动名词与不定式 · PET / B1
天天向上 · 原创语法学习讲义
根据前面的动词、介词和句子目的选择 -ing 或 to do，并理解常见结构带来的意思差别。
常见 -ing 搭配
enjoy、avoid、finish、mind、suggest 等后面常接 -ing；-ing 也可作主语。
Learning a language takes regular practice.
学习语言需要经常练习。
suggest doing 正确；不要直接写 suggest to do。
常见 to do 搭配
decide、hope、plan、offer、agree 等后面常接不定式；want / ask / tell 可接宾语 + to do。
The teacher asked us to bring a notebook.
老师让我们带一本笔记本。
ask us to bring 不能漏 us；否定指令可写 told us not to run。
介词与目的
介词后通常接名词或 -ing；单独 to do 可表达目的。
We went to the library to find information about recycling.
我们去图书馆是为了查找回收相关资料。
look forward to 中 to 是介词，所以是 look forward to meeting you。
比较常见意思变化
stop doing / stop to do 区分停止动作与停下去做；remember to do 提醒要做，remember doing 回忆做过。
Remember to lock the door. I remember locking it this morning.
记得锁门。我记得今天早上锁过门。
有些动词两种形式都可用，如 like / love；不要把自然变体一律当成错误。
