1. Watching a variety of shows might expose us to things we might otherwise never come across in our own lives.

(What is the meaning of 'come across' here? Some other similar expressions, please?)

2. We can bond over shared views by watching some TV shows together. (Is this sentence correct? Can we use 'over'? What about 'about' or 'on'?)

3. There might be a certain benefits to watching television.

4. There might be a certain benefits in watching television.

5.There might be a certain benefits of watching television.

6. There might be a certain benefits on/about watching television.
(Which preposition do we have to use among Sentence 3-6?)

1. "come across" could mean things we

-- see
-- hear
-- experience
-- etc.

2. I think "over" works well here. Another might be "because of" or possibly "by means of."

In 3-6, you need "benefit" (singular form) -- or omit "a" if you want that word to be plural. And I think the best preposition there is "to" with "in" coming in a close second! I wouldn't use the others.

1. In the sentence "Watching a variety of shows might expose us to things we might otherwise never come across in our own lives," the phrase "come across" means encountering or finding something by chance or unexpectedly. It suggests discovering something that we would not normally encounter in our daily lives. Some similar expressions to "come across" that can be used in this context are "stumble upon," "encounter," "discover," or "find."

2. The sentence "We can bond over shared views by watching some TV shows together" is correct. In this sentence, the word "over" is used to indicate that the bond or connection is created by or based on the shared views. Alternatively, you could also use the prepositions "about" or "on" in this context. So, the sentence can be rephrased as "We can bond about shared views by watching some TV shows together" or "We can bond on shared views by watching some TV shows together."

3-6. The correct preposition to use among Sentence 3-6 is "for." Therefore, Sentence 3 is correct: "There might be certain benefits to watching television." The preposition "to" is used to show the purpose or intention of watching television in order to achieve those benefits. The correct sentence should be: "There might be certain benefits to watching television."
