Simple Present Tense Worksheet, Adding ‘S’ to Verbs

Understanding the Simple Present Tense in English

The Simple Present Tense is one of the most essential tenses in English. It is widely used in daily conversations and written communication. This tense helps us describe habits, routines, fixed schedules, and facts that are always true.

We also use the Simple Present Tense for general truths and situations that do not change over time.

Examples:

  • Water freezes at zero degrees.

  • Mobile phones need electricity to work.

Because these facts are always true, the Simple Present Tense is the correct choice.

Basic Sentence Structure in English

English sentences usually follow a simple and clear order:

Subject + Verb + Object

In affirmative sentences, the verb is used in its base form, except when the subject is he, she, or it.

Affirmative (Positive) Sentences

For most subjects, the verb stays in its original form:

I / You / We / They + base verb + object

Examples:

  • I check my emails every morning.

  • They visit their grandparents on Sundays.

When the subject is he, she, or it, we add “-s” or “-es” to the verb:

He / She / It + verb + -s/-es + object

Examples:

  • He drives to work early.

  • It makes a strange noise at night.

Negative Sentences in the Simple Present Tense

Negative sentences are formed using do not (don’t) or does not (doesn’t), depending on the subject.

I / You / We / They + do not (don’t) + base verb

Example:

  • We do not trust unknown websites.

He / She / It + does not (doesn’t) + base verb

Example:

  • She does not enjoy crowded places.

Remember: when we use do/does, the verb stays in its base form. The “-s” ending disappears.

Question Forms in the Simple Present Tense

To ask questions, we place do or does at the beginning of the sentence.

Do + I / You / We / They + base verb + object?

Example:

  • Do they store files in the cloud?

Does + He / She / It + base verb + object?

Example:

  • Does he follow the news regularly?

As with negative sentences, the verb does not take the “-s” ending.

Common Mistakes to Avoid

Even though the Simple Present Tense is basic, learners often repeat the same mistakes.

1. Forgetting the “-s” with He/She/It

Many learners forget to add “-s” when the subject is singular.

Incorrect: She work late on weekdays.
Correct: She works late on weekdays.

2. Using “-s” in Questions or Negatives

Adding “-s” after using does is incorrect.

Incorrect: Does he needs help?
Correct: Does he need help?

3. Misusing the Verb “To Be”

The verb to be (am / is / are) does not follow the same rules as other verbs.

Examples:

  • The room is quiet.

  • Are the keys on the table?

When another verb is present, “to be” is not needed.

4. Breaking Sentence Order

English relies heavily on word order. Mixing up the subject, verb, or auxiliary can lead to errors.

Incorrect: Always she drinks tea.
Correct: She always drinks tea.
