She was very set in her ways when she first tied the knot and wasn’t happy when she didn’t get her way. She looks happy now, though, after learning relationships are all about compromise. He is usually nice but also set in his ways and sometimes becomes cranky when he doesn't get his way. As a stylistic preference, I'd usually avoid repeating "way" so an alternative ending to the bottom sentence could be "when he doesn't get what he wants." A similar change could be made to the 1st sentence at the top.

I would say none of the above. Number 5 needs an "and" added "I can celebrate Christmas, New Year, and my birthday in winter." However, I would say something like "In winter, there's Christmas, New Year, and my birthday."

Saying "there is a hope" sounds very formal and stilted. "There is hope" is more natural. In real life, I would probably say "We will not hunt endangered animals and we hope that they can live in forests."

I agree with Gray. I would normally say "do you anticipate," in most circumstances, though, because "are you anticipating" sounds a little more formal.

Either one could technically be correct, but the first one is a lot more likely. Usually, this is something that would be said by an event host, right before "tonight's speaker" starts speaking. That means that the event host is speaking to the audience, and is about to describe the background of the event speaker. In this case, they would say "Let me introduce you to tonight's speaker." To make the second one correct, the event host would have to say a little bit about the background of the audience TO the speaker.

I don't have suggestions, but "housekeeping" generally means cleaning/tidying. So "housekeeping expenses" would refer to something like maid services and not rent/mortgage/insurance/maintenance/groceries/utilities/etc.

Just to clarify from Elena's answer on number 3: You can't replace just one "could" to "will" (e.g., The sentence "Joe, you couldn't give me a hand, will you?" is incorrect). You could say "Joe, you wouldn't give me a hand, would you?" and the meaning would be just as polite as the original, although it is less commonly used. Bottom line: the verb in the second (question) part of the sentence has to match the verb in the beginning of the sentence. There isn't really a way I can think of to use this kind of reaffirming question sentence construction with the word "will." To use "will," you'd have to ask a direct question (e.g., "Joe, will you give me a hand?")

I would change it to "One of the first warning signs..." because you're using the singular "is" verb. If you use the word 'Among' as a subject for the sentence, you would have to use a plural verb (and therefore change the last part of the sentence accordingly."
