correction: going to
error_type: Auxiliary Error
error_severity: 3
error_description: Auxiliary Error: According to English grammar rules, the fixed phrase “be going to do something” means “plan to do something.” Based on the original sentence's meaning, it intends to express “I plan to visit my grandparents next weekend”; there is an auxiliary error here. 『going to』 needs to be added before 〈visit〉 to conform to the context and grammatical rules.
error_sentence: I am visit my grandparents at my next weekend
correct_sentence: I am going to visit my grandparents next weekend.
error: at my
error_type: Word Redundancy Error
error_severity: 3
error_description: Word Redundancy Error: According to English syntax rules, the structure “next + specific time” can function as a time adverbial at the end of a sentence to indicate future time without needing prepositions or other determiners. Therefore, there is a word redundancy error here. The redundant 〈at my〉 needs to be deleted to conform to English syntax rules and the original sentence's meaning.
error_sentence: I am visit my grandparents at my next weekend
correct_sentence: I am going to visit my grandparents next weekend.
correction: .
error_type: Punctuation Error
error_severity: 2
error_description: Punctuation Error: According to English syntax rules, the end of an independent sentence needs to be marked with an appropriate punctuation mark to indicate the sentence's conclusion; the original sentence is missing a period at the end, thus there is a punctuation error here. A 『.』 needs to be added after 〈weekend〉 to mark the end of the sentence to conform to English syntax rules.

error_type: Nonfinite Verb Form Error
error_severity: 5
error_description: ① Subject-Verb Agreement Error: According to English grammar rules, the original sentence has a subject-verb agreement error; the subject 〈Gao Feng〉 is third-person singular, and the original predicate 〈like〉 is in the third-person plural form, so the verb 〈like〉 needs to be changed to the third-person singular form 『likes』 to maintain subject-verb agreement; ② Nonfinite Verb Form Error: According to English grammar rules, the verb 〈like〉 requires a gerund form as its object to maintain grammatical correctness, so 〈play〉 needs to be changed to 『playing』 to ensure grammatical correctness; ③ Space Error: According to writing conventions, there should be no space between the words 〈foot〉 and 〈ball〉, so 〈foot ball〉 is changed to 『football』 to conform to writing conventions.
error_sentence: He has four foot ball, but he never play football.
correct_sentence: He has four footballs, but he never plays football.
error: foot ball
correction: footballs
error_type: Noun Possessive Error
error_severity: 2
error_description: ① Space Error: According to English writing conventions, the correct spelling of "football" is "football", so the space between 〈foot〉 and 〈ball〉 is removed to conform to writing conventions; ② Noun Number Error: According to English grammar rules, "football" should be in the plural form 『footballs』 to agree with the numeral 〈four〉, so "football" should be changed to 『footballs』 to comply with English grammar rules.
error_sentence: He has four foot ball, but he never play football.
correct_sentence: He has four footballs, but he never plays football.
error: play
correction: plays
error_type: Subject-Verb Agreement Error
error_severity: 3
error_description: Subject-Verb Agreement Error: According to English grammar rules, the original sentence has a subject-verb agreement error; the subject 〈he〉 is third-person singular, and the original predicate 〈play〉 is in the third-person plural form, so the verb 〈play〉 needs to be changed to the third-person singular form 『plays』 to maintain subject-verb agreement.

