Understanding Active and Passive Voice Conversion

The question asks us to convert a sentence from active voice to passive voice. The given sentence is: "We are organising the charity function tomorrow."

Identifying the Voice and Tense

The original sentence "We are organising the charity function tomorrow" is in the active voice. The subject "We" performs the action "are organising". The tense is the present continuous tense (subject + am/is/are + verb-ing).

Converting Present Continuous Active to Passive

To convert a sentence from active voice (present continuous) to passive voice, we follow a specific structure:

Active: Subject + am/is/are + verb-ing + Object + (optional time/place information)

Passive: Object + am/is/are + being + past participle of the verb + (by + Subject - usually optional) + (optional time/place information)

In the given sentence:

• Subject: We
• Verb phrase: are organising
• Object: the charity function
• Time information: tomorrow

Applying the passive voice structure:

• New subject (original object): The charity function
• Verb phrase: Since "The charity function" is singular, we use "is". The passive form for present continuous is "is being" + past participle. The past participle of "organising" is "organised". So the verb phrase becomes "is being organised".
• Original subject ("We") can be omitted or included as "by us". In the given options, it is omitted.
• Time information: tomorrow (remains in place).

So, the passive voice sentence is "The charity function is being organised tomorrow."

Analysing the Options

Let's examine each option based on the correct passive voice structure for the present continuous tense:

1. The charity function is been organised tomorrow.
   This option uses "is been", which is incorrect for the present continuous passive. The correct form is "is being".
2. The charity function is being organised tomorrow.
   This option follows the correct structure: Object ("The charity function") + is + being + past participle ("organised") + time ("tomorrow").
3. The charity function is being organise tomorrow.
   This option uses the base form "organise" instead of the past participle "organised". This is incorrect.
4. The charity function is organised tomorrow.
   This option uses the structure for the simple present passive (is/am/are + past participle), not the present continuous passive.

Based on the analysis, only option 2 correctly converts the sentence into the passive voice using the present continuous tense structure.

Additional Information: Purpose of Passive Voice

The passive voice is often used when:

• The action is more important than the doer of the action.
• The doer of the action (subject in active voice) is unknown, unimportant, or obvious from the context.
• We want to avoid mentioning the doer of the action.

In this sentence, "The charity function is being organised tomorrow," the focus is on the event ("the charity function") and its status (being organised), rather than specifically on who is doing the organising ("We").
