UNIT 1: VOCABULARY

This is the list of words or concepts which you have to know and to learn for the next exam.
In order to have the notebook well organized, you have to write the list always on the last page of the unit, so you can do a sketch of the list on other sheet of paper and copy it on the last page of the unit when we finish it.
The meaning of each word should be written in English after each word. Please, pay attention to this advice.
All the words or concepts can be found in your book of Basic Concepts, but if you do not find some, ask the teacher. Good luck!!
