error_type: Verb Tense Error
error_severity: 3
error_description: Verb Tense Error: According to the context, the time adverbial 〈at 8:00〉 indicates a 'daily routine/habit', which is typically expressed using the simple present tense in English. Therefore, there is a verb tense error; the simple future tense 〈will go〉 should be changed to the simple present tense 『go』 to better conform to English expression habits.
error_sentence: I am begin to class.
correct_sentence: I begin class.
error: am begin to
correction: begin
error_type: Nonfinite Verb Form Error
error_severity: 5
error_description: ① Auxiliary Error: As a verb, 〈begin〉 in the simple present tense does not require the auxiliary verb 〈am〉; therefore, 〈am begin〉 should be changed to 『begin』 to comply with English grammar rules; ② Nonfinite Verb Form Error: 〈begin〉 can be directly followed by a noun to mean 'start something'; thus, 'start class' can be expressed directly as begin class, so 〈to class〉 should be changed to 『class』 to better conform to English grammar norms.
error_sentence: I have four class in the morning, the four class in the afteroon.
correct_sentence: I have four classes in the morning and four classes in the afternoon.
error: class
correction: classes
error_type: Noun Number Error
error_severity: 3
error_description: Noun Number Error: The numeral 〈four〉 should be followed by a plural noun; therefore, the countable noun 〈class〉 needs to be in its plural form, changed to 『classes』 to maintain number agreement according to English grammar.
error_sentence: I have four class in the morning, the four class in the afteroon.
correct_sentence: I have four classes in the morning and four classes in the afternoon.
error: , the four class
correction: and four classes
error_type: Conjunction Error
error_severity: 5
error_description: ① Conjunction Error: The two parallel objects in this sentence need to be connected by the conjunction 〈and〉 to maintain coherence; therefore, 〈, the〉 should be changed to 『and』 to comply with English grammar; ② Noun Number Error: The numeral 〈four〉 should be followed by a plural noun; therefore, the countable noun 〈class〉 needs to be in its plural form, changed to 『classes』 to maintain number agreement according to English grammar.
error_sentence: I have four class in the morning, the four class in the afteroon.
correct_sentence: I have four classes in the morning and four classes in the afternoon.
error: afteroon
correction: afternoon
error_type: Spelling Error
error_severity: 2
error_description: Spelling Error: According to the sentence's meaning, the intention is to express 'afternoon'; therefore, 〈afteroon〉 in the original sentence is a spelling error and should be corrected to the proper spelling 『afternoon』 to comply with English spelling conventions.
error_sentence: I have lunch on school canteen at 12:00.
correct_sentence: I have lunch in the school canteen at 12:00.
error: on
correction: in the
error_type: Preposition Error
error_severity: 5
error_description: ① Preposition Error: In English, when expressing 'eating in the canteen', the preposition 『in』 should be used instead of 〈on〉, so 〈on〉 must be changed to 『in』 to conform to the standard collocation for this prepositional phrase; ② Determiner Error: In English, when referring to a specific item, a definite article is needed before it; therefore, the definite article 『the』 should be added before the singular countable noun 〈school canteen〉 to specify the school canteen and satisfy the usage rules for countable nouns.
error_sentence: I am go home at after school.
correct_sentence: I go home after school.
error: am
error_type: Auxiliary Error
error_severity: 3
error_description: Auxiliary Error: According to the context, the simple present tense is required here. The redundant auxiliary verb 〈am〉 combined with the base form verb 〈go〉 forms an incorrect structure; therefore, there is an auxiliary error, and 〈am〉 needs to be deleted to form the correct simple present tense 『go』 according to English grammar.
error_sentence: I am go home at after school.
correct_sentence: I go home after school.
error: at
error_type: Word Redundancy Error
error_severity: 3
error_description: Word Redundancy Error: In English, 〈after school〉 means 'after school' and is a fixed phrase, typically used as a time adverbial at the end of a sentence; therefore, the redundant preposition 〈at〉 needs to be deleted to conform to the fixed English expression for 'after school'.
