What can be a subject or an object of a sentence? Is that only noun can be a subject or an object? I don’t think so. How about word group and clause? Can they become a subject or an object of a sentence?
e.g. Shopping for clothing and other items (subject) satisfies personal needs. The subject here is a word group I guess
To design a mall (subject) is to create an artificial environment. The subject is also a word group? BTW, the object here is to create or to create an artificial environment?
Whether the program would succeed (subject) depended on door-to-door advertising. The subject is a clause.
It was surprising that Mary was nominated. Here the object is a clause.
Hope you can correct me. THanks.
