Lesson 27

　　Note： This lesson revises the Present Perfect Tense.

　　Step 1 Revision

　　1 Revise the past and past participle form of the verbs like put， draw， cook， drink， start， do， give， see， etc.

　　2 Revise the Present Perfect by getting Ss to perform actions （e.g. close the window）。 Say Please close the window， （Li Lei ）。

　　Before the student performs the action， ask Has he /she closed the window yet？ Help the Ss to answer No， he /she hasn't. When the action has been completed， ask What has he /she just done？ Help the Ss to answer He's / She's just closed the window. Repeat with other actions， e.g. draw a flower on the Bb， put the book on my desk， clean the Bb， etc. Revise the meaning of yet and just.

　　Step 2 Presentation

　　SB page 27， Part 1. Speech Cassette Lesson 27. Books open. Play the tape for the Ss to listen and repeat.

　　Then get them to practise the dialogues in pairs. Make sure they use it and them correctly. Notice the position of already and the use of yet in a question or a negative sentence.

　　See if the Ss can make up some dialogues of their own.

　　Step 3 Practice

　　SB page 27， Part 2. Do the first one orally with the class as an example， then let them work in pairs answering the questions. Tell the Ss to pay attention to the whole sentence. Look at the meaning （e.g. we don't use drunk it to talk about a library book） and grammar （e.g. if we are talking about a plural word， such as eggs， we won't say eaten it ）。 Check the answers with the whole class.

　　The suggested answers are： returned it， given them to Polly， drunk it， eaten it， cooked them
