    My friend Bob has a large police dog named Jack. Every Sunday afternoon, Bob and Jack have a walk in the park near their home. Jack likes these walks very much.

    On a cold Sunday afternoon, I go to Bob's home. Bob is happy to see me. At first Jack is happy too. Bob and I talk for a long time. Jack plays with a ball in the room for some time. Then he sits down in front of me and looks at me. I go on talking with Bob. Just at that time, Jack takes my hat and runs out of the room. I go after him to get my hat back. Suddenly, I know what Jack wants to do.

What a clever dog!

    Have you ever planted a few trees on Tree Planting Day? Each year, millions of people, both 1 , plant a lot of trees. But this may not be the best way to make your home a 2 place.

    Last week we visited a park in Hebei. We were 3 to find most of the trees had been burned. The workers told us that the trees 4 soon after they were planted because they weren't watered well enough. 5 workers burned them and cleaned the place for 6 trees to be planted this year. 7 a card found in one of the dead trees, a student wrote,“ I hope this tree will grow up with me to 8 the backbone (栋梁) of our country.” The workers said that the survival(存活) of the trees was really more important than 9 trees were planted.

    Some people in Beijing now have a new idea that they can donate (捐赠) some money and let professionals (专业人士) plant and 10 the trees.
