...have not to do, have...?

[notletrest]

1. " Anna hasn't to go to school on Sunday, has she?" Zhang Zheng-bang p.791
Is it right?
2.Scientists have yet to create (= have not yet created) the mechanical version of science fiction, have they?

Is 2. right, too? If not , what's right?
3.Please tell me the difference between " hasn't to go " and "have not yet to create" in structure.

Thank you indeed!​

#2 is correct. #1 is not natural in modern English, it would be natural as: "Anna doesn't have to go to school on Sunday, does she?"

Neither is right. bhai has told you we don't say the first.
You haven't given an example of the second. Did you mean "have yet to create"?

For 1. in China , Zhang Zheng-bang is a famous grammarian. So I agree with him. But your idea I more respect.
For 2. bhai is in favour. But I don't think so. Because, according to bhai' s explanation to the sentence "

Scientists have yet to create (= have not yet created) the mechanical version of science fiction", thses two "have not to do's" are not in the same meaning. The first " have to " in the first sentence, means "needn't". The seconde " have yet to ,ie. have not to, we can say, I don't know iis meaning. Please tell me!​

We should say like this:

Scientists have yet to create the mechanical version of science fiction, do they? Is it right?​

For3, I give you the example:

Scientists have yet to create the mechanical version of science fiction.
Thanks much!​

I have had a quick look at some of his lectures. He seems to be fairly sound, but he's not infallible.

. For 2. [...]Scientists have yet to create the mechanical version of science fiction, do they? Is it right?

No. The tag should be 'haven't they?'

 

[birdeen's call]

No. The tag should be 'haven't they?'

Isn't "don't they" possible too? :-?

Not for me. It may be for some.

It depends on your definition of what is "right".

"Anna hasn't to go to school on Sunday, has she?" could certainly be adjudged syntactically correct - depending on your criteria for syntactic correctness.
But no native speaker would ever say it. That makes it "not right" in terms of usage. ​

​

• Please read: "The most severe weather is yet /still to come. The implcation here is negative, has not yet come." Randolph Quirk p.143
  So the tag should be " have they ?“, just as bhai and 5jj said in the above. I wonder why 5jj changed his view here.
  Writing here reminds me of a Chinese saying : A drunken man's intention does not lie in wine. Maybe you don't know the meaning of it, because I put it into English word for word. My real meaning I'll tell after solving the problem.
  Thanks!

​

• No. The implication may be negative but the construction is affirmative. Unlike the such words as 'rarely' and 'seldom', 'yet' is not a negative word. The tag in the original should 'haven't they', as I said.

  I didn't.

​

I have to accept your view point above.
But it reminded me of the sentence " If scientists have yet to create (= have not yet created by bhai) the mechanical version of science fiction, they have begun to come close." again. What in the world is the meaning of " have"? How does the "to create" turn into its past participle?
Thank you!

It's an odd tense. (I know "tense" isn't technically the write word; it's probably aspect or something else, but for now, let's call it a tense.)

I did some searching, found an old thread in English Forums (one I'd even contributed to), found another grammar page that referenced that same thread in EF, and a bunch of grammar sites that refer to the "future tense" using the phrase "have yet to happen" but without explaning that constructoin itself.

I haven't done X yet = I have yet to do X.
It hasn't started raining yet = It has yet to start raining.
I haven't started my Chrismast shopping yet = I've yet to start my Christmas shopping.

I don't know why, but that's the way it works.

Hello.:-D
Well, I feel "have yet to..." is similar in construction to "have to..."
Therefore I think it is in the present simple tense.

It might be wrong, but my interpretation would be:

"I have yet to do X."
= "I haven't done X yet, so I have to do it (later on)."
or "I haven't done X yet. I still have to do it (later on)."
(However, I must admit the fact that it doesn't (necessarily?) mean "obligation".)

I don't think it (=have yet to...) is in the present perfect tense.
"future tense"....hmm...I'm not sure.
:-D

Your bracketed last line is the important one. HAVE yet to and HAVE to appear similar, but the former does not suggest obligation and the latter does.

The following note may be confusing for some learners. Don't worry about it. It is written for those interested in the technicalities of grammar.

Most writers on grammar these days accept that there in no future tense in English, at least in the sense of inflected forms. Thus ALL of the following are, formally, present tense, simple (i.e., not progressive or perfect, unless otherwise stated).

I do it tomorrow.
I have to do it tomorrow.
I am to do it tomorrow.
I have yet to to it
I am doing it (progressive) tomorrow.
I will do it tomorrow.
I am going (progressive) to do it tomorrow.
My mother will be happy if I have done (perfect) by tomorrow.

If you have questions about this, please start a fresh thread. The only thing that is directly relevant to this thread is my confirmation that have in I have yet to do it is present tense.

Among all the answers, I like yours best, because it is most to the point and very objective,too.

And thank you for ignoring my "write word" instead of "right word" -- I've been doing a lot of this on my phone lately and I've been making more mistakes than usual!

Please don't care about it. You are too strict with yourself.
