Translation:I want to go to England, I have not been there yet.
I am pretty sure that идти isn't a correct option. Using the perfective (as you suggested) is better, because what you want is "to go to England " and not " to go to England" (the interest being the destination and not the trip).
However, the verb ходить/идти is a verb that expresses motion by foot. Unless you are at the border between Scotland and England, you will more likely be going by any motorized mean and therefore a better verb would be ехать (perfective of ездить), making the first part of the sentence : "Я хочу ехать в Англию".
Anyone is welcome to confirm, infirm or complete my answer.
The perfective counterparts of идти and ехать are пойти and поехать, respectively. The verbs ходить and ездить are both imperfective and refer to regular trips in uncertain direction or regular back and forth trips. One can say, «Я хочу поехать в Англию», «Я хочу ехать в Англию» (the implication is “right now”), «Я хочу ездить в Англию» (on a regular basis) and «Я хочу поездить в Англию» (“I’d like to make a few trips to England”).
Я хочу [поехать] в Англию = I want to go to England
Я хочу побывать в Англии = I want to make a trip to England
Я хочу быть в Англии = I want to be in England (However, I can't think of a situation when anybody would really say that)
Как бы я хотел сейчас быть в Англии! = I wish I was/were in England now (That's a much more likely thing to say)
It isn’t only for traveling. As I said earlier, the equivalents of “to go” are often omitted after the verb хотеть before the noun phrase that refer to the destination. (Examples: Я хочу домой. Она хочет к маме). Interestingly, the verb of movement is not normally omitted after the negative forms of хотеть: Я не хочу идти домой. Она не хочет идти/ехать к маме. The verbs есть/съесть and пить/выпить are usually omitted after various forms of хотеть and those forms of быть that are used in compound future — буду, будешь, будет, будем, будете and будут. Examples: Хотите [выпить] водки? (Would you like some vodka?). Кофе [пить] будешь? Will you have some coffee? Я буду [есть] жареную рыбу с картошкой. (I’m going to have fried fish with mashed potatoes). Talking about food or drinks we often omit the main verb even in negative sentences, especially in the present and future tenses, e.g. «Я не хочу [пить] пива». «Я не буду [есть] суп». When asking permission to take a fruit, a cookie or a candy, we usually omit the verb взять (to take) after можно: «Можно мне конфету?» (= Можно, я возьму конфету = May I take a candy?). Likewise you can say, «Можно ручку?» which means “May I borrow your pen?” Verbs of movement can be omitted after надо/нужно and the words describing the destination: Тебе нужно [сходить] к врачу. Мне надо [идти/ехать] домой (I have to go home). If the object of хочу (and even буду) is a human being, then the sentence is likely to be interpreted in the sense that the omitted verb means “to have sex with”. The fact that «будете» sounds the same as «будите» (= you wake) is key to the following joke: «Вы утром свою жену будите?» «Буду» (In this case, the expected answer was «Бужу» — obviously, the answerer was thinking of «будете»).
Okay, but my point was that Duolingo insists on translating был в стране exclusively as "been to a country" for some sentences and "visited a country" for other sentences. There's no meaningful difference within the sentences, so it's up to the user to memorize the translations that Duolingo insists upon.
«ещё не был» is a simplified replacement of «ещё не бывал»/«ещё не побывал». «Ещё не был» is commonly used these days, although it would probably be considered incorrect 100 years ago. «Ещё не бывал» and «ещё не побывал» (the former means “not been [there] yet, but aware the place is worth visiting”, whereas the latter implies “planning to visit, but have/has not visited yet”) are mostly used in reference to long-aspired trips. «был» only means “been”/“visited” when it follows «ещё не».
Nothing to do with technicalities, just needing a place to voice that tyere is an issue with severity on typos that is not seen in other parts of the course. Even having enetered exact characters through this questuon, I can't seem to progress past it. Can some one please have a look at my other feedback and address the typo severity in this course
This sentence in Russian doesn't make sense. We usually don't say "I want to go to England i have not been there yet? It's a run on sentence. Most would say: i haven't been to England, but id like to go? This poses a question, which the English,/russian poses nothing bu confusion?
