Как правильно использовать выражение by any chance в английском языке?

Ответ от Mashanya[гуру]
Фраза by any chance переводится как случайно или ненароком и используется для того, чтобы сделать вопрос более вежливым и мягким, например, не знаете ли вы случайно. Полный и грамматически правильный текст письма с заполненными пропусками для вашего задания выглядит следующим образом:Dear Peter,Do you know by any chance where Bob is? I would like to find out because I have just heard of a job that exactly suits him, but if he doesn't apply fairly soon, of course he won't get it. I last saw him about a month ago, when he just left his job with the film company. He said he had decided to go to France for a holiday and promised to send me a postcard with his French address as soon as he found a place to stay. But I have heard nothing since then and don't know even whether he went to France or not. If you know his address, I will be very grateful if you phone me. I tried to phone you several times, but your phone didn't seem to be working. Yours,
Jack
