error_type: Determiner Error
error_severity: 2
error_description: Determiner Error: According to English grammar rules, the job title 〈president〉 when used as a predicative usually does not take an article, so the incorrect determiner 『the』 is deleted. However, 『Students' Union』 as a specific organization name requires a definite article, thus it is adjusted to the correct expression 『president of the Students' Union』.
error_sentence: My name is H.This weekend,I will organize some students to take part in an outdoor activity.
correct_sentence: My name is H. This weekend, I will organize some students to take part in an outdoor activity.
error: H.This
correction: H. This
error_type: Space Error
error_severity: 2
error_description: Space Error: According to English writing conventions, a space is required after end-of-sentence punctuation (such as a period or comma), so the incorrect format 〈H.This〉 is corrected to 『H. This』.

error: could
correction: can
error_type: Auxiliary Error
error_severity: 2

correct_sentence: Studying at school puts more and more pressure on us, so an outdoor activity will help us get close to nature and relax.

error_severity: 3
error_description: Verb Choice Error: The meaning here should be 'to exert pressure', the correct verb is 『puts』 not the incorrect verb 〈laies〉, the correct spelling is 『lays』 but it is still not applicable, so it is corrected to 『puts more and more pressure on us』, indicating the action of exerting pressure.

error_type: Noun Error

error_type: Nonfinite Verb Form Error
error_severity: 1
error_description: ① Nonfinite Verb Form Error: According to the principle of parallel structure, the verb 〈relaxed〉 needs to be changed to the infinitive 『relax』 to be consistent with the preceding 『get close to nature』, thus corrected to 『help us get close to nature and relax』; ② Pronoun Error: The pronoun 〈ourself〉 is a singular reflexive pronoun, which does not match the plural subject 〈us〉, so it is changed to the plural form 『ourselves』 to maintain number agreement.
