error: the Monday.
correction: Monday,
error_type: Determiner Error
error_severity: 3
error_description: ① Determiner Error: In English, the definite article 〈the〉 is not needed before a specific day of the week like 〈Monday〉; therefore, 『the』 should be deleted; ② Punctuation Error: In English, a comma should be added after the introductory time phrase 『On Monday』 at the beginning of the sentence, changing it to 『On Monday,』.

error_sentence: I go to school look my best friend.
correct_sentence: On Monday, I go to school to see my best friend.
error: look
correction: to see
error_type: Verb Choice Error
error_severity: 2
error_description: ① Verb Choice Error: According to the context expressing the meaning of 'seeing someone', the verb 〈look〉 emphasizes the action of 'looking', whereas the context emphasizes the state of 'having seen', so it should be changed to 『see』 to correctly express the intended action; ② Nonfinite Verb Form Error: According to English syntax rules, the verb following 〈go to school〉 should use the infinitive form of a nonfinite verb to express purpose, so it needs to be changed to 『to see』 to correctly express the intended action.

error_sentence: My friend he wear bridge red shirt.
correct_sentence: My friend wears a bright red shirt, because he likes red and he thinks it is very beautiful.
error: he wear bridge
correction: wears a bright
error_type: Word Redundancy Error
error_severity: 5
error_description: ① Word Redundancy Error: The structure of the original sentence 〈My friend he〉 is incorrect because it uses both a noun subject and a pronoun subject; in English, a simple sentence can only have one subject, so only 『My friend』 should be kept; ② Subject-Verb Agreement Error: As indicated by the original sentence, the subject 〈My friend〉 is third-person singular, so the verb 〈wear〉 needs to be changed to the singular form 『wears』 for agreement; ③ Determiner Error: Based on the singular noun 『shirt』 being modified, the indefinite article 『a』 needs to be added before the adjective 『bright』 to comply with English grammar rules; ④ Spelling Error: According to the meaning of the original sentence, the intention here is to describe a "bright red shirt"; thus, the word 〈bridge〉 is a spelling error and should be changed to 『bright』 to indicate a vivid color, fitting the semantics.

error_sentence: My friend he wear bridge red shirt. Beasece he like red
correct_sentence: My friend wears a bright red shirt, because he likes red and he thinks it is very beautiful.
error: . Beasece he like
correction: , because he likes
error_type: Subject-Verb Agreement Error
error_severity: 4
error_description: ① Punctuation Error: The preceding clause “My friend wears a bright red shirt” and the following reason “because he likes red and he thinks it is very beautiful” are closely related and should be expressed in one sentence; therefore, the period 〈.〉 should be changed to a comma 『,』 to ensure sentence coherence; ② Spelling Error: According to spelling rules, the intention here is to express 'because'; thus, 〈Beasece〉 is a spelling error and should be changed to 『because』; ③ Subject-Verb Agreement Error: According to the original sentence, the subject 〈he〉 requires the third-person singular form of the verb, so the verb 〈like〉 needs to be changed to the singular form 『likes』 for agreement.

error_sentence: and he think red is very beautiful.
correct_sentence: My friend wears a bright red shirt because he likes red and he thinks it is very beautiful.
error: think red
correction: thinks it
error_type: Subject-Verb Agreement Error
error_severity: 4
error_description: ① Subject-Verb Agreement Error: As indicated by the original sentence, the subject 〈he〉 is third-person singular, so the verb 〈think〉 needs to be changed to the singular form 『thinks』 for agreement; ② Pronoun Error: From the original sentence 〈Beasece he like red and he think red is very beautiful.〉, the word 〈red〉 appears twice; to avoid repetition, the pronoun 『it』 should be used to replace the second 〈red〉 to clearly indicate the referent.

error_sentence: He wear plua white shoes.
correct_sentence: He wears plain white shoes.
error: wear plua
correction: wears plain
error_type: Subject-Verb Agreement Error
error_severity: 4
error_description: ① Subject-Verb Agreement Error: According to the original sentence, the subject 〈He〉 is third-person singular, so the verb 〈wear〉 needs to be changed to the singular form 『wears』 to maintain subject-verb agreement; ② Spelling Error: According to the original sentence, the intention here is to describe "plain white shoes"; thus, the word 〈plua〉 is a spelling error and should be changed to the correct spelling 『plain』, meaning 'solid-colored', used here with 〈white〉.

error_sentence: l very like too.
correct_sentence: I like them too.
error: l very like
correction: I like them
error_type: Pronoun Error
error_severity: 5
error_description: ① Spelling Error: Based on the intended meaning “I like them”, the personal pronoun “I” should be the subject, but the original sentence uses 〈l〉, which is a spelling error; it needs to be changed to the uppercase form 『I』 to conform to standard usage; ② Adverb Error: According to English grammar rules, 〈very〉 cannot directly modify a verb, so 〈very〉 in the original phrase 〈I very like〉 can be deleted to make the sentence more concise; ③ Pronoun Error: According to lexical rules, when the verb 〈like〉 means 'to be fond of', it is a transitive verb and requires an object; the pronoun 『them』 should be added after it to clearly indicate the object.
