How do we form the present tense in passive voice?

To form the present tense in passive voice, we use the auxiliary verb "to be" followed by the past participle of the main verb. The form of the auxiliary verb "to be" depends on the subject of the sentence. Here is the general structure:

Subject + auxiliary verb "to be" (am, is, are) + past participle of the main verb

Let's take a closer look at the different forms of the auxiliary verb "to be" in the present tense:

1. For singular subjects:
- I am + past participle
- You are + past participle
- He/She/It is + past participle

Example: The cake is baked by my sister.

2. For plural subjects:
- We are + past participle
- You are + past participle
- They are + past participle

Example: The books are read by the students.

It is important to note that the past participle of regular verbs is formed by adding "-ed" to the base form of the verb. However, irregular verbs have their own unique past participle forms.

Here are some additional examples of sentences in the present tense passive voice:

- The letter is written by John.
- The car is repaired by the mechanic.
- The house is cleaned by the maid.
- The movie is watched by millions of people.

In summary, the present tense in passive voice is formed by using the auxiliary verb "to be" followed by the past participle of the main verb. The form of the auxiliary verb depends on the subject of the sentence.
