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.
