1. He took a flight to his hometown.

(What does 'flight' mean here? Does 'flight' mean 'airplane'?)
It means "a trip on an airplane."

2. Your childish games don't amuse me one bit.
(What other expressions can we use instead of 'one bit'?)
You can also use "at all."

3. Jane can dance with skill.
4. Jane can dance skillfully.
(Are both the same?)
Yes, they mean the same thing.

5. He slipped into the room.
6. Figure skating requires flexibility.
7. Neither one of these computers is working.
(Are the three sentences grammatical? I appreciate your help. Have a great weekend. See you later.)
Yes, all are correct. Very nice!

1. In the sentence, "flight" refers to a journey or trip taken by air, typically on an airplane. So yes, in this context, "flight" means "airplane" or the act of traveling in an airplane.

2. Instead of the expression "one bit," you can use other phrases such as "at all," "in the slightest," "in the least," or "in the smallest degree." These phrases convey the same meaning of not being amused even in the slightest.

3. Yes, both sentences convey the same meaning. In sentence 3, "with skill" functions as an adverbial phrase modifying the verb "dance." In sentence 4, "skillfully" is an adverb derived from the adjective "skillful" and also modifies the verb "dance." Both sentences emphasize Jane's ability to dance with proficiency.

5. "He slipped into the room" is a grammatically correct sentence. It means that he entered the room quietly or unnoticed.

6. "Figure skating requires flexibility" is grammatically correct. It states that flexibility is a necessary skill or attribute for figure skating.

7. "Neither one of these computers is working" is grammatically correct. It identifies that not a single one out of the two computers is functioning properly.

I hope this helps! If you have any more questions, feel free to ask. Have a great weekend, too! See you later!
