In this final lesson on writing a letter of application, students learn the importance of a cover letter and its role in job applications, particularly for summer jobs. The instructor walks through the structure of a cover letter, emphasizing the need for a clear header, a greeting, an engaging opening paragraph, and a closing that expresses gratitude. Using a specific example for a job at Culture Tours, students are asked to apply by writing a letter of application detailing their suitability to guide foreign students in Malta, with a focus on making local attractions appealing. The lesson also includes reading a sample cover letter with intentional mistakes for correction and discussion.
