It is often a complex and tiring task to live a healthy life, but that isnˈt always the case. Itˈs time to change the classroom environment for the health of the children.
Itˈs not surprising that sitting for long as a child is associated with health problems as an adult. Fortunately, thereˈs a simple, overlooked solution to these problems—standing desks.
Over the last few years, a number of studies have shown that the benefits of the increased range of movement students experience when using standing desks are surprisingly broad. Besides, standing desks encourage higher levels of teamwork and participation among students. Standing desks also help to reduce the risk of some diseases. They can help to prevent fatness, heart disease and low spirits. Sedentary（久坐的）lifestyles are a major reason why teenagers suffer from poor mental health, while higher activity levels reduce the chances of a child experiencing such an illness.
The benefits of bringing standing desks into classrooms are obvious. Otherwise they will likely hurt their muscles when standing for a long time. Standing desks usually offer a full range of motion, which includes the option to sit or lean（倾斜身体）without losing eye-level of the rest of the class, and that full range of motion is important.
Sitting isnˈt horrible. It isnˈt a thing we should never do. The problem is that we do it too much, and so do our children, which makes children less likely to succeed and keep healthy.
A．It is time for us to stand up to stay healthy.
B．But it is important for children to use them gradually.
C．Children spend most of their school day sitting at desks.
D．Thus itˈs necessary to break up the sitting with standing desks.
E．Something as cheap as a desk could be making a major difference.
F．Right now there is something we can do easily to keep our children healthy.
G．For example, they help students keep fit and avoid putting on too much weight.
