主编：黄冈中学英语集体备课组
Step 1 The introduction to the text
Do you like detective stories? Do you want to be a detective？A detective must be good at making inferences. From Section A, we learn we can make guesses by using modal verbs, such as must, could, might, can’t. Please look at this bag and guess its owner. From the style of the bag, we guess it is a woman’s bag. The bag might belong to an adult because its color is dark. In the bag, there are two books. One is an English textbook, so the owner could learn or teach English. The other is a teachers’ book. So the bag must belong to an English teacher.
