Overview
to + verb）或动名词（verb-ing）的动词时。forget 这个动词尤其是一个重要的例子，选择哪种形式会极大地改变其含义。这种区别不仅仅是风格问题，它反映了遗忘行为与被遗忘行为之间时间关系的根本差异。对于 B1 级别的学习者来说，理解这种区别是准确表达复杂思想、避免常见误解的关键一步。forget 以及许多其他动词，如 remember、try 和 stop，在这些动词中，语法选择传达了不同的语义信息。忽视这种区别可能导致严重的误解，因为‘未能做某事’的含义与‘不记得做过某事’的含义截然不同。forget to do 和 forget doing 的语法规则，提供一个全面的使用指南。你将学会何时使用每种形式、为何含义不同，以及如何在各种沟通情境中应用这些知识。理解这种区别能将你对英语的掌握从基本功能提升到细致入微的层面，使你能够更自信、更精确地表达自己的想法。forget + infinitive 和 forget + gerund 之间的关键区别完全取决于遗忘发生的时间相对于所描述的动作。这种时间上的区分是英语语法表达因果关系和记忆的核心，为理解意图和回忆提供了清晰的框架。掌握这个时间要素是解锁这些结构准确应用的关键。forget + to + verb 时，不定式表示一个有意图、计划或义务的动作，但由于遗忘发生在动作发生之前，所以这个动作从未被执行。这里的重点是遗漏——动作未完成。你可以把它想象成待办事项清单上一个未被打勾的任务。例如，如果你说 I forgot to lock the door（我忘了锁门），这意味着锁门这个动作本应发生，但你没有去做。门保持未锁状态。这种结构通常暗示着某种后果、错误或未履行的责任。She forgot to reply to the email（她忘了回复邮件）表示邮件未得到回复，因为她不记得去发送。forget + verb-ing 时，动名词指的是一个确实在过去发生过的动作，但你不再保留做这件事的记忆。遗忘发生在动作完成之后。这里的重点是回忆的丧失——动作是过去的现实，但那个特定事件的记忆已从你的意识中消失。想象一下日记中被遗忘的一页；事件发生了，但你无法再提取写下它的记忆。例如，如果你说 I forgot meeting him（我不记得见过他），这意味着你们确实见过面，但你没有关于这次相遇的记忆。对他来说，你是一个陌生人，即使他清晰地记得你们的谈话。He completely forgot saying that yesterday（他完全不记得昨天说过那些话）意味着那些话确实说出口了，但他完全不记得自己说过。Forget + to + verb: 动作是在将来（从遗忘发生的那个时间点来看），并且未完成。它关乎未能采取行动。其后果通常是未履行的义务或错失的机会。Forget + verb-ing: 动作是在过去（从遗忘发生的那个时间点来看），并且已完成。它关乎未能记住过去的某个行为。其后果通常是个人记忆中的一个空白，或者对自己无法回忆起的过去行为感到惊讶。I forgot to submit the report（我忘了提交报告），你就明白报告不见了，需要处理。如果他说 I forgot submitting the report（我不记得提交报告了），你可能会感到困惑，不知道他是否提交了但只是不记得了，还是他在试图否认。选择哪种说法传达了关于责任和记忆的截然不同的情况。这使得精确性变得至关重要，尤其是在职业环境中，问责制是关键。你信息的完整性取决于选择正确的语法形式来传达一个动作是缺失了，还是仅仅从记忆中缺失了。forget 的这两种不同结构的构成方式在各种时态中都是一致的，只需要正确地对 forget 进行时态变化，并使用后续动词的适当形式即可。理解这些模式可以让你可靠地应用这个规则，无论你想表达何种时间语境。掌握这些结构可以确保你的信息在语法上是正确的，并且在语义上是准确的。Forget + Infinitive (to + verb)Subject + forget/forgets + to + Base Verb | Intended action was not performed. | I often forget to bring my umbrella.（我经常忘记带伞。） | She forgot to lock the door.（她忘了锁门。） | He has forgotten to call his mother.（他忘了给他妈妈打电话。） | You mustn't forget to pay.（你一定不能忘了付钱。） |Subject + didn't/don't forget + to + Base Verb | Intended action was performed. (Negative) | Don't forget to send the email!（别忘了发邮件！） | I didn't forget to remind her.（我没忘了提醒她。） | She hasn't forgotten to submit it.（她没忘了提交它。） | You shouldn't forget to eat.（你不该忘了吃饭。） |forgot to confirm your appointment, so it was cancelled. （你忘了确认你的预约，所以被取消了。）Please don't forget to turn off the stove after cooking. （做饭后，请别忘了关掉炉子。）had forgotten to mention the new policy during the briefing, causing confusion. （经理在简报会上忘了提及新政策，引起了困惑。）