There was a small lake there ten years ago, and there weren't any roads in this part. But now look, there are many cars runing on the wide roads. There were lots of bushes in the field at that time, but now there aren't any bushes here. Instead, many tall buildings are built in this place. Everything has change!

error_description: Spelling Error: According to English spelling rules for negation words, 〈ho〉 is a misspelling of 『no』, with the letters inverted. The sentence context 『There were no houses』 requires a negative meaning, so the misspelled 〈ho〉 must be corrected to the negative adverb 『no』, which follows basic English vocabulary spelling rules, to ensure semantic and spelling accuracy.

error_sentence: But now look, there are many cars runing on the wide roads.
correct_sentence: But now look, there are many cars running on the wide roads.
error: runing
correction: running
error_type: Spelling Error
error_severity: 2
error_description: Spelling Error: According to the rules for forming English present participles, the monosyllabic verb 〈run〉 ends with a single vowel 'u' + a single consonant 'n', meeting the condition for doubling the final consonant in a stressed closed syllable. The original word 〈runing〉 incorrectly omits the second consonant 'n'; therefore, the final consonant 'n' must be doubled before adding -ing, correcting it to the grammatically correct present participle form 『running』 to accurately express the meaning of 'running'.

error_type: Verb Tense Error
error_severity: 3
error_description: Verb Tense Error: According to the rules for forming the English present perfect tense, the auxiliary verb 〈has〉 must be paired with the past participle form of the verb to construct the tense structure. The base form of the verb 〈change〉 in the original sentence does not meet this grammatical requirement; therefore, it needs to be converted to the past participle form of the regular verb, 『changed』, to form the correct present perfect structure 『has changed』, complying with the morphological requirements for the perfect tense in English grammar.
