error_description: ① Punctuation Error: According to English sentence structure rules, the independent clause 〈There are 4 people in my family〉 should be separated from the following explanatory content by a period. The original sentence incorrectly uses connecting symbols like 〈, :〉; it should be corrected to 『There are 4 people in my family.』 to comply with English writing norms; ② Determiner Error: According to the principle of numerical consistency, 〈both〉 strictly refers to a group of two, contradicting the four-person family (4 people) mentioned in the main clause. It should be replaced with the indefinite pronoun 『all』, which covers the entire group, to ensure the number of referents matches.
error_sentence: He likes reading best, he always reads different kinds of books in his free time.
correct_sentence: He likes reading best, and he always reads different kinds of books in his free time.
correction: and
error_type: Conjunction Error
error_severity: 3
error_description: Conjunction Error: According to English compound sentence writing norms, a connecting element is missing between the two independent clauses 〈He likes reading best〉 and 〈he always reads different kinds of books in his free time〉. The coordinating conjunction 『and』 should be added, retaining the comma, to form the standard structure 『He likes reading best, and he always reads...』.
error_sentence: My mother likes to see the movies, she likes comdy best.
correct_sentence: My mother likes to see movies, and she likes comedy best.

error_type: Determiner Error
error_severity: 2
error_description: Determiner Error: According to English article usage rules, the definite article 〈the〉 in the phrase 〈see the movies〉 implies specific movies, conflicting with the sentence's intended general meaning (the general activity of watching movies). The article should be deleted, changing it to 『see movies』 to comply with grammatical norms.
error_sentence: My mother likes to see the movies, she likes comdy best.
correct_sentence: My mother likes to see movies, and she likes comedy best.
correction: and
error_type: Conjunction Error
error_severity: 3
error_description: Conjunction Error: According to English grammar rules, a coordinating conjunction is missing between the two independent clauses 〈My mother likes to see movies〉 and 〈she likes...〉. Therefore, the coordinating conjunction 『and』 is added, preceded by a comma, modifying the structure to 『My mother likes to see movies, and she likes...』 to maintain sentence coherence.
error_sentence: My mother likes to see the movies, she likes comdy best.
correct_sentence: My mother likes to see movies, and she likes comedy best.
error: comdy
correction: comedy
error_type: Spelling Error
error_severity: 2
error_description: Spelling Error: According to English vocabulary spelling rules, 〈comdy〉 has incorrect letter order. The correct spelling for the meaning 'comedy' should be 『comedy』. Therefore, the misspelled word 〈comdy〉 is corrected to the noun 『comedy』 to conform to standard English spelling norms.
error_sentence: I like to do some games with my dogs, my dog is very clever and all of us like it.
correct_sentence: I like to play games with my dogs.
error: do some
correction: play
error_type: Word Redundancy Error
error_severity: 3
error_description: ① Verb Choice Error: According to English collocation principles, the verb 『play』 should be used with the noun 〈games〉 to express 'playing games', while 〈do some games〉 is not standard English usage. Therefore, the incorrect collocation 〈do some games〉 is changed to 『play games』 to comply with English verb-object collocation norms; ② Word Redundancy Error: According to common English expressions, the fixed phrase for 'playing games' is 'play games'. As 'games' refers to a type of activity, it does not require a determiner. Thus, there is word redundancy here; 〈some〉 needs to be deleted, modifying it to 『play games』.
error_sentence: I like to do some games with my dogs, my dog is very clever and all of us like it.
correct_sentence: I like to play games with my dogs. My dog is very clever and all of us like it.
error: , my
correction: . My
error_type: Punctuation Error
error_severity: 2
error_description: Punctuation Error: According to English grammar rules, the two complete sentences 〈I like to play games with my dogs〉 and 〈my dog is very clever〉 need to be separated by a period. Therefore, a terminal punctuation mark 『.』 is added to change the run-on sentence into separate independent clauses, and according to capitalization rules, the first letter of 〈my〉 is capitalized to 『My』 to comply with English sentence capitalization norms.
