【答案】Dear John，
    I know that you will be invited to your Chinese classmate's home.If you do the following，I don't think you will feel uncomfortable.
    First，you should arrive a little earlier or on time.Being late is impolite.Second，it's also good to bring a gift such as some flowers or fruit.Third，you will probably use chopsticks to have dinner.Remember not to stick your chopsticks into your food.You aren't supposed to point at anyone with your chopsticks.Another thing is that you aren't expected to use your chopsticks to hit an empty bowl.You'd better say that the food is delicious while you are eating.Finally，after dinner，showing thanks is also necessary.And you are not supposed to stay long after dinner.
   Good luck and have a great time!
