阅读材料，回答题。Home Schooling All children in the United States have to receive an education, but the law does not say they have to be educated at school. A number of parents prefer not to send their children to school,46There are about 300,000 home-schoolers in the United States today. Some parents prefer teaching their children at home because they do not believe that public schools teach the correct religious values; others believe they can provide a better educational experience for their children by teaching them at home.47David Guterson and his wife teach their three children at home. Guterson says that his children learn very differently from children in school.48For example, when there is heavy snowfall on a winter day, it maystart a discussion or reading about climate, snow removal ( 去除) equipment, Alaska, polai bears (北极熊) ,and winter tourism.A spring evening when the family is out watching the stars is a good time to ask questions about satellites and the space program49
Home schooling is often more interesting than regular schools, but critics say that home-schooled are outsiders who might be uncomfortable mixing with other people in adult life.50However, most parents don't have the time or the desire to teach their children at home, so schools will continue to be where most children get their formal education.
