Sentence. In addition, + sentence; In addition to + noun/-ing, + clause; clause + in addition to + noun
- Public libraries lend books for free. In addition, many of them run language clubs and computer courses.
- In addition to lowering costs, online meetings save the time people spend travelling.

修改原因
修改前In addition to work full-time, she is studying for a master's degree.
修改后In addition to working full-time, she is studying for a master's degree.
In addition to 后的动词要用 -ing，因为这里的 to 是介词，而不是不定式的一部分，可以对照 in addition to the salary。因此 in addition to work 改成 in addition to working。Look forward to 也有类似结构：look forward to meeting you。
In addition 只是增加一个论点；moreover 往往强调新论点更有分量。日常交谈中，两者都偏书面，常换成 also 或 plus：The flat is cheap, plus it's near the metro。考官经常见到 In addition，因此作文中可以根据语境与 also、what is more、not only… but also 等结构交替使用。
动手练习
Our hotel has an outdoor pool. ___ the pool, guests can use a sauna and a small gym for free.
查看答案
In addition to — 空格后直接跟名词 the pool，需要 In addition to，表示除了泳池之外。In addition 不带 to 时应作为连接表达引出新的陈述，不能像这里这样直接接名词。
描述一份让你感兴趣的工作或一门课程。以 In addition to 加 -ing 开头，在这部分写一个优点，再在主句中补充另一个优点。
In addition to offering a good salary, the company lets new employees work from home two days a week.
