What is a one-sentence summary of the following article?
Your teacher is not just standing up for their health; they are trying to educate you. Give them respect. Show them that they have your full attention, by looking them in the eye, and listening. Try your best to look alert. If you feel your eyes averting to something else in the room, catch yourself and focus back on your teacher. Your teacher should have your full attention at all times during class. Your eyes should not be drifting elsewhere. Most teachers tell you the subject of the class and the objective they are aiming for you to learn. If possible, write down this objective the minute you hear it. What is it that needs to be done today? What will you be learning about? How can you remain alert and focused during this time? Set goals for yourself, and remind yourself of the objective throughout class. This way, you know exactly what you have to do. . By taking accurate notes, you'll be able to "get into" the lesson. Recognize key points as your teacher speaks, and listen for key phrases such as "This is important," "This is the main idea," and "This will be on the test,", for example. This can alert you to listen more intently; you'll have something to do and focus on.  Objectives: If your teacher normally writes down the lesson's objective at the beginning of the class, keep it in your head and make sure you've achieved it by the end of the lesson. Don't try to finish up old notes or homework in class. Do that later, when you have free time or else you might miss key points. This is a wonderful way to become a more focused, successful student. When a teacher asks a question, offer to answer it. If she/he asks for an opinion, share your own. This shows that the teacher that you're listening intently during the class and that you know your stuff. This can also help you avoid those embarrassing moments, when you get called on and you happen to not be paying attention. Also, teachers will note to college officers that you are actively contributing in class. If you don't understand something, never be afraid to ask.

Chances are, someone else in the class has the same question and may have been afraid to ask. When you walk into that classroom, put a smile on your face and some confidence in your pocket. Be the best that you can be at all times, and show your true potential.
