Subjects and objects have the opposite functions in a sentence.

•   A subject is the person, place, or thing that performs the action (verb).
•  A noun or pronoun can be used as the object in a sentence. An object is the person, place, or thing that receives the action.
• In grammar, we use the word 'subject' to talk about the pronoun, noun, or noun phrase that does the action of the verb. In English, the subject is usually before the verb.
• In grammar, we use the word 'object' to talk about the thing or person that the verb is done to, or who receives the verb. It can be a noun, a noun phrase, a pronoun, or a longer complex object, which is modified (in a similar way to a complex subject).

•  I suggest that we all watch the movie ‘TIGER’. Here, 'I' is the SUBJECT and the movie 'TIGER' is the OBJECT.
• It has been suggested that we watch the movie 'TIGER' together. Here, 'WE' is the SUBJECT and the movie 'TIGER' is the OBJECT.
• These two statements are explaining the role of object and subject.

Thus, it is concluded that The two given statements can be differentiated by drawing students’ attention to the roles of the subject and object in both sentences.
