most guides are freelance and are hired for particular jobs. tour operators and other people employ guides mainly to inform tourists about the places they are visiting. therefore a guide has to have a good sound knowledge not only of a particular place but also of other things which are generally relevant-for example,architecture,history,and local customs.during our training we learn about a whole range of subject,and we have to be capable of jumping from one topic to another topic in the same sentence but the way in which a person conveys this knowledge is the key you have to be good at judging what your audience is interested in and you have to keep their attention.these are not easy skill,I can tell you.
