Worksheet for practicing irregular verb forms in present, past, and past participle tenses.

To solve the problem, we need to complete the table by filling in the missing forms of irregular verbs. The table has three columns: Present Tense, Past Tense, and Past Participle. We will identify the correct forms for each verb based on its irregular conjugation.

Here is the completed table with explanations:

Completed Table:

| Present Tense | Past Tense | Past Participle |
|---------------|--------------|-----------------|
| flat | sprang | taken |
| ride | rode | ridden |
| give | gave | given |
| sit | sat | sat |
| enter | entered | entered |
| begin | began | begun |

---

Explanation of Each Verb:

1. Flat:
- This appears to be a typo or an error in the table. The word "flat" is not a verb but an adjective. If this is meant to represent a verb like "flit" (to move quickly), then:
- Present Tense: flit
- Past Tense: flitted
- Past Participle: flitted

However, since the past tense is given as "sprang," it seems there might be a mix-up. Let's assume the intended verb is spring:
- Present Tense: spring
- Past Tense: sprang
- Past Participle: sprung

2. Ride:
- Present Tense: ride
- Past Tense: rode
- Past Participle: ridden

3. Give:
- Present Tense: give
- Past Tense: gave
- Past Participle: given

4. Sit:
- Present Tense: sit
- Past Tense: sat
- Past Participle: sat

5. Enter:
- Present Tense: enter
- Past Tense: entered
- Past Participle: entered

6. Begin:
- Present Tense: begin
- Past Tense: began
- Past Participle: begun

Final Answer:

The completed table is as follows:

| Present Tense | Past Tense | Past Participle |
|---------------|--------------|-----------------|
| spring | sprang | sprung |
| ride | rode | ridden |
| give | gave | given |
| sit | sat | sat |
| enter | entered | entered |
| begin | began | begun |
