error_type: Verb Choice Error
error_severity: 4
error_description: ① Verb Tense Error: According to the context, the sentence describes an action that happened in the past. In the original sentence, 〈go〉 is in the present simple tense, which does not meet the tense consistency requirement. 〈go〉 should be changed to the past tense to maintain tense consistency with the context; ② Verb Choice Error: In English, the phrase “get wet” is commonly used to express “getting wet”. The original sentence uses 〈go wet〉, which is not idiomatic. “get wet” should be used; here, it is prioritized as a verb tense error, changing 〈go〉 to 『got』.

error_description: ① Verb Tense Error: According to the overall context of the sentence, it describes a past state. In the original sentence, 〈feel〉 and 〈have〉 are in the present simple tense, which does not meet the tense requirement. 〈feel〉 should be changed to the past tense 『felt』, and 〈have〉 should be changed to the past tense 『had』 to match the overall past tense narration; ② Space Error: The word 〈feelcold〉 is not correctly separated and lacks a necessary space. A space should be added between 〈feel〉 and 〈cold〉, changing 〈feelcold〉 to 『feel cold』 to make the word spelling conform to standards.

error_description: Spelling Error: According to the meaning of the sentence, it is clear that the intention here is to express “and”, but 〈angd〉 is misspelled. The correct spelling for the conjunction should be 『and』. 〈angd〉 needs to be changed to 『and』 to make the sentence spelling correct and conform to English expression norms.
