個性化補充step i presentation1.tell students one of my friends will leave home for some time.so he asked me to look after his dog.i don’t know how to look after a dog.my friend gave me some instructions.can you help me take some notes? please take out yournotebooks and write down the following instructions.(1)give him enough food every day.(2)give him clean water.(3)brush his fur every morning.(4)take him out for a walk at least once a day.(5)play with him for some time every day.(6)keep him warm at night.(7)don’t pull his tail.(8)don’t kick him.2.let students read these sentences and find out the differences with the ones we use. 3 .explain that we start a sentence with the base form of a verb when we want to tell people to do something.we add ‘don’t’ in front of the verb when we want to tell people not to do something.imperative sentences do not normally include a subject, because the subject ‘you’ is implied. however, a noun or pronoun can sometimes be used to identify the person receiving an order or instruction, e.g., the speaker wants to attract mary’s attention and so he/she says, ‘mary, don’t push.’ / ‘don’t push, mary.’. to be polite，we always use ‘please’ with the instructions.please don’t push, mary.’.step ii taskwrite some instructions on the board. then ask them about the situations in which we use them. ask classes to create a list of different instructions and then write the different situations as titles above it, e.g.,classroom sit down.open the door.be quiet.stop talking.work with a partner.please close the window.on the busdon’t push.take good care of your wallet.…step iii task1.go through the explanations and grammar table on page 98 to clarify the rules for using imperatives when giving positive and negative instructions.2.ask students to study the pictures in part a1. check their understanding of the situations presented in the pictures. 3.ask less able students to work in pairs to select the correct word to fill in each gap, then match the pictures with the instructions. when they have finished, ask them to read each instruction to their partner.
