Question

Transform sentences with 'as soon as' to sentences with 'no sooner than'.
As soon as I woke up, I brushed my teeth.

• A. No sooner did I wake up than I had brushed my teeth.
• B. No sooner had I woken up than I brushed my teeth.
• C. No sooner I woke up than I brushed my teeth.
• D. No sooner did I wake up than I brush my teeth.

Answer 1

Answer: (B)

No sooner had I woken up than I brushed my teeth.

'No sooner..than' is used to suggest that one action takes place immediately after another action. When 'no sooner..than' is used at the beginning of the sentences then auxiliary verb goes before the subject. No sooner always introduces the event that occurred first.

The given sentence can be transformed using no sooner..than by beginning the sentence with 'no sooner'' followed by 'than'.

Thus, option B is the correct answer as 'auxiliary verb - had' is before the subject 'I'. Options A, C, and D are grammatically wrong.
