If you are studying at school, do be a polite and clever student! There is no excuse for not doing your assignments. If you can't come to school, you should call your teacher or your classmate ask about homework. It is your responsibility to find out what homework you have missed. It is not the teacher's job to remind you of the missed assignments.

    You must not be absent on a test day. If you are seriously ill, call and let the teacher know you will not be there for the test. If your teacher allows a make-up test, you should take the test, again within one or two days after you return to class. Serious illness is the only reason for missing a test.

    Be on time! It is impolite to be late. Also, it bothers other students. If you must come in late, be sure to do it quietly. Have your books and papers out of your bag before you come into the classroom. Then go to your seat and sit down quietly. In the USA, it is not necessary to knock before you enter the classroom. Most teachers will give you a low grade if you are often late.

    In America, you should call your teacher by his or her last name instead of “teacher”. Also you should use Mr, Miss, Ms or Mrs before the last name (such as Mrs Smith or Mr Jones). The teacher will tell you the title that he or she likes. It is impolite in the USA to eat, drink or chew gum during class. Don't do these until the break. Also, removing your shoes in the classroom is not polite.

    Whenever the sun dropped and the blue sky came up, my father and I used to climb the mountain near my house. Walking together, my father and I used to have a lot of conversations through which I learned lessons from his experiences. He always told me, “You should have goals like climbing the mountain. ” without the mountain-climbing that we both enjoyed, we couldn't have enough time to spend together because my father was very busy. I really got a lot from mountain-climbing. It gave me time to talk with my father and to be in deep thought as well as develop my patience.

    Once we climbed a very high mountain. It was so challenging for me because I was only ten years old. During the first few hours of climbing, I enjoyed the flowers and trees, and the birds'singing, but as time passed, I got a pain in both of my legs. I wanted to quit climbing. In fact, I hated it at that mountain, but my father said to me, “You can always see a beautiful sky at the top of the mountain, but you can't see it before you reach the top. Only there at the top can you see all of the nice things, just like in life. ”

    At that time, I was too young to understand his words. But later after that, I got new hope and confidence. I found myself standing at the top of the sky, which was as clear as crystal.
