带有have to变一般疑问句把have提前吗 带有have to的句子,比如说I have to do my homework这个句子变成一般疑问句是Do you have to do your homework?还是Have you to do your homework?呢,我朋友的老师说要把have提到主语前面,但是我记得是加助动词do的...本人知道现在完成时.
不能提前. have to中的have是不能做助动词的. 否定:don't/doesn't have to 疑问:Do/Does+主语+have to...? have got to中的have是可以做助动词的. Have you got to leave? I haven't got to leave. have做“有”的意思时,可以当做助动词用的. Have you any money?=Do you have any money? I haven't any money.=I don't have any money. 至于现在完成时,have/has就是助动词,是可以提前的.
