✖
It is important to remember that NonContinuous Verbs cannot be used in any
continuous tenses. Also, certain noncontinuous meanings for Mixed Verbs
cannot be used in continuous tenses.
Instead of using Present Continuous with
these verbs, you must use Simple
Present.
She loves this chocolate ice cream.
Non-Continuous
Verbs are usually things you
cannot see somebody doing. These
verbs are rarely used in continuous
tenses.

Abstract Verbs
to be, to want, to cost, to seem, to need, to care, to contain, to owe, to exist...
Possession Verbs
to possess, to own, to belong...
Emotion Verbs
to like, to love, to hate, to dislike, to fear, to envy, to mind…
Mixed Verbs have
more than one meaning. In a
way, each meaning is a unique verb.
Some meanings behave like "NonContinuous Verbs," while other
meanings behave like "Normal
Verbs."

Mixed Verbs
to appear, to feel, to have, to hear, to look, to see, to weigh...

I went to Mexico last year.
I have been to Mexico in the last year.
I have been to Mexico at
least once at some point
between 365 days ago and
now.
I have been to Mexico in the last year.

"Last year" and "in the last year" are very different in meaning. "Last year"
means the year before now, and it is considered a specific time which
requires Simple Past. "In the last year" means from 365 days ago until now.
It is not considered a specific time, so it requires Present Perfect.

Future tense expresses
action, activity and state of being in the future
Simple Future

has two

different forms in English: "will" and "be going
to." Both "will" and "be going to" refer to a
specific time in the future.

insurance.

Past

Present

Future

"Will" to express a promise

✖
No Future in Time Clauses
Like all future forms, the Simple
Future cannot be used in clauses
beginning with time expressions
such as: when, while, before, after, by
the time, as soon as, if, unless, etc.
Instead of Simple Future, Simple
Present is used.

Correct sentences:
When you arrive tonight, we will go out for dinner.
If you come on time, we will go out for dinner.
If you are tired, we won’t go out.
We will go out for dinner, unless you are too tired.
