写好英语作文合同需要注意以下几点：

标题

标题应明确注明“合同”两字，避免使用模糊的标题如“建议书”。

用词

使用正式和法律上的用词，避免口语化表达。例如，使用“assist”代替“help”，使用“partake in”代替“take part in”。

句子结构

尽量使用短句子，因为短句子比长句子更容易理解。

使用主动语态，避免被动语态，使句子更简洁明了。

明确性

避免使用可能产生歧义的语言，如“双周”应写为“两周”或“每隔一周”。

清晰定义合同中的术语和别称，避免模糊不清的表达。

正式性

合同应具有法律约束力，因此用词和表达都应保持正式和严谨。

双方信息

在合同开头明确双方的名称和身份信息，包括个人姓名、公司名称、地址等。

签约时间

在合同开头留出空格，注明签约时间，便于后续查找和参考。

引述语

在合同主体前加入引述语（如“鉴于”条款），简要说明合同的主要内容和目的，避免后续争议。

其他注意事项

避免使用“出租人”和“承租人”等容易混淆的术语，建议使用“房东”和“租户”。

确保合同内容真实准确，避免虚假陈述。
