Understanding Question Tags for Suggestions

A question tag is a short question added at the end of a statement. It is usually used to confirm information or to seek agreement. The type of question tag used depends on the main statement.

Forming Question Tags with 'Let's'

When a sentence begins with 'Let's', which is a contraction of 'Let us', and it's used to make a suggestion or proposal, the standard question tag is 'shall we?'.

This is because 'Let's' implies a proposal involving the speaker and the listener(s), making 'shall we?' the most appropriate tag to seek agreement or confirmation.

Analyzing the Given Sentence

The sentence provided is: "Let's all go to the beach this evening, __________."

• The sentence starts with 'Let's', indicating a suggestion or proposal.
• The suggestion is for 'us' (the speaker and others) to go to the beach.
• We need a question tag that asks for agreement on this suggestion.

Choosing the Correct Question Tag

Based on the rule for sentences starting with 'Let's' used for suggestions:

• 'do we?': This is typically used for statements in the simple present tense. Example: "We go to the beach often, do we?"
• 'don't we?': This is used for positive statements in the simple present tense. Example: "We are going to the beach, aren't we?" (Note: This example is slightly different, 'aren't we?' fits better here, but the point is 'don't we?' needs a different structure).
• 'shall we?': This is the correct tag for suggestions or proposals starting with 'Let's'. It directly matches the intent of the sentence.
• 'aren't we?': This is used for statements with 'are'. Example: "We are going to the beach, aren't we?"

Therefore, the correct question tag for the sentence "Let's all go to the beach this evening, __________." is 'shall we?'.

Final Answer Construction

The complete sentence with the correct question tag is:

"Let's all go to the beach this evening, shall we?"
