Some students are amused by something else. They spend all their time looking anywhere but at me. Then again, some students’ favourite activity is     1    . With their chins on their hands, they occupy themselves by     2     out of the window or up at the ceiling. They are certainly interested in something, but who knows what. The main thing is reminding     3     students that they need to pay attention in class.

While it is easy to perceive when students are interested, bored, or distracted, it is sometimes much harder to     4     when students are troubled. Students who are angry, afraid, or experiencing     5     may have their arms crossed in front of their chests and their legs closed or crossed, like they are guarding their bodies. Students who are sad or worried will nearly always wear a     6    . They may also hide their faces in their hands like they are     7     or ashamed. Some students act this way merely because they are afraid of being called on by the teacher. However, if a student does not     8     to brush her hair and her eyes are red from weeping, then I can infer that there are deeper issues at work. It could be that she is having serious     9     with other students or at home. Whatever it is, I know I need to     10     and assess what is going on.

Beyond this, you can keep healthy by     1     different categories of fresh foods, especially fruit and vegetables, which are full of vitamins and     2    , rather than processed foods. Processed foods often contain less nutrition, and have higher     3     of sugar, salt, and fat than fresh ingredients. Besides this, it is also important to have some meat, beans, or dairy products in your diet, as they     4     the necessary protein for strong bones and muscle     5    . As with everything in life, moderation is key. The     6     diet is a balanced one, without too much or too little of any one thing. 

Finally, a     7     key to healthy eating is to eat slowly. It takes about twenty minutes from the time you start eating for your brain to tell your body that you are full. What this means is that people who     8     too quickly end up eating too much food because they still feel hungry. Eating slowly also allows your body to     9     your food better, and will allow you to enjoy your food more. In addition, studies show that     10     eating habits, for example, taking three meals a day at the same time each day, are better for our health. It is also better to eat a modest amount of food each time, rather than to eat a lot in one meal, and then a little in the next.
