error_type: Conjunction Error
error_severity: 5
error_description: ① Conjunction Error: The original sentence lacks a transitional conjunction, leading to incomplete semantics. According to the sentence's meaning, the conjunction 『but』 should be added after the adjective 〈happy〉 to clearly express the contrast between the preceding and succeeding clauses; ② Determiner Error: The definite article 〈the〉 in the phrase 〈the real happy〉 is redundant because the adjective 〈happy〉 is used in a general sense, not a specific one. Therefore, 〈the〉 is deleted to make the expression more idiomatic in English; ③ PoS Confusion Error: The structure of the original phrase 〈the real happy〉 is incorrect; the adjective 〈happy〉 needs to be modified by an adverb. Therefore, the determiner phrase 〈the real〉 is changed to the adverb 『really』 to correctly modify the adjective 〈happy〉, forming the standard collocation 『really happy』.

error_type: Conjunction Error
error_severity: 4
error_description: ① Conjunction Error: The conjunction 〈But〉 at the beginning of the sentence is acceptable in informal contexts, but in formal writing, it should be replaced with the more standard 『However』, followed by a comma, to meet the standards of written English expression; ② Punctuation Error: According to English expression norms, a comma is needed after the conjunction 『However』 to separate it from the following clause. Therefore, the original sentence is modified to 『However,』 to enhance formality and more accurately express the transitional relationship.

correct_sentence: However, the community service made me feel really happy.
