SPACE is a lonely place. Hundreds of thousands of kilometers from home, astronauts have a hard life. 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 (气人的). Sometimes, things get even weirder(更怪异的). 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.

Have you heard of the term “etiquette” And do you know that etiquette is not only a useful word 46 very useful to understand?

Etiquette is not the same in every culture 47 in every situation. For example, standing very close to the person you are talking with is quite common in some Asian countries. However; if you do this in Europe, some 48 people might feel 49.Even in China, we all know that etiquette is not the same in all situations. Perhaps we think that talking loudly in our own homes is fine, but there are other places where talking loudly is 50 .For example ,most people would agree that talking loudly in a library, a museum, or a movie theater is 51 .Even if you are with your friends, it is better to keep your voice 52 in public places. In fact, we should also 53 not to cough or sneeze loudly in public.

If we see someone 54 the rules of etiquette, we may politely give them some suggestions. Perhaps one of the most polite ways 55 ask someone, Would you mind doing this or Would you mindnot doing that. For example, if someone cuts 56 you in a line, you could ask them, Sorry, would you mind 57 the line? If someone is smoking on the bus you could ask, Excuse me, could you please 58 that cigarette? People don’t usually like 59 , so we have to be careful how we do this.

Although rules of etiquette can often be different, some rules are the same almost everywhere in the world! For example, 60 is almost never allowed. If you see someone you know doing this, you can ask them, Would you mind picking it up?
