Sentences Exercises For Class 8 With Answers

Kinds of Sentences
Sentences are of four kinds:

  • Those which make statements or assertions; as,
    Humpty Dumpty sat on a wall.
  • Those which ask questions; as,
    Where do you live?
  •  Those which express commands, requests, or entreaties; as,
    Be quiet.
    Have mercy upon us.
  • Those which express strong feelings; as,
    How cold the night is!
    What a shame!

A sentence that makes a statement or assertion is called a Declarative or Assertive sentence.
A sentence that asks a question is called an Interrogative sentence.
A sentence that expresses a command or an entreaty is called an Imperative sentence.
A sentence that expresses strong feeling is called an Exclamatory sentence.

Assertive Sentence

These sentences merely assert an incident or a fact.
e.g. The sun is a big star. (Affirmative)
The Taj is a beautiful monument. (Affirmative)
He is not in Delhi. (Negative)
It does not glow at night. (Negative)
Sentences that affirm one or the other fact are called affirmative sentences. First two sentences listed above are affirmative ones.
Sentences that negate a fact are called negative sentences. The last two sentences listed above are negative sentences.

Interrogative Sentences :

These sentences simply ask questions.
Examples are:

  • Where are you?
  • When is your flight?
  • Have you finished your work?
  • Was your paper tough?

Note: Put a question mark (?) at the end of a questions.

Questions are of two types:

  1. Those begin with helping (auxiliary) verbs (be, is, are, am, was, were, has, have, had, shall, will, should, would, can, could, may, might, etc.) Examples:
    Have you met her?
    Was your examination easy?
  2. Those begin with ‘Wh’ question words (why, where, when, how, whose, whom etc.) are followed by helping words.
    Who is this lady?
    Why are you late?

Imperative Sentences
These sentences are used to order, advise, command or ask for some favour, Examples are:

  • Come here. (Order)
  • Please give me something to eat. (Request)
  • Listen to her. (order/advice)
  • Do not smoke here. (prohibition)


  • Begin an imperative sentence with a verb.
  • Do not use a subject. It is always You’ and is not mentioned.
  • Imperative sentences end with a full stop.

Exclamatory Sentences
These sentences express sudden feelings and emotions of the speaker.

Examples are:

  • Hush! the baby is asleep.
  • Bravo! our school team won the finals. (Joy)
  • Alas! I’ve lost my job. (Sorrow)
  • How pretty the picture is! (Surprise)
  • What a fool I am!

Simple, compound and complex sentences

Simple sentences contain one clause:

  • The girl is learning how to drive.
    Complex sentences contain more than one clause.
  • The girl who is learning how to drive is still twelve years old.
  • She faced the whole trouble with courage and managed to solve the problem all by herself.

A Simple Sentence
A simple sentence is one which has only one subject and one predicate. [Or] A simple sentence is one which has only one finite verb.

Sentence 2 consists of two parts:

  • The moon was bright.
  • We could see our way;

These two parts are joined by the Co-ordinating conjunction and. Each part contains a subject and a predicate of its own. Each part is what we call a clause.

We further Notice that each clause makes good sense by itself, and hence could stand by itself as a separate sentence. Each clause is therefore independent of the other or of the same order or rank, and is a called a principal or main clause.

For example

  • You can’t surprise a man with a dog.

A Complex Sentence
A complex sentence consists of one Main clause and more subordinate clauses.

Sentence 5 consists of the three clauses:

  • The people said. (main clause)
  • As the boxers advanced into the ring. (subordinate adverb clause)
  • They would not allow them to fight. (subordinate noun clause)

Such a sentence is also called a complex sentence.

For example:

  • Diplomacy is the art of saying “nice doggie” until you can find a rock. (Will Rogers, 1879 – 1935)
  • When you’re on the internet, nobody knows you’re a dog. (Peter Steiner)

A Compound Sentence
A sentence, such as the second, which is made up of Principal or Main Clause, is called a compound sentence. Sentence 3 consists of three clauses of the same order or rank. In other words, sentence 3 consists of three principal or main clauses, viz:

  • Night came on.
  • Rain fell heavily.
  • We all got very wet.

Such a sentence is also called a compound sentence.
A compound sentence is one made up of two or more principal or Main Clauses.
