English Grammar - Modals: 87 MCQs with Answers

'Ought to save' correctly retains 'to' before the base verb, unlike most other modals.

'Ought we to inform' is the traditional (though now less common) question form retaining 'to'.

As a modal auxiliary, 'need' in the negative ('needn't') is followed directly by the base verb without 'to': 'needn't worry'.

As a main verb, 'need' takes 's' for third person singular and is followed by 'to + base verb': 'needs to finish'.

As a modal in questions (especially formal/British usage), 'need' is followed directly by the base verb: 'need you go'.

'Needn't have + past participle' expresses that an action was unnecessary but was done anyway: 'needn't have worried'.

In affirmative statements/questions, 'need' typically functions as a main verb: 'do you need'.

As a modal, 'dare' in the negative ('daren't') is followed directly by the base verb: 'daren't speak'.

As a main verb, 'dare' takes 's' for third person singular and is followed by 'to + base verb': 'dares to challenge'.

Both the modal form ('Dare you question') and the main verb form ('Do you dare question') are grammatically accepted, depending on formality.
