The test is coming. But there was something unhappy.
My roommate is a football fan. He likes watching football games. That day, he was watching football games on the Internet. He was very excited and cheered for the players of his favourite team when he was watching the game. I was going over my lessons that night. But his sound and the sound of the game were too loud. I couldn't focus on my book carefully so I was very angry. I told him to turn down the sound. He was very sorry. He turned it down and said sorry to me. So I could go over my lessons, and he could enjoy himself. Both of us were happy.
We had a good night. To take a step backward can actually make life better, I think.

error_description: ① Noun Error: According to the original sentence's meaning, it intends to express "the exam is coming soon," and the word for "考试" (exam) is "test"; therefore, 〈text〉 needs to be changed to 『test』 to match the original meaning.; ② Spelling Error: According to English spelling rules, the present participle -ing form of the verb "come" requires "dropping the e and adding ing," without doubling the "m." Therefore, the incorrect spelling 〈comming〉 needs to be changed to 『coming』 to conform to spelling rules.
error_sentence: But there are something unhappy.

correct_sentence: But there was something unhappy.

error: are
correction: was
error_type: Subject-Verb Agreement Error
error_severity: 3
error_description: Subject-Verb Agreement Error: According to English grammar rules, in a "there be" sentence structure, the singular or plural form of the be-verb is determined by the singular or plural form of the subject that follows it. Here, the subject is the uncountable noun "something," so the be-verb needs to be in the singular form. Therefore, 〈are〉 needs to be changed to the simple past singular form 『was』 to conform to the context's tense and the principle of subject-verb agreement.

error_type: Determiner Error
error_severity: 4
error_description: ① Preposition Error: According to English grammar rules, the phrasal verb "cheer for somebody" means "to cheer for someone." Here, 〈players of his favourite team〉 is equivalent to "somebody"; therefore, the preposition 『for』 needs to be added after the verb 〈cheered〉 to form a complete phrase that matches the original meaning and grammatical rules.; ② Determiner Error: According to the original sentence's meaning, it specifically refers to "the players of his favourite team"; the definite article 『the』 needs to be added before the specific object 〈players of his favourite team〉 to indicate specificity and conform to grammatical rules.
error_sentence: But his sound and the sound of the game was too big.
correct_sentence: But his sound and the sound of the game were too loud.
error: was too big
correction: were too loud
error_type: Subject-Verb Agreement Error
error_severity: 5
error_description: ① Subject-Verb Agreement Error: According to the context, the subject 〈the sound〉 is singular, therefore the verb needs to be in singular form, it is necessary to change 〈were〉 to 『was』 to conform to the principle of subject-verb agreement.; ② Adjective Error: According to the original sentence's meaning, it intends to express "the game's sound was too loud." In English, "loud" is used to describe a high volume of sound, not "big"; therefore, 〈big〉 should be changed to 『loud』 to better conform to English expression habits.
error_sentence: I couldn't look my book carefully
correct_sentence: I couldn't focus on my book carefully
error: look
correction: focus on
error_type: Verb Choice Error
error_severity: 3
error_description: Verb Choice Error: According to the original sentence's meaning, it intends to express "I couldn't concentrate on reading my book." According to English expression habits, only the main verb "concentrate" should be kept here, and there is no need to repeat the verb "look" to avoid word redundancy. Therefore, the misused verb 〈look〉 needs to be changed to the phrasal verb 『focus on』 to match the original meaning and English expression habits.

correct_sentence: so I was very angry.
error: ungry
correction: angry
error_type: Spelling Error
error_severity: 2
error_description: Spelling Error: According to English word spelling rules, the correct spelling of the adjective "生气的" (angry) is "angry." The incorrect spelling 〈ungry〉 needs to be changed to 『angry』 to conform to word spelling rules and the original sentence's meaning.
error_sentence: I told him that turned down the sound.
correct_sentence: I told him to turn down the sound.
error: that turned
correction: to turn
error_type: Nonfinite Verb Form Error
error_severity: 3
error_description: Nonfinite Verb Form Error: According to the original sentence's meaning, it intends to express "I told him to turn down the volume a bit." The English phrasal verb "tell somebody to do something" means "to tell someone to do something"; here, 〈the sound〉 is equivalent to "something." Therefore, 〈that turned〉 needs to be changed to the infinitive form 『to turn』 to conform to English grammar rules and the original sentence's meaning.
error_sentence: So I could go over my lessons and he could enjoy himself.
correct_sentence: So I could go over my lessons, and he could enjoy himself.
correction: ,
error_type: Punctuation Error
error_severity: 2
error_description: Punctuation Error: According to English syntax rules, two coordinate clauses 〈So I could go over my lessons〉 and 〈he could enjoy himself〉 in the same compound sentence need to be separated by a comma and a conjunction to avoid a run-on sentence. Therefore, 『, 』 needs to be added before the coordinating conjunction 〈and〉 to conform to syntax rules.
error_sentence: We spent a good night.
correct_sentence: We had a good night.
error: spent
correction: had
error_type: Verb Choice Error
error_severity: 3
error_description: Verb Choice Error: According to English expression habits, in "had a good night," the verb "度过" (spent/had) should be "have." The word 〈spent〉 in the original sentence means "to spend (time, money, etc.)," which does not fit the original sentence's meaning. Therefore, 〈spent〉 needs to be changed to 『had』 to match the original meaning and English expression habits.
error_sentence: To make a step backward can actually live better,I thing.
correct_sentence: To take a step backward can actually make life better, I think.
error: make
correction: take
error_type: Verb Choice Error
error_severity: 3
error_description: Verb Choice Error: According to the original sentence's meaning, it intends to express "take a step backward." The fixed English expression for "后退一步" is "take a step back/backward." Therefore, the misused verb 〈make〉 needs to be changed to 『take』 to conform to the original meaning and English expression norms.
error_sentence: To make a step backward can actually live better,I thing.
correct_sentence: To take a step backward can actually make life better, I think.
error: live
correction: make life
error_type: Verb Choice Error
error_severity: 3
error_description: Verb Choice Error: According to the original sentence's meaning, it intends to express "taking a step backward can actually make life better." The subject of 〈live〉 in the original sentence should be a person, but the subject of this sentence is the infinitive phrase 〈To take a step backward〉; therefore, 〈live〉 cannot function as the main verb. The verb 〈live〉 needs to be changed to the verb-object structure 『make life』 to conform to English grammar rules and the original sentence's meaning.
error_sentence: To make a step backward can actually live better,I thing.
correct_sentence: To take a step backward can actually make life better, I think.
error: thing
correction: think
error_type: Spelling Error
error_severity: 2
error_description: Spelling Error: According to the original sentence's meaning, "I think" here functions as a parenthetical phrase meaning "I believe/suppose." The correct spelling of the word "认为" (think) is "think"; therefore, 〈thing〉 needs to be changed to 『think』 to conform to the original meaning and word spelling rules.
