The Impact Listening 2 Teacher's Manual provides step-by-step procedures for presenting each unit. Answers to the activities along with the listening audio scripts are provided for each unit. In addition, practical teaching tips, stimulating extension activities, and informative language and culture notes can be found throughout the Teacher's Manual. The Test Master CD-ROM Pack includes a CD-ROM which contains test document files, and the Test Audio CD, which contains 75 audio tracks. In each Test Master CD-ROM Pack, there is a set of Unit Tests, one for each of the fifteen main units in the course. The Unit Tests have two parts, Part A is a vocabulary review of the core items of the unit, most of which are covered in the Warm Up section. Part B is a five-item comprehension test that is based on an extract similar to one of the Listening Task conversations or to the Real World Listening extract. The Test Master CD-ROM pack also contains two Semester Tests, one for Units 1-8 (Test 1), and one for Units 9-15 (Test 2). There are two forms of each test (Tests 1A and 1B, and Tests 2A and 2B) so you can alternate forms in different classes or use a different form for a make-up test. - from Amzon
