This second volume covers five main areas of English grammar: tenses, modal verbs, phrasal verbs, the reported speech and the passive voice.
If a student wants to maintain both ways of communication better, that is, speaking and writing, s(he) needs to gain mastery over English tenses.
Similarly, a student can use modals to do things like talking about ability, asking permission, making requests, offers and so on.
In addition, learning to use phrasal verbs correctly will help a student sound natural in casual conversation.
Last but not least, the reported speech and the passive voice are dealt with at length in the last section of this book.
