Match present tense verbs with their past tense forms in this grammar worksheet.

Problem Description:

The task is to match each present tense verb on the left with its corresponding past tense verb on the right. This involves understanding how regular and irregular verbs change when used in the past tense.

Solution:

Here is the step-by-step matching of the present tense verbs with their past tense forms:

1. do → did
- The verb "do" is irregular, and its past tense form is "did."

2. go → went
- The verb "go" is irregular, and its past tense form is "went."

3. see → saw
- The verb "see" is irregular, and its past tense form is "saw."

4. eat → ate
- The verb "eat" is irregular, and its past tense form is "ate."

5. watch → watched
- The verb "watch" is regular, and its past tense form is formed by adding "-ed" to the base form.

6. play → played
- The verb "play" is regular, and its past tense form is formed by adding "-ed" to the base form.

7. study → studied
- The verb "study" is regular, and its past tense form is formed by adding "-ed" to the base form.

8. make → made
- The verb "make" is irregular, and its past tense form is "made."

9. cook → cooked
- The verb "cook" is regular, and its past tense form is formed by adding "-ed" to the base form.

10. read → read
- The verb "read" is irregular, and its past tense form is the same as the present tense form, which is "read."

Final Answer:

```
1. do = did
2. go = went
3. see = saw
4. eat = ate
5. watch = watched
6. play = played
7. study = studied
8. make = made
9. cook = cooked
10. read = read
```

Explanation:

- Regular Verbs: Most verbs form their past tense by adding "-ed" to the base form (e.g., "watch" → "watched").
- Irregular Verbs: Some verbs do not follow the regular pattern and have unique past tense forms (e.g., "go" → "went," "see" → "saw").

This exercise helps reinforce the understanding of both regular and irregular verb conjugations in English.
