Did you ever think someone was scary (恐怖的)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 celebrate 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.

These days, young children can enjoy directly what it is like to be a marine biologist (海洋生物学家) at a marine association. What they discover can lead them to appreciate and protect the ocean and also the animals living in it.
At the present time, learning isn’t only limited to the classroom. It’s quite common for kids to learn from outdoor experiences. Teachers commonly take their pupils on field trips to museums as well as other interesting areas. If you wish to help pupils to take care of the ocean, one of the best areas to take them to is a marine association, the place where the ocean biome (生物圈) is shown.
Taking your pupils to a marine association is a prefect way to help them learn. Education professionals agree that there are topics that children can learn more successfully whenever they experience them directly.
Several organizations that focused on protecting the ocean now operate on the coast of different areas in America and all around the world. It’s quite common for marine associations nowadays to open their doors several times a week to kids, parents, and ocean lovers to learn more about the ocean biome.
A marine association has different programs for children of different ages. You’ll find programs that are developed specially for pupils. Pupils are involved in interactive (互动的) learning. This learning experience allows young children to recognize the value of the role each species performs in their environment. They not only get to research creatures from the ocean, but they also get to see, touch, and smell most of these animals and plants. This type of exposure offers students an idea about the life of a marine scientist. It could help them choose a career afterwards.
These programs are generally held on Saturdays and Sundays in order that kids and parents can have more hours in which to have fun. Teachers who want to arrange these activities for their students can call a local marine association near them.
