Introducción

In describing the changes, I mention what I have now and not before, or what I do, but it is not to, things, physical characteristics or attitudes that have changed me.I can describe the changes in sentences in present, past, present perfect or comparative.
Example:

-With the present tence:  I am now a more sociable person....Ahora soy una persona mas sociable.

-Whit the past tence: Im fat........estoy gorda

-With the present perfect: I have taken responsibility...... Yo me he hecho responsable.

-With the comparative........ The teacher is more strict than last semester.... La maestra es mas estricta que el semestre pasado.

The city is bigger than last year..... La ciudad esta mas grande que el año pasado.
