Final answer:
To convert 'The children play outside now' into present simple, the positive form is 'The children play outside', the negative is 'The children do not play outside', and the question is 'Do the children play outside?'.
Step-by-step explanation:
To change the sentence "The children play outside now" into positive, negative, and question form in the present simple tense, we first acknowledge that the statement is currently in present continuous due to the use of 'now.' However, for present simple the sentence changes as follows:
- Positive: The children play outside.
- Negative: The children do not play outside.
- Question: Do the children play outside?
When constructing these sentences in present simple, we omit time-specific adverbs such as 'now' that imply continuous action, and instead use the bare infinitive form of the verb ('play') for positive statements, add 'do not' before the verb for negative statements, and invert the subject and 'do' to form questions.
