1. He can not only swim but also dance.

(Are they all grammatical? Which one is commonly used?)
4. He is not only strong but also fast.
5. He is fast as well as strong.
(Are they the same, right?)

(Are the three all grammatical? Which one is commonly used?)
1, 2, and 3 are grammatical, but 2 is most common.
The others are correct.
1. He can not only swim but also dance.
2. He not only can swim but also can dance.
3. Not only he can swim but also he can dance.
Out of these three sentences, the most commonly used and grammatically correct one is sentence 1: "He can not only swim but also dance."
In this sentence, the word "not" is positioned correctly, and there is no repetition of auxiliary verbs. The structure "not only... but also" is used correctly to emphasize that the person can do both activities.
4. He is not only strong but also fast.
5. He is fast as well as strong.
These two sentences convey a similar meaning but with a slight difference in emphasis. Sentence 4 emphasizes that he possesses both qualities, while sentence 5 focuses more on the fact that he is fast in addition to being strong. Both sentences are grammatically correct and can be used interchangeably.
6. He speaks not only English but also Chinese.
7. He not only speaks English but also Chinese.
8. He not only speaks English but also speaks Chinese.
All three of these sentences are grammatically correct. However, sentence 6 is the most commonly used and preferred construction: "He speaks not only English but also Chinese." This sentence is more concise and flows better. Sentences 7 and 8 are also grammatically correct but may sound slightly less natural in comparison.
