The problem is that neither sentence is an example of grammatically correct English. The sentences would make more sense if you replace "until" with "after." If you make this change, there is still not much difference in meaning. Neither sentence implies that the construction actually started.

I am not sure that english has words to define different abilities to memorize. Photographic memory describes a person who remembers everything they read. Other than that, the normal comparisons apply. It is said that some people have pictorial memories (that is they can remember what they see, or a diagram). Some people have good memories of music and can remember everything about a song or any other piece of music. If you are asking how to improve memory, you can look at various published methods. One is to associate facts with objects in your home. Another is to make a diagram that relates facts to a central theme. It is possible that people can improve their ability to memorize facts by associating them with things they find easy to remember. Different people may use different methods. In India, many test questions ask for remembered facts. Remembering facts under stress is also a skill that can be learned. How people learn is a topic for another time. A comment on your English. Your sentences appear to be a direct translation from Hindi. You could improve your grammar by reviewing some of the basics of English word order. You could also try to write shorter sentences. If you are unsure of spelling, you can use google translate to help.

Your question was "can you say me what's meaning of.." It would be better to ask: Can you tell me what is the meaning of..." In America, we like to see an article before every noun. There are exceptions, but few of them.

I would say the author is being poetic. green gives us a variety of images of plentiful plants, bushes or trees in a tropical forest or jungle. Such a place may be underdeveloped or undeveloped in a third world country. Green also has overtones of saving the environment. contrasted with tubercular, the word green might imply healthy. Tuberculosis is a lung disease that is highly contagious. It is associated with physical weakness and early death. Is the author saying that it is better to be a poor person in Haiti than to suffer Russian winters? Could be.

"way to play along, Mr. Smooth" indicates that the speaker is being ironic. He is saying the opposite of what he means. My translation might be "you are being uncooperative and making a bad impression"

there are really three words: to use (verb as in "I use my credit card") use (noun as in "What use is paper money?" or "that word is no longer in use" or "it has fallen out of use" ) usage (noun as in "the usages of the last 50 years") Use and usage are almost always interchangable. "Use" is the more common, conversational choice. "Usage" implies a more scholarly or learned point of view. The dictionary disagrees and says "usage" is the act, manner or amount of "using"

Two comments. First, it is best to write or say "What does __________ mean?" Second, I suspect you saw the phrase "Not at all." This is a polite response to "thank you." meaning "it was no trouble"

No. "I got cured from...." is not either frequent or good use in the US. We can say "I am over my cold (the chicken pox, typhoid, etc.).
