Answer 2

Answer:

English has active and passive voices. The active voice tells you what the subject of a sentence does. The passive voice creates a new subject. The active voice is more common than the passive. Using the passive voice changes the focus of your sentence. You can use a passive when you want to emphasise the action itself, when the reader does not need to know who did an action, or when you do not want to emphasise who did an action (as long as you leave out the word by and the name, e.g. by Ching).

Only transitive verbs (verbs which take a direct object) can be made passive. (Examples of transitive verbs are break, buy, make.) Intransitive verbs do not take an object and cannot be made passive. (Examples of intransitive verbs are cry, laugh, go.)

If you are not sure if a verb is transitive or intransitive in English, try putting an object after it.

Question: What did Robin start? Answer: The group project. Therefore ‘started’ is transitive.

Intransitive:

Intransitive

Question: What did Robin laugh? Answer: Nothing. Therefore ‘laugh’ is intransitive.

Some verbs can be either transitive or intransitive, depending on the context. e.g. I ran the race (transitive); I ran (intransitive). If you want to know if a verb is transitive or intransitive, look in a learner’s dictionary of English. Good online learner’s dictionaries that you can access free of charge are the Cambridge Advanced Learner's Dictionary, the Macmillan English Dictionary, Merriam Webster's Learner's Dictionary and the Oxford Advanced Learner's Dictionary

In active sentences, the subject of the sentence is the one doing the action.

In passive sentences, the object of the active sentence becomes the subject of the passive sentence.

The subject can be a person, an animal or an inanimate object. English therefore uses the passive voice in situations that may not be possible in other languages.
