Answer 2

Answer:

Changing into active voice from passive voice and vice versa follows some rules.  

Active Voice : "Subject + verb + Object + Adverb "

Passive Voice: "Object + Changed form of verb + by + Subject + Adverb "

1. Sand fills the jar.

Here, in active form, “am/is/are + past participle – is filled” has changed to “Simple present tense - fills”.

2. Mary enjoys reading

Here, in active form, “am/is/are + past participle – is enjoyed” has changed to “Simple present tense - enjoys”.

3. Fire destroyed the town.

Here, in active form, “was/were + past participle – was destroyed” has changed to “Simple past tense - destroyed”.

4. John will clean the room every Saturday.

Here, in active form, “will/shall + be + past participle – will be cleaned” has changed to “Simple future tense – will clean”.

5. Sara ate the cheese.

Here, in active form, “was/were + past participle – was eaten” has changed to “Simple past tense - ate”.
