Recognizing the Subject and the Object in a Sentence
Recognizing the Subject and the Object in a Sentence:
Sentences, as we have seen, are usually constructed with a subject, a verb and object.These sentences also have what is known as “voices”. Namely an active voice or passive voice.
The subject is usually the thing or person who is carrying out an action. The object is the thing or person that is involved in an action, but does not carry it out.
