error_type: Verb Choice Error
error_severity: 3
error_description: ① Verb Choice Error: The sentence lacks a predicate verb; 『are』 needs to be added after the subject 〈Linda and her family〉 to form a subject-complement structure and ensure sentence completeness; ② Preposition Error: According to English collocation rules, the preposition 〈in〉 usually indicates inclusion 'inside/within', while 『at』 should be used for specific locations; therefore, 〈in〉 is changed to 『at』 to conform to standard usage for location prepositions.

error_type: Determiner Error
error_severity: 2
error_description: Determiner Error: According to English noun possessive rules, the possessive structure 〈Linda's〉 already has a determining function; adding the definite article 〈the〉 causes redundancy. Therefore, the redundant 『The』 is deleted, keeping 『Linda's』 to ensure the expression is both grammatically correct and semantically precise.

correct_sentence: Look! Linda's brother is playing computer games.

error_type: Determiner Error
error_severity: 2
error_description: Determiner Error: According to English proper noun usage rules, using the determiner 〈The〉 with the possessive proper noun 〈Linda's brother〉 creates a grammatical conflict because the possessive structure itself already provides specificity. Therefore, the superfluous 〈The〉 is deleted, retaining 『Linda's brother』 to ensure the expression is both grammatically correct and semantically precise.

correct_sentence: Listen and look! Linda's grandparents and Linda's little brother are watching TV.

error_type: Determiner Error
error_severity: 2
error_description: Determiner Error: According to English grammar rules, the proper noun 〈Linda's grandparents〉 itself already has a specific reference function and does not require the article 〈The〉; therefore, the superfluous determiner 〈The〉 is deleted to comply with the basic grammatical principle that "possessive structures do not take articles".

error_sentence: The Linda's grandparents with Linda's little brother is watching TV.
correct_sentence: Linda's grandparents and Linda's little brother are watching TV.
error: with
correction: and
error_type: Conjunction Error
error_severity: 3
error_description: Conjunction Error: According to English parallel structure rules, the coordinating conjunction 『and』 should be used to connect two parallel subjects; the original sentence incorrectly uses the preposition 〈with〉, leading to a logical error; therefore, 〈with〉 is changed to 『and』 to correctly connect the two parallel subject components 〈Linda's grandparents〉 and 〈Linda's little brother〉.

error_sentence: The Linda's grandparents with Linda's little brother is watching TV.
correct_sentence: Linda's grandparents and Linda's little brother are watching TV.

error_type: Subject-Verb Agreement Error
error_severity: 3
error_description: Subject-Verb Agreement Error: According to the principle of subject-verb agreement in English grammar, the plural subject 〈Linda's grandparents and Linda's little brother〉 requires a plural predicate verb; therefore, the singular verb 〈is〉 is changed to the plural form 『are』 to ensure agreement in number between the subject and the verb.

error_sentence: Oh, the Linda's mother is cooking.
correct_sentence: Oh, Linda's mother is cooking.
error: the
error_type: Determiner Error
error_severity: 2
error_description: Determiner Error: According to English grammar rules, the proper noun 〈Linda's mother〉, as a possessive form of a specific person, already has a specific reference function and does not require the additional article 〈the〉. Therefore, the superfluous determiner 〈the〉 is deleted to comply with the grammatical norm that "possessive proper nouns are not preceded by articles".

error_sentence: Linda is helping her mother doing housework.
correct_sentence: Linda is helping her mother do housework.
error: doing
correction: do
error_type: Nonfinite Verb Form Error
error_severity: 3
error_description: Nonfinite Verb Form Error: According to English collocation rules, in the verb phrase “help someone do something,” when help is used as an active voice verb, it is followed by an object plus the bare infinitive (i.e., the base form of the verb); the original sentence incorrectly uses the present participle 〈doing〉, so it is changed to the base form 『do』 to meet the grammatical requirement of this structure.

error_sentence: They all have a good time. !
correct_sentence: They all have a good time!
error: .
error_type: Punctuation Error
error_severity: 2
error_description: Punctuation Error: According to English punctuation rules, only one exclamation mark 〈!〉 is needed at the end of an exclamatory sentence; the original sentence uses both an exclamation mark and a period, causing punctuation redundancy. Therefore, the superfluous period 『.』 is deleted, retaining 『!』 to conform to standard English punctuation rules.
