4、能夠正確理解和運用句型：they aren’t here/ there now. they were here/ there a moment ago.并練習四會句型的書寫。
5、正確理解和朗讀課文第二部分對話。
教學重點：
1、學習“be”動詞are的過去式were，鞏固過去時的表達方式。
2、能正確理解并運用句型：they aren’t here/ there now. they were here/ there a moment ago.
學會復數的表達方式。
3、掌握本課時的四會單詞和句型。
教學難點：
1、正確運用be動詞過去時的單、復數形式。
2、能夠運用所學的句型進行尋找物品的情景會話。
準備教具：
錄音機 磁帶 單詞圖文卡 實物（眼鏡和耳機）
教學掛圖（對話情景圖片） 詞條（事先打印好單詞或詞組）
教學過程：
step 1 revision
1、review the words：出示課本b部分掛圖
t: today su hai and su yang’s cousin, gao yun is visiting them. let’s have a look.
what’s this?
s: it’s a roll of film/a mobile phone/a cd walkman/a diary/a handkerchief.
相機出示單詞a video recorder，組織學生朗讀。
齊讀六個單詞。
2、ask and answer: 出示課本c部分圖片（1—6題）
a: where’s your…?
b: it’s on/ next to/ beside/ in/ in front of…
a: it isn’t there now.
b: it was there a moment ago.
先看圖說話，再用身邊的文具用品進行會話練習。
step 2 presentation
1、教師指著實物問學生：
t: what’s this?
s: it’s a computer/ a mobile phone/ a pair of glasses…
t: yes, it’s a pair of glasses.
出示單詞a pair of glasses，組織學生朗讀。
區別比較glasses和a pair of glasses：
glasses強調使用復數，a pair of glasses強調使用單數。
書面練習：where   the glasses?
the glasses   on the desk.
where   the pair of glasses?
the pair of glasses   on the desk.
  t: where are my glasses?
s: they are on/ next to/ in front of/ between…
教師相機板書：where are my glasses?
they are on/ next to/ in front of/ between…
2、學生讀詞組a pair of glasses （隨后把放在一個不顯眼的地方）
  說出已學詞組：a pair of   (gloves, shoes, socks, trousers, jeans…)
  教師隨機取出一對耳機，教說單詞earphones, a pair of earphones
  t: where are my earphones?
s: they are in / under…
(教師繼續在板書they are on/ next to/ in front of/ between…之后添加介詞in/ under…)
組織學生齊讀板書（順便把眼鏡、耳機放在一個不顯眼的地方）
3、t:（學生讀完板書，教師故作尋物狀）
oh! where are my glasses?
  ss: they’re ……
  t: oh, they aren’t here/ there now.
  組織學生學說這個句子。
  t: but they were here/ there a moment ago.
  組織學生理解朗讀were，they were here/ there
  師生操練：t: where are my glasses?
s: they are ……
t: they aren’t here/ there now.
s: they were here/ there a moment ago.
請學生說說were的用法，教師板書are過去式 were。
4、操練句型：結合課本c部分（7—12題）練習
