问题描述：
who are you waiting for?是主谓宾但是his job is cleaning the office.却是主系表,
不要解释成主谓宾是什么主系表是什么.
答
这里是要看谓语是什么，are waiting 只是wait这个动词的现在进行时，who是谓语的宾语，所以是主谓宾。
his job is cleaning the office这句话里面cleaning是一个动名词，cleaning the office是一个动宾短语作表语。如果说成He is cleaning the office那就是主谓宾了
答
变为陈述句是you are waiting for who?
这里的are doing表示的是时态！现在进行时！、
所以是主谓宾
his job is what?这里是is是是的意思。是主细表：）
hi我 还不明白
答
who are you waiting for?的一般现在时是“Who do you wait for?”这下楼主可明白为什么说它是主谓宾结构吧?
His job is cleaning the office 是一般现在时.这里的cleaning是动名词,与前面的is连在一起组成表语.
答
wait是谓语动词,who是宾语,you为主语
is是系动词,引领表语cleaning the office,his job是主语
