JACK, LISTER
The simple past tense is used
prominently in these readers.
Thus, students gain exposure
to the conjugation of some
irregular verbs.
Most also include verbs
in the simple future.
A few modal verbs are
presented, with explanations
of their use. These stories also
use a greater variety of verbs
of speech. There is deeper
exploration of comparative
and superlative adjectives.
Some of these readers also
include explanations of more
complex grammatical
structures, such as first
conditional and infinitive
constructions, and most have
examples of verb use in
interrogative and negative
sentences.
