Thank you very much for your corrections. Here are some more sentences for you to check.

1)The mirror claims to have no preconception since it projects whatever it sees umisted by love or dislike.It reflects a woman who is becoming (growing, getting old). Are they all possible?
2) The most common foot in English poetry is iambic (or the iamb), a two-syllable foot in an unstress-stress pattern.
3)Examples of iambic metre are the words "forgive" and "believe".
4) The mirror can be considered as a symbol of the reflection of human soul, of the passing of time, of the dichotomy between desire and reality.
5)The mirror is personified because it is given human connotations.
6) The candles and the moon are defined as liars because they do not project what the woman really is (or what she is really like?). They project an unfaithful image of the woman.
7) We don't have time to stare at the beauty of nature (nature's beaty) when passing through the wood (woods). The poet reflects upon the meaning of human busy (??) life and complains about it because we have no time to admire the beauty of nature like sheep and cows (better: as sheep and cows do)
8)Poetry is the art of writing poems (not: to write poems).

Read carefully to catch all the changes I made:

2) The most common foot in English poetry is the iamb, a two-syllable foot in an unstress-stress pattern.

3)Examples of iambic metre are the words "forgive" and "believe".

4) The mirror can be considered a symbol of the reflection of the human soul, of the passing of time, of the dichotomy between desire and reality.

5)The mirror is personified because it is given human characteristics.

6) The candles and the moon are defined as liars because they do not project what the woman is really like. They project an unfaithful image of the woman.

7) We don't have time to stare at the beauty of nature when passing through the woods. The poet reflects upon the meaning of the human's busy, everyday life and complains about it because there is no time to admire the beauty of nature as sheep and cows do.

1) The sentences provided are all grammatically correct. However, there is a typo in the second sentence. It should read "It reflects a woman who is becoming (growing, getting old)." instead of "It reflects a woman who is becoming (growing, getting old)."

2) The sentence is grammatically correct, and it accurately states that the most common foot in English poetry is iambic, which consists of two syllables in an unstress-stress pattern.

5) The sentence is grammatically correct, and it explains that the mirror is personified because it is given human characteristics or qualities.

6) The first part of the sentence, "The candles and the moon are defined as liars," is grammatically correct. However, there is a better way to phrase the second part of the sentence.

7) The first part of the sentence, "We don't have time to stare at the beauty of nature," is grammatically correct. However, there are a couple of improvements to make in the second part of the sentence. It should read, "when passing through the woods." instead of "when passing through the wood." Additionally, instead of "the meaning of human busy life," it could be rephrased as "the significance of a busy human life." Lastly, the phrase "like sheep and cows" should be replaced with "as sheep and cows do."

8) The sentence is grammatically correct, and it states that poetry is the art of writing poems. It is important to note that "to write poems" could still be acceptable, but "writing poems" is a more commonly used form.
