教師寄語：It’s never too late to mend. 亡羊補牢，猶為未晚。
學習目標：
學習一般過去時的被動語態和特殊疑問句。

Telephone, calculator, car, personal computer, TV, electric light, light bulb, alarm, clock, microwave oven, electric slipper.
2. 自主學習：presentation
1) When was the car invented? It was invented in……
Choose the three inventions of these and ask students to guess when each one was invented.
For example, you might choose car, telephone, and personal computer.
Have several different students guess and write the dates on the board. Ask the class to repeat the questions and answers.
[T=Teacher, S=Student]
T: When was the car invented ? (Class repeat.)
T: Good. Now Jackie, what was your guess?
S1: 1900
T: OK. Jackie, repeat after me. The car was invented in 1900.
Repeat the process with several different inventions.
At last, make students find out the real dates.
2) 教學Who were the light bulbs invented by? And what are they used for ?
呈現Edison and light bulbs的畫面。
Tell the students Edison invented light bulbs.
Then ask the students to answer the questions below.
T: Who were light bulbs invented by? ( Class repeat )
T: Good. Now Class repeat after me. They were invented by Edison.
3. 合作探究：
1)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.
5. 梳理知識：本單元主要學習了一般過去時的被動語態，包括其結構與用法。利用幾項發明創造練習這一知識，最后用一篇小報告來完成寫作練習。
6.達標測試：
（一）根據時間和人物寫出發明物。
1) 1885____________ 2) 1876 ________________ 3) 1927____________
4) 1976 ________________5) Julie Thompson _________6) Chelsea Lanmon ______
（二）漢澤英
1)計算機是何時發明的？
2)誰發明了計算機？
3)計算機是用來做什么？
4)你認為什么是最有用的發明？
5)它能夠給人們更多時間工作和玩。
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是現在完成時，因此可排除A和C，區別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
