error_type: Sentence Structure Error
error_severity: 4
error_description: ① Pronoun Error: This is intended to mean 'his'; according to English writing conventions, 〈he's〉 should be changed to 『his』; ② Sentence Structure Error: The original sentence 〈his family so poor〉 lacks a predicate verb; 『was』 needs to be added after 〈family〉 to form a complete subject-verb structure.

error_sentence: He was very lucky because some nice people help he to go to school.
correct_sentence: He was very lucky because some nice people helped him to go to school.
error: help he
correction: helped him
error_type: Verb Tense Error
error_severity: 4
error_description: ① Verb Tense Error: Judging from the context, the main clause is in the past tense (was), so the verb 〈help〉 in the subordinate clause should also be changed to the past tense form 『helped』; ② Pronoun Error: 〈he〉 is in the object position of the original sentence and needs to be in the objective case 『him』 instead of the nominative case 〈he〉.

error_severity: 3
error_description: Verb Tense Error: The original sentence intends to express 'he wrote more than 160 stories in his life'; the passive voice structure 〈was write〉 does not conform to the active voice expression habit and should directly use the past tense 『wrote』 to indicate a past action.

error_sentence: He was dead in 1875.
correct_sentence: He died in 1875.
error: was dead
correction: died
error_type: Verb Choice Error
error_severity: 3
error_description: Verb Choice Error: In the original sentence, 〈was dead〉 expresses a state rather than an action; judging from the context, it should be changed to 『died』 to express the action 'passed away', therefore 〈was dead〉 is modified to 『died』.

error_sentence: we are still influenced by his stories.

correct_sentence: We are still influenced by his stories.

correction: We
error_type: Case Error
