2019-2020年九年級(jí)英語(yǔ) Unit 9When were they invented教案 人教新目標(biāo)版 一、學(xué)習(xí)目標(biāo)： 掌握一般現(xiàn)在時(shí)、一般過(guò)去時(shí)和含有情態(tài)動(dòng)詞的被動(dòng)語(yǔ)態(tài)的用法。 二、語(yǔ)法介紹： 英語(yǔ)中動(dòng)詞的語(yǔ)態(tài)分成兩種：主動(dòng)語(yǔ)態(tài)和被動(dòng)語(yǔ)態(tài)。當(dāng)句子的主語(yǔ)是動(dòng)作的執(zhí)行者時(shí)，謂語(yǔ)的形式叫主動(dòng)語(yǔ)態(tài)；當(dāng)句子的主語(yǔ)是動(dòng)作的承受者時(shí)，謂語(yǔ)要用被動(dòng)語(yǔ)態(tài)。 ㈠含義：動(dòng)詞的被動(dòng)語(yǔ)態(tài)一般譯成“被…”，但是根據(jù)漢語(yǔ)表達(dá)習(xí)慣，有時(shí)“被”也可以不譯出。 ㈡構(gòu)成：被動(dòng)語(yǔ)態(tài)一般的構(gòu)成形式為:be+動(dòng)詞過(guò)去分詞（+by+動(dòng)作的發(fā)出者）。其中助動(dòng)詞be有人稱、數(shù)和時(shí)態(tài)的變化。 一般現(xiàn)在時(shí):am/is/are+done(過(guò)去分詞) 一般過(guò)去時(shí)：was/were+done(過(guò)去分詞) 含有情態(tài)動(dòng)詞的：情態(tài)動(dòng)詞+be+done(過(guò)去分詞) ㈢方法： 1、將主動(dòng)語(yǔ)態(tài)句中的賓語(yǔ)變?yōu)楸粍?dòng)語(yǔ)態(tài)句中的主語(yǔ)，主動(dòng)語(yǔ)態(tài)句中的主語(yǔ)變?yōu)楸粍?dòng)語(yǔ)態(tài)句中介詞by的賓語(yǔ)。 2、將主動(dòng)語(yǔ)態(tài)句中謂語(yǔ)動(dòng)詞變成:助動(dòng)詞be+該動(dòng)詞的過(guò)去分詞，但時(shí)態(tài)不改變。 3、助動(dòng)詞be要與新的主語(yǔ)保持單、復(fù)數(shù)一致；若主語(yǔ)和賓語(yǔ)是人稱代詞時(shí)，“格”應(yīng)作相應(yīng)的變化。 口訣：賓變主，主變賓，謂變be done時(shí)不變，數(shù)格必須隨著變。 The workers make machines in this factory. Machines are made by the workers in this factory. 注意：不及物動(dòng)詞沒(méi)有被動(dòng)語(yǔ)態(tài)。 ㈣例句： 1.Many people speak English in China. English is spoken by many people in China. 2.Bell invented the telephone in 1876. The telephone was invented by Bell in 1876. 3.We must look afer the old man. The old man must be looked after (by us). ㈤特殊情況： ⑴（含有雙賓語(yǔ)的句子變被動(dòng)語(yǔ)態(tài)） 剖析：含雙賓語(yǔ)的主動(dòng)語(yǔ)態(tài)的句子變?yōu)楸粍?dòng)語(yǔ)態(tài)時(shí)，常把那個(gè)指人的間接賓語(yǔ)變?yōu)楸粍?dòng)語(yǔ)態(tài)的主語(yǔ)；也可把那個(gè)指物的直接賓語(yǔ)用作主語(yǔ)，但此時(shí)必須在間接賓語(yǔ)前加上介詞to或for。如： He gave me a book. →I was given a book by him. →A book was given to me by him. 口訣：如遇雙賓語(yǔ)，一般變間賓。若把直賓變，to,for間賓連。 ⑵感官動(dòng)詞和使役動(dòng)詞在主動(dòng)句中其后的動(dòng)詞不定式不帶to，但變被動(dòng)句時(shí)必須加上to。如： The boss made her work for 16 hours a day. →She was made to work for 16 hours a day. 口訣：感/使動(dòng)詞真叫怪，to來(lái)to去記心懷，主動(dòng)語(yǔ)態(tài)to離去，被動(dòng)語(yǔ)態(tài)to回來(lái)。 三、對(duì)應(yīng)練習(xí)： ㈠選擇填空 1.
