The usage of "also": could someone please give an example to illustrate where is the location "after the verb to be when it is a full verb"?

Question

This video (https://youtu.be/38-K2rPu8fc?t=79) is talking about the usage of "also"

In addition 'also' can be used in the normal mid position of adverbs. What is that? It is between the subject and the predicate, or after the modal verb, or after the first auxiliary verb, or after the verb to be when it is a full verb.

There are 4 locations where the "also" could be put.

1. location_1: between the subject and the predicate
2. location_2: after the modal verb
3. location_3: after the first auxiliary verb
4. location_4: after the verb to be when it is a full verb

she gives these examples

She works very hard, but she also goes to the gym every week.

which applys location_1

I've been working in a garden this week and I've also been reading a lot.

which applys location_3

I am aware what first 3 locations mean, the question is location_4, what does that mean?

Answer 1

The verb "to be" (ie: am, is, are, was, were) can be an auxiliary verb (in "I am eating lunch") or the main verb (in "I am happy").

The word "also" can go after the verb in the latter case:

He is big. He is also happy. He's also a bear.
