You told me（that）you didn't have a boyfriend. 这里的that可以省略吗？为什么？

可以省略 宾语从句中that一般情况可省 ,但也并不是任何情况下都可以省略。 具体如下： 宾语从句 1． 定义：用作宾语的从句叫宾语从句。 2． 构成：关联词+简单句 从属连词that。如： He told u俯憨碘窖鄢忌碉媳冬颅s that he felt ill. 他对我们说他感到不舒服。 I know he has returned. 我知道他已经回来了。(that省略) 注:宾语从句中that一般情况可省 ,但that在引导宾语从句时也并不是任何情况下都可以省略。在以下情况下，that不能省略。 1． Everybody could see what happened and that Tom was frightened.(and连接两个宾语从句，that宾语从句放在and的后面时，that不能省略。) 大家都会看出所发生的事情并知道Tom非常害怕。 2．I know nothing about him except that he is from the south.(that引导的宾语从句作介词宾语时，that不能省略。) 对他我一无所知，只知道他是南方人。 3．That he ever said such a thing I simply don’t believe. (that从句位于句首时，that不可省略。) 我简直不相信他曾说过这样的话。 4． We decided, in view of his special circumstances, that we would admit him for a probationary period. (主句谓语动词与that从句之间有插入语，that不可省略。)

可以省略 这是定语从句,也有宾语从句等。记住,在从句中that都可以省略。但像you told me why you lost your way. 例如why,what,how…引导的从句这些东西不能省略,只有that可以省略

as, 指的是“正如，就像我告诉你一样” as sb told you as someone said 是比较常用的写法 这里when表示在...时候，明显不对。
