一、寫信動機
通常求職信是針對報紙上招聘廣告而寫的。因此，信中須提到何月何日的`報紙，有時工作機會是從朋友或介紹所聽來的，不論哪一種，求職信上一定要說明寫信的緣由和目的。
因此首先應該表明你是在何家媒體看到應聘廣告以及所要應聘的職位。參考例句：
reply to your advertisement in todays newspaper,i respectfully offer my services for the situation.拜讀今日xx報上貴公司的廣告,本人特此備函應徵該職位。
ying to your advertisement into- days issue of the(newspaper),i wish to apply for the position in your esteemed firm.拜讀貴公司在今日(報紙)上廣告,特此備函應徵貴公司該職位。
