Grade 4 - Unit 1 grammar 2 worksheet - Free Printable

Explanation:
Let’s go step by step through each question.

Part 1: Choose the correct answer

1. *Did they ________ the food?*
- “Did” is past simple auxiliary → main verb must be base form (infinitive without *to*).
- Options: cooked (past), cooking (–ing), cook (base), cooks (3rd person singular).
✔ Correct: cook

2. *Did they ________ cleaning the house?*
- Again, after “Did”, we need base verb.
- Options: finishing (–ing), finished (past), finish (base), finishes (3rd person).
✔ Correct: finish

3. *It ________ heavily yesterday.*
- “Yesterday” → past simple tense. Subject “It” (singular), verb must be past form.
- Rain → past = rained
- Options: rain (base), rains (3rd person present), rained (past), raining (–ing)
✔ Correct: rained

4. *The school ________ on a trip to the pyramids 4 weeks ago.*
- “4 weeks ago” → past simple. Subject “The school” (treated as singular noun, but still takes regular past verb).
- Go → past = went
- Options: go (base), went (past), gone (past participle), going (–ing)
✔ Correct: went

5. *They ________ the television in the past.*
- “In the past” → general past time → past simple.
- Invented = past simple of *invent*
- Options: invent (base), inventing (–ing), invented (past), invents (3rd person)
✔ Correct: invented

Part 2: Do as shown

We rewrite the sentence using the word in parentheses — changing tense or adding negation as instructed.

1. *She sold her house last month.* (not)
→ Make it negative in past simple: *She did not sell her house last month.*
(Or short form: *She didn’t sell...*)

2. *She goes to the zoo every week.* (yesterday)
→ Change from present simple to past simple: *She went to the zoo yesterday.*

3. *I (meet) him yesterday.* (correct)
→ Already correct if we use past: *I met him yesterday.*
(Base “meet” → past = met)

4. *Soma buy a new dress every week.* (Last week)
→ First, fix subject-verb agreement: “Soma” (3rd person singular) → *buys* in present. But now change to past with “Last week”:
→ *Soma bought a new dress last week.*

5. *I played the piano a week ago.* (not)
→ Negative past: *I did not play the piano a week ago.*
(Or: *I didn’t play...*)

Now let’s write all final answers clearly.
