error_type: Verb Choice Error
error_severity: 3

error_sentence: People have more time to play.
correct_sentence: People will have more time to play.
correction: will
error_type: Verb Tense Error
error_severity: 3
error_description: Verb Tense Error: Based on the context, the future tense is needed here; the original sentence mistakenly used the simple present tense, so the predicate verb 〈have〉 needs to be changed to the future tense form 『will have』 to conform to tense consistency.

error_sentence: Space shuttle can bring people to planets far from the earth.
correct_sentence: Space shuttles can bring people to planets far from the earth.
error: shuttle
correction: shuttles
error_type: Noun Number Error

error_type: Verb Tense Error
error_severity: 3

error_sentence: They will be more delicious and healthy than they are now.

correct_sentence: They will be more delicious and healthier than they are now.

error: healthy
correction: healthier
error_type: Adjective Error
error_severity: 2
error_description: Adjective Error: Based on the sentence meaning, it is intended to express 'healthier', so the comparative degree should be used; therefore, the positive degree 〈healthy〉 needs to be changed to the comparative degree 『healthier』 to conform to grammar and match the preceding phrase 〈more delicious〉.

error_sentence: Every one of us can afford to pay.

correct_sentence: Every one of us can afford them.

error: to pay
correction: them
error_type: Pronoun Error
error_severity: 2
error_description: Pronoun Error: Based on the sentence meaning, the pronoun 『them』 is needed here to refer to the food mentioned earlier, not the phrase 〈to pay〉, therefore it is changed to 『them』 to ensure correct pronoun usage.

error_sentence: Future life will be better than it is now, I believe that the future of the world will be full of happiness.
correct_sentence: Future life will be better than it is now.

error_type: Punctuation Error
error_severity: 1
error_description: Punctuation Error: According to English writing conventions, the two independent clauses in the sentence, 〈Future life will be better than it is now〉 and 〈I believe that the future of the world will be full of happiness〉, need to be separated by a period, not a comma; therefore, 〈,〉 is changed to 『.』 to conform to punctuation rules.
