sure that i had passed（原句），但书上说，前面省了being，本来应该being sure that i had passed,

请问为什么省，这是什么语法，如果不省的话，为什么要加一个being , 请高手详解

being sure that i had passed,是一个现在分词短语作状语（其中又包含了一个宾语从句的that i had passed），这个现在分词短语在逻辑上是系表结构的，它代替了一个状语从句：After/Because was sure that that i had passed,

a 意思不说了。 主要是考all 和 every 什么时候能“互换” all the boys 谓语用复数 have every one of the boys 意思是 “各个男同学” 谓语应用单数has b应用has c d 你看跟a不同的地方就错了！～应该不用解释了吧？
