It stands to reason that, once in a while, they need to have a good cry. But this is a lot harder than it sounds. We still know very little about space, and about living in zero gravity. In fact, we are discovering new things every time astronauts take to the skies (and beyond). As The Atlantic reported in January, crying is not all that simple in space. This is because when a person normally cries, gravity makes their tears move downwards. But in a spacecraft, this is not the case. Here, there is no gravity, which is why we so often see pictures of astronauts floating around. This means that, strangely, when you cry your tears have nowhere to go. As a result, they just stick to your eyes. In May 2011, astronaut Andrew Feustel experienced this. "Tears," as he said, "don't fall off your eye... they just kind of stay there. " This can be quite painful. In space, your eyes get very dry, and the added moisture is irritating . Sometimes, things get even weirder . The astronaut Ron Parise told The Atlantic that when tears get big enough, they "break free of the eye and float around". No one can be quite sure why we cry. Why should water in our eyes have anything to do with feeling sad? If you stop to think about it, crying is a very strange thing indeed. And now, thanks to the wonders of space, it just got even stranger.

Please answer this: Write a multi-choice question for the following article: Article: My grandfather is 70 years old this year. He is in good condition but he lost his hearing at the age of 65. Then it became difficult for me to communicate with him. My mother bought a hearing aid for him, but he often forgot where he had put it. So my mother advised me to communicate with him by gesture. Good idea! And then I began to use gesture. When I wanted to have an apple, firstly, I pointed to my mouth; later I made my hands form a round shape. Then he gave me an apple. When I was hungry, I pointed to my stomach. He would go into the kitchen and cook for me. When I wanted to use, the computer, I pointed to it. If he nodded , I could play computer games from 8 pm to 10 pm; if he disagreed, he always touched my head and pointed to the desk -- that meant that I should do my homework first. It was an easy way for us to communicate with each other!

Please answer this: Write a multi-choice question for the following article: Article: Not all memories are sweet. Some people spend all their lives trying to forget bad experiences. Wars and traffic accidents can leave people with terrible physical and mental _ Often they appear again in dreams. Now American researchers think they are close to developing a pill , which will help people forget bad memories. The pill is designed to be taken immediately after a frightening experience. They hope it might reduce , or possibly erase the effect of sad memories. In November, some scientists tested a drug on people in the US and France. The drug stops the body producing chemicals that fix memories in the brain. So far the research has suggested that only the mental effects of memories may be reduced, not that the memories are erased. The research has caused plenty of argument. Some think it is a bad idea, while others support it. Supporters say it could lead to pills that prevent or treat soldiers' troubling memories after war. They say that there are many people who suffer from terrible memories. "Some memories can destroy people's lives. They come back to you when you don't want to have them in a dream. They usually come with very sad feeling." said Roger Pitman, a scientist of psychiatry at Harvard Medical School. "This could relieve a lot of that suffering." But those who are against the research say that it is very dangerous to change memories because memories give us our identity . They also help us all get away from the mistakes of the past. "All of us can think of bad events in our lives that were terrible at the time but make us who we are. I'm not sure we want to erase those memories," said Rebecca Dresser.
