Gerunds and Tenses are two of the most important grammar topics in the English sections of NDA, CDS, and AFCAT examinations. Questions based on these concepts frequently appear in Spotting Errors, Sentence Improvement, Fill in the Blanks, Cloze Test, Completion of Sentences, Active-Passive Voice, Direct-Indirect Speech, and other grammar-based sections. A strong command of these topics enables candidates to identify grammatical mistakes, understand sentence structure, and choose the correct answers with confidence.
In the English Live Class conducted for NDA, CDS & AFCAT 2 2026 aspirants, detailed discussion was held on the rules governing Gerunds and Tenses, along with extensive practice of exam-oriented multiple-choice questions. The session focused on helping candidates understand not only the theoretical concepts but also their practical application in objective-type questions commonly asked in defence examinations.
Understanding Gerunds
A Gerund is the -ing form of a verb used as a noun. Although it originates from a verb, it functions grammatically as a noun within a sentence.
Examples:
- Reading improves vocabulary.
- Swimming is an excellent exercise.
- He enjoys playing football.
In these examples, the words reading, swimming, and playing function as nouns rather than verbs.
Gerunds are commonly tested in defence examinations because candidates often confuse them with infinitives and participles.
Important Rules of Gerunds Discussed in the Live Class
Rule 1: Certain Verbs Are Followed by Gerunds
Some verbs are always followed by a gerund rather than an infinitive.
Examples:
- enjoy
- avoid
- admit
- appreciate
- consider
- suggest
- finish
Correct:
- He enjoys reading books.
- They avoided making mistakes.
Incorrect:
- He enjoys to read books.
- They avoided to make mistakes.
Such questions frequently appear in Sentence Improvement and Spotting Errors.
Rule 2: Gerunds after Prepositions
Whenever a verb follows a preposition, it generally takes the gerund form.
Correct:
- She is interested in learning English.
- He succeeded in passing the examination.
Incorrect:
- She is interested in learn English.
- He succeeded in pass the examination.
Questions based on this rule are common in Fill in the Blanks and Error Detection.
Rule 3: Gerunds as Subjects
A gerund can function as the subject of a sentence.
Examples:
- Reading develops knowledge.
- Travelling broadens one’s perspective.
Candidates must recognise that the gerund is functioning as a noun rather than an action verb.
Rule 4: Gerunds after Certain Expressions
Some expressions are commonly followed by gerunds.
Examples:
- cannot help
- look forward to
- be accustomed to
- be used to
Correct:
- I look forward to meeting you.

Incorrect:
- I look forward to meet you.

Understanding Tenses
A Tense indicates the time of an action or event. It shows whether an action occurs in the present, past, or future and whether the action is complete, continuous, or ongoing.

Importance in Direct and Indirect Speech
Reported speech often requires tense changes.
Example:
Direct:
He said, “I am preparing for the examination.”
Indirect:
He said that he was preparing for the examination.
Candidates must understand tense conversion rules to solve such questions correctly.
Importance in Active and Passive Voice
