Помогите составить вопросов 10 к тексту!!! очень надо..

When we first come to school, a teacher meets us. She says: "Good morning, children. I am your teacher. I am going to teach you how to write, to read and to count". No matter how many teachers we have after that, we remember our first teacher's name for the rest of our lives. During our school-years the teachers change, we really have a lot of them. When we leave school and go to a professional school or university, there are other teachers. Even when we are mature adults, with all our diplomas, if we want to learn something new, we go to a teacher. Teachers are with us all our life. We always remember what they say and how they act. Often they let us down. What should a teacher be like, so that his very existence isn't a complete disappointment for his students?
A teacher should be competent. He should study all the time. A teacher dies when he stops teaching himself.
A teacher should be tactful. He should never mock the students if they say or do something wrong. It's the easiest way to discourage them. Teaching them something new is like teaching a baby to walk. It requires infinite patience. If you are impatient, you break the baby's leg, and this baby will never walk.
Of course, a teacher shouldn't smoke or overindulge in drinking. It is also important how the teacher looks. I would suggest that all teachers do their exercises every day before they go to work. When a clumsy, floppy and gloomy creature enters the classroom and teaches you what is the best way of living and what you should do in life, would you believe him? I wouldn't.
When a teacher feels that his students irritate him and he snaps at them; when he notices that he cannot answer their questions on the subject; when the expression of his face is always angry and unfriendly - he should change his job immediately and keep away from school. ! Do teachers always do what they should?
