Interrogative Sentence

Interrogative sentences are the ones which ask a question. These are sentences that often are used while making conversation. Although it seems that they merely ask a question, an interrogative sentence is of four types-:

These are the questions that can be answered with either a yes or a no.
For example-:
Have you done your homework?
Are you ready?
These are the questions that provide you with two alternative answers.
For example-:
Should I call you or email you?
Do you want tea or coffee?
These are the questions that begin with a “wh” word. Answers to these questions cannot be given with a yes or a no. Neither can you give an alternative answer. The answer may be either a simple sentence or a complex explanation.
For Example-:
Where do you live?
What are your hobbies?
Tag questions are the ones that change a declarative sentence to an interrogative. They are called tag sentences because they are tagged at the end. For Example-:
You like basketball, don’t you?
You are coming to the party, aren’t you?
    1. Often it so happens that a question mark is put at the end of declarative sentence. This actually makes the sentence an interrogative sentence. For example-:
      India won the world cup?
      It’s raining?
      In such cases the last word of the sentence is said with a rising intonation.
    2. Often finding the subject of interrogative sentences is quite difficult. The best way to do it is write the answer of the question and you will find out its subject?
      For example-:
      Where is he going?
      He is going to the market.
      The answer talks about him (he) and hence he is the subject.
