This textbook, as all of the others, is an excellent book however, it is a college level book amd might be a bit a t times, too hard for High-schools.   It will be up to the teacher to adapt the material to the level taught.  Of all them, this would be my choice given online support. Drawing and phots are frequently used to support the presentation. All activities and readings  withing each unit recycle the vocab from previous unit. Students would be able to improve  and develop language skills and reinforce, at the same time, the cultural points respecting the 5 C of learning a language. It helps students foster self-confidence, self directed and student-center activities that will promote independent thinkers amd learners.
