14.have(has)不是表示“有”的意思,并在句中做谓语时,其反意疑问句的助动词要用do, does, did。例如:
They had a meeting just now,didn't they? 他们刚才开了个会,是吗?
15. 陈述部分有have to 时,其反意疑问句要用助动词的否定形式。例如:
You have to water the vegetables every day, don't you?你每天都要浇菜,对吧?
16. 陈述部分是there be句型时,其反意疑问句中要用there。例如:
There was a hospital here, wasn't there? 过去这儿有家医院,是吗?
17. 陈述部分有had better时,反意疑问句中要用hadn't。 例如:
We had better go to school at once, hadn't we? 我们现在最好马上去上学,好吗?
18. 当陈述部分含有情态动词must时,我们便要分析一下must的含义。如果must 作“一定;要;必须”讲,反意疑问句须用mustn't或needn't;
而当must作推测意义“一定 是;必定”讲时,反意疑问句则需根据must后的动词原形选用相应的形式。例如:
He must work hard at physics, mustn't he? 他必须努力学物理,是吧?
Tom must be at home,isn't he? 汤姆一定在家,是吧?
