be shown the ropes
To be taught how to do or perform a job, task, or activity; to have explained or demonstrated how something is done. I had never worked on a ranch before, but I was shown the ropes by a friend of mine. This is Samantha, our new intern. Make sure she's shown the ropes by the end of the week.
in a bad light
Negatively; under unfavorable circumstances. (Typically used with the verbs "see" or "show," or some similar variation.) I'm flattered that he based a character in his novel on me, but I think I was shown in a bad light. The once-beloved mayor has been seen in a bad light ever since news of his tax-evasion scandal came to public attention.
show the flag
To stand up for, support, or defend someone or something. A number of people from the actor's hometown are arriving into New York to show the flag at his debut performance on Broadway. My country is often a target for insults or gibes abroad, so whenever I go traveling I make a point of showing the flag for it.
