　　例句：

　　These unilateral developments differ in their specifics,but they are all designed to tax multinationals on income and revenue that countries believe they should have a right to tax,even if international tax rules do not grant them that right.

　　分析：

　　这句话的主干为these unilateral developments differ in their specifics,之后but后跟了一个并列结构，其中are designed to为被动语态，之后接了一个由that引导的定语从句修饰先行词income and revenue，后接了一个由even if引导的让步状语从句。
