In active voice – subject+verb+object, subject. The rules for the active, passive voices are given below – Present Simple Tense To change the voice of the sentence, certain rules need to be followed and kept in mind. When the doer of the action or the subject is not present in a situation, then a grammatical subject can be included like ‘someone, somebody, him, her’.Įxample – Somebody cleaned the floor.

Hence, the verb in the sentence acts upon the subject. There is an addition of the preposition ‘by’. The main focus of the sentence has shifted from the police to the robbers in a passive voice. In this sentence, the places of the object and subject have been replaced. Let us consider the example given below – The robbers were chased by the police. Sometimes, it gets complicated to convert these sentences because it also requires the addition of a preposition. Here, the conjugated form of the verb ‘to be’ is used. The change of voice then takes place from passive to active, and it is mostly accompanied by ‘by’. Unless used correctly, this form of voice seems weak. In the passive voice, the sentence’s verb acts upon the subject of the sentence. The main focus is on the subject, that is, the police. The subject (police) is acting upon the verb. In this sentence, police are the subject, chased is the verb, and robbers are the predicate. Let us consider an example – The police chased the robbers. The change of voice will then take place from active to passive.

The tone of these sentences is perfect and precise. In an active voice, the subject in the sentence does the action.

It is the most suitable way to write down a sentence. In grammar, any particular sentence having the verb in an active voice shows the subject acting upon the verb present in the sentence. The action and the position of the subject also get changed. The verbs in the sentences get changed as the subject changes after their conversion from active to passive voice or vice-versa. The voice of a verb can be changed from active to passive or from passive to active. There are two types of voices, active and passive voices. This is not because it's 'hard' grammatically to come up with an easy method it's because passive voice, by definition, is lacking in the information needed to automate the transformation.The change of voice is a crucial topic of English grammar. Short answer: there is no 'easy' way to accomplish conversion from third person passive to third person active unless you know the actor performing the action for each passive sentence. (Note I maintained the past tense as in your original passive voice sentence.)

They implemented and tested two different versions of the generalized polynomial chaos finite element method in this paper.

If, as in the provided example, the subject is the authors, but you wish to speak in the third person, then you can replace the first person subject (as in your example above) with either 'the authors' or 'they': If you are trying to convert the sentences to 3rd person active, you have to be able to identify the subject of each sentence. Can you clarify why first person is not sufficient? Is it merely that you wish to avoid the use of first person pronouns in a scholarly paper? Your rearrangement is grammatically correct and semantically clear. Your rewording (to 1st person active) assumes that the performers were the authors throughout the paper, which is why it's easy to add 'We' and rearrange accordingly. This is why passive voice is frowned upon - because it does not present as much information. In order to convert from passive voice to active voice, you have to specify the subject that performed the action of the verb.
