　Lesson 99教學設計示例

一、教學目標

1．知識目標

區別一般過去時態和過去進行時態。

2．能力目標

能夠區分在什么情況下用過去時態，什么情況下用過去進行時態。

3．情感目標

教育學生要注意交通安全。

二、教具

錄音機；在教室一角布置一個“交通事故現場”。

三、課堂教學設計

1．復習 教師檢查課文復述。

2．要求學生四、五人就近一組。其中一位同學扮演警察，手持一個“記錄本”；其他同學以“見證人”的身份向“警察”紛紛敘述事故發生的經過。四、五分鐘以后，請兩個大組到布置好的地點去表演。

教師也可考慮將學生分為若干個小組，分別扮演以下角色和準備以下內容：

1）李磊敘述事情經過；2）看門人敘述事情經過；3）趙老師敘述事情經過；4）騎摩托車人敘述事情經過。

以下提示供教師備課時參考：（可用投影形式展示）

角色1 (Li Lei) left school and saw a bag fall off a truck; shouted to the driver, but the driver did not hear; a man on a motorbike hit the bag and fell off; came up to help; asked the girl students to stop the traffic; helped to carry the man to the gate keeper's room, went to find Miss Zhao

角色2 (the gate keeper) heard the children shouting outside the school gate; went out to see what happened; saw two boy students carry a man; asked the people not to crowd around the man; asked Li Lei to find a teacher; moved the bag of rice away with Lin Tao

角色3 (the man on the motorbike) rode too fast that day; saw the bag, but too late; had an accident and fell off; hurt, could not move; two boys came to help; a teacher came with a medicine box; took me to a hospital

角色4 (Miss Zhao) reading a book at the library; Li Lei ran in and looked worried; told me about the accident; asked Li Lei to telephone the police; went to find a medicine box; quickly ran to the gate keeper's room

3．全體同學填寫“事故報告”，教師應要求學生完全用書面形式答出。當堂核對答案。

4．教師扼要講解一般過去時態與過去進行時態的區別（見難點講解）。

5．打開練習冊，給學生一分鐘時間看聽力練習提示。聽錄音三遍，當堂核對答案。

6．指導學生做練習冊其他習題。

7．布置作業

1）繼續準備第18課課文復述；2）書面完成練習冊其他習題。

四、難點講解

過去進行時態和一般過去時態的區別：

過去進行時態表示過去某一時刻正在進行的動作，而一般過去時態表示一個完成的動作。請比較以下兩組句子：

I was writing a letter last night. 昨晚我在寫一封信。（信可能沒有寫完）。

I wrote a letter last night. 昨晚我寫了一封信。（信已經寫完）。

I was doing my homework when he phoned me. 他給我打電話時，我在寫作業。（表示當時沒做其他事情）。

I did my homework and went to bed. 我寫了作業然后睡覺了。（表示說話人所做的兩件過去的事情）。
