Unit 11b: Book
Start by going through the book. It will guide you through the unit material step by step.
1. Introduction
Like Unit 11a, Unit 11b uses the context of the Sayano-Shushenskaya hydroelectric power station accident to give you an opportunity to revise some grammar points as well as to learn something new. When studying the details of the tragedy, you will revise hyphenated adjectives and phrases used to speculate about the past. On top of that, the unit is also going to discuss some possible precautions that would have prevented the incident. To talk about these speculative precautions in the past and to express regret, the third conditional is usually used.
