I love it at night. It’s peaceful. And when it cools down I sometimes do some ironing. I don’t really care for it. I work full-time and I am too busy for most housework. I remember the old woman who taught me to iron. I was about 15 and I had to get a job taking care of a woman to make a living. She had been an able-bodied, healthy woman until the accident that caused her to be paralyzed(瘫痪的).
The woman sat in an electric wheelchair all day. She could only move her head and arms. She would tell me how to do things. She would teach me in great details on the correct ways to do things. Her home was perfect and beautiful. She would follow me around in her electric wheelchair to make sure I did everything exactly right. I’m sure she had been a perfect homemaker. She would have me fold everything, including socks. I would complain silently and wish terrible things on her. She taught me the right way to make the bed. I know sometimes she’d get frustrated(沮丧) and impatient with me. I knew she wanted to do it herself. But she never shouted at or blamed me. She only insisted I do it right. I didn’t like it much, but I did it.
Today I can iron pretty well. I know where to start on a shirt and the right way to do the trousers. Now when I think about it, I don’t think she is an old lady. I think she might have been about my age now. Anyway, when I iron, I think of her and silently thank her for all the things I learned.

Photosynthesis(光合作用) appears when a tree uses the sunlight and chlorophyll(叶绿素) to make glucose(葡萄糖). The tree needs to eat the glucose to grow, and we know it is eating because the leaves are turning green. It is not the glucose but chlorophyll that turns the leaves green.
Trees grow the most in spring and summer, when there is a lot of sunshine every day. When fall begins, days grow shorter and there is less sun. That makes trees begin getting ready for winter. Leaves begin to turn red, orange, gold, and brown, because with less sunlight and water for photosynthesis, the green chlorophyll begins to disappear.
The leaf colors we see in autumn have been in leaves all along, but with so much chlorophyll, we can’t see them until the chlorophyll is gone. As winter comes, the tree uses the food it has stored during spring and summer, and goes into a rest period (时期). Actually, trees hibernate just like bears! The only difference is that bears lie down in a cave to sleep, and trees lose all their leaves and stand up to sleep.
