It’s up to you how much information you would like to share. Because it’s a yes/no question, you could simply say “yes, they do” or “no, they don’t.” In friendly conversations in English, most people would reveal more information than a yes or no, however. You might expect to hear “yeah” and some anecdote about the number of smokers, or a person who smokes or used to smoke. For instance: “yeah, my uncle used to smoke for ages but eventually gave it up.” Or “um, yeah, my dad smokes but not my mom. In my country, a lot more men tend to smoke or drink than do women, so that’s kind of how it’s been in my family too.” Or whatever. By simply saying “yes” or “no” and a corresponding tag “they do” or “they don’t”, you could be communicating that you don’t think very highly of the subject and might enjoy changing it to something else. You could answer with “yeah it’s kind of a mixed bag, what about yours?”, which suggests that it’s a casual subject you don’t feel very strongly about. Because of outside circumstances and context, it is hard to give you a better set of possible practical answers without exhausting all possible answers, which will most likely only come with proficiency from living in an English-speaking country. Finally, don’t forget, with a new language comes new cultural normes. Good luck 👍

To be at work To get off (of) work (no preposition) Because of the noun work (like a few other very commonly used nouns, such as house, church, hospital, etc), the preposition or lack of preposition used with the corresponding verb is sometimes different than with other nouns. There are also regional differences in English that complicate this already-subtle point. To go to work (the place) To go home To leave work To leave home To be in the hospital (American English) To be in hospital (British English) To finish work (the activity) To get to work (the place) To get home Etc. To see more explanations on these kinds of problem (preposition, article, verb choice, etc), you can look into the In-Use series, by Cambridge. For instance, Grammar In Use, (and the corresponding level). Likewise, Vocabulary In Use would be good. Don’t forget to buy the most recent edition. This particular series does not publish very many guides for American English, but often enough, the differences are minuscule. However, if you would like to improve your understanding of phrasal verbs, Oxford has a good publication, entitled Idioms and Phrasal Verbs (which are mostly American). For all students and teachers of English: Always try to use official, authoritative guides. You can find a lot of free material online; however, it is often full of mistakes or of information you cannot be certain is authoritative and up-to-date.

Typically, in a professional setting, any such general, impersonal message would read: “thank you for your understanding and support.” In an even more impersonal setting, such as a large corporation, depending on the sector, it could say “comprehension” instead of “understanding”. Nearly no professional settings would have signs for staff that start with “I wish”, nor, “I hope”. “I hope” is used in vernacular English and in informal settings, not professionally. “I wish” is also reserved for conditional sentences; however, in some situations it is used personally and intimately—such as on a birthday card—but this would also be wrong for the setting because the sign is not meant for a specific person you know so well but a group of people you likely do not know very well (judging from the nature of your message). Additionally, to say “I wish you” is often followed by abstract nouns that tend to be ideals, such as happiness, prosperity, luck, etc. Hence, “understanding” and “support” simply don’t work with said usage. In a more personal space, with a small team, you could say “I hope everyone understands and can lend some support”, but if it’s a bigger space or less personal milieu, you could expect the passive voice or some such structure: “your understanding and support are greatly appreciated/mean a lot/etc.” There are many variations, and sometimes voice, as well as verb and noun choice, imply radically different settings to native English speakers. I.e. the way you cast your sentence has a big impact on your audience because of their living relationship with the language. If they are non-native English speakers, you might simply say “your support and understanding are greatly appreciated”, which generally would work well regardless. :-)

It is not a collocation. A collocation is a pair of words that occurs frequently or in a fixed way. For example if I say "vice" you might say "versa." If I say "foot," you might say "ball." These are collocations. A dictionary of collocations can be consulted for free online, at Oxford, for example. Here: https://www.freecollocation.com/ By regularly consulting such reference books, you will improve your syntax in English significantly. To give someone a lift is a phrase that means to drive someone somewhere, especially by car.

Just to let you know guys, in English we don't say Farsi but Persian. Farsi is sometimes used to distinguish between the dialect of Persian in Tehran and that of Afghanistan, but technically speaking, that's actually only within the Persian language. In English, we say a Persian rug, not a Farsi rug. A Persian cat, not a Farsi cat. In 2011, the Academy of Persian published an article on the heritage of the word Persian, saying that replacing Persian with Farsi would ruin thousands of years of the word's heritage. Indeed, they are right. In addition to this, Farsi is actually the same word as Persian, but because of Arabic occupation in the region, the Arabic version was introduced into the Persian language. The reason there is an F and not a P is because Arabic has no P, but only F. This is known as a transliteration. Hence, when you say Farsi in English, you are actually saying Persian (parsi, farsi) transliterated two times, from Arabic to Persian, and from Persian to English. What's more, this is only a dialect of Persian, not a language. In linguistics, this is known as an endonym, which is a place or language name used within a language (rather than externally).
