介绍： If you are part of the group which you are addressing, you will be in a position to know the experiences and problems which are common to all of you and it will be appropriate for you to make a passing remark about the inedible canteen food or the chairman's notorious bad taste in ties.
译文：如果你是你讲...

介绍： If you are part of the group which you are addressing, you will be in a position to know the experiences and problems which are common to all of you and it will be appropriate for you to make a passing remark about the inedible canteen food or the chairman's notorious bad taste in ties.
译文：如果你是你讲话对象中的一员，那么你就能了解这个团队成员们共有的经历和问题，而且你对餐厅中难以下咽的食物或老总在选择领带方面差劲的品位品头论足也是无可厚非的。
点睛：本句的主句是由and连接的两个并列的分句，句首的if引导了一个条件状语从句，其中包含了一个由which引导的定语从句，修饰the group。主句的第一个分句也含有一个定语从句which are common to all of you，修饰the experiences and problems。第二个分句的主干为it'll be appropriate for you to make a passing remark...it是形式主语，而真正的主语是不定式短语to make a passing remark about...address在本句中作动词，意为“演讲”。
