Question

swimming is good exercise. (rewrite the sentence beginning with it)

Answer 1

Answer:

Swimming is the good exercise

Answer 2

'It is said that swimming is good exercise.'- is correct.

• The sentence in the question is an example of assertive sentence. It is a statement that is stating a fact. To begin the sentence with 'it' we have to change the sentence into reported form.
• Phrases like 'It is said', 'They say' or 'It is rumoured' are forms of reporting an assertive sentence.
• We usually use third person pronouns to begin such sentences as we are reporting a speaker.
