible.
