My sweet child 我亲爱的孩子 (taking "sweet child" as to mean "lovely child") Note: No direct translation for "sweet" in this context. Use any other approperiate adjective. however, 我甜蜜的孩子 would sound unnatural to me in this case. I'd give my life for yours 我愿与你替换生命 Note: because one cannot literally "give life", there is no direct translation. hence i opt to use 替换 which is "in place of" + "exchange" I'd lay down my life for you 我愿为你放下生命 Note: in this case, direct metaphoric translation is possible. lest some harm should come to you 不让你受到(任何)伤害 I'd sacrifice my life for you 我愿为你牺牲生命

If you are saying that your friend is coming (here) to study... the most natural way to say it is mother: why is he coming now? you: he is coming to study? 他现在来这里读书。 지금은 그를 와서 공부할거예요. (is my korean correct? I'm learning it now... XD)

还 is largely smilarly to the english "still" or "yet another", and used like a conjuction as "and". usually, when you want to express one or more options/things in a sentence you use "还 something". Note: the other meaning of 还 is as a verb to mean "return", "giving back (something)" 有 is "have" or "to exist" 是 is "to be", "is/are/am.." therefore, 还有 is "still exist (another)...", "and there is another...", "and also..." eg. dogs 还有 cats have four legs. "dogs, and also cats have four legs" eg. he 还是 not here "he still is not here" eg. he STILL hasn't reached AND (still) he is at home! "he 还是 not here, he 还在 home!" "他还没到，他还在家!" In the chinese version, there the AND emphasis is already expressed in 还 Notice that it would be more straight forward to use "dogs 和 cats have four legs". Hence, in colloquial situation, 还有 is used mostly when you start a sentence... then half way you want to add more content or you remember yet another something, then you use 还有. eg. "When you reach home, please remember to eat.. oh, and feed the cat" When you reach home, please remember to eat.. oh, 还有 feed the cat. another standard phrase 还是, as a conjuction, would mean "or" and have the same colloquial function. If right from the start all options for "or" was known, 或 would be used instead. e.g. A or B, please choose == A 或 B, please choose. e.g. so you are thinking of A... or is it B? == so you are thinking of A ... 还是 B?

To add on... 及时 = "just in time", "immediately" eg. He came just in time. 他及时(赶)到。 及早 = "as soon as possible"; "as early as possible" eg. I will come as soon as possible. 我会及早到(达)。 尽快 = "as quickly as [he] could"; "as quickly as possible [for him]" eg. I will come as fast as I can. 我会尽快(赶)到。 nb: the 尽 here gives the nuance that something/somebody is putting in an effort (a lot, completely; tired its best) to execute 到 in the manner of the 快. Hence 尽快 implies a reference to that something/somebody + effort. on the other hand, 及, which means "extreme(ly)" is modifying 时 and 早 to indicate the idea of time. i.e. extremely early, or extremely on time.

it means "like"; "same as"; "smilar to"; ".. such as..." 像他这样的好孩子， 谁不喜欢呢！ [As for] good kids like him/this, who would not like/love? 像洗衣机这种里用电器， 在这里还不普遍 [As for] household appliances like this [type of] washing machine, [they] are not common.
