Sinopsis

The perfect tenses ? both

present and past ? are

explained and used

prominently in most of these

readers. Many introduce the

passive voice, and most feature

the future tense. Nearly all of

them also include exercises to

develop understanding of the

first conditional, and some

include instruction in all three

conditional forms. More modal

verbs and more complex verbal

constructions ? using gerunds

and infinitives ? are presented.

There is a generally higher level

of vocabulary, sometimes quite

sophisticated.
