enjoy 后面接 to do 还是 doing？stop to smoke 和 stop smoking 差在哪？动词接续形式是初中语法的必考拼图，完形和单选都爱出。这篇把三类清单列全，配口诀记忆。
只接 to do 的动词（想要打算类）
- want、would like、hope、wish：I want to drink some water.
- decide、plan、agree、refuse：They decided to stay at home.
- learn、promise、fail、afford：She learned to swim at seven.
- 记忆方向：这类动词都带「尚未发生的打算」色彩
只接 doing 的动词（进行享受类）
| 动词 | 含义 | 例句 |
|---|---|---|
| enjoy | 享受 | He enjoys reading books. |
| finish | 完成 | I finished doing my homework. |
| mind | 介意 | Would you mind opening the window? |
| keep | 保持、继续 | Keep trying and you will succeed. |
| practise / suggest / avoid | 练习、建议、避免 | She practises speaking English every day. |
口诀：喜欢享受勤练习，建议避免别介意（like、enjoy、practise、suggest、avoid、mind 都接 doing）。like、love、start、begin 两者皆可，意思差别不大。
辨析：stop to do vs stop doing
stop doing 表示停止手头正在做的事——He stopped smoking（他不抽了）；stop to do 表示停下来去做另一件事——He stopped to have a rest（停下来，目的是休息）。判断方法看 to do 是不是新的目标动作：是目标就选 stop to do。同族还有 remember 和 forget：remember to do 记得要去做（还没做），remember doing 记得做过（已发生）。考题给上下文时间状语，先判断动作做没做，再定形式。