Forget + Gerund (verb-ing)Subject + forget/forgets + Verb-ing | Past action was performed, but memory is lost. | I forget meeting famous people.（我不记得见过名人。） | He forgot saying that in the meeting.（他不记得在会议上说过那些话。） | She has forgotten taking that picture.（她不记得拍过那张照片。） | I can't forget seeing that film.（我忘不了看那部电影的经历。） |Subject + didn't/don't forget + Verb-ing | Past action was performed, and memory is retained. (Negative) | I don't forget learning new words.（我不忘记学习新单词。） | He didn't forget telling you.（他没忘记告诉过你。） | They haven't forgotten living there.（他们没忘记住在那里的经历。） | You shouldn't forget helping me.（你不该忘了你帮过我。） |I completely forgot asking you that question earlier today. My apologies. （我完全不记得今天早些时候问过你那个问题了。抱歉。）had forgotten visiting that ancient temple. （看着老照片，她意识到自己忘了去过那个古老寺庙的经历。）forget learning basic math facts they once knew well. （令人惊讶的是，有些人会忘记那些他们曾经熟练掌握的基本数学事实。）forget 的这两种形式都可以出现在各种时态和情态动词中。关键在于根据你想表达的关于记忆和动作的语境，始终如一地使用不定式来指代未完成的意图，使用动名词来指代对已完成的过去动作的记忆丧失。结构本身很简单；挑战在于根据语境选择语义上合适的词形。forget + infinitive 和 forget + gerund 的精确应用取决于你想要传达的关于记忆和动作的具体信息。选择正确的形式可以确保清晰度，避免沟通失误，这在个人和职业交往中尤其关键。理解每种用法的常见场景将巩固你对这一模式的掌握。Forget + to + verb (未完成的意图)I'm so sorry; I completely forgot to send you the updated project timeline. （非常抱歉；我完全忘了把更新的项目时间线发给你。） （时间线未发送。）Remember to turn off all the lights before you leave. Don't forget to lock the main door, too. （离开前记得关掉所有灯。也别忘了锁大门。） （这些动作必须完成。）She felt terrible because she forgot to attend her friend's graduation ceremony. （她感到非常糟糕，因为她忘了参加朋友的毕业典礼。） （她没有去参加典礼。）He forgot to pick up his prescription, so he had to go back to the pharmacy later. （他忘了去取处方，所以后来不得不又回到药店。） （处方未取。）The chef forgot to add salt to the soup, making it taste bland. （厨师忘了在汤里加盐，导致味道很淡。） （盐未添加。）I forgot to charge my phone last night, and now the battery is dead. （我昨晚忘了给手机充电，现在电池没电了。） （手机未充电。）Forget + verb-ing (对过去动作的记忆丧失)Did I really say that? I completely forgot saying it, honestly. （我真说过那话吗？说实话，我完全不记得说过。） （话已出口，但你不记得。）She looked at the old photographs and realized she had forgotten visiting that remote island during her childhood. （她看着老照片，意识到自己忘了童年时去过那个偏远岛屿的经历。） （这次访问确实发生了，但记忆已消失。）He told me we met at the conference, but I forgot meeting him. He seems familiar now. （他告诉我我们在会议上见过，但我忘了见过他。他现在看起来有点眼熟。） （这次会面发生过，但你记不清了。）I can't believe I forgot leaving the car keys on the kitchen counter instead of in my bag. （我真不敢相信我忘了把车钥匙留在厨房柜台而不是包里。） （钥匙确实被留在了那里，但你忘了这个动作。）forget to do 指向的是一个未来的失败或未完成的意图，而 forget doing 指向的是对一个已完成的过去动作的记忆缺失。理解这种时间上的差异是正确使用 forget 的关键。forget to do 和 forget doing 的混淆是一个非常常见的问题。这主要源于中文里没有与英语时态和动词形式相对应的语法结构来区分这两种情况。