Student essay:
A harmonious family should be full of warmth, love and laughter. We should love and show concern for each other. They also respect and understand each other. The children who live in a harmonious family will be optimistic. The parents who live in a harmonious family will be healthy and happy.

First, parents should be a role model for their children. They should pay more attention to their words and behavior. Then, they need to believe their children and often communicate with them.
As children of the family, we should also respect and understand our parents, and try to share their burdens. If we do so, our home will always be harmonious.

error_severity: 2
error_description: Punctuation Error: According to English punctuation rules (especially the Oxford comma rule), in a series of items 〈warmth, love and laughter〉, a comma should be added before the last element to clearly separate each item, thus it is revised to 『warmth, love, and laughter』 to make the sentence structure clearer.

error: They
correction: We should
error_type: Verb Choice Error
error_severity: 4
error_description: ① Pronoun Error: According to the principle of subject consistency in context, the subject of the preceding sentence is 〈We〉, and an abrupt shift to 〈They〉 in the following sentence would cause a logical break; therefore, 〈They〉 is changed to 『We should』 to maintain subject uniformity and ensure semantic coherence; ② Verb Choice Error: The original sentence lacks a modal verb, leading to a vague tone; according to the intended meaning (expressing a suggestion), 『should』 needs to be added to make the suggestive tone explicit, thereby enhancing the expressive effect.

error_type: Adjective Error
error_severity: 2
error_description: Adjective Error: According to English adjective usage rules, when describing the subject's feeling, 〈relaxed〉 (feeling relaxed) should be used instead of 〈relaxing〉 (causing relaxation). Here the subject is 『we』 (students), indicating the students' state, therefore it should be modified to 『we feel relaxed』 to conform to semantic logic.
error_sentence: After the class we have various activities, we usually run in the playground, and boys like to play basketball more.

correction: . We
error_type: Punctuation Error
error_severity: 3
error_description: ① Punctuation Error: According to English grammar rules, connecting two independent clauses 〈After the class we have various activities〉 and 〈we usually run...〉 with only a comma creates a comma splice (comma splice). A period should be used to separate independent sentences, therefore 〈, we〉 is modified to 『. We』 to correct the sentence structure; ② Case Error: According to English writing conventions, the first letter of the first word in a sentence must be capitalized, therefore 〈we〉 is changed to 『We』 to ensure the sentence beginning conforms to standard format.
