[Grammar] Unless I make that mistake again, my teacher will get angry with me.

[Son Ho]

Hi, everyone. Could you please help to find a mistake in sentence 1? Either unless or will is incorrect? I have corrected them in sentence 2 and 3. And which one is wrong?

1. Unless I make that mistake again, my teacher will get angry with me.
2. If I make that mistake again, my teacher will get angry with me.
3. Unless I make that mistake again, my teacher will not get angry again.

Unless I make that mistake again, my teacher will get angry with me.

You are right; unless does not go with will in #1. It means that your teacher will get angry if you do not make any more mistake - which is illogical.
Your corrected sentences in #2 and #3 are okay.

Where did you find these sentences? You've been asked in a couple of other threads to identify the source of these sentences.

These sentences are from an English test for students in grade 10 in Vietnam. I think you probably don't know these books published in Vietnam which sometimes contain grammatically incorrect sentences by Vietnamese teachers. That's why I have to ask a foreign teacher and don't know how to explain to you all.

It doesn't matter whether we "know" the books or not. Copyright laws require you to state the title of the book and the name of the author(s).

Then these sentences are from an English test for students in grade 10 in Vietnam. Could you please tell me which one is incorrect?

Only number two is correct and natural.

Son Ho, you still haven't given us the title of the book and the name of the author. Any future posts that don't include that information will be deleted.

I'm so sorry but I have already answered your question. How can I know which book these sentences come from in a test by a Vietnamese teacher who I don't know. The only answer that I can give you is these sentences are in an English test.

 

[emsr2d2]

OK, I thought you meant it was a book full of grade 10 tests, and therefore would have a title and an author. In future, please provide the source in post #1, even if the source is "This question was in a test. I didn't get it from a book".
