Correcting the Verb Tense worksheet for grammar practice.

To solve this worksheet, we need to change the verb in each sentence so that it matches the time frame (tense) of the whole sentence.

Here is the step-by-step breakdown for each question:

1. Sentence: "Annie draws a picture and colored it."
* Clue: The word "colored" is in the past tense. This means the whole sentence happened in the past.
* Action: Change "draws" (present) to its past tense form. The past tense of "draw" is "drew".
* Result: Annie drew a picture...

2. Sentence: "After an hour, Sam will go to the store and buys milk."
* Clue: The phrase "will go" tells us this is happening in the future.
* Action: When using "will," the next verb stays in its base form. We need to match "will go." So, we use "will buy" or just the base form if "will" is implied for both verbs. Since "will" is already there for "go," we just need the base form "buy" to match the future structure.
* Result: ...Sam will go to the store and buy milk.

3. Sentence: "The elephant walked to the stream, drank some water, and quench its thirst."
* Clue: The words "walked" and "drank" are in the past tense.
* Action: Change "quench" to the past tense. The past tense of "quench" is "quenched".
* Result: ...and quenched its thirst.

4. Sentence: "Willy broke the wand and pronounces it correctly."
* Clue: The word "broke" is in the past tense.
* Action: Change "pronounces" (present) to the past tense. The past tense of "pronounce" is "pronounced".
* Result: ...and pronounced it correctly.

5. Sentence: "Sandy went to Detroit and attend the conference."
* Clue: The word "went" is in the past tense.
* Action: Change "attend" to the past tense. The past tense of "attend" is "attended".
* Result: ...and attended the conference.

6. Sentence: "Owen gulps the door and slammed it shut."
* Clue: The word "slammed" is in the past tense.
* Action: Change "gulps" (present) to the past tense. The past tense of "gulp" is "gulped". *(Note: "Gulping a door" is a strange action, but grammatically, we just fix the tense!)*
* Result: Owen gulped the door...

7. Sentence: "The sparrow gathered twigs and building a nest."
* Clue: The word "gathered" is in the past tense.
* Action: Change "building" (which is present continuous/participle) to the simple past tense to match "gathered." The past tense of "build" is "built".
* Result: ...and built a nest.

8. Sentence: "They had already visited the store and buying the car."
* Clue: The phrase "had already visited" is in the past perfect tense.
* Action: To match "had visited," we need the past participle of "buy." The past participle of "buy" is "bought." So it becomes "had... bought."
* Result: ...and bought the car.

Final Answer:
1. drew
2. buy
3. quenched
4. pronounced
5. attended
6. gulped
7. built
