1、The scientist made the great invention when he was over seventy.(保持原句意思）
The scientist made the great invention in _____ _______.
2、will 和be going to是不是都不能和have连用?（比如不能用will have）还是一个可以一个不可以?
3、像反意疑问句前半句是have的时候,什么情况下后半句用助动词,什么情况还用have?

1、in his seventies
2、都可以啊.
比如：I will have lunch after school.我放学之后吃午饭= I am going to have lunch after school.
3、当have 是助动词时,没有任何意义,用于完成时态.反意疑问句用haven't或hasn't;
当have是普通的实质意义的动词,表示“吃,有”等意思的时候,那就得用助动词do或does来帮忙完成,即don't ,doesn't.
例子：I have finnished my homework,haven't I 我完成了家庭作业,不是吗?
I have dinner at 6 p.m every day,don't I 我每天下午6点吃完饭,不是吗?
She hasn't cleaned her room,has she?她没有打扫她的房间,是吗?
He doesn't have an apple in his bag,does he?他的包里没有苹果,是吗?
再问：不是不能用They will have meeting.吗？
再答：可以用的。是不是老师在介绍用法的时候，你听错了。 have 有几个词性，不同的词性不同的意思。当做实意动词的时候，表达“有，吃，进行，从事，干”的时候，可与任何时态搭配，所以包括你问的那句will have a meeting。当做祈使动词的时候，表达“让，命令，使”的意思，固定搭配have sb do sth. 让某人干某事。当做助动词的时候，无实质性意思。通常用于完成时态，包括过去，现在和将来完成时。 have done sth, had done sth, have been doing sth, have been done sth, will have done sth等。所以，have是可以和will , be going to表示将来意义的词一起用的。
