In the first unit I learned about the huge influence of the computers and the technology in our lives.
It's very important to read the texts carefully, because many types of word can be used in different ways. For example, "store" it can be used as a verb or a noun, depending of the context.
I also learned to recognize adverbs on a sentence. Adverbs complements the verb, in the same way the nouns are complemented by the adjetives.
Something I didn't know were the collocations, phrases conformed by a noun and a verb. For example "surf the web" and "make calls".
Classifying is used to put things on groups, and it's very useful when we are designing a concept map, there are many expressions we can use such as "includes", "consists of" and "there are X types of Y".
Finally, we discovered more details about the PC system's components and I learned how to define things or people using the relative clauses, that can be left out in some cases.
