Q: <span class="dictionary_keyword">not</span> longer を使った例文を教えて下さい。
A: "Not longer" and "no longer" have different uses in English. "Not Longer" would be used to say "This shoes is <span class="dictionary_keyword">not</span> longer than that shoe," used for comparing two things. "No longer" would be used for example when someone is fired from their job "The employee is no longer working with the company" it could also be used to talk about time, "The meeting will be no longer than 45 minutes." In this context, "no longer than" equals the maximum amount of something.

A: Its commonly used with "don't know," such as "I don't know whether or <span class="dictionary_keyword">not</span> I should go" or "She doesn't know whether or <span class="dictionary_keyword">not</span> she got accepted."
Other example:
I will finish the movie, whether or <span class="dictionary_keyword">not</span> I like it.

also, people often put "<span class="dictionary_keyword">not</span>" after the verb or omit it altogether and use "whether" like "if." For example: "I don't know whether I should go (or <span class="dictionary_keyword">not</span>)" or "She doesn't know whether she got accepted (or <span class="dictionary_keyword">not</span>)"

Q: I'm <span class="dictionary_keyword">not</span> と I ain't はどう違いますか?
A: Like what was answered above, "ain't" is a slang and considered quite improper. You don't hear it a lot, especially with common situations. "Am <span class="dictionary_keyword">not</span>" is almost always used, unless someone tends to use slang a lot.
Q: <span class="dictionary_keyword">not</span> really と <span class="dictionary_keyword">not</span> much はどう違いますか?
A: They can be interchangeable, sometimes, though with slightly different meaning (ちょっと意味が違います):
A: Do you have time to talk?
B: Not really. (いや、ちょっとないんですよ)
B: Not much. (あんまりないけど【ちょっとある】)

A: Do you have any money I could borrow?
B: Not really. (あ、今はちょっとむりですよ)
B: Not much. (あんまりない【でも少しならある】)

Sometimes they are <span class="dictionary_keyword">not</span> interchangeable:
A: How much milk is left?
B: Not really. (✕ あってない)
B: Not much. (あと少しだけ)

really = 本当に、実に
<span class="dictionary_keyword">not</span> really = そう~~でもない
It's really hot today = 今日実に暑いですね。
It's <span class="dictionary_keyword">not</span> really hot today = そんなに暑くない。

much = ~が沢山

Placement in the sentence makes ALL the difference!
I really don't have time! - 本当に時間がないんだよ。
I don't really have time. - あんまり時間がないんですけど。
Q: <span class="dictionary_keyword">not</span>....any more と <span class="dictionary_keyword">not</span>....any longer はどう違いますか?
A: "If you are satisfied with my answer", or
"If you are already satisfied with my answer"
are correct.
"then I won't write any more" means I won't write any more words
"then I won't write any longer" means I won't take more time to keep answering
Q: <span class="dictionary_keyword">not</span> と no はどう違いますか?
A: "Not" negates a verb (i.e. "I do <span class="dictionary_keyword">not</span> want").

"No" negates a noun (i.e. "No smoking")
Q: unless と <span class="dictionary_keyword">not</span> unless はどう違いますか?
A: Unless is used to describe something that will happen if something else doesn't happen. For example, "I will walk to school unless it rains," which means that I will walk to school if it does <span class="dictionary_keyword">not</span> rain.

"Not unless" is a little more situational. You would probably only use it if asked a yes/no question, to which the answer is "no" with an exception. For example, "are you going tomorrow?" "Not unless there's food." In this case, the person is saying he will only go if there is food. Outside of such a situation, you probably won't find "<span class="dictionary_keyword">not</span> unless."

Q: why "From" and <span class="dictionary_keyword">not</span> "In" or "on"?
A: pero, actually, the information is <span class="dictionary_keyword">not</span> IN / INSIDE the sheet of paper ... because there is no INSIDE or OUTSIDE of a piece of a paper. However, the information would be IN / INSIDE a book.

Basically, if there is an opening for something, use IN. If it's a flat surface, use ON.

So, the only way you could say "the information is inside this sheet of paper." is if the paper was folded &amp; you have to actually open it to get the information.
