You can use "goals" as a subject complement when you want to describe the nature or identity of the subject. Here's how it works:

* Subject: The person or thing being described.

* Linking Verb: A verb that connects the subject to the subject complement. Common linking verbs include "be," "seem," "appear," "become," "feel," and "look."

* Subject Complement: The word or phrase that renames or describes the subject.

Here are some examples:

1. Simple Subject Complement:

* Our main goals *are* to improve communication and build trust.

* His biggest goal *is* to travel the world.

* Her dreams *have become* her goals.

2. Subject Complement with Adjectives:

* The team's goals *are* ambitious and challenging.

* Their goals *seem* unrealistic.

* The project's goals *were* clear and achievable.

3. Subject Complement with Prepositional Phrases:

* The company's goals *are* in line with its mission statement.

* His goals *were* for a better future.

* Their goals *are* beyond our wildest dreams.

In these examples, the subject complement ("goals" or a phrase containing "goals") renames or describes the subject (e.g., "our main goals," "his biggest goal," "the team's goals").

Remember, the subject complement always follows a linking verb and provides information about the subject.
