error_type: Noun Number Error
error_severity: 4
error_description: ① Noun Number Error: According to English grammar rules, when the number 〈four〉 precedes a countable noun, the noun must be in its plural form; the noun 〈ball〉 in the original sentence is singular and should be changed to 『balls』; ② Punctuation Error: According to English writing conventions, in a compound sentence, when the conjunction 〈but〉 connects two logically related parts, a comma is usually required before it; the original sentence lacks a comma, so a 『,』 should be added after 〈balls〉; ③ Case Error: According to English writing conventions, the first-person pronoun 〈i〉 used as a subject in a sentence should be capitalized; the pronoun 〈i〉 in the original sentence is not capitalized and should be changed to 『I』.

error_type: Sentence Structure Error
error_severity: 4
error_description: ① Punctuation Error: According to English grammar rules, independent clauses cannot be joined by a comma; a period is required for separation. The comma 〈,〉 in the original sentence should be replaced with a period 『.』 to separate the two independent sentences; ② Case Error: According to English writing conventions, the first-person pronoun used as a subject in a sentence must be capitalized; the pronoun 〈i〉 in the original sentence should be changed to 『I』 to comply with English capitalization rules; ③ Sentence Structure Error: The original sentence intends to express "I just watch soccer games on TV," but in English sentence structure, the adverbial phrase 〈on TV〉 cannot be placed directly after the subject as it causes logical confusion; it should be placed after the verb. Therefore, 〈on TV〉 should be deleted here.

error_sentence: but i never play soccer , i just on TV watch soccer game.
correct_sentence: I just watch soccer games on TV.
error: game
correction: games on TV
error_type: Sentence Structure Error
error_severity: 4
error_description: ① Noun Number Error: According to English grammar rules, when referring generally to multiple matches, the countable noun 〈game〉 must be in its plural form; the noun 〈game〉 in the original sentence is singular, inconsistent with the context, and should be changed to 『games』; ② Sentence Structure Error: According to English expression habits and the sentence's meaning, expressing watching "on TV" requires adding the prepositional phrase 『on TV』. In the original sentence 〈i just on TV watch soccer game.〉, 〈on TV〉 appears after the subject; after deleting this part (as in edit 2), this phrase should be added at the end of the sentence to clarify the adverbial. Therefore, the original phrase 〈on TV watch soccer game.〉 needs to be modified to 『watch soccer games on TV』 to comply with grammar rules and expression habits.

error_type: Conjunction Error
error_severity: 3
error_description: ① Conjunction Error: According to English grammar rules, if there is a contrast relationship between two clauses, a conjunction is needed to clarify the logic. In the sentence, 〈Mike likes basketball〉 and 〈he doesn’t like ping - pong〉 have a contrast relationship, but the original sentence lacks a conjunction. Therefore, 『but』 should be added after 〈basketball〉, changing it to 『Mike likes basketball, but he doesn’t like ping - pong』 to clearly express the contrast.

error_type: Nonfinite Verb Form Error
error_severity: 3
error_description: ① Nonfinite Verb Form Error: According to English grammar rules, when the verb 〈like〉 is followed by another verb, either the infinitive structure "like to do" or the gerund structure "like doing" must be used. The verb 〈play〉 in the original sentence is in its base form, which violates grammar rules and constitutes a nonfinite verb form error. 『to』 needs to be added before 〈play〉 to form 『likes to play』, making the sentence grammatically correct.
