Active and passive

ACTIVE & PASSIVE VOICE Active And Passive Voice: An idea can be expressed in two different ways. We can do it by using a verb to indicate whether the subject performs an action (active voice) or receives the action (passive voice). Active voice: The verb is in the active voice when the subject does the action. Ex: A cat ate the fish. (Subject: cat /Verb: ate /Object: fish) Here, the doer of the action is a cat and the verb "ate" is in the active voice. The object comes after the verb. Passive voice: When action is done to the subject, the verb is in the passive voice. The previous object (fish) is now used as the subject. Ex: The fish was eaten by a cat. (Verb: eaten /Subject: fish) Here, action is done to the subject and the verb "was eaten" is in the passive voice. The subject comes before the verb. Note -In changing a sentence, as above, from active voice to one in the passive voice, we make the object of the active voice sentence the subject of the passive voice sentence. The verb used in a passive voice sentence is formed by adding the past participle to "to be" (am, is, are, was, were, has been, have been, will be, etc.) Passive verbs have the same tenses (simple present tense, present continuous tense, present perfect tense, etc.) as active verbs. Only verbs which take on an object can be changed to the passive. (Example: He runs away. This sentence has no object, so it's not possible to turn it into a passive sentence.) When we choose passive sentences, we use the preposition 'by' to show who or what does or has done the action (as shown above: The fish was eaten by a cat.) We use 'by' only when we have to. When To Use The Passive Voice: We use the active voice whenever we can. We use only the passive voice: When we don't know who performs the action; Ex: The bank was broken into last night. When we know or it is important to know who performs an action. Ex: This painting was done by my grandmother. When the action itself is more important than the doer. Ex: Siblings were tragically killed in a road accident. When we are interested only in what happens rather than who or what did it. Ex: The giant snake was killed in that village. When we choose not to name the one who performs the action. Ex: The work was poorly done. When it is not important to know who does, or did the action; Ex: All these wares were imported from Hong Kong. when we don't want to take responsibility for something; Ex: The matter is currently dealt with by someone. When we wish to emphasize the person or thing acted on rather than the one who does it. Ex: John was presented with a bravery award yesterday. Facts About Passive Voice: Note: As evidenced above, in converting a sentence in active voice to a sentence in the passive voice, the object of the active voice sentence becomes the subject of the passive voice sentence. Ex: He drew the picture. /The picture was drawn by him. Sentences in the passive voice do not make sense if the "doers" are not mentioned. Ex: "The match was won." ('doers' left out) as opposed to "The match was won by Liverpool" A transitive verb is a verb that has an object that comes after it and so can be changed into the passive voice. Ex: "Lee throws a ball." can be changed to "A ball is thrown by Lee". An intransitive verb is a verb that does not have an object following it and so cannot be changed into the passive voice. Ex: Lee walks away. (INCORRECT: Lee was walked away.) The passive voice is often used to evade responsibility by people or organizations. Ex: The report was lost by somebody. (Who is that 'somebody'?) Ex: All workers are encouraged to work overtime. (Encouraged by whom?) Notices often use the passive voice. Ex: Customers are advised to leave all their belongings here. An active sentence when changed to a passive sentence conveys the same meaning. The only difference is that the object in an active sentence is repositioned to become the subject in a passive sentence, and the subject in the active sentence becomes the object in the passive sentence. We need to be sure of what we are saying. If we are not sure of our facts, we can exercise caution by saying: It is said that he is the culprit. /He is said to be the culprit. It is possible to use 'get' instead of 'to be', especially so in our everyday conversation. Ex: I got cheated by the salesman. /They think he will get beaten in the race. Verbs With Two Objects: A verb can have two objects – a person and a thing. Such a verb can have two possible passive voices. Ex: Active: The salesman shows Nick a new computer. (OR) The salesman shows a new computer to Nick. Passive: Nick is shown a new computer. Passive: A new computer is shown to Nick. Ex: Active: We lent Bob some money. (OR) We lent some money to Bob. Passive: Bob was lent some money. Passive: Some money was lent to Bob. Passive Voice + Basic Modal Forms: Basic modal forms can be used in the passive voice by combining: modal + to be/to have been + past participle: Ex: Active Passive will I will write it will be written may I may write it may be written may have I may have written it may have been written We form the passive voice with the verb ‘to be’ and the past particle. The passive forms are: Simple Present Tense: Ex: Active: She writes the letter. Passive: The letter is written by her. Present Continuous Tense: Ex: Active: She is writing the letter. Passive: The letter is being written by her. Present Perfect Tense: Ex: Active: She has written the letter. Passive: The letter has been written by her. Simple Past Tense: Ex: Active: She wrote the letter. Passive: The letter was written by her. Past Continuous Tense: Ex: Active: She was writing the letter. Passive: The letter was being written by her. Past Perfect Tense: Ex: Active: She had written the letter. Passive: The letter had been written by her. Simple Future Tense: Ex: Active: She will write the letter. Passive: The letter will be written by her. Future Perfect Tense: Ex: Active: She will have written the letter. Passive: The letter will have been written by her. Infinitive: Ex: Active: She has to write the letter. Passive: The letter has to be written by her. Modals: Ex: Active: She will/may write the letter. Passive: The letter will/may be written by her. Note: The present perfect continuous, the past perfect continuous, the future continuous, and the future perfect continuous tenses are not normally used in the passive voice.
