【合作探究】
一、落實預習:見《助學》第133頁翻譯探究
教學 操練1a, 1c, 2c
學生看書本上1a的圖畫,根據圖畫,把1a, 1c, 2c中的語言點綜合起來,叫學生相互間回答問題。并用剛剛學到的目標句型來操練。最后,抽查幾對學生,讓他們在全班面前,按要求進行對話。
2)教學1b, 2a, 2b
首先,幫助學生明確本題的要求。接著,聽力練習,學生根據錄音內容完成1b, 2a and 2b.
最后,重放一遍錄音內容,學生跟讀。
4、拓展創(chuàng)新:
Consolidation and Extension.
完成一個任務
Ask some students to read about an invention using an encyclopedia or other book from the library, or by looking up information on the Internet. Have the students write up a short report and draw a simple picture of the invention or bring in a photo of it. Ask each students to show the picture and read his or her report to the class.
二 小組探究(二)漢澤英
1)計算機是何時發(fā)明的?
2)誰發(fā)明了計算機?
3)計算機是用來做什么?
4)你認為什么是最有用的發(fā)明?
5)它能夠給人們更多時間工作和玩。
三 精講點撥典型例題解析:
1.--What a nice classroom! --It ____ every day.
A. is cleaning B. has cleaned C. must clean D. is cleaned
解析:推測這句話的意思應該是“它每天都被打掃”,考查被動語態(tài)的結構be + 動詞的過去分詞。因此答案應該選D。
2.I know Beijing well. I ____ there three times.
A .will go B. have been C. went D. have gone
解析:推測這句話的意思“我很了解北京,我去過那三次”。表示去過應該采用的時態(tài)是現(xiàn)在完成時,因此可排除A和C,區(qū)別have been和have gone,have been 去過;have gone 去了(還沒回來)。因此應該選擇B。
中考連接:
1.--Look at the sign on the right. --Oh, smoking ____ here.
A .doesn’t allow B. isn’t allowed C. didn’t allow D. wasn’t allowed
2. --Will you come to the dinner party? --I won’t come unless Jim ______.
A. can’t be invited B. was invited C. will be invited D.is invited
四 歸納總結梳理知識:本單元主要學習了一般過去時的被動語態(tài),包括其結構與用法。利用幾項發(fā)明創(chuàng)造練習這一知識,最后用一篇小報告來完成寫作練習。

1)教學 操練1a, 1c, 2c學生看書本上1a ,1b 完成1a,1b 2)教學2a, 2b ,聽一聽 填一填 完成2a and 2b. 3)2a,2b 回答問題1. What is this article about? 2. Was it invented on purpose or by accident? 3. When was it invented? 4. Who was invented by? 二.精講點撥:
1. Potato chips were invented by mistakes. mistake 作名詞 “錯誤” make a mistake 出錯e.g. You have made a mistake here. mistake…for… 錯把……當作…… They mistook him for his brother. by mistake 錯誤地 e.g. They sent the letter to me by mistake. 2. Geroge wanted to make the customer happy. make表示“使……怎么樣”,其后常帶復合賓語。常見結構為:主語+make+賓語+名詞/形容詞(做賓補) water (產生) a p smell . 典型例題解析:1. Did you know that tea…was invented by accident? by accident “偶然地,碰巧”。同義詞組 是by chance,同義詞是accidentally, 反義 詞組是on purpose. e.g. he found a new way to solve the problem by accident. 2. Although tea wasn’t brought to the western world until 1610, …(1) although 作連詞, 意為 “雖然,盡管”,引導讓步狀語從句, 我們不能根據漢語習慣, 在后面使用連詞but, 不過它可以與yet, still連用;若主從句的主語相同, 且從句謂語含有動詞be, 可將從句主語和動詞be省略。e.g. Although he is very busy, he always talks with us. (2) not…until 意為 “直到……才”until 引導一個時間狀語從句。 I did not go to bed until I finished my homework. 3. According to an ancient Chinese legend, the emperor Shen Nong discovered tea…(1) according to 是個短語介詞,意為 “根據……;依照……”后接代詞,名詞或由疑問詞以及whether引出的名詞性從句。e.g. According to the radio, it will rain tomorrow. (2)discover意為“發(fā)現(xiàn)”,指發(fā)現(xiàn)的對象是 本來存在的。 find意為“找到”,強調結果。 invent意為“發(fā)明”,發(fā)明的對象是以前沒 有的東西。3. Some leaves from a nearby bush fell into the water and remained there for some time. (1) nearby adj. “附近的“,e.g. He works in a nearby factory. (2)leaf 的復數(shù)形式為leaves (3)remain 表示 “繼續(xù)留在某處” e.g. How long will you remain here? (4) fall into “落入, 陷入”e.g. He was drunk and fell into the water.

三.當堂檢測:見助學P135——136 四.鞏固測評 Complete the sentences :
