error_type: Format Error
error_severity: 3
error_description: Format Error: According to English writing conventions, a line break is required between the title and the main text, thus there is a format error here. A 『\n』 needs to be added between the title 〈My next weekend〉 and the beginning of the text 〈Welcome〉 to achieve paragraph separation and comply with English writing conventions.

error_type: Verb Choice Error
error_severity: 3
error_description: Verb Choice Error: According to the original sentence's meaning, the intention is to express 'Welcome to see my weekend plan'. The verb phrase 'welcome to do something' means 'welcome to do something', where 〈my weekend plan〉 corresponds to 'something'. Therefore, the missing 'do' results in an incomplete structure, indicating a verb choice error. The verb phrase 『look at』 needs to be added before 〈my weekend plan〉 to clarify the meaning and complete the structure.

error_sentence: So I'm happy that I'will fast show you.
correct_sentence: So I'm happy that I will show you soon.
error: I'will fast
correction: I will
error_type: Adverb Error
error_severity: 3
error_description: ① Contraction Error: According to English writing conventions, the correct contraction for the simple future tense is the subject followed by “'ll”, and the non-contracted form is the subject followed by the auxiliary verb 'will'. Therefore, 〈I'will〉 should be changed to 『I will』 to comply with English writing conventions; ② Adverb Error: According to the original sentence's meaning, the adverb 〈fast〉 'quickly' does not fit the context and needs to be deleted.

error_sentence: So I'm happy that I'will fast show you.
correct_sentence: So I'm happy that I will show you soon.
correction: soon
error_type: Adverb Error
error_severity: 3
error_description: Adverb Error: According to the original sentence's meaning, it refers to 'I will show you in the near future'. The adverb 'soon' means 'quickly; immediately; shortly'. Therefore, there is a missing adverb error here. The adverb 『soon』 needs to be added after 〈show you〉 to express the meaning of 'shortly' and align with the original sentence's meaning.

error_sentence: On Saturday, I will visit my grandparent with my mom and dad, then I will clean house for helping my grandparent.
correct_sentence: On Saturday, I will visit my grandparents with my mom and dad, and then I will clean the house to help my grandparents.
error: grandparent
correction: grandparents
error_type: Noun Number Error
error_severity: 3
error_description: Noun Number Error: According to English expression habits, 'grandparents' usually refers to two people and requires the plural form of the countable noun. The context does not indicate a need for the singular form for specific reference. Therefore, there is a noun number error here. 〈grandparent〉 needs to be changed to the plural form 『grandparents』 to represent the plural concept and comply with English expression habits.

error_sentence: On Saturday, I will visit my grandparent with my mom and dad, then I will clean house for helping my grandparent.
correct_sentence: On Saturday, I will visit my grandparents with my mom and dad, and then I will clean the house to help my grandparents.
correction: and
error_type: Conjunction Error
error_severity: 3
error_description: Conjunction Error: According to English grammar rules, 'and then' means 'then; next', indicating a clear chronological order. 〈I will visit my grandparents with my mom and dad〉 and 〈then I will〉 contain two independent subject-verb components, and there is a relationship of chronological sequence and semantic progression here. Therefore, there is a conjunction error. 『and』 needs to be added before 〈then〉 to form the phrase 'and then' to comply with English grammar rules and the original sentence's meaning.

error_sentence: On Saturday, I will visit my grandparent with my mom and dad, then I will clean house for helping my grandparent.
correct_sentence: On Saturday, I will visit my grandparents with my mom and dad, and then I will clean the house to help my grandparents.
error: house for helping my grandparent
correction: the house to help my grandparents
error_type: Nonfinite Verb Form Error
error_severity: 4
error_description: ① Determiner Error: According to English grammar rules, the singular countable noun 〈house〉 lacks an article; the definite article 『the』 needs to be added to specify 'the grandparents' house' to comply with English grammar rules; ② Preposition Error: According to English grammar rules, the 'to do' infinitive expresses purpose and can serve as a post-modifier. Here, explaining the purpose of 'clean the house' requires the 'to do' infinitive, so the preposition 〈for〉 should be changed to 『to』 to comply with grammar rules and the original sentence's meaning; ③ Nonfinite Verb Form Error: The gerund form 〈helping〉 should be changed to 『help』 to form a complete infinitive structure expressing purpose, complying with grammar rules and the original sentence's meaning.

error_sentence: On Sunday, I will play computer game that can hepl me have a perfect rest.
correct_sentence: On Sunday, I will play computer games that can help me have a perfect rest.
error: game
correction: games
error_type: Noun Number Error
error_severity: 3
error_description: Noun Number Error: According to English grammar rules, the plural form of a countable noun is used for generic reference. Therefore, there is a noun number error here. The singular form 〈computer game〉 needs to be changed to the plural form 『computer games』 for generic reference to comply with English grammar rules.

error_sentence: On Sunday, I will play computer game that can hepl me have a perfect rest.
correct_sentence: On Sunday, I will play computer games that can help me have a perfect rest.

error_type: Spelling Error
error_severity: 2

error_sentence: When it's afternoon, I will play football with my friend, it'e good for my healthy.
correct_sentence: When it's afternoon, I will play football with my friend. It's good for my health.
error: , it'e
correction: . It's
error_type: Punctuation Error
error_severity: 3
error_description: ① Punctuation Error: The original sentences 〈I will play football with my friend〉 and 〈it'e good ...〉 contain independent subject-verb structures and can stand alone as sentences. Therefore, 〈, it'e...〉 needs to be changed to 〈. It'e...〉 to form two separate sentences; ② Spelling Error: According to English writing conventions, the correct contraction for 'it is' is 'it's'. 〈It'e〉 needs to be changed to 『It's』 to comply with English writing conventions.

error_sentence: When it's afternoon, I will play football with my friend, it'e good for my healthy.
correct_sentence: It's good for my health.
error: healthy
correction: health
error_type: PoS Confusion Error
error_severity: 2
error_description: PoS Confusion Error: According to the original sentence's meaning, the intention is to express 'good for my health'. The adjective 〈healthy〉 is mistakenly used as a noun here, indicating a part-of-speech confusion error. The adjective 〈healthy〉 needs to be changed to the noun 『health』 to align with the original sentence's meaning.
