1. How often do you read the newspaper?

- Sometimes.
- I often read it.
- I read the newspaper from time to time.
- Three times a week.
- I never read it.
(Are the answers all acceptable? Do you have some more common answers?)

2. Don't be worried about that.
2-1. Don't worry about that.
2-2. Don't be concerned about that.
(Are the three the same?)

All of the newspaper sentences are fine.

I read parts of the newspaper everyday.

All of the #2 sentences are the same.

If #1 is a survey question, you might want to be more specific in your alternatives:

Daily
5-6 times a week
2-4 times a week
weekly
less than weekly
never

"Sometimes," "Often" and "time to time" are very vague terms.

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

1. All of the answers provided for the frequency of reading the newspaper are acceptable, as they indicate different levels of regularity. Some more common answers could be "Every day" or "Once a week."

2. The three phrases "Don't be worried about that," "Don't worry about that," and "Don't be concerned about that" convey a similar message, but there are slight differences in their nuances.

- "Don't be worried about that" suggests that there is no need for concern or anxiety.
- "Don't worry about that" carries a similar meaning, reassuring the person not to be troubled or anxious.
- "Don't be concerned about that" emphasizes that there is no need for them to be worried or have any particular attention on the matter.

Overall, the three phrases convey the message that the person should not be anxious or troubled about the particular issue.
