Example Input: Article: Did you ever think someone was scary because they looked different or ate strange food? Well, they might think the same about you! One of the things we all need to do is to _ variety.We shouldn't think badly of people from other cultures because they behave differently from us. Sometimes we treat people from other countries unfairly, because one person from that culture did something bad.Well, has your class ever been punished just because a few kids were causing trouble? Has your whole family ever been blamed for something your little sister did? It doesn't seem fair, does it? It's just equally unfair to blame a whole culture for what two or three people have done. So here are some things that you can do to help yourself understand other cultures: 1Find common ground! Just remember that even though some people look different on the outside, that doesn't change how they are on the inside.They still have the exact same feelings! 2 _ Because someone from another culture has been mean to you, you decide to avoid everyone from that culture.Well think about it.Why are you blaming them for something they didn't have anything to do with? Put yourself in their shoes.How would you feel? Putting yourself inside someone else's head can be a very powerful way to understand WHY they are acting the way they are. 3Try to make friends with people from other cultures! You could ask them about their culture, or what it is like in their country, if they can remember, or if they have ever lived there.Try foods from their culture, or ask them about words in their language.You might be surprised at how interesting other cultures can be! You can join great discussion groups, participate in projects, and have lots of fun doing new things. 4Be aware that you've judged other people If you know what you have done, it helps to make things better.Pay attention to what you think about other people.It helps.

Example Input: Article: Many people say dolphins are very intelligent. They seem to be able think, understand, and learn things quickly. But they are smart like humans or more like cats or dogs? Dolphins use their brains differently from people. But scientists say dolphin intelligence and human intelligence are alike in some ways. How? FACT 1: Talk to Me Like humans, every dolphin has its own "name". The name is a special whistle . Each dolphin chooses a specific whistle for itself, usually by its first birthday. Actually, scientists think dolphins, like people, "talk" to each other about a lot of things, such as their age, their feelings, or finding food. And, like humans dolphins use a system of sounds and body language to communicate. But understanding their conversations is not easy for humans. No one "speaks dolphin" yet, but some scientists are trying to learn. FACT 2: Let's Play Dolphins are also social animals. They live in groups called pods, and they often join others from different pods to play games and have fun ---just like people. In fact, playing together is something only intelligent animals do. FACT 3: Fishermen's Helpers Dolphins and humans are similar in another way: both make plans to get something they want. In the sea of southern Brazil, for example, dolphins use a interesting strategy to get food. When fish are near a boat, dolphins signal to the fishermen to put their nets in the water. Using this method, the men can catch a lot of fish. What is the advantage for the dolphins? Why do they assist the men? The dolphins get to eat some of the fish.

Example Input: Article: If you could leave a farewell video for your loved ones that they'd see only if you died, would you do it? I think I would. I read about an app that helps people create a video to be published on a social-networking site only after death. Of course you don't need an app since it's easy to make your own video with smartphones, laptops and computers. But how many people do you know who would actually go ahead and leave "If I die" footage ? My father died unexpectedly on Christmas Eve three years ago and I've since longed for one more time to talk to him and hear his voice. Imagine if he had left such a video. I would see him again, hear his laughter and benefit from his parting words and advice. I don't think people, unless they have a terminal illness, go through life thinking they'd better leave a video in case of an _ death. But it is an opportunity to say all the things you want to say before it's too late. Still, some say that such a video robs loved ones of their own memories of you. Any special images they have would be superimposed by the video image you've created. Others think it's scaring and might be tempting fate. I expect my video would consist of reminders to my children: Be safe; be[:++Z+X+X+K]mindful of your surroundings; exercise good judgment; speak up; it never hurts to ask; don't waste time and "call when you get there". And in addition, I would repeat what I always tell them: I need to know where you are, every-step-of-the-way. That would make them laugh. Readers, would you find comfort in knowing you've said your farewells and left something concrete for your loved ones? What messages would you leave for family and friends?