forget doing 用作“忘了去做某事”I forgot meeting him yesterday. (本意是“我昨天忘了去见他”，但这样说会让人以为“我不记得昨天见过他”。)forget + verb-ing，因为它看起来更像中文的“说”或“做”这样的动词形式，而忽略了英语中“to + verb”表示未完成的意图的特殊用法。I forgot to meet him yesterday. （表示你本应去见他，但因为忘了，所以没去。） 如果你想表达“我不记得昨天见过他”，那你的说法 I forgot meeting him yesterday. 才是正确的。forget + infinitive 中“未完成”的含义forget + verb-ing。forget + verb-ing 是一个更自然的“动词化”表达，而没有深究其“已完成但失忆”的语义。当他们想表达“忘了交作业”时，可能会说 I forgot submitting my homework.，这听起来像是“我不记得我交作业这件事了”，而不是“我忘了交作业，所以没交”。I forgot to submit my homework.，清晰地表明作业未被提交。Don't forget to call me（别忘了给我打电话）是一个指令，强调“必须打”。而 I don't forget calling him（我不忘记给他打电话）则表示“我记得我给他打过电话”。很多学习者可能会在需要强调“不要忘记去做某事”时，错误地使用 Don't forget calling me.，这在语法上不符合标准用法，且意思可能不明确。forget 后面接不定式或动名词的用法，与其他一些动词（如 remember, try, stop）的用法非常相似。这些动词在接不定式和动名词时，含义都会发生变化。理解这些对比有助于更全面地掌握这类动词的用法。to + verb) | Meaning with Gerund (verb-ing) | Chinese (Simplified) Equivalent (Approximate) |forget + to + verb | Failed to do something (action not performed) | Don't remember doing something (action was performed) | 忘了（去做），不记得（做过） |forget + verb-ing | (See above) | (See above) | (See above) |remember + to + verb | Remember to do something (an obligation or plan) | Remember doing something (recalling a past experience) | 记得（去做），记得（做过） |remember + verb-ing | (See above) | (See above) | (See above) |try + to + verb | Make an effort to do something; attempt | Test something to see if it works; experiment | 努力（去做），试一试（做某事看效果） |try + verb-ing | (See above) | (See above) | (See above) |stop + to + verb | Stop one activity in order to do another | Cease doing something; discontinue | 停下来（去做另一件事），停止（做某事） |stop + verb-ing | (See above) | (See above) | (See above) |forget vs remember:forget to do (忘了做) vs remember to do (记得去做)。两者都指未发生的动作，但前者是疏忽，后者是履行义务。forget doing (不记得做过) vs remember doing (记得做过)。两者都指已发生的动作，但前者是记忆缺失，后者是回忆起经历。I forgot to call him. (我忘了给他打电话，所以没打。) vs I remembered to call him. (我记得给他打电话，并且打了。)I forgot seeing him. (我不记得见过他。) vs I remembered seeing him. (我记得见过他。)try:try to do 强调的是努力去完成某事，但可能成功也可能失败。比如：I tried to open the heavy door, but I couldn't. (我努力想打开那扇沉重的门，但我做不到。)try doing 意味着尝试做某事，看看效果如何，通常是作为一种实验或选择。比如：If you can't sleep, try drinking some warm milk. (如果你睡不着，试试喝点热牛奶。) 这是一种建议，让你去尝试这个方法。stop:stop to do 表示“停下正在做的事情，以便去做另一件事”。这是一种目的。比如：He stopped to tie his shoelace. (他停下来系鞋带。——他本来在走路或做别的事，停下来是为了系鞋带。)stop doing 表示“停止做某事”。这是一种终止。比如：He stopped smoking. (他戒烟了。——他不再抽烟了。)forget to do 和 forget doing 在中文里有什么最接近的说法？forget to do 最接近的中文是“忘了（去做某事）”，强调的是动作未完成。forget doing 最接近的中文是“不记得（做过某事）”，强调的是对过去事件的记忆缺失。虽然中文的“忘了”有时可以涵盖这两种情况，但英语的区分非常明确。