Error analysis:
error_sentence: She lives in a big village and there is a river near here.
correct_sentence: She lives in a big village and there is a river near there.
error: here
correction: there
error_type: Pronoun Error
error_severity: 3
error_description: Pronoun Error: According to English grammar and context, 〈here〉 is used to refer to a location near the speaker, while this sentence describes a river near her village (relatively far from the speaker), so the demonstrative pronoun 〈there〉 indicating a distant location should be used. 〈here〉 needs to be changed to 『there』.

error_sentence: I always went to the river to fishing.
correct_sentence: I always went to the river to fish.
error: fishing
correction: fish
error_type: Nonfinite Verb Form Error
error_severity: 3
error_description: Nonfinite Verb Form Error: According to English grammar rules, the infinitive structure is “to + base form of the verb”. In the original sentence “to fishing”, 〈fishing〉 is in the present participle form, which does not conform to grammatical rules. 〈to fishing〉 should be changed to 『to fish』 to make the sentence conform to the grammatical rules of infinitives.

error_sentence: That is the funniest thing for me.
correct_sentence: That was the funniest thing for me.
error: is
correction: was
error_type: Verb Tense Error
error_severity: 3
error_description: Verb Tense Error: According to the overall context of the passage, it describes last summer vacation's experience, which belongs to past events and should use the past tense. The original sentence uses the simple present tense 〈is〉, which does not meet the tense consistency requirement. 〈is〉 needs to be changed to the past tense form 『was』 to make the sentence tense consistent with the context of the passage.

error_sentence: There also have a tree house.
correct_sentence: There was also a tree house.
error: also have
correction: was also
error_type: Sentence Structure Error
error_severity: 4
error_description: ① Sentence Structure Error: The basic structure of an existential sentence in English is “There + be”; the original sentence's use of 〈have〉 does not conform to this structural rule. 〈have〉 should be changed to 『was』; ② Subject-Verb Agreement Error: The subject of the sentence “a tree house” is singular, so the be verb should be in singular form. Combined with the sentence context (describing the past), 〈was〉 should be used, changing 〈There also have〉 to 『There was also』 to ensure subject-verb agreement and conform to the existential sentence structure.

error_sentence: We like went to here and do everything that made us happy.
correct_sentence: We liked to go there and do everything that made us happy.
error: like went to here
correction: liked to go there
error_type: Verb Tense Error
error_severity: 3
error_description: ① Verb Tense Error: From the overall context of the sentence, if expressing a past habitual action, the verb 〈like〉 should be in the past tense. 〈like〉 needs to be changed to 〈liked〉; ② Nonfinite Verb Form Error: When a verb follows “like”, the structures “like doing sth.” or “like to do sth.” are commonly used. In the original sentence, the form 〈went〉 is incorrect and should be changed to the infinitive form 〈to go〉, thus changing 〈like went to here〉 to 〈liked to go there〉; ③ Pronoun Error: According to the context, the demonstrative pronoun 〈there〉, referring to a distant place, should be used here, not 〈here〉. 〈here〉 needs to be changed to 『there』.

error_sentence: How a interesting summer vacation!
correct_sentence: What an interesting summer vacation!
error: How a
correction: What an
error_type: Sentence Structure Error
error_severity: 5
error_description: Sentence Structure Error: There are two common structures for exclamatory sentences in English: “How + adjective / adverb + subject + predicate!” and “What + (a/an) + adjective + noun + subject + predicate”. In the original sentence “ How a interesting summer vacation!”, 〈How〉 cannot be directly followed by the indefinite article 〈a〉, and 〈What〉 should be used to modify the noun “summer vacation”. 〈How a〉 should be changed to 『What an』.
