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 send information in writing to somebody else. There is
a test on timetable 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 between
friends. There is formal English in biography (传记). There is a job application as a model to help with your
writing, as well as testing your reading.
Part 3 is Places: In this part, too, many different kinds of English are shown, some informal and some
formal. There is the informal English of a holiday postcard. There is also the formal English in a letter of
complaint.
Part 4 is Things: You will find some descriptive writing in this part. There are descriptions of clothes and
of a computer.
You can do these tests in any order you like, or you can do all the tests with a formal or informal text. I
enjoyed writing this book and I hope you enjoy using it.
