1) I have been in England x I was in England The Present Perfect(I have been) refers to your present that is what it is because of the past, so you use Present Perfect when something in the past affects you present. Ex.: I have lost my book => I don't have the book anymore (it affects you present) I was sick last weekend => It's in the past, you're healthy now.

Hello Mariya. 1. "I have been in England" -> focusing on the completed action (that you have been there) and somehow has an effect to the present. This is called the present perfect tense in English grammar. "I was in England" -> telling an action that happened in the past and has no direct relevance to the present. This is called simple past tense. Another example : "I have eaten my dinner." (More Focusing on the condition that I'm most likely full now). 3. "I lost my consciousness" is the correct one. Just like "I lost my money." Without "was." 2 and 5 both sentences can be used interchangeably.

I was in England means that you were there at the moment you are talking about. I have been in England means that you were there earlier but not now

Have been in = человек был и есть сейчас там. По сути это равнозначно I have been staying/living и обычно употребляется с неким промежутком времени. К примеру: He's been in California *since last week/for two months* и т.д. Have been to = был, видел, знаю и уже вернулся.

1) What is the difference between: A "I have been in England." and B "I was in England." --Use sentence A if you want to also tell us how many times you visited, i.e. "... twice" Use sentence B if you want to continue with a story or follow up with more descriptions about your visit, such as "...when I met my good friend Sally." Without more context it is not clear which is a better option. 2) A "I have been in America." ("I have been in California.") or B "I have been to America." ("I have been to California.") --Either phrase works, probably B is used more often. If you are still currently in America, follow sentence A with the length of time, i.e. "for three weeks already." With B you can say how long ago i.e. "... 3 months ago." 3) A "I lost consciousness." and B "I was lost consciousness." -- First choice, A, is correct. "To be lost", seen in B, can't be used with "conciousness," but can use a prepositional phrase to specify where someone is lost, i.e. "in the city" or "in deep thought", but this phrase won't allow a direct object, "consciousness," because the verb "To be" doesn't take a direct object by itself, however, the verb "to lose" can take a direct object. 4) "In the subconsciousness." and "Into the subconsciousness." --2nd choice describes movement, whereas first choice doesn't necessarily describe movement. 5) "How about playing basketball after school?" or "What about playing basketball after school?" --Either expression is acceptable with the rest of the phrase "playing basketball after school." Hope this helps! Anthony
