Learn English – Passive Voice of this sentence

Number (2) is fine, correct and natural.

Number (3) should say, 'Some money was given to her.'

Number (5) is close, but the 'to' should be replaced with 'by him': 'She was given some money by him.' However, you could omit both so it's exactly the same as Number (2).

Number (6) is fine, correct and natural.

As for the best way to get this into the passive voice, I would say 'She was given some money by him' is your best option.

That's an interesting question. Normally, a switch to the passive voice allows the subject in the active voice to be dropped. In the case of your example, this may give rise to an unwanted inference.

If the original used courted instead of married, you could drop the subject and change the tense of courted to produce

• Lucy was courted four years ago.

However, doing the same with married to produce

• Lucy was married four years ago.

gives the impression that Lucy is no longer married.

This is the case with other verbs of the same type. That is, where using the past perfect looks like applying an adjective.

Marry verb 1 Join in marriage. ‘I was married in church’ ‘my sister got married to a Welshman’ - ODO

Married adjective 1.1 (of a person) having a husband or wife. ‘a happily married man’ - ODO

You have the same phenomena with the word employ. Compare:

• IBM employed him last year.
• He was employed last year.

The way to get around it is to use the form in the second dictionary example above: got married:

• Lucy got married four years ago.
