correct_sentence: This Friday afternoon my parents and I are going to move our house.
error: me
correction: I
error_type: Pronoun Error
error_severity: 3
error_description: Pronoun Error: According to English grammar rules, pronouns in the subject position should use the subjective case. In the original sentence, 〈me〉 is in the subject position, which is a pronoun error; 〈me〉 should be changed to the subjective pronoun 『I』, so that 〈my parents and I〉 maintains subjective case consistency, conforming to subject-verb agreement rules.

error_sentence: As you know, moving is not a easy work, and I am afraid that I can't do the chores by myself, so I need your help.
correct_sentence: As you know, moving is not an easy task, and I am afraid that I can't do the chores by myself, so I need your help.
error: a easy work
correction: an easy task
error_type: Noun Error
error_severity: 3
error_description: ① Determiner Error: According to English grammar rules, before words beginning with a vowel sound, the indefinite article should be 『an』; in the original sentence, using 〈a〉 before 〈easy〉 does not conform to the rule and should be changed to 『an』; ② Noun Error: According to the sentence meaning, the intention here is to express “an easy task”; 〈work〉 is an uncountable noun and not suitable for this context, it should be changed to the countable noun 『task』 to clearly express the concept of a task.

error_sentence: First, you can come to my house at noon, we can sweep the floor, clean up the living room, and take out the rubbish.
correct_sentence: First, you can come to my house at noon. We can sweep the floor, clean up the living room, and take out the rubbish.
error: , we
correction: . We
error_type: Punctuation Error
error_severity: 2
error_description: ① Punctuation Error: According to English grammar rules, a comma 〈,〉 cannot connect two independent clauses; in the original sentence, 〈you can come...〉 and 〈we can sweep...〉 are two independent clauses, so the comma should be changed to a period 『.』 for correct separation; ② Case Error: According to English writing conventions, the first letter of the word at the beginning of a sentence needs to be capitalized; in the original sentence, 〈we〉 is at the beginning of the sentence and should be changed to the capitalized 『We』 to conform to the convention.

error_sentence: After that, we need to move the furnitures together.
correct_sentence: After that, we need to move the furniture together.
error: furnitures
correction: furniture
error_type: Noun Number Error
error_severity: 3
error_description: Noun Number Error: According to English grammar rules, 〈furniture〉 is an uncountable noun and has no plural form; in the original sentence, 〈furnitures〉 is an incorrect plural form and should be changed to 『furniture』 to conform to grammar rules.

error_sentence: It might be a bit tired, but I think we will be happy because of each other.
correct_sentence: It might be a bit tiring, but I think we will be happy because of each other.
error: tired
correction: tiring
error_type: Adjective Error
error_severity: 3
error_description: Adjective Error: According to English grammar rules, 〈tired〉 is used to describe a person subjectively “feeling tired,” whereas here it describes the characteristic of the thing itself being “tiring”; 『tiring』 is needed, therefore 〈tired〉 is changed to 『tiring』 to fit the context.

error_sentence: In the end, I'd like to invite you to go shopping with me, I want to buy some new clothes.
correct_sentence: In the end, I'd like to invite you to go shopping with me.
error: ,
correction: .
error_type: Punctuation Error
error_severity: 2
error_description: Punctuation Error: In English, 〈I'd like to invite you to go shopping with me〉 and 〈I want to buy some new clothes〉 contain independent predicate structures and can stand as independent sentences; therefore, a comma 〈,〉 cannot connect two independent clauses and should be changed to a period 『.』 to separate the sentence structures.

error_sentence: You can also buy something that you are interested.

correct_sentence: You can also buy something that you are interested in.

correction: in
error_type: Preposition Error
error_severity: 2
error_description: Preposition Error: According to English grammar rules, the phrase 〈be interested〉 needs to be paired with the preposition “in” to fully express the meaning of “being interested in...”; the preposition is missing in the original sentence, making it incomplete. Therefore, 『in』 needs to be added at the end of the sentence to clarify the object of the action and complete the sentence structure.

error_sentence: Best wishes,L
correct_sentence: Best wishes,
L
correction: 

error_type: Space Error
error_severity: 1
error_description: Space Error: According to English writing conventions, when the letter closing “Best wishes,” is followed by a signature, a space should be kept between the comma and the signature. In the original sentence 〈Best wishes,L〉, a space is missing between the comma and “L”, and it should be changed to 『Best wishes, L』 to conform to the convention.
