58. My parents let their son listen to music.

- In this sentence, "allow" and "let" are both verbs that convey permission. "Allow" typically conveys a formal sense of permission, whereas "let" is more informal. In the original sentence, "My parents allow their son to listen to music," the structure is to indicate that the parents give their son permission to engage in the activity of listening to music. By using "let," this idea is preserved, making it "My parents let their son listen to music."

57. My parents don't allow me to use the mobile phone.

- Here, the wording "I am not allowed" indicates a prohibition, implying that the speaker's parents do not permit them to use the mobile phone. To rephrase it from the perspective of the parents, we say "My parents don't allow me to use the mobile phone," where "don't allow" directly expresses the restriction imposed by the parents on the speaker regarding the use of the mobile phone.
