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inventadjustable heel battery operate slipper scoopelectricbulb microwaveoven islandsweetsalty crispy sour potatochip mistake thin chef sprinklebeverage thousand accordingancient legend emperor boil fire leaf nearby remainnoticeproduce pleasantsmell taste metal pie bakerythrow special abacus century telescope camera term2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？ -Theyre 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(jù)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. （現(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. （過去完成時）他們說生產(chǎn)成本已經(jīng)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(jù)，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Ill 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. callednamed 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. notuntil 直到才You cant leave until I arrive. 直到我到了你才能走。I cant 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(chǎn)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(jù)開頭字母，補全單詞1.
