( 重庆卷 B 段) 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.

There are four parts in the book: Part is Messages: In this part somebody wants to send information in writing to somebody else. There is a test on timetables and a test on text messages. Part is People: In this part all the tests are about people. For example, there is an informal letter between friends. There is formal (正式的) 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 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 is Things: You will find some descriptive writing in this part. There are descriptions of clothes and of a computer.
