This week on the 'Booking through Thursday' blog(http://btt2.wordpress.com/2008/04/17/vocabulary/)
we are asked to describe what action we take on finding a word in text that we don't understand.
Well if I literally can't put the book down then I'll leave the dictionary work till I'm finished. That is as long as I can follow the rest of the book. I'd probably jot it down and keep it in the front of the book.
