To change sentences into yes/no questions, you typically need to rearrange the sentence structure to place an auxiliary verb at the beginning. Hereโs how you can convert each of the given sentences into yes/no questions:
He has started several projects. Has he started several projects?
He has bought a computer. Has he bought a computer?
We were cycling home. Were we cycling home?
You need some shirts and pants. Do you need some shirts and pants?
Mr Sahani kept busy. Did Mr Sahani keep busy?
They tried to run away from the park. Did they try to run away from the park?
She called him a fool. Did she call him a fool?
You are going to Pokhara tomorrow. Are you going to Pokhara tomorrow?
He broke his hand on Saturday. Did he break his hand on Saturday?
Her parents weren't at home. Were her parents not at home?
In these sentences, when present perfect or past actions are expressed, we use auxiliary verbs like 'has', 'were', and 'did'. For sentences with 'are', transforming them involves swapping the subject and verb. This structure allows us to turn affirmative statements into questions that can be answered with 'yes' or 'no.'
