If:     The teacher said to the students, "Ice floats on water."   Then did:        The teacher told the students that ice floats on water.     The teacher told the students that ice floated on water.      Are both correct? If not, please explain it to me.

The title may be a bit confusing. See the below example:     The movie (was/is) so good.   The simplest guideline on deciding which tense to use, past tense or present tense, to describe an object comes down to whether the description was only true that that time or is true even to the present point of time.  But now we talking about literary work(movies,books,etc) of which quality tend to stay the same over time, which tense should we use?

Man: What do you think of the view?  Droid: I do not think of it.  Man: I don't think of it. I don't. Droids and apostrophes, I could write a book, except you are... barely a droid anymore.  (c) Deep Breath  I can't understand the difference between do not and don't in this case. I'd be grateful if somebody helps.

Did your team win the football match yesterday?         The weather was very bad, so we weren't playing.   vs     The weather was very bad, so we didn't play.   Is the first one not correct? Why is it?

Can you please explain this to me?          Could you please explain this to me?   I am unable to figure out which to use which situation. I did google, and some posts say they are both the same, even if the second one is more formal. Other posts say could is the past tense of can, but in the above example, I don't think could is used as past tense of can.  What is correct way to use these words?

I was reading about various terms for incorrect words, but they didn't seem to fit.  I saw a post where someone said "what do you like to do when you're board?".  That kind of thing.  Also, would that be considered a mistake in grammar?  I didn't think so, but my friend insists it is.  I'm not sure if there even is a word for that kind of mistake, but was just curious about it.  Thanks!

It can be very cold in winters.   It may be very cold in winters.   What is the difference between these two sentences?  People say when may is used then it means that it may be cold in winters or it may not be cold in winters. In other words, may means 'not sure'.  So does that mean if can is used then it is 100% sure that it will be cold in winters?

Are both expressions correct? If yes, do they have different meanings? It seems to me that I came across both of them in books, but I'm not sure.

There exists this famous idea that if all floating icebergs melt, water level will stay the same (because the water replaced by ice is the volume of the melted ice). Now,   Is this always so, if you allow more exotic forms of ice (take e.g. ice XII with density 1.29) ? Is this always so on/in earth ?   EDIT:  I was looking a possibility that you would have water as a liquid that contains pieces of water as a solid. No land is assumed to exist here. "Ice" is always floating or sunken(if possible).  To reformulate, can Ice be sunken in water in any circumstance (pressure, temperature)?  EDIT 2:  Wikipedia: "Ice VII has a density of about 1.65 g cm-3 (at 2.5 GPa and 25°C)".   And water as an incompressible liquid has a density of 1 g cm-3. This means that ice VII is at the bottom of the "lake" and will expand when it melts. Is this true? And are there environments in earth where this (or similar) can happen?

If we want to say "near the river" or "near the lake" which preposition is more accurate by or at?  I think when speaking about a river or lake by is better. Am I right? I mean when we are situated near by, somewhere close to the river or lake, near the bank of the river or on the beach by-side the lake.

I wanted to know if it is grammatically correct to say:  Either the teacher or the students WAS enjoying the picnic.  I'm talking about a grammatical principle and not a proximity or attraction one.  Thank you so much..

A: "I assume you know how this works."   B: "I am assuming you know how this works."   So if you expect someone to know how to use a certain machine for instance could you say either of the too? I cant make out a difference in meaning so if there is none which would be the preferred choice for most speakers?

Sentence 1: I don’t know if it won't rain tomorrow.  Sentnece 2: I don’t know whether it won't rain tomorrow.  Which sentence sound natural to you? Is there a rule that we should use "if" rather than "whether" when the object clause is negative?  Thank you very much!
