On this show , we explore words and expressions in the English language . We can also tell where they come from . And probably more importantly for those learning to speak English , we explain how and when we use these terms . Reading is a popular activity for people all over the world . There is nothing quite like getting lost in a really good book . It can be a special experience . Minor problems melt away as the characters in the story seem to come to life . The best part about books is that they can take you anywhere you want ! They can take you to places that do not even exist . We can also understand the world around us and its people better by reading stories . So , it is no surprise that Americans sometimes use expressions involving the word "book ." Today we will talk about two such terms . Both use the two main verbs you need when talking about a book -- "reading " and "writing ." Let us begin with an expression from a reader's point of view . Yet "to read someone like a book " means that you know the person very well -- and usually not in a good way . We often use this expression in special situations . A person may be trying to trick you , but you know their true objectives . In other words , you can see through their attempts to fool you or someone else . Now , let's hear how this expression is used in this exchange between two co-workers . Were you able to get him to agree to the deal ? He didn't sign the agreement . Without his signature , we cannot make the movie . Don't you think I know that ! I thought it was a sure thing . He said he was really interested . So , I took him to dinner . I spent a lot of money on a bottle of wine . I even offered him front row seats to that sold-out show next weekend . And he still didn't sign . If you ask me , he had no interest in signing the contract . He just wanted a free dinner and more ! Yes , he read you like a book . So , that is an expression with the verb "read ." Now , let's turn to one with the words “to write .” When you become an expert at something , you may write a book about it . After all , many experts write about what they know . They want to share their expertise or make a name for themselves . In any case , we use the expression to write the book on something to describe a person who knows a lot about something . And this person does not need to have published an actual book . But it can be funny to tie the two together , like in the following example . What's keeping you so busy these days ? I haven't seen you in weeks . I am studying for my exams on building materials . But I'm having a lot of trouble . I'm not sure what materials are the best or worst for natural disasters . You should talk to Madeline . Is she good with building homes in disaster areas ? Are you serious ? She is THE leading expert on building for natural disasters , from earthquakes to hurricanes . I had no idea . She wrote the book on the subject – literally and figuratively . In fact , do you want to borrow her book ? I have a copy . And please give her my number . I would love to pick her brain !
