1. The original sentence is in the active voice, with the subject "I" performing the action of feeding the chickens. To change it to the passive voice, we use the past participle form of the verb "fed" and add the auxiliary verb "were" before it. The object "the chickens" becomes the subject of the passive sentence. The prepositional phrase "this morning" remains unchanged. 2. The original sentence is in the present perfect tense, indicating an action that started in the past and continues up to the present. To change it to the simple past tense, we replace "have got married" with "got married" and remove the word "since". The phrase "5 years" remains unchanged. 3. The original sentence is in the past simple tense, with the subject "I" performing the action of falling asleep. The conjunction "that" introduces the reason for falling asleep. To change it to a compound sentence, we can use the subordinating conjunction "because" to connect the two clauses. The subject "I" remains the same, and the verb "fell" is unchanged. 4. The original sentence is a complex sentence, with the main clause "it did not delay the traffic" and the subordinate clause "although the weather was bad". To change it to a simple sentence, we can use the prepositional phrase "in spite of" to express the same meaning. The subject "it" and the verb "did not delay" remain unchanged. 5. The original sentence is in the active voice, with the subject "they" performing the action of building a new bridge. To change it to the passive voice, we use the past participle form of the verb "built" and add the auxiliary verb "was" before it. The prepositional phrase "over the river" remains unchanged. 6. The original sentence is in the second conditional form, expressing a hypothetical situation. To change it to the first conditional form, we use the past simple tense in the if-clause and the modal verb "would" before the main verb "feel" in the result clause. The subject "you" remains the same. 7. The original sentence is in the present perfect tense, indicating an action that started in the past and continues up to the present. To change it to the present perfect continuous tense, we replace "last wrote" with "haven't written" and add the preposition "for" before the time period "two months". The phrase "to my pen-pal" remains unchanged. 8. The original sentence is a complex sentence, with the main clause "he can't move that stone" and the subordinate clause "although he is strong". To change it to a simple sentence, we can use the prepositional phrase "in spite of" to express the same meaning. The subject "he" and the verb "can't move" remain unchanged. 9. The original sentence is a direct question, with the subject "she" asking about the location where the brother works. To change it to an indirect question, we use the reporting verb "asked" and the question word "where" becomes an embedded question. The pronoun "your" changes to "my" to match the perspective of the speaker. The verb "work" changes to "worked" to match the past tense of the reporting verb.
