高考英语里宾语从句可是必考语法点，不懂它可不行！想知道宾语从句有啥常见形式，啥时候that从句不能用，还有否定转移咋回事吗？快跟我一起学，包你轻松掌握！
先说说宾语从句常见形式。作动词宾语时，有几种情况。一种是由that引导，that很多时候能省略，比如“I heard that he joined the army.” ，也就是“我听说他参军了” 。
还有由what、whether（if）引导的，像“She did not know what had happened.” ，意思是“她不知道发生了啥” ；“I wonder whether you can change this note for me” ，就是“我想知道你能不能帮我改下笔记” 。
另外还有“动词＋间接宾语＋宾语从句” ，比如“She told me that she would accept my invitation.” ，即“她跟我说会接受我的邀请” 。
作介词宾语呢，举个例子，“Our success depends upon how well we can cooperate with one another.” ，意思是我们的成功得看大家合作咋样。作形容词宾语也不少见，像“I am afraid (that) I’ve made a mistake.” ，就是“我恐怕犯错了” 。
注意哈，that引导的从句常跟在anxious、aware这些形容词后面作宾语，有时候也能看成原因状语从句呢。还有哦，it能当形式宾语，真正的that从句在句尾，比如“We heard it that she would get married next month.” ，就是“我听说她下个月要结婚了” 。
再讲讲that从句不能用的情况。有些动词不能直接跟that从句，像allow、refuse这些，它们后面可以接不定式或者动名词，比如“I admire their winning the match.” ，但不能说“I admire that they won the match.” 。
还有些动词不能用在“动词+间接宾语+that从句” 结构里，像envy、order 等，正确的是“He impressed the manager as an honest man.” ，而不是“He impressed the manager that he was an honest man.” 。
最后，宾语从句还有否定转移。要是主句谓语动词是think、consider这些，宾语从句有否定意思，通常把否定词挪到主句谓语上，从句用肯定式，比如“I don’t think this dress fits you well.” ，就是“我觉得这衣服你穿不合适” 。
