error_type: Word Redundancy Error
error_severity: 3
error_description: Word Redundancy Error: According to English grammar rules, "a lot of" can only modify nouns; when modifying the adjective 〈different〉, the adverb phrase "a lot" should be used instead of the noun phrase "a lot of", therefore, there is a word redundancy error here. The redundant preposition 〈of〉 needs to be deleted to comply with English grammar rules.

error_sentence: These years, my living environment is a lot of different which will suprise you.
correct_sentence: These years, my living environment is a lot different which will surprise you.
error: suprise
correction: surprise
error_type: Spelling Error
error_severity: 2
error_description: Spelling Error: According to English spelling conventions, the correct spelling for the word meaning "to cause surprise" is "surprise". The incorrect spelling 〈suprise〉 needs to be changed to 『surprise』 to conform to spelling conventions and the original sentence meaning.

error_sentence: In years ago, there weren't any buildings in this place, only we have big fields , some bushes.
correct_sentence: Years ago, there weren't any buildings in this place, and we only had big fields and some bushes.
error: In years
correction: Years
error_type: Word Redundancy Error
error_severity: 3
error_description: Word Redundancy Error: According to English expression habits, the phrase "years ago" means "many years before" and already contains the concept of time; it can directly function as a time adverbial in the sentence without needing the additional preposition "in". Therefore, there is a word redundancy error here. The redundant preposition 〈In〉 is deleted to conform to English expression habits.

error_sentence: In years ago, there weren't any buildings in this place, only we have big fields , some bushes.
correct_sentence: Years ago, there weren't any buildings in this place, and we only had big fields and some bushes.

error_type: Word Order Error
error_severity: 5
error_description: ① Conjunction Error: According to English syntax rules and the original sentence meaning, the original clauses 〈 there weren't any buildings in this place〉 and 〈only we have...〉 are two parallel clauses within the same compound sentence, and there is a close sequential relationship in meaning, so they need to be connected by a comma and a conjunction. The coordinating conjunction 『and』 needs to be added before the parallel clause 〈only we have...〉 to comply with English syntax rules and ensure smooth meaning connection; ② Word Order Error: According to the original sentence meaning, the intention is to express "we only had...", the adverb "only" needs to be placed after the subject 〈we〉 to modify the predicate verb "have", therefore 〈only we〉 needs to be changed to 『we only』 to match the original meaning; ③ Verb Tense Error: According to the context, the actions and events occurred in the past. The present tense verb 〈have〉 should be changed to the past tense 『had』 to match the context's tense.

error_sentence: In years ago, there weren't any buildings in this place, only we have big fields , some bushes.

error_type: Conjunction Error
error_severity: 3
error_description: Conjunction Error: According to English syntax rules, the original phrases 〈big fields〉 and 〈some bushes〉 are the only two parallel sentence components after 〈and we only had〉, and they need to be connected by a coordinating conjunction. Therefore, there is a conjunction error here. The comma 〈 ,〉 needs to be changed to the coordinating conjunction 『and』 to comply with English syntax rules and ensure smooth meaning connection.

error_sentence: It is beautiful scenery , but isn't good for people living.
correct_sentence: It was a beautiful scenery, but it wasn't good for people living there.
error: is
correction: was a
error_type: Verb Tense Error
error_severity: 5
error_description: ① Verb Tense Error: According to the context, the actions and events occurred in the past, so the present tense 〈is〉 should be changed to the past tense 『was』 to match the context's tense; ② Determiner Error: According to English grammar rules, the singular countable noun 〈scenery〉 requires a corresponding determiner before it; here, the indefinite article 『a』 needs to be added to express "a beautiful scenery" to fit the original context and grammar rules.

error_sentence: It is beautiful scenery , but isn't good for people living.
correct_sentence: It was a beautiful scenery, but it wasn't good for people living there.
error: is
correction: it was
error_type: Verb Tense Error
error_severity: 5
error_description: ① Pronoun Error: According to English syntax rules, the sentence lacks a subject, resulting in an incomplete sentence structure; 『it』 needs to be added after 〈but〉 as a formal subject to make the sentence structure complete; ② Verb Tense Error: According to the context, the actions and events occurred in the past, so the present tense 〈is〉 should be changed to the past tense 『was』 to form the correct negative auxiliary contraction with the following "n't" to match the context's tense.

error_sentence: It is beautiful scenery , but isn't good for people living.
correct_sentence: It was a beautiful scenery, but it wasn't good for people living there.
correction: there
error_type: Preposition Error
error_severity: 2
error_description: Preposition Error: According to the original sentence meaning, the intention is to express "that environment was not suitable for people living". The gerund 〈living〉 needs an adverb of place following it; therefore, 『there』 needs to be added to make the sentence structure complete and conform to the original meaning.

error_sentence: But now, it is different, there are so many building, block of flats.
correct_sentence: But now, it is different. There are so many buildings and blocks of flats.
error: , there
correction: . There
error_type: Punctuation Error
error_severity: 2
error_description: Punctuation Error: According to English syntax rules, the clauses 〈it is different〉 and 〈there are so many building〉 contain independent subject-verb structures and belong to two different idea groups, thus they need to be separate sentences, separated by a period. 〈, there〉 should be changed to 『. There』 to comply with English syntax rules.

error_sentence: But now, it is different, there are so many building, block of flats.
correct_sentence: There are so many buildings and blocks of flats.
error: building, block
correction: buildings and blocks
error_type: Conjunction Error
error_severity: 5
error_description: ① Noun Number Error: According to the preceding determiner 〈many〉, the following countable nouns need to be in plural form. Therefore, 〈building〉 and 〈block〉 need to be changed to the plural forms 『buildings』 and 『blocks』 to match the context and grammar rules; ② Conjunction Error: According to English syntax rules, the original phrases 〈buildings〉 and 〈blocks of flats〉 are the only two parallel sentence components after 〈there are so many〉, and they need to be connected by a coordinating conjunction. Therefore, the comma 〈 ,〉 needs to be changed to the coordinating conjunction 『and』 to comply with English syntax rules and ensure smooth meaning connection.
