error_type: Relative Word Error
error_severity: 3
error_description: ① Relative Word Error: According to English grammar rules, 〈whose〉 is used to indicate possession, while here a relative pronoun 『who』 is needed to introduce a non-restrictive relative clause modifying 〈L and W〉; 〈whose〉 should be changed to 『, who』; ② Punctuation Error: According to English writing conventions, a non-restrictive relative clause needs to be set off by commas; the original sentence lacks a comma between 〈W whose〉, so a 『,』 should be added after 〈W〉 to make the sentence structure clear.

correction: ,
error_type: Punctuation Error
error_severity: 2

error_sentence: During the climbing, we met Mr. and Mrs. Smith who had missed handbag.
correct_sentence: During the climb, we met Mr. and Mrs. Smith, who had lost a handbag.

error_type: Noun Error
error_severity: 3
error_description: Noun Error: According to English grammar rules, 〈climbing〉 is a gerund form; here, the noun 『climb』 is needed to represent the activity of climbing itself, fitting the prepositional phrase 〈during the...〉. The meaning of 〈climbing〉 in the original sentence is inappropriate; 〈climbing〉 should be changed to 『climb』 to correctly express the type of activity.
error_sentence: During the climbing, we met Mr. and Mrs. Smith who had missed handbag.
correct_sentence: During the climb, we met Mr. and Mrs. Smith, who had lost a handbag.
correction: ,
error_type: Punctuation Error
error_severity: 2
error_description: Punctuation Error: According to English grammar rules, the non-restrictive relative clause 〈who had lost a handbag〉 needs to be separated from the main clause by a comma; the original sentence lacks the necessary comma between 〈Smith who〉, so a 『,』 should be added after 〈Smith〉 to clearly separate the main clause and the subordinate clause, conforming to English writing conventions.
error_sentence: During the climbing, we met Mr. and Mrs. Smith who had missed handbag.
correct_sentence: During the climb, we met Mr. and Mrs. Smith, who had lost a handbag.
error: missed
correction: lost a
error_type: Verb Choice Error
error_severity: 3
error_description: ① Verb Choice Error: According to the sentence meaning, the intention is to express "lost," whereas 〈missed〉 means "failed to catch/experience," which does not fit the context; it should be changed to 『lost』 to correctly express the state of the handbag being lost; ② Determiner Error: According to English grammar rules, when the countable noun 〈handbag〉 is singular, it requires an indefinite article 『a』 before it; the original sentence is missing it, so 『a』 should be added to modify 〈handbag〉.
error_sentence: The smiths were happy that found the handbag and they thanked us as well.

correct_sentence: The Smiths were happy that we found the handbag and they thanked us as well.

error: smiths
correction: Smiths
error_type: Case Error
error_severity: 1
error_description: Case Error: According to English writing conventions, the surname 〈Smith〉 as a proper noun needs to be capitalized; the plural form 『Smiths』 refers to Mr. and Mrs. Smith. In the original sentence, the first letter of 〈smiths〉 is not capitalized; 〈smiths〉 should be changed to 『Smiths』 to conform to proper noun writing conventions.
error_sentence: The smiths were happy that found the handbag and they thanked us as well.

correct_sentence: The Smiths were happy that we found the handbag and they thanked us as well.

correction: we
error_type: Sentence Structure Error
error_severity: 3
error_description: Sentence Structure Error: According to English grammar rules, the object clause 〈that found the handbag〉 is missing a subject, leading to an incomplete sentence structure. Adding 『we』 makes the clause structure complete, forming the correct sentence pattern 『that we found...』, ensuring clear and complete expression of meaning.
error_sentence: I think we should help everyone that in trouble.
correct_sentence: I think we should help everyone in trouble.
error: that
error_type: Word Redundancy Error
error_severity: 3
error_description: Word Redundancy Error: According to English grammar rules, "in trouble" here is a prepositional phrase directly modifying "everyone," and does not require a relative pronoun to introduce a clause. The use of 〈that〉 in the original sentence is redundant; 〈that〉 should be deleted to make the sentence concise and grammatically correct.
error_sentence: We also should help foreigner because they may know little Chinese.
correct_sentence: We should also help foreigners because they may know little Chinese.
error: also should help foreigner
correction: should also help foreigners
error_type: Word Order Error
error_severity: 3
error_description: ① Word Order Error: According to English grammar rules, the frequency adverb 〈also〉 should be placed after the modal verb 〈should〉; the order in the original sentence 〈also should〉 is incorrect and should be adjusted to 『should also』; ② Noun Number Error: According to the sentence meaning and the pronoun 〈they〉, this refers to foreigners as a group; the noun 〈foreigner〉 needs to be in the plural form 『foreigners』 to maintain number agreement.
error_sentence: When we give them a favor, we will fell happy and give others a good memory.
correct_sentence: When we do them a favor, we will feel happy and give others a good memory.
error: give
correction: do
error_type: Verb Choice Error
error_severity: 3
error_description: Verb Choice Error: According to English fixed collocation rules, 〈do someone a favor〉 means "to help someone"; the verb 『do』 is required here. The verb 〈give〉 in the original sentence does not fit this fixed phrase and should be changed to 『do』.
error_sentence: When we give them a favor, we will fell happy and give others a good memory.
correct_sentence: When we do them a favor, we will feel happy and give others a good memory.
error: fell
correction: feel
error_type: Verb Choice Error
error_severity: 3
error_description: Verb Choice Error: According to the sentence meaning, the intention is to express "feel"; 〈fell〉 is the past tense of the verb 〈fall〉 (to drop), which does not fit the context. 〈fell〉 should be changed to 『feel』 (to experience an emotion or sensation) to accurately express the intended meaning.
error_sentence: Let us help others together
correct_sentence: Let us help others together.
correction: .
error_type: Punctuation Error
error_severity: 2
error_description: Punctuation Error: According to English writing conventions, a period 『.』 needs to be added at the end of a sentence to ensure completeness and conform to writing rules. The original sentence 〈Let us help others together〉 is missing a period at the end; a 『.』 should be added.
