up to now 的同义词组为：so far ,till now ,untill now(这三个词组都是现在完成时的标志词,即他们出现时,句子常用现在完成时)
He has begun his own private'telephone' service.时态为现在完成时 ,助动词为has,否定句在Has 后加not,即 He hasn't begun his own private'telephone' service.一般疑问句：Has he begun his own private'telephone' service?肯定回答：Yes,he has.
另外,看您提的以上问题都是关于现在完成时的具体问题,以下建议您可能用得着：
1 现在完成时的句子结构为：have/has + 动词的过去分词,其中have/has为助动词.
2 一般的陈述句变一般疑问句时,常把助动词提到句首,再加上其他内容,句尾的句号变问号.肯定回答是：Yes,主语（常为人称代词,如you ,i ,he,she等）+助动词
还有什么问题,望追问.

一般过去式
what did the bird do in three minutes?
up to now: till now , so far等等
现在完成时态
助动词has
否定句在has后加not
一般疑问句将has和he颠倒
肯定回答：yes，he has
what has he begun？

时态为一般过去时。What did the bird do in three minutes? 时态为现在完成时。助动词是has.
He hasn't bugun his own private telephone service. Has he begun his own private telephone service? Yes,he has.What has he begun?
