if类省略结构小结一、if从句省略“主语+be”若if从句的主语与主句主语一致，且if从句的主语后跟有动词be，那么通常可以省略if从句的“主语+be”。如：If accepted for this post, you will be informed within a week.= If you are accepted for this post, you will be informed within a week.如果你被接受担任这个职务，将在一礼拜内给你通知。If traveling north, you must change at Leeds.=If you are traveling north, you must change atLeeds.如果你是向北行，你必须在里兹换车。If in doubt, ask your doctor.
