i think he have been arrived?arrive不是不及物动词吗?怎么后面不用接介词呢?

我不懂!不是一般的不及物都要接介词才可以吗?象I don't know what you are talking about!
答
不及物动词就是不能直接加宾语的动词,必须要借助介词才能加宾语.比如arrive in Beijing不能说arrive Beijing .但如果不及物动词（包括arrive）后没有宾语的话,就完全可以什么都不加了.因为英语的句式有S+V（主语+谓语结构）She arrives.
而您的例子I don't know what you are talking about!是宾语从句,what在从句中做介词about的宾语.
