這是一個(gè)一般疑問(wèn)句,如果看不懂的話,可以將它變?yōu)橐粋€(gè)陳述句：this is the man that you want to have repair the radio for me.從that引導(dǎo)的定語(yǔ)從句開(kāi)始看,want(想)是個(gè)動(dòng)作,have repair the radio for me（為我修收音機(jī)）也是一個(gè)動(dòng)作,兩個(gè)動(dòng)作連接再結(jié)合want的用法,肯定中間需要to.另外,在have repair the radio for me少了一個(gè)賓語(yǔ)him,整體來(lái)看應(yīng)該是have him repair the radio for me,但因?yàn)檫@是一個(gè)定語(yǔ)從句就把him省了.總之,后面的句型就是sb want to do sth,這里的do表示have him repair the radio for me.
