{Thank you for your kindness. Your correction is of great help. Have a great weekend!}
Would you check the answers above? Are they grammatical? Correct any errors, please.

All are correct, except #9. When the noun starts with a vowel, we use "an" instead of "a". It's easier to pronounce. So, instead of "a oriental clinic", it should be "an oriental clinic". The word "herb" presents a different problem when using "a" and "an". The "h" in "herb" is often silent. It can be pronounced as "herb" or "erb"; both are correct. Usually, no matter how it is pronounced, nouns beginning with the letter "h" would be "an herb", for example, since the "h" sound is very soft, silent or not.

There are exceptions. If the "h" is the dominant sound, or pronounced in a "hard" way, "a" is acceptable. "A hound dog", for example, or "a hurricane" is acceptable, but "an herb" is more acceptable in this instance.

English is a strange language! Just note that the difference between "a noun" and "an object" means nothing at all, except in how easy it is to say it aloud.

Most of the sentences are grammatically correct, with a few minor changes in punctuation and sentence structure. However, there are a couple of errors that need to be corrected:

7. Instead of "sea weeds," it should be "seaweed" (non-count noun).
8. Instead of "go to see a doctor," it should be "go see a doctor" (omit "to").
9. Instead of "a herb doctor," it should be "an herb doctor" (use "an" before words starting with a vowel sound).

Here are the corrected sentences:

1. Why don't you buy a jump rope and jump rope from time to time?
2. Why don't you play basketball with others in the gym?
3. Why don't you do gymnastics on a regular basis?