Error analysis:
error_sentence: Last Saturday, I am geted up early.
correct_sentence: Last Saturday, I got up early.
error: am geted
correction: got
error_type: Verb Tense Error
error_severity: 3
error_description: ① Verb Tense Error: According to the prompt, "Last weekend" describes a past event, requiring the simple past tense; 〈am〉 indicates the present tense, inconsistent with the past time adverbial 〈Last Saturday〉, and needs to be changed to the past tense; ② Spelling Error: 〈geted〉 is the incorrect past tense form of the verb 〈get〉; the correct form is 『got』. Therefore, 〈am geted〉 is modified to 『got』 to conform to grammatical rules.
error_sentence: I and my friend played in the park.
correct_sentence: My friend and I played in the park.
error: I and my friend
correction: My friend and I
error_type: Word Order Error
error_severity: 4
error_description: Word Order Error: According to English expression conventions, the personal pronoun 〈I〉 is usually placed after other subjects in a sentence; therefore, 〈I and my friend〉 needs to be adjusted to 『My friend and I』 to conform to standard English usage.
error_sentence: I like play baskeball, so I am played basketball.
correct_sentence: I like to play basketball, so I played basketball.
error: play baskeball
correction: to play basketball
error_type: Nonfinite Verb Form Error
error_severity: 4
error_description: ① Nonfinite Verb Form Error: According to English grammar rules, the verb 〈like〉 should be followed by an infinitive structure; therefore, 『to』 needs to be added after 〈like〉 in the original sentence to form 『like to play』 to conform to grammatical rules; ② Spelling Error: According to the sentence's meaning, the intended word is "basketball"; thus, 〈baskeball〉 is a misspelling of 『basketball』 and needs to be corrected to 『basketball』 for the sentence to make sense.
error_sentence: I like play baskeball, so I am played basketball.
correct_sentence: I like to play basketball, so I played basketball.
error: am
error_type: Verb Tense Error
error_severity: 3
error_description: Verb Tense Error: According to the prompt, "Last weekend" describes a past event, requiring the simple past tense; the original sentence incorrectly adds the present tense auxiliary verb 〈am〉; the past tense form 『played』 should be used directly to maintain tense consistency. Therefore, 〈am played〉 needs to be changed to the simple past tense 『played』 to fit the context.

error: We we're
correction: We were
error_type: Spelling Error
error_severity: 2
error_description: Spelling Error: According to the sentence meaning, this should be the past tense of 'to be', therefore 〈we're〉 is a misspelling of 『were』, and needs to be changed to 『were』 to make the sentence coherent.
error_sentence: It has P.E, English corner and so on.
correct_sentence: It had P.E., English corner and so on.
error: has P.E
correction: had P.E.
error_type: Verb Tense Error
error_severity: 4
error_description: ① Verb Tense Error: According to the prompt, 'last Friday' describes an event that happened in the past and should use the simple past tense, whereas 〈has〉 in the original sentence is in the simple present tense, so 〈has〉 needs to be changed to the simple past tense 『had』 to fit the context; ② Punctuation Error: According to English writing conventions, the abbreviation for the subject 『P.E.』 needs to retain the period, so the original 〈P.E〉 needs to be changed to 『P.E.』 to conform to writing standards.
error_sentence: We took part in it and development.
correct_sentence: We took part in it and developed.
error: development
correction: developed
error_type: PoS Confusion Error
error_severity: 3
error_description: PoS Confusion Error: According to English grammar rules, 〈development〉 is a noun, whereas a verb is needed here to form a parallel structure with 〈took part〉, therefore 〈development〉 in the original sentence needs to be changed to the past tense verb 『developed』 to conform to grammatical rules.
Writing prompt: Using the given vocabulary and sentence patterns, and referring to the picture, write a short essay. It is 3 PM. Based on the information provided below about Linda, use the present continuous tense to describe what Linda sees and hears at the mall:

It's 3 o'clock. Linda is in the mall. She is seeing a little girl is buying some food. A young lady is looking at a dress. Linda's mother is trying the shoes. Linda's father is staying on the sofa and waiting for Linda's mother.

Corrected essay:
It's 3 o'clock. Linda is in the mall. She sees a little girl buying some food. A young lady is looking at a dress. Linda's mother is trying on the shoes. Linda's father is staying on the sofa and waiting for Linda's mother.

