Error analysis:
error_sentence: Nowdays,after-school activities are becoming more and more popular in high schools.

correct_sentence: Nowadays, after-school activities are becoming more and more popular in high schools.

error: Nowdays
correction: Nowadays
error_type: Spelling Error
error_severity: 2
error_description: Spelling Error: According to the sentence meaning, it intends to express 'nowadays'; 〈Nowdays〉 is a misspelling of 『Nowadays』, so 〈Nowdays〉 needs to be changed to 『Nowadays』 to make the sentence coherent.
error_sentence: For example,I like dance very much,so I take part in the dance club.
correct_sentence: For example, I like dancing very much, so I take part in the dance club.
error: dance
correction: dancing
error_type: Nonfinite Verb Form Error
error_severity: 3
error_description: ① Nonfinite Verb Form Error: According to English grammar rules, the verb 〈like〉 should be followed by a gerund to express a continuous action, conforming to the fixed phrase 'like doing'. The original word 〈dance〉 is in its base form, which is a nonfinite verb form error; 〈dance〉 needs to be changed to 『dancing』 to comply with grammatical rules.
error_sentence: And at the same time I can also make some new friends who have the same interest with me.
correct_sentence: And at the same time, I can also make some new friends who have the same interests as me.
correction: ,
error_type: Punctuation Error
error_severity: 2
error_description: Punctuation Error: According to English writing conventions, when 〈And at the same time〉 is used as an introductory adverbial phrase, it should be separated from the main clause by a comma. The original sentence omits the comma; a 『,』 should be added after 〈And at the same time〉 to comply with English punctuation rules and clearly separate the adverbial phrase of time from the main clause structure.
error_sentence: And at the same time I can also make some new friends who have the same interest with me.
correct_sentence: And at the same time, I can also make some new friends who have the same interests as me.

error_type: Noun Number Error
error_severity: 3
error_description: ① Noun Number Error: According to the sentence meaning, 〈interest〉 refers to multiple common interests and needs to be in the plural form; 〈interest〉 should be changed to 『interests』; ② Preposition Error: According to English expression habits, 'the same...as' is a fixed phrase meaning 'the same as...'; the original word 〈with〉 does not conform to this collocation rule and should be changed to 『as』.
error_sentence: We always watch some interesting English movies together in the free time.
correct_sentence: We always watch some interesting English movies together in our free time.
error: the
correction: our
error_type: Determiner Error
error_severity: 3
error_description: Determiner Error: According to the sentence meaning, the definite article 〈the〉 in 〈the free time〉 is used inappropriately as it fails to clearly indicate the possessive relationship with the subject 〈We〉. 『our』 is needed to clearly indicate 'our' free time; the original 〈the〉 is a determiner error and should be changed to 『our』 to ensure clarity and accuracy of meaning.
error_sentence: Thanks to that,I improve my hearing English and get better grades in the English exams.

correct_sentence: Thanks to that, I improve my English listening skills and get better grades in the English exams.

error_severity: 3

error: activites
correction: activities
error_type: Spelling Error

correct_sentence: First, you'd better choose the activities which interest you and suit you.
error: you'd

error_type: Space Error
error_severity: 1

error_sentence: Second,make sure that you can really benefit a lot from that.

correct_sentence: Second, make sure that you can really benefit a lot from them.

error: that
correction: them
error_type: Pronoun Error
error_severity: 3
error_description: Pronoun Error: According to the context, the pronoun 〈that〉 has an unclear reference; the preceding noun 〈activities〉 is plural, so 『them』 is needed to refer back to the plural noun 〈activities〉, maintaining pronoun-antecedent agreement. Therefore, 〈that〉 should be changed to 『them』.
