请找出下列第2和第3段的主题句 1 There are two things I have always wanted to do -- write and live on a farm. Today I'm doing both. I am not in E. B. White's class as a writer or in my neighbors' league as a farmer, but I'm getting by. And after years of frustration with city and suburban living, my wife Sandy and I have finally found contentment here in the country. 2. It's a self-reliant sort of life. We grow nearly all of our fruits and vegetables. Our hens keep us in eggs, with several dozen left over to sell each week. Our bees provide us with honey, and we cut enough wood to just about make it through the heating season. 3. It's a satisfying life too. In the summer we canoe on the river, go picnicking in the woods and take long bicycle rides. In the winter we ski and skate. We get excited about sunsets. We love the smell of the earth warming and the sound of cattle lowing. We watch for hawks in the sky and deer in the cornfields.
