Question

(1) Begin the sentences with "No sooner ..*
As soon as the thief escaped, the family informed the police,​

Answer 1

No sooner did the thief escape than the family informed the police.

Answer 2

After adding 'no sooner' to the following sentence, it becomes- ''No sooner had the thief escape than the family informed the police.''

• When we add 'no sooner' to this sentence, 'had' gets added after it and 'than' at the place of 'comma' as per rule.

• So, it has become negative sentence.
• The meaning remains same.
