Class 11 English Grammar Complete Guide with Examples

Introduction to Class 11 English Grammar#

Class 11 English under the NEB curriculum requires a solid command of English grammar. The syllabus is designed to build advanced language skills that prepare you for academic writing and professional communication down the line. Grammar questions carry about 30 to 40 percent of the total marks in the NEB Class 11 English exam, which means mastering grammar is one of the most efficient ways to secure a high score.

Tenses#

Tenses indicate the time of an action or state of being. English has 12 tenses formed by combining time (past, present, future) with aspect (simple, continuous, perfect, perfect continuous).

Here is an example of tense transformation. "She reads the newspaper every morning" in past simple becomes "She read the newspaper yesterday morning." "They are playing football" in present perfect becomes "They have played football." And "He had finished his homework before dinner" in future perfect becomes "He will have finished his homework before dinner." In NEB exams, the most commonly tested tense transformations are between Present Simple, Past Simple, Present Perfect, and Future Simple, so master these four first.

Active and Passive Voice#

Voice shows whether the subject performs the action or receives it. In active voice, the subject does the action: "The teacher explains the lesson." In passive voice, the object becomes the subject: "The lesson is explained by the teacher."

Voice Conversion Rules#

Tense	Active Structure	Passive Structure
Present Simple	S + V1 + O	O + is/am/are + V3 + by S
Present Continuous	S + is/am/are + Ving + O	O + is/am/are + being + V3 + by S
Present Perfect	S + have/has + V3 + O	O + have/has + been + V3 + by S
Past Simple	S + V2 + O	O + was/were + V3 + by S
Past Continuous	S + was/were + Ving + O	O + was/were + being + V3 + by S
Past Perfect	S + had + V3 + O	O + had + been + V3 + by S
Future Simple	S + will + V1 + O	O + will + be + V3 + by S
Modal Verbs	S + modal + V1 + O	O + modal + be + V3 + by S

Here are more examples. "The students are writing an essay" becomes "An essay is being written by the students." "She will complete the project" becomes "The project will be completed by her." Common mistakes in voice conversion include forgetting to change the verb to its past participle form, using the wrong form of the "be" verb, not switching the subject and object positions correctly, and omitting the agent when it is important to the meaning.

Reported Speech (Direct and Indirect Speech)#

To convert direct speech to indirect speech, follow these rules. Change the reporting verb: said to becomes told, says to becomes tells. Change the tense: present becomes past, past becomes past perfect. Change pronouns: first person changes according to the subject of the reporting verb. Change time and place references: now becomes then, here becomes there, today becomes that day. And remove quotation marks, using "that" for statements and "if" or "whether" for yes-no questions.

Here is a quick summary of the key rules:

1. Reporting Verb: Said to → told, says to → tells
2. Tense Change: Present → Past, Past → Past Perfect
3. Pronoun Change: First person changes according to the subject
4. Time/Place Changes: Now → then, here → there, today → that day
5. Remove Quotation Marks: Use that (for statements), if/whether (for yes/no questions)

Tense Changes in Reported Speech#

Direct Speech	Indirect Speech
Present Simple →	Past Simple
Present Continuous →	Past Continuous
Present Perfect →	Past Perfect
Past Simple →	Past Perfect
Past Continuous →	Past Perfect Continuous
Future Simple (will) →	Conditional (would)

For example: Direct: She said, "I am reading a book." Indirect: She said that she was reading a book. Direct: He said to me, "Did you finish your homework?" Indirect: He asked me if I had finished my homework. And an important exception: universal truths, habitual facts, and historical facts do not change tense. So "The teacher said that water boils at 100°C" remains in present tense.

Prepositions#

Prepositions show the relationship between a noun or pronoun and other words in a sentence. For time, use at for specific times, on for days and dates, in for months and years, by for deadlines, since for starting points, and for for duration. For place, use at for points, on for surfaces, in for enclosed spaces, and above, below, between, and beside for specific positions. For movement, use to for direction, into for entering, onto for moving to a surface, through for passage, and across for crossing.

Prepositions are best learned through context rather than memorizing lists. Read English newspapers and pay attention to how prepositions are actually used in sentences. Practice with gap-fill exercises to reinforce what you learn.

Sentence Transformation#

Sentence transformation is a key skill in NEB English exams. It means rewriting a sentence without changing its meaning. Common transformations include affirmative to negative, active to passive, direct to indirect, simple to complex, and simple to compound. For example: "He is honest" can become the negative "He is not dishonest." "A tired man sat down" can become the complex "A man who was tired sat down." And "Being tired, he sat down" can become the compound "He was tired, so he sat down."

Clauses#

A clause is a group of words containing a subject and a verb. There are two main types: independent clauses that can stand alone as complete sentences, and dependent clauses that cannot. An independent clause example is "She sings beautifully." A noun clause acts as a noun: "What she said surprised me." An adjective clause modifies a noun: "The book that I read was interesting." And an adverb clause modifies a verb: "She left because she was tired."
