三、书面表达。
假设你是李华，你的美国朋友 Mike 即将来中国交流学习，请你给他写一封邮件，介绍一些在中国需要注意的规则和礼仪，如交通规则、餐桌礼仪等。词数80左右（邮件的开头和结尾已给出，不计入总词数）。
Dear Mike,
I'm glad to hear that you're coming to China for exchange study. Here are some rules and manners you should know.





I hope you'll have a great time in China.
Best regards,
Li Hua

First, about traffic rules, you must remember all the cars and buses keep to the right in China. You mustn't cross the road when the traffic light is red. Second, for table manners, it's impolite to stick your chopsticks into the rice. You shouldn't start eating before the elders at the table do. Also, you can bring a small gift if you are invited to a Chinese home, that is very polite.

这是一篇介绍中国礼仪规则的应用文写作，写作要点如下：1. 内容需覆盖题干要求的交通规则、餐桌礼仪两大核心部分，可适当补充简单的日常社交小提示，符合给朋友写邮件的交流场景；2. 选用七年级已学的简单句式如you should/you mustn't等表达规则要求，避免超纲词汇，词数控制在80左右即可；3. 语气友好自然，符合日常邮件的表达风格。
