I asked him what had happened 为什么要用had happened 而不直接用happene

I wanted to know_to him.为什么填what happened而不是what has happene He asked what had happened with me. ___I saw him,I knew what had happened. What had happened?What had happened?What had happened? DONGGUO ASKED HIM FOR HELP AND TOLD HIM WHAT HAD HAPPENED what do you think had happened to him. 这句话在语法上怎么用句 what happened to him yesterday.为什么要用happened?happen可以吗 what is wrong had happened? I didn’t know what had happened to him 有语法错误吗 the girl was able to explain what had happened.不是被动语态为什么用was the man stopped me and asked what had happened能去掉had吗 what had happened和 what has happened有什么区别
