No, that's just a silly, pseudo-correction of the idiomatic expression "where you are coming from." In the first place, the expression is too informal for serious writing, and cannot be made formal by "improving" its grammar. In the second place, the belief that an English sentence may not end with a preposition is an error: where you are coming from is correct bas it stands - but informal.
It depends on context. Are you answering a question? Answering a question with a short form of a sentence is a little different than just making a statement.For example:Did you know I am coming to town tomorrow?The email mentioned that.However, if you are just making a statement, you should explain "that".The email mentioned that Karen is coming to town tomorrow.
Suitable for previews and TV-talk, but not good English. It is really a conflation of two expressions: A movie is coming; and It will be here soon.
It is not necessarily incorrect to end a sentence with the word "is", although such a sentence will often sound better when reworded. "Is" is a linking verb and doesn't really carry much of its own information. For this reason ending a sentence with "is" can make the sentence weaker. For example, the sentence "I have found that powerful is what the government is." This would technically not be incorrect. But a much stronger sentence can be constructed by rearranging the sentence and removing the "is" from the end. "I have found that the government is powerful." This sentence is also much less awkward. So, generally speaking, avoid ending a sentence with "is", though doing so is not necessarily incorrect grammar.
Coming
upcoming
Are your children coming home? is grammatically correct.
"From" is a preposition. It doesn't seem like it because we expect prepositions to be followed by some phrase. The grammatically correct version of your sentence would be "From where are you coming?" Prepositions show time (when something happened) or space (where something is located). "From where" is location.
Yes, it is a complete, correct sentence.
This afternoon you are coming to the Laboratory.
No, the correct phrase is "he knew winter was coming." The word "had" is unnecessary in this sentence.
It depends on the sentence: You will be coming to the lab in the afternoon! Are you coming to the lab in the afternoon? This afternoon, you will be coming the the lab, won't you?
No, I prefer: "I am coming to the laboratory this afternoon."
That is a correct sentence.
The sentence is grammatically incorrect but translates as: Why are another people coming to Canada.
The sentence "when you r coming" is not correct grammatically. It should be "When you are coming."
The correct spelling for the word "coming" is C-O-M-I-N-G.
It is correct to say "We look forward to hearing from you." As in the sentence " We look forward to their visit.", the word "to" in this idiom is a preposition followed by a noun/ noun phrase.
