Answer:
Affirmative: We must take all this stuff with us to the park.
Negative: We mustn't take all this stuff with us to the park.
Interrogative: Must we take all this stuff with us to the park?
Explanation:
According to the instructions, we need to use "must", "we", and "to take" to form the sentences. Also, every sentence will end with "all this stuff with us to the park."
Since "must" is a modal verb (a type of verb that helps another verb to express obligation, suggestion, possibility, ability, etc.), it does not change at all, no matter who the subject is, or if the sentence is affirmative or interrogative. The only thing that can happen is its contraction with "not" in the negative: "mustn't". In the interrogative form, "must" will be placed before the subject of the sentence. The main verb in the sentence, the one that follows "must", does not need to be preceded by "to".
Take a look at the examples below:
- She must think I am silly.
- You mustn't make so much noise!
- Must we call her?
