correction: ,
error_type: Punctuation Error
error_severity: 2
error_description: Punctuation Error: According to English writing conventions, a comma is needed between the greeting 〈Hello〉 and the personal introduction 〈I'm Amy〉. In the original sentence, they are directly connected, which is incorrect. A comma 『,』 should be added after 〈Hello〉, changing the sentence to 『Hello, I'm Amy.』, to make the expression conform to English letter format conventions.

correct_sentence: Hello, I'm Amy. You should visit the London Eye.
error: you
correction: . You
error_type: Punctuation Error
error_severity: 2
error_description: Punctuation Error: According to English grammar rules, 〈Hello, I'm Amy〉 and 〈you should visit the London Eye〉 are two independent sentences, each with a complete subject-verb structure. The original sentence lacks a period to separate them, causing a run-on sentence. A period 『.』 should be added after 〈Amy〉 to correctly separate the two sentences, thus it should be changed to 『. You』, making the sentence writing conform to conventions.
error_sentence: Hello I'm Amy you should visit the London Eye you should take a plane
correct_sentence: You should visit the London Eye.
error: you should take a plane

error_type: Sentence Redundancy Error
error_severity: 4
error_description: ① Sentence Redundancy Error: According to the context, the original sentence, while not yet finished elaborating on the suggestion “you should visit the London Eye”, abruptly inserts “you should take a plane”, breaking the semantic logic. The redundant part 〈you should take a plane〉 should be deleted to make the expression more focused; ② Punctuation Error: In the original sentence, 〈you should visit the London Eye〉 and 〈you should take a plane〉 are two independent parts, each with a complete structure. However, the sentence lacks punctuation to separate them, which does not conform to English grammar rules. A period 『.』 should be added after 〈you should visit the London Eye〉 to reasonably divide the sentence and make the sentence structure complete.
error_sentence: It's very long So you should take a plane
correct_sentence: It's very far, so you should take a plane.
error: long So
correction: far, so
error_type: Adjective Error
error_severity: 3
error_description: ① Adjective Error: According to English expression habits, the adjective 〈far〉 should be used to describe distance, while 〈long〉 is usually used to describe length. In the original sentence, using 〈long〉 to describe distance is inappropriate; 〈long〉 should be changed to 『far』 to make the expression semantically appropriate; ② Punctuation Error: According to English grammar rules, when the conjunction 〈so〉 connects two clauses, it is usually preceded by a comma. The original sentence lacks a comma before 〈So〉, leading to an ungrammatical sentence structure. A comma should be added before 〈So〉, changing 〈long So〉 to 『far, so』, to make the sentence conform to grammatical rules.
error_sentence: It's very far The museum is very intereing
correct_sentence: It's very far, so you should take a plane.
error: It's very far
correction: .
error_type: Sentence Redundancy Error
error_severity: 4
error_description: Punctuation Error: In the original sentence, “It’s very far” and “The museum is very intereing” are two independent sentences directly connected, causing a run-on sentence error. According to the contextual logic, no conjunction is needed here; instead, the previous statement should be concluded. Therefore, a period should be added after “It’s very far” for separation.
error_sentence: It's very far The museum is very intereing So you should go to the museum
correct_sentence: The museum is very interesting, so you should go to the museum.
error: intereing So
correction: interesting, so
error_type: Punctuation Error
error_severity: 2
error_description: ① Spelling Error: According to the sentence meaning, it is clear that the intention is to express “interesting”, but 〈intereing〉 is a misspelling of 〈interesting〉. To make the expression correct, 〈intereing〉 needs to be changed to 『interesting』; ② Punctuation Error: According to English grammar rules, when the conjunction 〈so〉 connects two clauses, it should be preceded by a comma. The original sentence lacks a comma before 〈So〉, which does not conform to grammatical norms. A comma needs to be added before 〈So〉, changing 〈intereing So〉 to 『interesting, so』.
error_sentence: So you should go to the museum
correct_sentence: The museum is very interesting, so you should go to the museum.
correction: .
error_type: Punctuation Error
error_severity: 2
error_description: Punctuation Error: According to English writing conventions, a complete sentence needs to end with a period. The original sentence 〈so you should go to the museum〉, as a complete sentence, lacks a period at the end. A period 『.』 should be added at the end of the sentence to make it conform to English writing conventions.
