Conserving energy and resources is very benifical for human life and nature. Human damage many nature things while making energy and resources for their daily use. For example deforestation, use of water to make electricity, which can decrease the ammount of aquatic animals and water on the earth. Some buisness have adopted the idea of a four-day work week so they can conserve energy and resources. A four-day work week can also effect on thier buisness and put them in loss but it depends on them how they manage their work in four days. But Should schools follow this model by extending the school day two hours and make a four day school week? In my opinion school shouldn't follow this model. student's already have five- day school week which sometime seems very short, when students have lot of work to do and they need more help of teachers. In a month there are some federal holidays in weekdays, Which make a five- day school week more short. Extending the school day two hour and adopted a four-day work week have many disadavtages. It can put bad impact on students study and on thier grades, they will spend their weekend more with friends not with books, Students may spend their times on computer games and on phones. So, four-day school week will effect somewhere in student life. It's better to keep the five-days school week for students goods and for their better education.  Every student study hard in school to get better grades in all classes. Student's always try to learn more from their teachers and do their best in class. But a short week can a put bad impact on their study and their grades will go down. For example when students have an extra time in their classes, they mostly spend it with thier teachers and asking them questions so they can get answers in a specific way. But what if they don't have time in class or teacher's don't have time for student's. If a teacher has a short time to teach soemthing. They will teach in a very fast or a different way to students. Some student's may not get everything in class, and their class performance will go down and it impact on their grades. It's very important for a teacher to spend a time with their students and ask them about their problems in classes, and also for a students it's very important to share their problems with teacher so, they can find a way to solve the problems. It can only happens when student and teacher both have time in class to discuss. so the Four-day week can make a distance between a teacher and a student.  Second, Friendship is a very important thing in every person life, Friendship with a good friend can tell you the path of your success. Spending time with friends is a good habbit. But it doesn't mean that you have to spend you al free time with friends. Almost every studnt spend their weekends with their freinds and they dont care about school study. Even we spend our one school holidays with friends and forget about study. what if we have three days off in a week. Do we spend that time with our books? the answers is no we cannot spend time with books on weekends. We need to spend our times with books and the schhol is the only place where we can learn something and soend times with the books. For example Last week we had an five d
