2019-2020年九年級英語Unit9 When was it invented教案 學習目標： 1．學會使用含有被動語態(tài)的不同句型結構“When/ Where was it invented?” 和“What are they used for?--- They are used for doing sth..”來談論各種發(fā)明物的歷史。 　　2．學習理解被動語態(tài)的含義。能夠就不同的發(fā)明物與他人交流看法，發(fā)表自己的見解，并陳述理由。 　　3．了解到更多在世界上有重大意義的發(fā)明，并向那些偉大的發(fā)明家學習。 一、詞匯 1．基礎詞匯 invent　adjustable　 　 heel　 　 battery　 operate　 　 slipper　 　 scoop　　　 electric bulb　 　 microwave　　　 oven　 island　 sweet　　　 salty　 　 crispy　 　 sour　 potato　 chip mistake　 thin　 　 chef　 　 sprinkle　 beverage　 thousand　 according　 ancient　 legend　 　　　 emperor　 　 boil　 　 fire 　 leaf 　 nearby　 　 remain　 notice　 produce　 　　 pleasant　 smell　 　 taste　 　 metal　 　　 pie　 　　　 bakery　 throw　 　 special　 　　 abacus　 　 century　 telescope　 camera　 　 term 2．重點短語 　experience　 airplane　 India　 develop 二、日常用語 1. --- When was the car invented？ 　　　 ---It was invented in 1985. 　　2. ---When were electric slippers invented？ 　　 　---They were invented last year. 　　3. ---Who were they invented by？ 　　 　---They were invented by Julie Thompson. 　　4. ---What are they used for？ 　　 　---They’re used for seeing in the dark. 三、知識講解 Section A: 1.被動語態(tài) 謂語動詞的語態(tài)表示句子的主語和謂語動作之間的關系： 1）當句子的主語是謂語動作的執(zhí)行者時，主、謂之間的關系稱為主動語態(tài)； 　　2）當句子的主語是謂語動作的承受者時，主、謂之間的關系稱為被動語態(tài)。 　　　 例如： 　　 　I teach English.（主動語態(tài)）我教英語。 　　 　Our English is taught by him.（被動語態(tài)）我們的英語是由他教的。 　　 　He speaks English.（主動語態(tài)）他說英文。 　　 　English is spoken in many countries all over the world.（被動語態(tài)） 世界許多國家都講英語。 　　在被動語態(tài)的句子中，謂語部分的結構是be + p.p.（過去分詞）。被動語態(tài)的句子有時態(tài)的變化，這個變化反映在be動詞上。也就是說，把一個句子做成被動語態(tài)的句子，只需要寫出be動詞的所需時態(tài)，再加上所給動詞的過去分詞就行了。當然，這只是指謂語部分而言。我們知道，be動詞作為一個獨立的謂語動詞有自己現(xiàn)在分詞（being）和過去分詞 （been）。那么，下面我們來看看be在各種時態(tài)中的變化形式： 一般現(xiàn)在時 am / is / are 　　一般過去時 was / were 　　一般將來時 shall / will + be 　　過去完成時 had + been 現(xiàn)在進行時 am / is / are + being 過去進行時 was / were + being 現(xiàn)在完成時 have / has + been 過去將來時 would / should + be 說明： 　　1）以上的八個時態(tài)可用于被動式，其它沒有列舉的時態(tài)都不宜用于被動語態(tài)的句子中。 　　2）另外，表中被斜線隔開的詞表示根據具體情況作選擇。弄清楚了be在各種時態(tài)中的變化形式以后，我們就能很輕松地寫出被動語態(tài)的各種時態(tài)了。 　　　 我們可看看下面的實例： 　　 　English is spoken in many countries all over the world .（一般現(xiàn)在時） 　　 　世界上許多國家都講英文。 　　 　Some TV sets for sale in the department store were stolen last night. 　　 　那家商場用來出售的部分電視機昨晚被盜。（一般過去時） 　　 　He wont be allowed, by his father, to marry Laura. （一般將來時） 　　 　他父親不會讓他娶勞拉為妻的。 　　 　They would be sent to the army when they finished the training.　　 　 他們結束訓練時將被派往部隊。（過去將來時） 　　 　The project is being carried out.（現(xiàn)在進行時） 　　 　這個計劃正在執(zhí)行中。 　　 　The case was being investigated then.（過去進行時） 　　 　那時這案子正在調查中。 　　 　This novel has been translated into several languages. 　　 ?。ìF(xiàn)在完成時）這本小說已被譯成了幾種語言。 　　 　They said that production costs had been reduced. 　　 ?。ㄟ^去完成時）他們說生產成本已經下降了。 2. be used for 被用來做… 　What is the book used for?　　　 　　書是用來做什么的？　　 　　 　The book is used for reading.　　 　 書是用來讀的 　　 　The plane is used for traveling.　　 飛機是用來旅行的 3. according to 根據，按照 4. in this way 這樣 5. give sb. some time to do sth　 給某人一些時間做某事. 　The teacher gives the student two hours to do homework. 老師給同學們兩個小時做作業(yè)。 6. help sb. do sth.　 幫助某人做某事　 　I’ll help you leave the island.　 我將幫助你離開島嶼。 7. by accident 偶然的　 　by mistake 錯誤的 8. fall into 落入，陷入 9. in the end= at last=finally 最后 10. make　 sb. adj. 使某人…make me happy　　 使我開心 11. sb. called\named …　 被叫作，被稱作 a chef called Black.　　 一個叫布萊克的廚師 a doctor named Amy　　 一個叫艾米的醫(yī)生 12. sprinkle a lot of salt on chips　　 在薯片上灑大量的鹽 13. decide to do sth.　　　 決定做某事 I decide to taste the hot tea　 我決定品嘗熱茶。 14. not…until　 直到…才 You can’t leave until I arrive.　　　　　　 直到我到了你才能走。 　　I can’t watch TV until I finish my homework. 到我完成作業(yè)，我才能看電視。 15. be discovered in　 年代　　　be discovered in　 地方 The tea was discovered in China in 1610.　 茶是在1610年在中國被發(fā)現(xiàn)的。 16. over three thousand years　 三千年以上 17. produce a pleasant smell　　 產生一股令人愉快的氣味 18. over an open fire.　　　　 在明火上 19. in sixth century　　在第六世紀　 in nineteenth century.　　在十九世紀 練習： 一、根據開頭字母，補全單詞 1.
