问一个cover letter的问题, please help!

Cover letter must cite examples of past work as a self-starter,
ability to work under deadlines, and flexibility to work both independently and as an integral part of our Project Engineering Team

上面是要求,不太明确这个cite examples of past work应该如何把握,如果是举例子的话好像显得很长,像讲故事的,有什么template可以提供吗? 我还是第一次看到这种要求的.
