情態助動詞 A2

Now, we've already talked about
how verbs can show actions

委婉語氣表達希望、渴望

and link concepts, and today
I'd like to talk about a third

function of the verb, which
is helping other verbs.

Now we call this the helping
verb, you may have heard it

These are just two words
for the same thing,

auxiliary is just a more
Latin way to say helping,

Now I've brought along an
image of my friend Brian

What helping verbs are is
really just inflected forms

And as we get deeper into
the verb, I'll explain

what each one means in each
one of its different versions,

but for now, suffice it to
say, I'm just gonna throw

out some examples, just so
you can see what it means

So the specific way in
which helping verbs help

is that they establish certain
facts about a sentence,

And we'll get more and
more into that as we get

more into tenses and aspect,
but I just wanna give you

So, here we have Brian is eating a pizza.

Brian and I love pizza, we
used to eat a lot of pizza.

And, finally, Brian had
been eating a pizza.

So the presence of all these helping verbs

has different effects depending
on which ones you use.

And, as I said, we'll
get into those later,

but, just for a brief
overview, for example,

let's see, Brian is eating
a pizza, that suggests

Brian has eaten a pizza,
that means he had done it,

Brian was eating a pizza, which
means he was in the middle

of eating a pizza when something happened.

So he was doing it, and then
he stopped at some point

And this is just the
most basic introduction

So, verbs can show actions,
verbs can link concepts,
