一、落實(shí)預(yù)習(xí)：見《助學(xué)》第133頁(yè)翻譯探究
教學(xué) 操練1a, 1c, 2c
學(xué)生看書本上1a的圖畫，根據(jù)圖畫，把1a, 1c, 2c中的語(yǔ)言點(diǎn)綜合起來(lái)，叫學(xué)生相互間回答問(wèn)題。并用剛剛學(xué)到的目標(biāo)句型來(lái)操練。最后，抽查幾對(duì)學(xué)生，讓他們?cè)谌嗝媲�，按要求進(jìn)行對(duì)話。
2)教學(xué)1b, 2a, 2b
首先，幫助學(xué)生明確本題的要求。接著，聽力練習(xí)，學(xué)生根據(jù)錄音內(nèi)容完成1b, 2a and 2b.
最后，重放一遍錄音內(nèi)容，學(xué)生跟讀。
4、拓展創(chuàng)新：
Consolidation and Extension.
完成一個(gè)任務(wù)
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.

1)計(jì)算機(jī)是何時(shí)發(fā)明的？
2)誰(shuí)發(fā)明了計(jì)算機(jī)？
3)計(jì)算機(jī)是用來(lái)做什么？
4)你認(rèn)為什么是最有用的發(fā)明？
5)它能夠給人們更多時(shí)間工作和玩。
三 精講點(diǎn)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(cè)這句話的意思應(yīng)該是“它每天都被打掃”，考查被動(dòng)語(yǔ)態(tài)的結(jié)構(gòu)be + 動(dòng)詞的過(guò)去分詞。因此答案應(yīng)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(cè)這句話的意思“我很了解北京，我去過(guò)那三次”。表示去過(guò)應(yīng)該采用的時(shí)態(tài)是現(xiàn)在完成時(shí)，因此可排除A和C，區(qū)別have been和have gone,have been 去過(guò)；have gone 去了（還沒回來(lái)）。因此應(yīng)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(jié)梳理知識(shí)：本單元主要學(xué)習(xí)了一般過(guò)去時(shí)的被動(dòng)語(yǔ)態(tài)，包括其結(jié)構(gòu)與用法。利用幾項(xiàng)發(fā)明創(chuàng)造練習(xí)這一知識(shí)，最后用一篇小報(bào)告來(lái)完成寫作練習(xí)。

1. Potato chips were invented by mistakes. mistake 作名詞 “錯(cuò)誤” make a mistake 出錯(cuò)e.g. You have made a mistake here. mistake…for… 錯(cuò)把……當(dāng)作…… They mistook him for his brother. by mistake 錯(cuò)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(fù)合賓語(yǔ)。常見結(jié)構(gòu)為：主語(yǔ)+make+賓語(yǔ)+名詞/形容詞(做賓補(bǔ)) water (產(chǎn)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(dǎo)讓步狀語(yǔ)從句, 我們不能根據(jù)漢語(yǔ)習(xí)慣, 在后面使用連詞but, 不過(guò)它可以與yet, still連用;若主從句的主語(yǔ)相同, 且從句謂語(yǔ)含有動(dòng)詞be, 可將從句主語(yǔ)和動(dòng)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(dǎo)一個(gè)時(shí)間狀語(yǔ)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(gè)短語(yǔ)介詞,意為 “根據(jù)……;依照……”后接代詞,名詞或由疑問(wèn)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(duì)象是 本來(lái)存在的。 find意為“找到”，強(qiáng)調(diào)結(jié)果。 invent意為“發(fā)明”，發(fā)明的對(duì)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(fù)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．
