Question words (also called interrogative words) are words we use to ask questions. <em>How </em>is one of them.
Negative sentences are usually formed by adding the word <em>not </em>after the auxiliary verb (in the second question - after <em>are</em>).
We use the phrase <em>used to </em>to talk about things in the past which are no longer true. In the third sentence, <em>at one time</em> can be omitted because, if we use <em>used to</em>, it's understood that something happened at one time.
When we're converting passive voice into active voice and don't know who the subject is, we can use <em>they </em>as the subject.
Direct speech quotes someone's words directly - in the exact way they were spoken.
Tag questions are questions we ask to get confirmation. We attach a tag question to the end of a statement, turning the entire statement into a question. If the main clause is positive, the tag question will be negative (and the other way around).
