It looks like you've uploaded a page from an English grammar textbook, specifically
Chapter 43, titled *"Gerunds, Infinitives, and Participles"*, with a focus on
Section 43a: How can I use gerunds and infinitives as subjects?
However, there is
no specific task or question visible in the image you provided. The text explains:
- What
gerunds and
infinitives are.
- How they function as
subjects in sentences.
- A key rule: When a gerund or infinitive is used alone as a subject, it is
singular and requires a
singular verb.
- An example:
- *Choosing the right health club is important.* (gerund as subject)
- *To choose the right health club is important.* (infinitive as subject)

✔ If your task was to:
Explain how gerunds and infinitives can be used as subjects, here’s a clear explanation based on the text:
---
🔹 Gerunds and Infinitives as Subjects
Both
gerunds (verb + *-ing*) and
infinitives (*to* + base verb) can act as
subjects of a sentence.
#### 1.
Gerunds as Subjects
A gerund is a verb form ending in *-ing* that functions as a noun.
✔ Example:
>
Swimming is good exercise.
>
Eating vegetables helps keep you healthy.
🔹 In these sentences, "Swimming" and "Eating vegetables" are
gerund phrases acting as the
subject of the sentence.
#### 2.
Infinitives as Subjects
An infinitive is the base form of a verb preceded by *to*.
✔ Example:
>
To learn a new language takes time.
>
To succeed in life requires effort.
🔹 Here, "To learn" and "To succeed" are
infinitive phrases serving as the
subject.

🚨 Important Rule:
When a gerund or infinitive is used
alone as a subject, it is
singular, so the verb must also be singular.
✘ Incorrect:
> Swimming are good exercise.
✔ Correct:
> Swimming
is good exercise.
Similarly:
> To study
is necessary.

💡 Tip:
You can often switch between gerunds and infinitives when they're used as subjects, and both may be acceptable, though one might sound more natural depending on context.
Example:
- *Reading books is enjoyable.*
- *To read books is enjoyable.*
Both are correct, but the gerund version is slightly more common in everyday speech.

✔ Summary:
| Form | Example | Subject Type |
|--------------|--------------------------------|--------------------|
| Gerund |
Swimming is fun. | Verb + *-ing* |
| Infinitive |
To swim is fun. | *to* + base verb |
👉 Both are
singular when used as subjects → use
singular verbs.
