that...[名词子句]... 是在叙述一件事情, that 没有意思 that子句...做S词 that 不可以省略 that子句... 做O词 that 可以省略 (V) glad, sure, sorry... 引导that...[名词子句] I am sure that he will succeed.
1:陈述句用that连接 比如:He said that he was a middle school studen。 2:weather解释为“是否”,改变为宾语从句时,要用陈诉句语序 比如:I want to know if (whether) he lives there. 尽量简单些,希望对你有帮助。
