How to form questions in English?

There are two types of questions in English. 

1. YES/NO QUESTIONS (Is Betty at school?)

• they always begin with an auxiliary verb (Do/Does/Am/Is/Are/Did/Was/Were/Have/Will/Would/Can/Could …)
• the answer can be either YES or NO + auxiliary verb = SHORT ANSWER
• example: Does your friend read a lot? → Yes, he does./No, he doesn’t.
• in Slovene these questions begin with “Ali …?”

2. WH- QUESTIONS (Where is Betty?)

• they always begin with a QUESTION WORD (What/Who/Where/When/Why/How …)
• the answer can’t be Yes/No, but a new information, e. g. My car./My mum./At home./In the evening./Because I like it./Very quickly …
• example: Where were you yesterday? → I was at home.
• in Slovene these questions begin with “Kdo/Kaj/Kje/Kdaj/Zakaj/Kako …?”
