We know that trees are useful in our everyday life. They give us 1 things, such as wood, oxygen, rubber（橡胶）, medicines 2 many other things. They can also tell us a lot about our climate. The following are the reasons. If you cut 348 a tree, you can see that it has many rings. Most trees grow one new ring 4 year. Because of this, we know how old a tree is. A tree over a hundred 5 means that it has more than a hundred 6 . When the climate is dry or very cold, the trees do not grow very much and their rings 7 usually thin. When it is wet and warm, the rings
8 thicker. If the rings are suddenly very thin or suddenly very thick, it means that the 9 changed suddenly. If we look at the rings on the tree, we can learn about the climate in the past years. We can see

I was tired and hungry after a long day of work. When I walked into the living-room, my 12-year-old son looked up at me and said, “I 31 you.” I did not know 32 to say, and I just stood there, looking 33at him. My first thought was that he must need help with his homework. Then I asked, “What was that all about ?” “Nothing,” he said, “My teacher said we should tell our parents we love them and see what they say.”
The next day I called his teacher to 34 more about what my son said and how the other parents had reacted﹡. “Most of the fathers had the 35 response﹡ as you did,” the teacher said, ”When I first suggested ﹡that we try this, I asked the children what they thought their parents would say. Some of them thought their parents would be surprised.”
Then the teacher explained , “ I want my students to know that feeling love is an important part of 36 . I’m trying to tell them it’s too bad that we don’t express﹡ our feelings. A boy 37 tell his parents he loves them.” The teacher understands that sometimes it is 38 for some of us to say something .
That evening when my son came to me, I took him in my arms and held on for a while, saying, “Hey, I love you, 39 .” I don’t know if saying that made either of us healthier, 40 I did feel pretty good.
