Assignment Overview

Time to flex your GRAMMAR POWER. You'll catch shifting verb tenses, missing commas, wrong past-participle forms, and tricky correlative pairs, then rewrite each sentence so it reads sharp.

Phase 1: Identify the Error
1
The students finished their test and then they are walking to lunch.
  1. Verb Tense Shift ✓ Correct
  2. Missing Comma
  3. Wrong Verb Form
  4. No Error
Why: The sentence starts in past tense (finished) but shifts to present tense (are walking). It should stay in past tense: 'walked to lunch.'
2
Maria loved painting, and every weekend she goes to the art studio.
  1. Missing Comma
  2. Verb Tense Shift ✓ Correct
  3. Conjunction Error
  4. No Error
Why: The sentence shifts from past tense (loved) to present tense (goes). Both should match.
3
The dog chased the ball across the yard and catches it near the fence.
  1. Wrong Verb Form
  2. No Error
  3. Verb Tense Shift ✓ Correct
  4. Missing Comma
Why: The sentence starts in past (chased) but shifts to present (catches). It should say 'caught it near the fence.'
4
We need to buy apples bananas and oranges from the store.
  1. Verb Tense Shift
  2. Missing Comma ✓ Correct
  3. Wrong Verb Form
  4. No Error
Why: Items in a series need commas: 'apples, bananas, and oranges.' This is called a serial comma or Oxford comma.
5
After the long hike the campers were exhausted.
  1. No Error
  2. Verb Tense Shift
  3. Missing Comma ✓ Correct
  4. Conjunction Error
Why: An introductory phrase needs a comma after it: 'After the long hike, the campers were exhausted.'
6
Yes I would love to go to the park today.
  1. Wrong Verb Form
  2. Missing Comma ✓ Correct
  3. Verb Tense Shift
  4. No Error
Why: The word 'yes' at the start of a sentence needs a comma: 'Yes, I would love to go to the park today.'
7
During the thunderstorm the power went out in our neighborhood.
  1. Missing Comma ✓ Correct
  2. Conjunction Error
  3. No Error
  4. Verb Tense Shift
Why: The introductory phrase 'During the thunderstorm' needs a comma after it.
8
I have went to that museum three times already.
  1. Verb Tense Shift
  2. Missing Comma
  3. Wrong Verb Form ✓ Correct
  4. No Error
Why: With 'have,' you need the past participle: 'I have gone to that museum.' The word 'went' is simple past.
9
By the time we arrived, the movie had already began.
  1. No Error
  2. Wrong Verb Form ✓ Correct
  3. Missing Comma

  1. Missing Comma
  2. Verb Tense Shift
  3. Wrong Verb Form ✓ Correct
  4. No Error

  1. Missing Comma

  1. Verb Tense Shift

  1. Missing Comma

  3. Wrong Verb Form
  4. Conjunction Error
