error_type: Determiner Error
error_severity: 2
error_description: Determiner Error: According to English article usage rules, when expressing a general concept rather than a specific one, the definite article is usually not used before plural nouns. In the original sentence, 〈the flowers〉 in 〈buy the flowers〉 does not refer to specific flowers, but rather to the general act of buying flowers, thus 〈the〉 is redundant. Deleting 〈the〉 makes the sentence conform to English expression habits and maintains the non-specific use of the plural noun form.

error_sentence: I sent them to my mum and I did the housework.
correct_sentence: I sent them to my mum and did the housework.
error: I
error_type: Word Redundancy Error
error_severity: 4
error_description: Word Redundancy Error: In the original sentence “and I did the housework”, because the coordinating conjunction 〈and〉 connects “sent them” and “did the housework” which share the same subject, the second 〈I〉 is redundant. According to English expression habits, deleting the redundant 〈I〉 can make the sentence more concise and fluent, avoiding repetition.

error_sentence: She also likes the flowers I bought for her.
correct_sentence: She also liked the flowers I bought for her.
error: likes
correction: liked
error_type: Verb Tense Error
error_severity: 3
error_description: Verb Tense Error: According to English grammar rules, when narrating a series of events that occurred in the past, the tense should remain consistent. In the original sentence, “bought” is in the past tense, indicating that the event happened in the past, while 〈likes〉 is in the simple present tense, which is inconsistent with the context. Changing 〈likes〉 to the past tense 『liked』 makes the sentence tense consistent and conforms to the context of narrating past events.

correct_sentence: In the afternoon, I went to the market to buy groceries.

error_type: Determiner Error
error_severity: 2
error_description: Determiner Error: According to English grammar rules, when 〈market〉 is used as a countable noun and refers to a specific market, it needs to be modified by a determiner. In the original sentence “went to market”, according to the context, it refers to going to a specific market, and it lacks a determiner. 〈the〉 should be added to form 〈went to the market〉, which conforms to English article usage rules and makes the expression accurate and clear.

error_sentence: I cooked a delicious meal in the night.
correct_sentence: I cooked a delicious meal at night.
error: in the
correction: at
error_type: Preposition Error
error_severity: 2
error_description: Preposition Error: According to the idiomatic usage of English time expressions, “在晚上” should be expressed as “at night”. In the original sentence, 〈in the night〉 does not conform to English idiomatic expression and is a preposition usage error. 〈in the〉 should be changed to 『at』 to form “at night”, making the sentence expression conform to English grammar rules and habits.

error_sentence: She was happy for today.
correct_sentence: She was happy today.
error: for
error_type: Preposition Error
error_severity: 2
error_description: Preposition Error: According to English grammar rules, a preposition is usually not needed before the time adverb 〈today〉. In the original sentence “happy for today”, 〈for〉 is redundant and does not conform to English grammar rules and expression habits. Deleting 〈for〉 and using 『happy today』 directly makes the sentence expression concise, idiomatic, and conform to English grammar requirements.

error_sentence: I am happy because of my mum's happiness.
correct_sentence: I was happy because of my mum's happiness.
error: am
correction: was

error_description: Verb Tense Error: According to English grammar rules, when narrating events that occurred in the past, the tense should remain consistent.

Changing 〈am〉 to the past tense 『was』 makes the sentence tense consistent and meets the requirements for narrating past events.
