写好应用文应注意以下几点：
1）要注意各种应用文的书写格式。应用文都有自己的格式，这就要求平时牢记在心，以免犯错误。有的同学在写信时受中文思维影响，把写信时间写在信的右下角；还有的同学在写口头通知时在结尾注明通知时间、通知人或单位等，这种错误是高考中最忌讳的。
2）要熟练掌握应用文开头和结尾的一些习惯性写法。如：
    口头通知的开头语：Attention, please. / May I have your attention, please? / I have an announcement to make.
    结束语：Don’t forget the time and the address. / I’m sure you’ll have a lot of fun. / That’s all, thank you.
　  欢迎词的开头语：Welcome to our school. / Now let me tell you something about our city.
    结束语：I’m sure you’ll have a good trip. / I hope you’ll enjoy your stay here. That’s all. Thank you.
　  写信时的开头语：I am glad to hear from you. / I’m writing to tell you something about ... / How are you getting along with your studies?
    结束语：I’m looking forward to hearing from you soon. / Remember me to your parents. / Please give my best regards to ...等。
