We know that trees are useful in our everyday life. They give us   1  things, such as wood, oxygen, rubber（橡膠）, 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
  10  changing today.

The marathon(馬拉松) in my town usually takes place in hot weather. My job was to follow the runners to help those who needed medical help. “We should stay behind the last runner, so take it slowly,” I said to the driver, Doug.
As it began, the front runners started to disappear(消失). Then I noticed a woman in blue running shorts and a white T-shirt. “ Doug, look!” We knew we were watching our “l(fā)ast runner”. Her feet turned in , yet her left knee turned out. Her legs were so crippled(畸形的) that it seemed impossible for her to be able to walk. How could she run a marathon？
We watched in silence as she slowly moved forward. We would move forward a little bit, then stop and wait for her. Then we would slowly move forward a little bit more. As I watched her try to put one foot in front of the other, I found myself breathing for her. I wanted her to stop, and at the same time, I hoped that she wouldn’t. Finally, she was the only runner left in sight. When the finishing line came into sight, we found the cheering people had all gone home. She slowly crossed through the line and lifted her hands, full of happiness.
I do not know the woman’s name, but since that day she has become a part of my life. For her, it was about finishing what she had set out to do, no matter what. When I think things are too difficult and want to say “I just can’t do it”, I think of the last runner. Then I realize how easy the task before me really is.
小題1:When does the marathon usually take place in the writer’s town？
A．In spring. B．In summer.C．In autumn.D．In winter.
小題2:The last runner had problems with her      .
A．headB．backC．legsD．a(chǎn)rms
小題3:Why did the woman take part in the marathon?
A．To win a good prize
B．To beat the other runners
C．To make friends with others
D．To finish what she had decided to do
