什么是 “In Addition to”？
in addition to 是一个英语介词短语，意思是“除了……之外（还）”，用于引出额外的信息或事物。
基本结构
其后通常接名词、代词或动名词（即动词的 -ing 形式）：
- In addition to books, she bought a notebook.
- In addition to him, everyone passed the exam.
- In addition to reading, he enjoys writing.
常见错误
很多人误将 in addition to 当作连词使用，后面直接跟完整句子。这是不正确的。正确做法是使用动名词或名词结构。
❌ 错误：In addition to he plays piano...
✅ 正确：In addition to playing piano...
与 “Besides” 和 “Moreover” 的区别
Besides 也可表示“除……之外还有”，语气更口语化；Moreover 则用于正式写作中连接两个句子，强调递进关系。
- Besides English, she speaks French.
- The plan is risky. Moreover, it’s expensive.
实用例句
