参考答案

    Dear_sir，
    We_all_feel_happy_to_have_you_as_our_new_English_teacher_and_we’re_glad_to_write_to_you_to_express_our_hope_about_your_class.Since it’s the first time for you to be our teacher，we would feel grateful if you speak slowly because many of us can’t quite follow you.Besides，when you explain important language points，would you please give us more examples and write some long and difficult sentences on the blackboard to make sure that all of us understand you？We also hope that you will repeat some difficult language points again and again so that we will grasp them completely.What’s more，although doing homework is a way to check if all of us can control the knowledge，we hope that there will be less homework.Last but not least，we hope to have more chances to stay with you，so please come to our classroom more often to become our teacher as well as our good friend.
    Thank_you_and_good_luck_to_you.
    Yours，
    Students
