is this the man that you want to have repair the radio for me

这是一个一般疑问句,如果看不懂的话,可以将它变为一个陈述句：this is the man that you want to have repair the radio for me.从that引导的定语从句开始看,want(想)是个动作,have repair the radio for me（为我修收音机）也是一个动作,两个动作连接再结合want的用法,肯定中间需要to.另外,在have repair the radio for me少了一个宾语him,整体来看应该是have him repair the radio for me,但因为这是一个定语从句就把him省了.总之,后面的句型就是sb want to do sth,这里的do表示have him repair the radio for me.
