error_type: Punctuation Error
error_severity: 3
error_description: ① Punctuation Error: According to English syntax rules, in a complete compound sentence, the time adverbial 〈Once upon a time〉 at the beginning of the sentence should be separated from the main clause by a comma, not a period. Therefore, 〈.〉 needs to be changed to 『,』 to comply with English syntax rules; ② Case Error: Based on the previous modification, 〈There〉 is not the first word in the compound sentence and needs to be changed to lowercase 『there』 to comply with syntax rules.

error_sentence: There were many trees, a small stream flowing eastward.
correct_sentence: Once upon a time, there were many trees, and a small stream flowing eastward.
correction: and
error_type: Conjunction Error
error_severity: 3
error_description: Conjunction Error: According to English syntax rules, the original phrases 〈many trees〉 and 〈a small stream flowing eastward〉 are the only two parallel sentence components after 〈There were〉, and they need to be connected by a comma and a conjunction. Therefore, there is a conjunction error here. The coordinating conjunction 『and』 needs to be added before 〈a small stream flowing eastward〉 to comply with English syntax rules and make the meaning coherent.

error_sentence: The scenery was very beautiful, but now there are apartments built on the lawn, asphalt rodes, and many car.
correct_sentence: The scenery was very beautiful, but now there are apartments built on the lawn, asphalt roads, and many cars, which are quite different from the old days.
error: rodes
correction: roads
error_type: Spelling Error
error_severity: 2
error_description: Spelling Error: According to English spelling conventions, the correct spelling for the plural form of the English word "road" is "roads", thus there is a spelling error here. The incorrect spelling 〈rodes〉 needs to be changed to 『roads』 to comply with English spelling conventions.

error_sentence: The scenery was very beautiful, but now there are apartments built on the lawn, asphalt rodes, and many car. Which are qite different from the old days.
correct_sentence: The scenery was very beautiful, but now there are apartments built on the lawn, asphalt roads, and many cars, which are quite different from the old days.
error: car. Which are qite
correction: cars, which are quite
error_type: Noun Number Error
error_severity: 5
error_description: ① Noun Number Error: According to the original sentence's meaning, it refers to "many cars," requiring the plural form of the countable noun "car". Therefore, the singular 〈car〉 needs to be changed to 『cars』 to match the intended meaning; ② Punctuation Error: According to English syntax rules, a non-restrictive relative clause needs to be separated from the main clause by a comma, so there is a punctuation error here. 〈. Which〉 needs to be changed to 『, which』 to comply with English syntax rules; ③ Spelling Error: According to the original sentence's meaning, it intends to express "quite different," and the correct spelling for the adverb "quite" is "quite". The incorrect spelling 〈qite〉 needs to be changed to 『quite』 to match the intended meaning.
