I can explained everything __I can to you.为什么用I can explained everything __I can to you.为什么用that.不用what
问题描述：
I can explained everything __I can to you.为什么用
I can explained everything __I can to you.为什么用that.不用what
答
that 引导定语从句修饰everything 在从句中做I can（explain）的宾语
答
that引导的是定语从句。先行词是不定代词everything，引导词用that。
句意为“我可以把我能解释的都解释给你听。
如用what，则应为：I can explain what I can to you.（everything that=what）
另外：原句有错误，can后应为动词原形explain；that I can to you并没有错误，只是省略了explain一词，补全应为：that I can explain to you.
仅供参考，O(∩_∩)O~
答
定语从句 everything做先行词 从句不缺成分 用that
定于从句连接词没有what
答
楼主好,
因为先行词是不定代词Everything, 就要用that.
还有像someone, everyone, anyone这些都要用that连接
希望对你有帮助^^
答
that 引导的定语从句,如果用WAHT,应该是I can explained what I can to you
答
这里是定语从句。先行词是不定代词everything，引导词用that。
句意为“我已经把我能解释的都解释给你听了。”
