【1】I told them （not everybody could run as fast as you did）,didn't 这句话括号内我着看是直接宾语部分,但好像也是个省略that的宾语从句,请问宾语从句能作直接宾语（构成双宾语）吗?【2】 I don't know (how long )he has stayed here.请把括号内的部分变成强调句的部分,也就是说改成强调句.但是答案给的：I don't know how long it is that he has stayed here .怎么改成这个样的我想着是it is how long that i dont know he has stayed here
