1. It is pain from growing quickly as a teenager.

2. It is pain from growing fast as a teenager.

3. It is pain from growing rapidly as a teenager.

(This is a definition of 'growing pains.' Which one is correct?)

4. You have pimples on your face.
5. You get pimples on your face.

(Are both OK?)

6. Don't sit too close to the TV.
7. Don't sit too near to the TV.
8. Don't sit too by to the TV.
9. Don't sit too nearby to The TV.
(Which one is right?)

1 - 3 are all correct.

4 - 5 are both OK, but don't mean exactly the same thing. #4 means you already have them; #5 means that you might get them or do get them, whether or not you have them now.

6 and 7 are correct; 8 and 9 are incorrect.

For the first three, it helps to set the stage of the statement first.

"As (For) a teenager, growing quickly (fast/rapidly) is a pain."

#7 does not need "to."

"Don't sit too near the TV."

I hope this helps a little more. Thanks for asking.

1. "It is pain from growing quickly as a teenager." - This sentence is grammatically correct and conveys the meaning that the pain is a result of growing rapidly during adolescence.

2. "It is pain from growing fast as a teenager." - This sentence is incorrect because it uses the word "fast" as an adverb instead of "quickly." The correct adverb form is "quickly" in this context.

3. "It is pain from growing rapidly as a teenager." - This sentence is grammatically correct and has the same meaning as the first sentence. It uses the adverb "rapidly" to describe the speed of growth.

So, both the first and third sentences are correct and convey the idea of "growing pains" experienced during adolescence.

Regarding the second question:

4. "You have pimples on your face." - This sentence is grammatically correct and describes the presence of pimples on someone's face.

5. "You get pimples on your face." - This sentence is also grammatically correct. It implies the occurrence of getting pimples on the face, suggesting that it is something that happens to someone.

Both sentences convey the same general idea, but they differ in terms of the tense used. The first sentence states the current presence of pimples, while the second sentence refers to the general occurrence of getting pimples.

For the third question:

Out of the provided options, the correct sentence is:

6. "Don't sit too close to the TV."

This sentence is grammatically correct and conveys the intended meaning. It advises against sitting in close proximity to the TV.

The other options (7, 8, and 9) are incorrect because they use incorrect adverb forms (nearby, by) or do not properly combine "to" and "the" (The TV).
