error_type: Space Error
error_severity: 3
error_description: ① Space Error: According to English writing conventions, spaces are needed between words in a sentence to avoid run-on elements. Therefore, a space needs to be added between the number 〈7〉 and the be-verb 〈is〉, changing 『is7』 to 『is 7』 to conform to writing conventions; ② Punctuation Error: According to English syntactic rules, an independent sentence requires a punctuation mark at the end to indicate its conclusion, so a period is missing at the end of the original sentence. A 『.』 needs to be added after 〈o'clock〉 to mark the end of the sentence in accordance with English syntactic rules.

error_type: Punctuation Error
error_severity: 4
error_description: ① Punctuation Error: According to English syntactic rules, a period is missing between the two independent sentences “My brother...” and “My sister...”; a 『.』 needs to be added after 〈games〉 to avoid a run-on sentence; ② Spelling Error: According to English spelling rules, the correct spellings for “电脑” (computer) and “姐妹” (sister) are “computer” and “sister”. Therefore, the misspelled 〈comeputer〉 should be changed to 『computer』, and 〈sisyer〉 should be changed to 『sister』 to conform to spelling rules.

error_type: Preposition Error
error_severity: 5
error_description: ① Preposition Error: According to English grammar rules, the intransitive verb “listen” requires the preposition “to” to form a transitive phrasal verb. Therefore, the preposition 『to』 needs to be added after 〈listening〉 to conform to the original meaning and grammar rules; ② Determiner Error: According to English grammar rules, when a singular countable noun refers to something specific, it requires a definite article before it. Therefore, the definite article 『the』 needs to be added before 〈tadio〉 to indicate specificity, conforming to the original meaning and English grammar rules; ③ Spelling Error: According to the original meaning, the intention is to express “listen to the radio”; the correct spelling for the word “广播” (radio) is “radio”. Therefore, the misspelled 〈tadio〉 should be changed to 『radio』 to conform to spelling rules.

Here, the subjective pronoun 〈I〉 needs to be changed to the objective pronoun 『me』 to conform to grammar rules; ③ Punctuation Error: According to English syntactic rules, an independent sentence requires a punctuation mark at the end to indicate its conclusion, so a period is missing at the end of the original sentence. A 『.』 needs to be added after 〈me〉 to mark the end of the sentence in accordance with English syntactic rules.
