Think about the different ways that people use the wind. You can use it to fly a kite or to sail a boat. Wind is one of our cleanest and richest power sources（来源）, as well as one of the oldest. Evidence shows that windmills（风车）began to be used in ancient Iran back in the seventh century BC. They were first introduced to Europe during the 1100s, when armies returned from the Middle East with knowledge of using wind power.

For many centuries, people used windmills to grind（磨碎）wheat into flour or pump water from deep underground. When electricity was discovered in the late 1800s, people living in remote areas began to use them to produce electricity. This allowed them to have electric lights and radio. However, by the 1940s, when electricity was available to people in almost all areas of the United States, windmills were rarely used.

During the 1970s, people started becoming concerned about the pollution that is created when coal and gas are burned to produce electricity. People also realized that the supply of coal and gas would not last forever. Then, wind was rediscovered, though it means higher costs. Today, there is a global movement to supply more and more of our electricity through the use of wind.

I’ve loved my mother’s desk since I was just tall enough to see above the top of it as mother sat doing letters. Standing by her chair, looking at the ink bottle, pens,   and white paper, I decided that the act of writing must be the more wonderful thing in the world.

Years later, during her final illness, mother kept different things for my sister  and brother. “But the desk,” she’d said again, “it’s for Elizabeth. ”

I never saw her angry, never saw her cry. I knew she loved me; she showed it in action. But as a young girl, I wanted heart-to-heart talks between mother and    daughter.

They never happened. And a gulf opened between us. I was “too emotional(易动感情的)”. But she lived “on the surface(表面)”.

As years passed I had my own family. I loved my mother and thanked her for our happy family. I wrote to her in careful words and asked her to let me know in any way she chose that she did forgive(原谅) me.

I posted the letter and waited for her answer. None came.

My hope turned to disappointment(失望), then little interest and, finally, peace— it seemed that nothing happened. I couldn’t be sure that the letter had even got to mother. I only knew that I had written it, and I could stop trying to make her into someone she was not.

Now the present of her desk told, as she’d never been able to, that she was    pleased that writing was my chosen work. I cleaned the desk carefully and found    some papers inside —a photo of my father and a one-page letter, folded(折叠) and refolded many times.

Give me an answer, my letter asks, in any way you choose. Mother, you always chose the act that speaks louder than words.
