Grammar Editing: Agreement, Voice, and Tense Under Time Pressure
A grammar-editing task gives this paragraph: 'Each of the students in the science club have submitted a project. The best ones was displayed in the hall. Our teacher, along with two judges, were impressed. She said that the models should be improve before the exhibition. We have began planning the next step.' The instruction is: 'Rewrite the paragraph correcting only grammatical errors. Do not change the meaning.' A student submits: 'Each of the students have submitted... The best ones were displayed... Our teacher, along with two judges, was impressed... the models should improve... We have begun...' The teacher says two corrections are still wrong and one correct change has created a meaning shift. The student cannot see why 'along with two judges' matters. The class has revised subject-verb agreement, passive voice, and present perfect tense, but the student mixes them under time pressure.
1. Correct the subject-verb agreement errors in sentences 1 and 3. Explain why each correction is needed.

Sentence 1: 'Each of the students in the science club has submitted a project.' The subject is 'Each', which is singular, even though 'students' is plural; the prepositional phrase 'of the students' does not change the subject.
Sentence 3: 'Our teacher, along with two judges, was impressed.' The subject is 'Our teacher'; 'along with two judges' is a parenthetical phrase, not part of a compound subject. So the verb is singular 'was'. The student's 'have' and 'were' follow the nearest noun, which is the trap.
2. The student changed 'should be improve' to 'should improve'. Is that acceptable? Explain the voice issue and give the correct form.

No. 'The models should improve' changes meaning: it says the models themselves will get better. The original intended passive: someone should improve the models. After a modal, the passive is 'should be + past participle': 'should be improved'.
The student removed 'be' but did not change 'improve' to 'improved', so the sentence became active and illogical. Correct: 'She said that the models should be improved before the exhibition.'
3. Explain the tense error in 'We have began' and provide the corrected sentence.
Read the worked answer
'Have began' is wrong because the present perfect is formed with 'have/has + past participle'. The past participle of 'begin' is 'begun', not the past simple 'began'.
Correct: 'We have begun planning the next step.' The tense is present perfect because the planning started recently and is relevant now. If the sentence meant a finished past action, 'We began planning' would also be grammatical, but it would change the time focus.
