error_type: Determiner Error
error_severity: 2
error_description: Determiner Error: The phrase 'a lot of places of interest' is a general reference and does not require the definite article 〈the〉. Deleting 〈the〉 makes it more grammatically correct, and the sentence expression more natural and fluent.
error_sentence: I also ate many Chinese food, they were delicious , I like them a lot.
correct_sentence: I also ate many Chinese foods. They were delicious.
error: food, they
correction: foods. They
error_type: Noun Number Error
error_severity: 3
error_description: ① Noun Number Error: 〈food〉 is an uncountable noun, but here it refers to various types of food and should use the plural form 『foods』 to comply with grammatical rules; ② Punctuation Error: 〈 I also ate many Chinese foods〉 and 〈They were delicious〉 contain independent predicate structures/subject-verb structures and can stand as independent sentences, so a period instead of a comma is needed after 『foods』.
error_sentence: I also ate many Chinese food, they were delicious , I like them a lot.
correct_sentence: They were delicious. I liked them a lot.
error: , I like
correction: . I liked
error_type: Verb Tense Error
error_severity: 4
error_description: ① Punctuation Error: 〈 they were delicious〉 and 〈I liked them a lot〉 contain independent predicate structures/subject-verb structures and can stand as independent sentences, so the comma needs to be changed to a period; ② Verb Tense Error: According to the contextual time logic (Last week), the past tense is required here, so the present tense 〈like〉 is changed to the past tense 『liked』 to maintain tense consistency.
