O que você vai aprender

Você já se sentiu travado na hora de escolher entre 'to go' ou 'going'? No nível B2, a verdadeira fluência está nos detalhes, e este capítulo é o seu passaporte para soar muito mais natural. Vamos mergulhar nos padrões verbais que dão ritmo ao inglês, desvendando quando usar o infinitivo (como em 'manage to') e quando o gerúndio é a única opção correta (como em 'avoid doing'). O segredo aqui é a sutileza: você aprenderá como uma simples escolha muda todo o sentido da frase — essencial para evitar mal-entendidos em situações reais, como a diferença crucial entre 'parar de fumar' e 'parar para fumar'. Imagine-se em uma reunião de trabalho ou contando uma história vibrante para amigos; você usará verbos de percepção para descrever cenas com riqueza de detalhes e dominará os 'phrasal verbs' de três partes, como 'look forward to', que são o coração do inglês cotidiano. Além disso, vamos colocar um fim na dúvida entre 'do' e 'make' e explorar formas avançadas como 'to have done' e 'having done'. Ao terminar, você não estará apenas montando frases, mas articulando pensamentos complexos e precisos, descrevendo intenções e ações com a confiança de quem realmente domina o idioma. Vamos elevar o nível do seu inglês?

Overview

Moving beyond basic communication to express yourself with true nuance and confidence is a hallmark of B2 English grammar. This chapter is your key to unlocking that next level of fluency by mastering verb patterns and actions. It's about more than just getting your message across; it's about sounding natural, precise, and sophisticated, allowing you to interact with native speakers effortlessly.
We'll dive deep into those often-confusing choices between a 'to-infinitive' (like 'to do') and a 'gerund' (like 'doing'), showing you how these seemingly small decisions drastically impact meaning and flow.
Understanding these patterns isn't just about avoiding grammatical errors; it's about gaining an intuitive grasp of how English speakers structure their thoughts. You'll learn to confidently use verbs that *only* take a 'to-infinitive' or *only* a 'gerund', navigate those tricky situations where the choice changes the entire meaning of your sentence, and master essential phrasal verbs and verbs of perception. By the end of this guide, you'll be able to articulate your ideas with greater accuracy and sound even more like a native speaker, ensuring your English truly shines.

How This Grammar Works

At the heart of mastering verb patterns and actions lies the understanding that certain verbs have a rule about what follows them. Think of it like this: some verbs are followed by a 'to-infinitive' (e.g., 'decide to go', 'promise to call', 'manage to finish'). These verbs act as gates, only allowing the 'to' form to pass.
For example, you would say
I decided to study abroad,
not
I decided studying abroad.
These are generally about future intentions or commitments.
On the other hand, many verbs belong to what we call the '-ing Club', meaning they are *only* followed by a gerund (the -ing form of a verb). Mastering these makes your English sound incredibly natural. Imagine saying
I enjoy playing tennis
or
She avoids making mistakes.
Trying to use enjoy to play or avoid to make would immediately flag you as a non-native speaker.
These verbs often express feelings, continuous actions, or mental processes.
Things get really interesting when a verb can be followed by *either* a gerund *or* a 'to-infinitive', but the meaning changes entirely. Take 'remember':
I remember locking the door
refers to a past memory (you recall the *action* of locking), while
I remembered to lock the door
means you didn't forget to perform the *task* of locking it. This subtle distinction is crucial for clear communication.
Similarly, 'stop' can mean to cease an ongoing action (
He stopped talking
) or to pause one action in order to do another (
He stopped to talk
).
Our senses also have specific patterns. With verbs of perception like 'see,' 'hear,' 'watch,' we use a bare infinitive (verb without 'to') for a complete action (
I saw him leave the building
) and a gerund for an action in progress (
I saw him leaving the building
). Finally, to truly sound like a B2 speaker, you need to master adjectives + prepositions (like 'proud of', 'keen on', 'interested in') and three-part phrasal verbs (e.g., 'get on with', 'look forward to').
These are fixed expressions that add richness and authenticity to your vocabulary, and using them correctly demonstrates a deep understanding of natural English phrasing.

