Example Input: Article: Although most people know there are Seven Wonders in the Ancient world, only few people can name them. This is because most of them are no longer there except the pyramids. However, there is a growing list of wonders of the world today. About nine years ago, UNESCO's World Cultural and Nature Heritage List had 411 places and 136 countries were responsible to protect them, and the list keeps on growing. Usually it is the task of a group of 21 experts to decide which places go on the list. The experts are chosen to work for six years. Their work is to examine and discuss the suggestions from different countries. They also manage the World Heritage Fund which can offer help to countries for protection work. Over the past centuries a lot of cultural or historic places have been destroyed by man or nature. Protecting our natural and cultural heritage is a long and difficult task. Earthquakes, floods, pollution, wars, or even tourism are some of the dangers that harm the heritage. When a historic place is in great danger, it is put on the World Heritage in Danger List and necessary things will be done to protect it. Places which are on the danger list include Historic Bridges of Indiana, St. Elizabeth's Hospital, Rosenwald School in Southern U.S., etc.

Example Input: Article: Whales live in the ocean, but they are not fish. They are warm-blooded mammals and must have air to breathe. The babies are born alive and drink milk from the mother's body. It took millions of years for the whale to develop as it is today. Every spring groups of whales swim hundreds of kilometers to warm places to bear their young. Each group goes to the same place every year. The mothers take very good care of their babies. The fully grown whales are very gentle and playful with each other, and with humans. They "talk" to each other with a high noise that sounds beautiful. This"talking" can be heard for more than 300 kilometers in open waters. Yet humans kill over a hundred whales a day. They kill them to make whale oils and a lot of other things. Killing them is a modern business with modern machines and even harpoons( ) that explode( ) inside the whales. A whale dies very slowly and in great pain. Some ships kill every whale they can find, even the mothers and babies. Then there are no young whales to grow up or to bear more young.

Example Input: Article: One of the greatest sources of unhappiness, in my experience, is the difficulty we have in accepting things as they are. When we see something we don't like, we wish it could be different. We cry out for something better. That may be human nature,or perhaps it's something ingrained in our culture. The root of the unhappiness isn't necessarily that we want things to be different.However, it's that we decided we didn't like it in the first place. We've judged it as bad,rather than saying, "It's not bad or good, and it just is it." In one of my books, I said, "You should expect people to mess up and expect things to go differently than you planned". Some readers said it's too sorrowful to expect things to go wrong.However, it's only negative if you see it as negative and judge it as bad. Instead,you could accept it as the way the world works and try to understand why that is. This can be applied to whatever you do:how other people act at work,how politics works and how depressing the news media can be.Accept these things as they are,and try to understand why they're that way. _ will save you a lot of sadness,because you'll no longer say, "Oh, I wish bad things didn't happen!'' Does it mean you can never change things? Not at all. But change things not because you can't accept things as they are, but because you enjoy the process of changing, learning and growing. Can we make this world a better place? You can say that you'll continue to try to do things to help others, to grow as a person, to make a difference in this world. That's the correct path you choose to take,because you enjoy that path. Therefore, when you find yourself judging and wishing for difference, try a different approach: accept, and understand. It might lead to some interesting results.
