To convert the given sentence "She lights the lamp" into passive voice, we need to follow these steps:
- Identify the subject, verb, and object in the active sentence:
- Subject: She
- Verb: lights
- Object: the lamp
- In passive voice, the object of the active sentence becomes the subject. Therefore, "the lamp" will be the subject in the passive voice.
- The verb "lights," which is in the simple present tense, needs to be changed into its passive form. The simple present tense in passive voice is formed using "is/am/are + past participle." Since "the lamp" is singular, we use "is lighted."
- Add the original subject "she" after the verb with the preposition "by" to indicate the doer of the action.
Therefore, the sentence in passive voice is: "The lamp is lighted by her."
Let's analyze the given options to confirm the correct choice:
- The lamp was lighted by her: Incorrect, because "was" indicates past tense, not present.
- The lamp is lighted by her: Correct, because it correctly uses "is lighted" for present tense.
- The lamp has lighted by her: Incorrect, as the form "has lighted" is incorrect for the passive voice structure.
- The lamp is lighted by him: Incorrect, because the sentence changes the doer from "her" to "him."
Therefore, the correct answer is: "The lamp is lighted by her."
