Level B. Rewrite the sentences in the passive.

1. A doctor has examined me and told me to rest at home. – I had been examined by a doctor and was told to rest at home.

Explanation: In this sentence, the subject "a doctor" performs the action "examined me" in the active voice. To transform it into the passive voice, we need to make the object "me" the subject and use the past participle form of the verb "examine," which is "been examined." We also need to add the preposition "by" to indicate the doer of the action, which is "a doctor."

2. It was the 19th century that they invented anesthetics. – Anesthetics were invented by them in the 19th century.

Explanation: In this sentence, the subject "they" performs the action "invented anesthetics" in the active voice. To transform it into the passive voice, we need to make the object "anesthetics" the subject and use the past participle form of the verb "invent," which is "were invented." We also need to add the preposition "by" to indicate the doer of the action, which is "them."

3. Scientists are making more advances in medicine every year. - More advances in medicine are being made by scientists every year.

Explanation: In this sentence, the subject "scientists" performs the action "are making more advances in medicine" in the active voice. To transform it into the passive voice, we need to make the object "more advances in medicine" the subject and use the present participle form of the verb "make," which is "are being made." We also need to add the preposition "by" to indicate the doer of the action, which is "scientists."

4. Kazimierz Funk, a Polish scientist, discovered the fact that vitamins could cure many diseases. - The fact that vitamins could cure many diseases was discovered by Kazimierz Funk, a Polish scientist.

Explanation: In this sentence, the subject "Kazimierz Funk, a Polish scientist" performs the action "discovered the fact that vitamins could cure many diseases" in the active voice. To transform it into the passive voice, we need to make the object "the fact that vitamins could cure many diseases" the subject and use the past participle form of the verb "discover," which is "was discovered." We also need to add the preposition "by" to indicate the doer of the action, which is "Kazimierz Funk, a Polish scientist."

5. They will stitch the wound now and remove the stitches next week. - The wound will be stitched now and the stitches will be removed next week.

Explanation: In this sentence, the subject "they" performs the actions "will stitch the wound now" and "will remove the stitches next week" in the active voice. To transform it into the passive voice, we need to make the objects "the wound" and "the stitches" the subjects and use the future tense of the verb "will" in the passive form. Therefore, it becomes "The wound will be stitched now" and "The stitches will be removed next week."
