Dear Peter,
I'm glad to receive your email. You asked about how I use smart tools to learn English and I'd like to share my favourite one with you.
This app helps me practise my spoken English a lot. There are many short videos from cartoons and movies. I can dub the characters' lines, and the app will give me feedback on my pronunciation. It also creates vocabulary lists based on the videos to help me remember new words.
Before using it, my pronunciation was not good. But now, my English teacher often praises me for my clear speaking, and my English score has improved too! Do you use any smart tools for studies? Tell me about them!
Yours,
Li Hua

【分析】本题为英语应用文写作题，要求以李华的身份给Peter回信，分享自己使用智能工具学习英语的经历。解题思路：1. 遵循英文书信格式，确定开头称呼、正文主体、结尾署名；2. 围绕“用智能工具学英语”的主题，选择具体工具，说明其核心功能；3. 补充使用前后的变化，体现工具的效果；4. 结尾询问对方的学习工具，符合书信的互动性要求。
【解析】按照英文书信规范书写：开头称呼Dear Peter，说明收到邮件并点明分享学英语的智能工具；正文介绍工具的功能，如APP提供影视短视频，可配音并获发音反馈，生成词汇表；接着写使用前后的变化，如发音提升、获老师表扬、成绩进步；最后询问对方的学习工具，完成书信。
