动名词与不定式

动词后面该接 to do 还是 doing？这是 PET 完形填空和写作的高频考点。

一、只接动名词（doing）的动词

背这句口诀：「建议、避免、想象、完成，禁止、推迟、介意、享受」

动词	例
enjoy 享受	I enjoy swimming.
finish 完成	Have you finished eating?
mind 介意	Do you mind waiting?
avoid 避免	Avoid eating too much sugar.
suggest 建议	He suggested going by train.
practise 练习	She practises playing the piano.
keep 一直	Keep trying!
imagine 想象	Imagine living on Mars.
miss 错过	I missed seeing the film.
give up 放弃	He gave up smoking.

二、只接不定式（to do）的动词

动词	例
want 想要	I want to go.
hope 希望	I hope to see you.
decide 决定	We decided to leave.
plan 计划	They plan to visit us.
agree 同意	She agreed to help.
promise 承诺	He promised to come.
learn 学	I'm learning to drive.
offer 主动提出	He offered to pay.
refuse 拒绝	She refused to answer.
manage 设法做到	He managed to finish it.
would like 想要	I'd like to try.

三、两个都行，但意思不同（考点！）

动词	+ to do	+ doing
remember	记得要去做（还没做）	记得做过（已经做了）
	Remember to lock the door.（提醒）	I remember locking it.（记得锁过）
forget	忘记要做	忘记做过
	I forgot to call him.（没打成）	I'll never forget meeting her.（难忘那次见面）
stop	停下来去做另一件事	停止正在做的事
	He stopped to smoke.（停下来抽烟）	He stopped smoking.（戒烟了）
try	努力去做	试着做做看
	I tried to open it.（努力想打开）	Try turning it left.（试试往左转）

stop 那一组最常考：stop to do 是「停下来去做」，stop doing 是「不再做」。

四、介词后面一律用 doing

• I'm interested in learning Spanish.
• He's good at cooking.
• Thank you for helping me.
• Instead of going out, we stayed in.
• look forward to seeing you（这个 to 是介词！）
• be used to doing 习惯于（≠ used to do 过去常常）

两个 to 的区别是经典陷阱：

• I used to play football.（过去常踢，现在不踢了——to 是不定式）
• I am used to playing football.（习惯了踢球——to 是介词）

五、动名词作主语

Learning a language takes time.（动名词作主语，谓语用单数）
Swimming is good exercise.

这是 PET 开放填空的常考点：Learning languages is not easy（不是 are）。