forget to do 还是 forget doing？Don't forget to + verb，例如 Don't forget to send the red envelope!（别忘了发红包！）。如果你想表达“我忘了做某事”，就用 I forgot to + verb，例如 I forgot to transfer the money.（我忘了转账。） 如果你想表达“我不记得做过某事”，比如“我不记得我什么时候加过你”，那就是 I forgot adding you.forget 后面接不定式和动名词，在表示“忘记”这个概念时，哪种更常用？forget to do（忘了去做某事）可能比 forget doing（不记得做过某事）更常用一些，因为它涉及到我们日常生活中需要完成的各种任务和义务。例如，我们经常会“忘了交作业”、“忘了带钥匙”、“忘了打电话”。而“不记得做过某事”通常发生在回忆往事或被别人提醒时，相对来说场景会少一些。forget 后面接不定式和动名词，在时态上有什么特别的限制吗？forget 后面接不定式或动名词，其本身可以根据句子的需要变成各种时态，比如 forget (现在时), forgot (过去时), has forgotten (现在完成时), will forget (将来时) 等等。关键在于，无论 forget 变成什么时态，它后面不定式和动名词的含义区分（未完成的意图 vs. 已完成但失忆）是保持不变的。例如：I will forget to buy milk tomorrow. (我明天会忘了买牛奶。) 和 I will forget buying milk. (我（将来）会不记得我买过牛奶这件事。) 这种时态的灵活性使得我们可以表达更复杂的语境。Conjugating 'Forget' with Complements

Meanings

文化笔记
British speakers often use 'forgotten' as the past participle, but in casual speech, 'forgot' is sometimes heard. 'I've forgot to do it' is common in some dialects but considered non-standard.
American English strictly uses 'forgotten' as the past participle. 'I've forgotten to...' is the standard way to express a recent missed task.
In corporate settings, saying 'I forgot to...' is seen as taking responsibility. Saying 'I forgot doing...' can sound like you are disorganized or have a poor memory for your own actions.
The word 'forget' comes from Old English 'forgytan', meaning 'to lose grip on' or 'to let go'.
对话开场白
What is one thing you always forget to do in the morning?

常见问题 (8)
Yes, 'forget about' is usually followed by a noun or a gerund. 'I forgot about the meeting' or 'I forgot about calling him.' It often means you stopped thinking about it.
It is less common than 'forgot to'. Most people use it with 'never' for big memories. In other cases, they might say 'I don't remember doing that' instead.
'Forgot' is for a specific time in the past. 'Have forgotten' is used when the forgetting still affects the present (e.g., 'I've forgotten my password').
This is very rare and usually grammatically incorrect. Stick to 'I forgot doing' for past actions.
Yes! 'Remember to do' is for tasks, and 'Remember doing' is for memories. They are perfect mirrors of each other.
For tasks: 'I didn't forget to...'. For memories: 'I'll never forget...ing'.
'Forgot' is the past tense. 'Forgotten' is the past participle used with 'have' or in the passive voice.
This is common in casual speech, but technically you should use 'left' when you mention a place. 'I left my keys at home' is better.
