Overview

Learning when to use a gerund (the -ing form of a verb used as a noun) or an infinitive (the 'to + verb' form) is a key step towards sounding more natural and confident in English. This introduction to gerunds and infinitives is perfect for B1 English grammar learners ready to refine their communication skills. Moving beyond basic sentence structures, understanding these forms allows you to express preferences, plans, and actions with much greater fluency.
Imagine being able to confidently say
I enjoy reading
instead of
I enjoy to read,
or making a polite request like "I'd like to order a coffee" without hesitation. This chapter will unlock those possibilities. You'll learn how to use -ing words as subjects, which verbs demand a gerund or an infinitive, and even discover verbs that are happy with either!
Mastering these patterns will significantly smooth out your English, making your conversations flow more effortlessly and professionally.

How This Grammar Works

At the heart of this grammar chapter is understanding how verbs can act differently in a sentence. Sometimes, an action itself becomes the subject of your sentence, like a noun. This is where the gerund comes in.
For example,
Swimming is great exercise
– here, 'swimming' is the subject of the sentence, not an action being performed by someone. It’s an action turned into a concept.
Next, certain English verbs are followed by a gerund. These verbs often express feelings, preferences, or activities. Think of verbs like enjoy, finish, or avoid.
You'll always use the -ing form directly after them:
I enjoy learning new things,
or
He finished working late.
Trying to use an infinitive here would sound unnatural.
On the other hand, many English verbs are followed by an infinitive. These verbs frequently convey plans, desires, intentions, or necessity. Common examples include want, need, decide, and plan.
For instance,
She wants to travel next year,
or
We need to leave soon.
Here, the infinitive 'to travel' or 'to leave' clearly states the purpose or goal.
Some verbs are flexible! With verbs with gerund or infinitive where there's no meaning change, you can choose either. Verbs like start, begin, continue, and like fall into this category.
You can say,
I like reading books
or
I like to read books,
and both are perfectly correct and mean the same thing. This flexibility can make them seem less daunting.
Finally, for making polite requests, especially in formal or semi-formal situations, we use the specific structure 'would like' + infinitive. This is a crucial phrase for politeness and professionalism. Instead of
I want a drink,
you would politely say,
I would like to have a drink,
or
We would like to reserve a table.
This small change makes a big difference in how your request is perceived.

Common Mistakes

Learning gerunds and infinitives can be tricky, but recognizing common errors will help you avoid them.
  1. 1✗ I enjoy to read books.
✓ I enjoy reading books.
*Explanation*: The verb 'enjoy' is always followed by a gerund (-ing form).
  1. 1✗ He wants go to the park.
✓ He wants to go to the park.
*Explanation*: Verbs like 'want' are followed by the infinitive, which always includes 'to'. Don't forget the 'to'!
  1. 1✗ We would like ordering a dessert.
✓ We would like to order a dessert.
*Explanation*: For polite requests with 'would like', you must use the infinitive form ('to' + verb).

Quick FAQ

Q

What's the main difference between a gerund and an infinitive?

A gerund (verb + -ing) acts like a noun, often representing an activity or concept (e.g.,

Running is healthy
). An infinitive ('to' + verb) often expresses purpose, intention, or a future action (e.g.,
I want to learn
).

Q

How can I remember which verbs take a gerund or an infinitive?

The best way is through practice and exposure. Start by learning the most common verbs that follow each pattern (like enjoy + gerund, want + infinitive). Over time, you'll start to recognize the patterns naturally. Pay attention when you read or listen to English.

Q

Are there any verbs that can take both gerunds and infinitives?

Yes! For verbs like start, begin, continue, and like, you can use either form, and the meaning typically doesn't change. For example,

It started raining
and
It started to rain
both mean the same thing.

Cultural Context

Using gerunds and infinitives correctly is not just about grammar rules; it's about sounding truly fluent and polite. Native English speakers naturally choose these forms, and mastering them helps you integrate more smoothly into conversations. Phrases like
would like to
are indispensable for showing respect in requests, making your English not just correct, but also culturally appropriate and genuinely communicative.

The 'It' Test

If you can replace the first word(s) of your sentence with 'It' and the sentence still makes sense, you have a gerund subject.

The Preposition Rule

If you see a preposition (in, at, of, for, about, with), the next verb MUST be a gerund. No exceptions!

The 'Future' Hint

If the second action hasn't happened yet (it's a plan or desire), you probably need 'to'.

常见错误

The verb 'enjoy' must be followed by a gerund, not an infinitive. It's a common trap!

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

Gerund subjects always take a singular verb. Remember to treat the action as one thing.

Wrong: Swimming are fun.
正确: Swimming is fun.

The verb 'want' requires an infinitive. It never takes an -ing form.

Wrong: I want going home.
正确: I want to go home.

常见问题 (6)

Yes, but it sounds very formal or poetic. In daily life, always use '-ing'.
Because the subject is the *act* of eating (one thing), not the apples themselves.
It depends on the main verb. Some verbs like enjoy just naturally take the gerund because it treats the action as a noun/concept.
Yes, like is one of the few verbs that can take both with almost no change in meaning.
No, in English we say I want you to go. We don't use 'that' after 'want'.
Only if it's a very casual email to a close friend. In business or formal writing, always use want to.
