    Reading is very important to help you learn English. To learn as much as you can from reading, you

need to read different kinds of English. This book provides not only different kinds of English but also a

good way to check your reading ability.

   There are four parts in the book:

   Part 1 is Messages: In this part somebody wants to wad information in writing to somebody else. There

is a test on timetables and a test on text messages.

   Part 2 is People: In this part all the tests are about people. For example, there is an informal letter
