    You can find out many things about a tree by studying its rings.

     Each year, from top to bottom, a tree grows a new layer (层) of wood around itself. If you cut across a

tree trunk or branches, you would see that these layers of wood look like rings. By counting tree rings, you

can tell how old the tree is. If you count ten rings, for example, the tree is ten years old.

    Looking at the picture shown above, you can see that each tree ring has a dark part and a light part. The

light part wood grows in the spring, the dark part wood in winter. Look also, that some rings in the picture

are wide and others are narrow (窄). Trees grow aide rings during the years when they get a lot of water and

sun-light. By examining tree rings, you can tell what the weather may was like many years ago.

    Giant sequoia (红杉) trees, such as the one in the photo above, grow in north-western California. Some of
