error: very
correction: so
error_type: Conjunction Error
error_severity: 3
error_description: Conjunction Error: The fixed phrase “so...that” structure requires 『so』 instead of 〈very〉 to express a cause-and-effect relationship, meaning “so...that...”, indicating that the degree of the preceding situation or action leads to the occurrence of the subsequent result; therefore, 〈very〉 is changed to 『so』 to correctly express the causal relationship.
error_sentence: Liu Linlin loves sports a lot that she does sports everyday for at least two hours.
correct_sentence: Liu Lili loves sports so much that she does sports every day for at least two hours.
error: Linlin
correction: Lili

error_description: Noun Error: The name 〈Liu Linlin〉 is inconsistent with 〈Liu Lili〉 in the context; therefore, 〈Linlin〉 is changed to 『Lili』 to ensure name consistency.
error_sentence: Liu Linlin loves sports a lot that she does sports everyday for at least two hours.
correct_sentence: Liu Lili loves sports so much that she does sports every day for at least two hours.
error: a lot
correction: so much
error_type: Conjunction Error
error_severity: 3
error_description: Conjunction Error: The collocation 〈a lot that〉 is used incorrectly; the sentence after 〈that〉 needs to express a result. Here, 『so much』 should be used to connect the two parts, indicating degree; therefore, 〈a lot〉 is changed to 『so much』 to correctly express the meaning.

correct_sentence: Liu Lili loves sports so much that she does sports every day for at least two hours.

error_type: Adverb Error
error_severity: 3
error_description: Adverb Error: 〈everyday〉 is an adjective meaning “daily” or “ordinary,” while here the adverbial phrase 〈every day〉 meaning “each day” is needed as a time adverbial; therefore, 〈everyday〉 is changed to 『every day』 to correctly express the meaning.

error_type: Pronoun Error
error_severity: 3
error_description: ① Preposition Error: The verb 〈laugh〉 should be followed by the preposition 〈at〉 to form “laugh at...”, which refers to laughing at someone or something; therefore, 〈to〉 is changed to 『at』. ② Pronoun Error: In negative sentences, we generally use 『anyone』 to mean “not any person,” while 〈every one〉 is usually used to emphasize each individual and is more often used in affirmative sentences or selective expressions; therefore, 〈every one〉 should be replaced with the indefinite pronoun 『anyone』 to comply with grammatical rules.
error_sentence: She never laughs to every one, and she never had jokes to others.
correct_sentence: She never laughs at anyone, and she never makes jokes to others.
error: had

error_type: Verb Choice Error
error_severity: 3
error_description: Verb Choice Error: According to English grammar rules, “make jokes to someone” means to tell jokes to someone. The context is in the simple present tense; therefore, the past tense〈had〉 needs to be changed to the present tense 『makes』 to maintain tense consistency.

correction: tells
error_type: Verb Choice Error
error_severity: 3