Common Mistakes

  1. 1
    I avoid to make mistakes when speaking English.
I avoid making mistakes when speaking English.
Explanation: The verb 'avoid' is always followed by a gerund (the -ing form).
  1. 1
    He stopped talking to buy a coffee.
He stopped to buy a coffee.
(or
He stopped talking because he wanted to buy a coffee.
)
Explanation: Stopped talking means he ceased the action of talking. Stopped to buy means he paused his journey/activity *in order* to buy a coffee. The infinitive shows purpose.
  1. 1
    I am looking forward seeing you next week.
I am looking forward to seeing you next week.
Explanation: Look forward to is a common three-part phrasal verb where 'to' is a preposition, not part of a to-infinitive. Therefore, it must be followed by a gerund.

Quick FAQ

Q

Why is it sometimes remember to do and sometimes remember doing?

Remember to do means you recall a necessary action you have to perform (e.g.,

I must remember to buy milk
). Remember doing means you have a memory of a past event or action (e.g.,
I remember buying that book last year
).

Q

How do I know if a verb takes a gerund or an infinitive?

There are patterns, but often it comes down to memorization and exposure. Many verbs related to feelings (enjoy, hate, like), avoiding, or continuing take gerunds. Verbs related to decisions, plans, or intentions often take infinitives. Keep a list and practice!

Q

Are three-part phrasal verbs common in everyday English?

Absolutely! They are incredibly common and essential for sounding natural. Phrases like get on with, look forward to, put up with, and run out of are used constantly in casual and even semi-formal conversation.

Q

What's the difference in meaning between

I saw him run
and
I saw him running
?

I saw him run
implies you saw the complete action from beginning to end.
I saw him running
suggests you witnessed part of the action while it was in progress, like a snapshot.

Cultural Context

Native English speakers seamlessly weave these verb patterns into their everyday speech, often without consciously thinking about the rules. The choice between gerunds and infinitives, especially when the meaning changes, is vital for precise communication and avoiding misunderstandings. Phrasal verbs are particularly prevalent in informal and semi-formal contexts, adding a layer of expressiveness and efficiency.
While regional differences exist in slang or specific idioms, the core verb patterns discussed here are standard across all major English-speaking regions and are crucial for achieving that authentic B2 sound.

Erros comuns

Enjoy is followed by a gerund, not an infinitive. It's a common error for many learners.

Wrong: I enjoy to read.
Correto: I enjoy reading.

In this phrasal verb, 'to' is a preposition, so it must be followed by a gerund.

Wrong: I look forward to hear from you.
Correto: I look forward to hearing from you.

Homework is a task, so we use 'do'. 'Make' is for creating something new.

Wrong: I made my homework.

Perguntas comuns (6)

A regra é que verbos como 'decide', 'promise' e 'manage' são seguidos por 'to' + a forma base do verbo seguinte, como em:
I decided to leave.
Eles costumam indicar intenções, ações futuras, propósitos ou o sucesso em completar uma tarefa:
I plan to study.
O gerúndio é a forma -ing do verbo quando ele funciona como um substantivo. Por exemplo, em I enjoy reading, a palavra 'reading' é o objeto direto do que você gosta.
É uma convenção da língua. Geralmente, esses verbos expressam a ação como uma atividade ou experiência contínua, em vez de um objetivo futuro: I finished working.
Pense no objetivo. Stop smoking significa que você abandonou o vício. Stop to smoke significa que você fez uma pausa no que estava fazendo para fumar:
I stopped to smoke a cigarette.
Não exatamente. Embora existam nuances sutis entre I like swimming (prazer geral) e
I like to swim
(hábito), o sentido principal de preferência não muda drasticamente como no 'stop'.
