error_type: Verb Tense Error
error_severity: 3
error_description: Verb Tense Error: The tense of the main clause 〈he had taught〉 is inconsistent with the present tense of the context; the intention here is to emphasize that the father's teaching has continued to the present, so the present perfect tense should be used, thus changing 〈he had taught〉 to 『has taught』.

error_sentence: If I quarrel with my good friends,
he will teach me how to get along well with my friends.
correct_sentence: If I quarrel with my good friends, he will teach me how to get along well with my friends.

error_type: Punctuation Error
error_severity: 2
error_description: Punctuation Error: The conditional adverbial clause “If I quarrel...” and the main clause “he will teach...” are incorrectly separated by a newline character, causing a break in sentence structure. Delete the newline character to keep the sentence coherent.

error_type: Verb Tense Error
error_severity: 3
error_description: Verb Tense Error: The present tense of the temporal adverbial clause 〈Once I have〉 conflicts with the past tense of the main clause 〈he did not scold〉. Change 〈have〉 to 『had』 to make the tense of the subordinate clause consistent with the main clause.

error_description: ① Punctuation Error: According to English expression habits, a comma is not needed before “but” in the parallel structure “did not scold..., but...”; ② Nonfinite Verb Form Error: The infinitive 〈to comfort〉 does not fit the parallel predicate structure. It needs to be changed to 『but comforted』 to maintain the parallel structure of the predicate verbs.
