We use them when talking to a
person we don’t know very well,
or in professional situations, and
their form is a little different.
Too and enough

used with adjectives. •Too means more
than what is needed. •Enough means
sufficient.

of gerund verbs).

Will and going to
If you are making a
future prediction
based on evidence in
the present situation,
use 'going to'.
When we want to talk about future
facts or things we believe to be true
about the future, we use 'will'.
Adverbs of frequency
We use some adverbs to
describe how frequently
we do an activity.
Passive/ Active
In most English sentences with an
action verb, the subject performs the
action denoted by the verb.
One can change the normal word order of
many active sentences (those with a direct
object) so that the subject is no longer active,
but is, instead, being acted upon by the verb -
or passive.
Present Perfect
The present perfect is formed by combining the auxiliary verb "has" or "have" with the past
participle.