Error analysis:
error_sentence: She is seeing a little girl is buying some food.
correct_sentence: She sees a little girl buying some food.
error: is seeing
correction: sees
error_type: Verb Tense Error
error_severity: 3
error_description: Verb Tense Error: According to English expression habits, the sensory verb 〈see〉, when expressing perception, is usually used in the simple present tense. In the original sentence, 〈is seeing〉 is in the present continuous tense, which does not conform to the usage rules of 〈see〉. 〈is seeing〉 should be changed to the simple present tense 『sees』 to accurately express the perceptual state of “seeing”.
error_sentence: She is seeing a little girl is buying some food.
correct_sentence: She sees a little girl buying some food.
error: is
error_type: Word Redundancy Error
error_severity: 4
error_description: Word Redundancy Error: According to English grammar rules, when the sensory verb 〈see〉 is followed by an object, if it indicates an ongoing action of the object, the subsequent verb should be in the present participle form. In the original sentence, the structure “a little girl is buying some food” is incorrect, with a redundant 〈is〉. 〈is〉 should be deleted, and 〈is buying〉 should be changed to 『buying』.
error_sentence: Linda's mother is trying the shoes.
correct_sentence: Linda's mother is trying on the shoes.
correction: on
error_type: Preposition Error
error_severity: 2
error_description: Preposition Error: According to English fixed collocation rules, “try on” is a fixed phrase expressing “to try on”. In the original sentence “Linda's mother is trying the shoes”, the preposition “on” is missing, leading to incomplete semantics. “on” should be added after 〈trying〉, changing 〈trying the shoes〉 to 『trying on the shoes』, to clearly express the action of “trying on shoes” and make the sentence conform to English expression habits.

Error analysis:
error_sentence: Tomorrow is Saturday . Saturday morning, I am going to do my homework .
correct_sentence: On Saturday morning, I am going to do my homework.
correction: On
error_type: Preposition Error
error_severity: 3
error_description: ① Space Error: According to English writing conventions, there should be no space between the last word of a sentence and the period. The original phrase 〈Saturday .〉 has an extra space, so it needs to be changed to 『Saturday.』 to conform to writing standards; ② Preposition Error: According to English usage, the preposition 『On』 is used before specific dates. The time adverbial 〈Saturday morning〉 requires the preposition 『On』 before it to form a complete temporal expression.
error_sentence: I am going to do clean with my mother .
correct_sentence: I am going to clean with my mother.
error: do
error_type: Word Redundancy Error
error_severity: 3
error_description: Word Redundancy Error: According to the prompt, the phrase 『do cleaning』 should be used. However, the original sentence uses 〈clean〉 directly as a verb. It should be changed to the gerund phrase form to express the cleaning activity more accurately. Therefore, 〈clean〉 needs to be modified to 『do cleaning』 to meet the prompt's requirement. This was not modified according to the prompt, constituting over-correction.
error_sentence: I have a happy Saturday .
correct_sentence: I am going to have a happy Saturday.
correction: am going to
error_type: Verb Tense Error
error_severity: 3
error_description: Verb Tense Error: Based on the context and prompts, the sentence describes planned future activities and should use the future tense. The original sentence uses 〈have〉 in the simple present tense, which is a tense error. Therefore, 〈have〉 needs to be changed to 『am going to have』 to express a planned future action, fitting the context.

error_type: Determiner Error

error_description: ① Space Error: According to English writing conventions, a space is needed between words; the original sentence lacks the necessary space in 〈homeworkat〉, so the joined 〈homeworkat〉 is corrected to 『homework at』 to conform to English writing standards; ② Determiner Error: According to English expression conventions, "a.m." or "p.m." is usually added after the time to indicate morning or afternoon; here, 『a.m.』 needs to be added after the time expression 〈9:30〉 to clearly indicate 9:30 in the morning.

