　　If the teacher asks a question, you are expected to give an answer．If you do not understand the question, you should put up your hand and ask the teacher to repeat the question．If you do not know the answer, it is all right to tell the teacher that you do not know．Then he or she knows what you need to learn．

　　There is no excuse for not doing your homework．If you are absent(缺席)，you should call your teacher or someone who is in you class and ask for the assignment(作业)．It is your responsibility(责任)to find out what assignments you have missed．It is not the teacher's responsibility to remind you of missed assignments．

　　Be on time!It is considered(认为)rude to be late．Also, it disturbs 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 room．Then go to your seat and sit quietly．In the U．S．it is not necessary to knock before you enter the classroom．If you must leave during class, do so quietly．There is no need to ask the teacher's permission．Entering a teacher's office or any office with a closed door without knocking first is not acceptable．Knock first, then wait to be invited in．

　　Yellowstone is a huge park covering over 3, 400 square miles in Wyoming, Montana and Idaho．It can be reached by air to Cody and Jackson, 50 miles from the entrances．There is no train service nearby．Limited bus service is used from some of the towns near it．Once in the area, a car is almost a must．The park has 5 entrances, which are open from May to October．It is a good idea to plan a trip during the good weather, but you may expect big crowds and slow traffic．Parts of the park are open in the winter for snow sports．

　　Be sure to come prepared for different weathers at any time of the year．Take enough of your clothing so you will be prepared for unexpected changes in temperature．Take good walking shoes and thick socks, if you are going to do any hiking．You can also see the park on horseback．
