error_type: Verb Tense Error
error_severity: 3
error_description: Verb Tense Error: According to the context, the entire sentence describes past thoughts and actions, so the past tense should be used. In the original sentence, 〈want〉 is in the simple present tense, which is inconsistent with the overall past tense context. Change 〈want〉 to the past tense form 『wanted』 to maintain tense consistency and conform to grammatical rules and semantic logic.
error_sentence: So I want to go out to see it and I wanted to take some photos.

correct_sentence: So I wanted to go out to see it and wanted to take some photos.

error_type: Word Redundancy Error
error_severity: 3
error_description: Word Redundancy Error: In the parallel structure “and I wanted to take some photos”, the subject 〈I〉 has already appeared before; its reoccurrence here causes word redundancy. In English expression habits, to make the sentence concise and fluent, the repeated subject should be omitted. Delete the second 〈I〉 to make the sentence expression more concise and natural.

error_description: Punctuation Error: According to English punctuation rules, a comma is needed to separate the adverbial clause of time 〈When I saw...〉 from the main clause 〈I was so happy〉; the original sentence lacks a comma. Add 『,』 after 〈view〉 to make the sentence structure clear.

error_severity: 2
error_description: Noun Number Error: According to English grammar rules, “take photos” is a fixed expression meaning “to take pictures”, indicating multiple photos. In the original sentence, 〈photo〉 is in the singular form, which does not fit the context; it needs to be changed to the plural form 『photos』 to make the expression conform to semantic and grammatical rules.

error_description: ① Verb Tense Error: According to the context, the tense is simple past; 〈thanks〉 is simple present, which does not meet the tense requirement and needs to be changed to the past tense 『thanked』 to maintain tense consistency; ② Preposition Error: The structure “thank for” should be followed by a specific thing, not a person; here, using 『thanked me』 directly is more in line with grammatical rules.

error_type: Auxiliary Error
error_severity: 3
error_description: Auxiliary Error: When a “so that” clause expresses purpose, the modal verb 『would』 should be used to indicate future possibility; the original sentence incorrectly uses the past tense 〈didn't〉. It should be changed to 『wouldn't』 to express a hypothetical mood.
