error_description: ① Punctuation Error: According to English grammar rules, two independent clauses should be connected by a comma, not a period; in the original sentence, 〈with the development of science and technology〉 and 〈Cars become increasingly popular〉 are two clauses, so 〈.Cars〉 is changed to 『, cars』 to comply with grammar; ② Verb Tense Error: According to the context, this action should use the present perfect tense, while in the original sentence 〈become〉 is in the simple present tense, so 〈become〉 needs to be changed to the present perfect tense 『have become』 to fit the context.
