Mary , besides the resume , I think we should also write an application letter .   I think so , but how should we write it ?   I think we should begin the letter with a salutation , and the salutation must be very formal .   Yes , it should be so . Then we should write the body and in the body we should mention the place where we saw the job advertisement .   We should say we are very interested in that job , and we hope to get that job .