error: On the last
correction: Last
error_type: Preposition Error
error_severity: 2
error_description: Preposition Error: According to English grammar rules, 〈On the〉 is redundant when used with 〈last Saturday〉 in time expressions; English directly uses the time adverbial 『Last Saturday』 to mean “last weekend”, so 〈On the last〉 is changed to 『Last』 to conform to English idiomatic usage rules.
error_sentence: On the last Saturday, at 7:00am, I get up early.
correct_sentence: Last Saturday, at 7:00 am, I got up early.
error: 7:00am
correction: 7:00 am

error_description: Conjunction Error: In the parallel structure, the two noun phrases 〈a pink and lovely shirt〉 and 〈a pair of white shoes〉 both serve as objects of the verb “wear”; they need to be connected by a conjunction, therefore 〈, wear〉 is modified to 『and』 to make the sentence structure conform to the rules for connecting parallel elements in English.
error_sentence: They are beautiful, I like them.
correct_sentence: They are beautiful, and I like them.
correction: and
error_type: Conjunction Error
error_severity: 3

error_type: Conjunction Error
error_severity: 5
error_description: ① Punctuation Error: According to the context, the original sentence 〈Their parents buy some presents〉 and the following text need to be combined into one sentence, so the period 〈.〉 at the end of the sentence is replaced with a comma 『,』 to introduce specific examples; ② Conjunction Error: According to the context, the meaning here is "such as"; the original sentence lacks this conjunction, so 『such as』 is added as an enumerative conjunction to introduce the list of gifts, to fit the context.
error_sentence: some interesting storybooks, some cute dolls and a lot of stationeries.
correct_sentence: Their parents buy some presents for them, such as some interesting storybooks, some cute dolls and a lot of stationery.

error_type: Auxiliary Error
error_severity: 3
error_description: Auxiliary Error: The verb 〈are〉 appears simultaneously with 〈have〉, creating a redundant verb structure; in English, when using the main verb 〈have〉 to express 'possession', an auxiliary verb is not needed, therefore 〈are〉 is deleted to ensure the sentence structure is correct.
error_sentence: So my sister and I are both have blonde.
correct_sentence: So my sister and I both have blonde hair.
correction: hair
error_type: Noun Error
error_severity: 3
error_description: Noun Error: The adjective 〈blonde〉 needs to modify a specific noun; the original sentence lacks the modified noun 『hair』 to clearly describe the hair color, therefore 『hair』 is added after 〈blonde〉 to make the sentence semantically complete and conform to English expression habits.
error_sentence: It's looks so beautiful.
correct_sentence: It looks so beautiful.
error: 's
error_type: Word Redundancy Error

error_sentence: I'm happy. Because I have a good family!
correct_sentence: I'm happy because I have a good family!
error: . Because
correction: because

correction: is
error_type: Sentence Structure Error
error_severity: 3
error_description: Sentence Structure Error: According to English grammar rules, a sentence requires a predicate; the original sentence 〈There a young lady〉 lacks a verb, so 『is』 needs to be added to connect the subject and noun, forming the complete 『There is a young lady』 to comply with English grammar rules.
error_sentence: Linda's mother is trying the shoes.
correct_sentence: Linda's mother is trying on the shoes.
correction: on
error_type: Preposition Error
error_severity: 2
error_description: Preposition Error: According to English expression conventions, the verb 〈trying〉 in the original sentence could be misunderstood as “attempting”, which contradicts the intended meaning; the phrasal verb “try on” means “to put on clothing to see if it fits”, which is a fixed phrase. Missing the preposition 『on』 makes the meaning incomplete, so 『on』 needs to be added after 〈trying〉 to conform to English expression habits and the prompt's requirements.
error_sentence: Linda's father is stayig on the sofa and waiting for Linda' mother.
correct_sentence: Linda's father is staying on the sofa and waiting for Linda's mother.
error: stayig

error_sentence: Linda's father is stayig on the sofa and waiting for Linda' mother.
correct_sentence: Linda's father is staying on the sofa and waiting for Linda's mother.
error: '

error_type: Noun Possessive Error
error_severity: 2
error_description: Noun Possessive Error: According to English grammar rules and the prompt's requirements, the intended meaning here is “Linda's mother”; the phrase 〈Linda' mother〉 in the original sentence needs to be in the possessive form to indicate ownership, so 〈Linda' mother〉 is corrected to 『 Linda's mother』 to fit the context.

error_sentence: He likes blue, but I don't like.
correct_sentence: He likes blue, but I don't like it.
correction: it
error_type: Pronoun Error
error_severity: 3
