    195 countries reached an agreement(协议) on Dec. 12, 2015 after two weeks' talks in Paris. They talked about climate(气候) change. It is the first time in history that most of the world's countries, rich or poor, promised to take action to deal with climate problems.

    Below is a chart showing where the greenhouse gas(温室气体) comes from.

Where is greenhouse gas from?

    The Paris Agreement(巴黎协定) sets up a goal of cutting down the earth temperature to less than 2℃. If the warming gets above 2℃， there will be serious problems on the earth like natural disasters.

The agreement also asks countries to volunteer to do things. For developed countries, they will do even more. They have a plan to offer over 100 billion dollars to help poorer countries to develop clean energy like water and wind power.

    However, the Paris Agreement won't solve earth warming by itself. The future also depends on how well each country will carry out their promises.

    Life in the future will be very different from life today. What will the change(变化)be? There will be changes in our food. Maybe(或许)no one will eat meat every day. They will eat fruit and vegetables. Computers will be very small, and there will be at least(至少)one in every home. People will take the computers in their pockets. Work in the future will be different, too. Robots will do dangerous and hard work. People will have more free time to travel.

    Many parents fear to travel with kids. If you have the same fear, it's time to remove it. Here are some reasons why it's important to travel with kids.

    When I say that, I'm talking not only about the history lessons. I'm also talking about the math lying behind the questions to be answered, such as "How long will it take us to get there? What is the currency (货币) exchange rate to the US dollar? Children can also learn some geography facts."

    For kids, being able to talk about their travel experiences with others is pretty impressive! These types of travel experiences stick with children for a lifetime, and they will always have information to share about their travels.

    The moment my son became old enough to travel alone, I was so nervous. But it didn't take him long to become a very independent little traveler. When children realize what it takes to travel independently, it creates a certain level of confidence which is very important for them.

    Once your kids realize that there's so much of this exciting world that they haven't seen, they will be hungry to explore more and more!

    Who doesn't need a break from school? I know my kids do because we are strict during the school week: No TV, no computers, only homework and after-school activities. So, naturally, they want a break from the busy life. And, more than likely, there is plenty of fun waiting for you. Don't forget that you don't have to travel far for kids to have a good time!

    Four good friends Mouse, Crow, Turtle and Deer lived in the forest. Every day they met at the lake and told each other interesting stories.

    One day Deer did not come to the lake to drink water.

    The other three were worried.

    "I saw a hunter (猎人) in the forest this morning," said Crow. "I'm afraid Deer might be hurt."

    "Fly over the forest, Crow," said Mouse. "Please see if you can find our friend Deer."

    It took him a few minutes before Crow saw Deer caught in a trap (陷阱) made of ropes. He flew back right away to ask the other two for help. When they arrived, Mouse and Crow began to break the ropes. Turtle kept talking to Deer to help her feel better.

    Just then, the hunter came to check his trap. "Everyone, leave now," said Turtle.

    Deer at once ran away with Mouse. Turtle just lifted a foot up when the hunter got close.

    "My trap is empty," said the hunter. "But, a turtle is better than nothing. I will eat turtle soup tonight." The hunter picked Turtle up and started for home.

    "Now we all must help our friend Turtle," said Deer.

    Deer lay down on the way. She seemed dead. Crow flew and landed on Deer's head. The hunter saw Deer so he put Turtle down to get Deer. As soon as the hunter left Turtle, Mouse ran up and helped Turtle hide in the forest. Deer jumped up and ran off .The hunter went back to get Turtle, but he found him gone. "How scary! There is magic here," he said to himself in great fear. Then he rushed out of the forest and never came back again.

    There was magic in the forest that day. That magic was called friendship.
