1. INTRODUCCTION
As a compilation of some of the most important topics that we have studied during
the quarter, the intention I want to obtain with this presentation is not only a self-assess
about the gained knowledge but also to share it with my classmates, and at the same time
could serve to the professor as a measurement of the individualized achieving of the initial
courses objectives, y also allow me to storage important material that can be very useful
during all my career.
From the all topics that we saw; I chose one; which are not exactly the most easily
understood and assimilated to me, if not the opposite; in which I found greater degree of
difficulty and I think is the most extensive and may include or relate to the other ones. It
with the intention of being rechecked important details, in order to can understand them
better and especially to spend a little more time in the practice of them.
I hope my proposal will help you as much as to me to continue expanding our
English knowledge and that this language every day becomes to be a better tool for our
intellectual and professional development .

2. VERBAL TENSES
To use correctly past, future and present tenses there are just a few rules to keep in
mind. For example If you know how to use the present progressive correctly to express
present actions, you will as well be able to use the past progressive correctly to express
past actions. See graphically is a good way to memorize things, topics, rules, formulas etc,
in my opinion this Graphic Comparison is a good tool that could help us to understand how
and when to use which tense verb in each case.
