第一課時

module 1

step 1

1. 用 powerpoint 制作，插入一張電燈泡的圖片，依據講課內容，旁邊依次閃現 light bulb, invent, thomas edison, 1879.

2. t: look at the picture on the screen.

      what's that in english?

   ss: ...

   t: it's a light bulb. (students read “light bulb” after the teacher repeatedly.)

   t: who invented the light bulb?

thomas edison invented the light bulb in 1879. (屏幕上，在圖片的下面出現這句話。the teacher explains “invent” to help students learn the new word. “invent” means “to make, design, or think of a new type of thing”. students read “invent” after the teacher again and again.)

step 2

1. 邀請5名學生做個排序游戲：教師將事先準備好的大卡片隨意地發給4名學生，每張大卡片分別印有 the light bulb, thomas edison, in 1879, invented。讓他們自己排序，手持卡片、面朝大家排隊。

2. t: is it right, class?

  ss: yes/no.

3. 5 號學生做助手幫忙，找到正確的順序，并大聲朗讀，其他學生集體跟讀。

step 3

1. 教師特意地顛倒 “the light bulb”和 “thomas edison”的順序。

2. t: can we say like this?

  ss: no.

   t: we can say in another way in english.

3. 教師手拿印有 was 和 were 的兩張大卡片站在 invented 的前面，要求5號學生手持 by 插入 invented 的后面。教師分別用 was 和 were，要求其他學生朗讀，判斷用 was 還是 were. claps for them! 5 名學生回到座位上。

4. 板書說明

被動語態的構成：助動詞 be + 及物動詞的過去分詞

was/were + 如：invented, called, allowed, done 等

t: 英語動詞有兩種語態，即主動語態和被動語態。主動語態表示主語是動作的執行者，被動語態表示主語是動作的承受者。被動語態的助動詞 be 有人稱、數和時態的變化，其變化規則與 be 作為連系動詞時完全一樣。本單元主要學習一般過去時的被動語態。

5. 要求學生看屏幕，重復用被動語態的表達方式。教師點鼠標，在最下方出現

the light bulb was invented by thomas edison in 1879.

t: 當我們不知道誰是動作的執行者，或者沒有必要指出誰是動作的執行者，或者只需強調動作的承受者時，要用被動語態，刪除 by 引出動作的執行者。如屏幕顯示：

the light bulb was invented in 1879.

module 2

step 1

1. 切換兩張電話和多臺計算機的圖片，旁邊分別出現提示詞 bell, 1876和1976, personal computers.

2. t: talk with your partner about the invention with the words given.

完成任務所需要的語言結構：

① what is that/are they? it's/they're ...

② ... was/were invented by... in...

3. ask a few students to say.

4. 圖片下面呈現正確的說法：

the telephone was invented by bell in 1876.

the personal computers were invented in 1976.

學生重復朗讀，注意句中不同顏色的標注。

step 2

1. t: list your favorite books, songs, movies, tv shows and so on.
