error_description: Spelling Error: According to English spelling conventions, the correct spelling for the word 'present' is 'present', so there is a spelling error here. The incorrect spelling 〈presen〉 needs to be changed to 『present』 to comply with English spelling rules.
error_sentence: At the present , there were no buildings in the city.
correct_sentence: In the past, there were no buildings in the city.
error: At the present
correction: In the past
error_type: Noun Error
error_severity: 4
error_description: ① Preposition Error: According to the original sentence's meaning, the intention is to express 'in the past', using the fixed phrase 'in the past' as an adverbial of time to describe a past state. Therefore, the preposition in 〈At the present〉 needs to be changed to 『In』 to form the fixed phrase 'In the past' to match the original meaning; ② Noun Error: According to the original sentence's meaning, the intention is to express 'in the past', using the fixed phrase 'in the past' as an adverbial of time to describe a past state. Therefore, the time noun 〈present〉 in 〈At the present〉 needs to be changed to 『past』 to form the fixed phrase 'In the past' to match the original meaning.
error_sentence: With the development of social, there are more and more buildings were built.
correct_sentence: With the development of society, more and more buildings were built.
error: social, there are
correction: society,
error_type: Word Redundancy Error
error_severity: 4
error_description: ① PoS Confusion Error: According to the original sentence's meaning, the intention is to express 'the development of society', which requires the noun form of the word 'society' after the preposition 〈of〉 to form a possessive structure. Therefore, the adjective 〈social〉 needs to be changed to the noun 『society』 to match the original meaning; ② Word Redundancy Error: The original sentence's there-be structure 〈there are...were built〉 contains a double predicate structure. Expressing 'more and more buildings were built' here does not require the existential sentence pattern. It is necessary to delete the redundant 〈there are〉 and retain the past simple passive voice of the predicate verb 『were built』 to comply with grammatical rules and the original meaning.
