What are they? Please listen again and circle the reflexive pronouns. Ready? Go!T: Have you got the answers? Together, please!T: OK! Lets do some exercise to practice the usage of reflexive pronouns.Such as:I cant finish it by (me)You should do it (you)But I guess they may have problems (they).Listen to 2a again and try to circle the reflexive pronouns and finish some exercises.Ss:Ss: myself; yourself; themselves.Do the exercise to master the usage of reflexive pronouns.S1: I cant finish it by myself (me).S2: You should do it yourself (you).S3: But I guess they may have problems themselves (they).該部分旨在引入本課重點(diǎn)語法項(xiàng)目反身代詞。Remark:在聽2a前可以先討論圖片以此降低聽的難度，建議學(xué)生在聽的過程中注意力放在獲取填空信息上;教師在完成2b后，可將2b中含有反向代詞的句子挖空進(jìn)行練習(xí)。Stage 3（9mins）：Phonetic learningStepTeacher activityStudent activityDesigning purpose 1( Class work )Show phonetic cards one by one.T: Now were going to learn some phonetic symbols. Look at the phonetic cards /kl/,/dl/ can you read them ? T: Ill play the recording of 3a. Please read after it.

Do remember: When such words like him, her are linked with other words, h is mute. Lets begin!T: Ok. You can check in pairs. A reads, while B listens and corrects.T: Please read with the recording.Read 3b after the recording and try to imitate, paying attention to the liaison, weak form and incomplete plosion. Ss:Ss:該活動旨在引導(dǎo)學(xué)生識別連讀、弱讀、不完全爆破等語音現(xiàn)象，并能在說英語時運(yùn)用這些語音規(guī)則。Remark：先復(fù)習(xí)單個音素，再讓學(xué)生直接讀單詞，分類歸納相似發(fā)音；像him,her這樣的詞在與其它詞連在一起時，h通常是不發(fā)音的。Stage 4（6mins）：PracticeStepTeacher activityStudent activityDesigning purpose (Class work)Design some exercise to review the usage of reflexive pronouns and auxiliary verbs or modal verbs.
