1、滬教牛津版七年級上Unit3 The Earth單元目標(biāo)：1.學(xué)會使用可數(shù)名詞和不可數(shù)名詞。 2There is/ are 的基本用法。 3.掌握本單元的重點詞匯。核心詞匯：Earth 地球 quiz 小測試 pattern 模式 protect 保護 report 報告 part 部分 land 陸地 field 田地 large 大的 provide 提供 pollution 污染 burn 燃燒 energy 能源 pollute(動詞) 污染 ground 地面 kill 殺死 important 重要的 fact 事實 kilometer 公里 own 擁有 catch 捕捉 pro

2、blem問題 重要短語:protect tne Earth 保護地球 provide.with為.提供 make energy 制造能源 put.into把.倒入stop doing sth停止做某事 throw away扔掉常考句型：1. There are forests and rivers, mountains and fields. (地球上)有森林和河流，山脈和田野。 注：there be 結(jié)構(gòu)常用來表示“某時或某地有某人或某物”，其形式為“there be +名詞+地點狀語+時間狀語”，其中be動詞為謂語動詞，它的形式應(yīng)與緊跟其后面做主語的名詞保持人稱和數(shù)的一致。 例：There

3、 is a desk and four chairs in the room. 房間里有一張桌子和四把椅子。There are four chairs and a desk in the room.房間里有四把椅子和一張桌子。析: There be 結(jié)構(gòu)與have(1)There be結(jié)構(gòu)強調(diào)“存在關(guān)系”，而have強調(diào)“所屬關(guān)系”。如. There is a boat in the river. 河里有一條船。I have a nice watch. 我有一塊好看的手表。(2)表示“有”時，there be 結(jié)構(gòu)不能與行為動詞have連用，在表示“附屬于某物/某地的東西”時，there be

4、結(jié)構(gòu)可以與have替換。如：下周三有個班會。There is going to have a class meeting next Wednesday. (錯)There is going to be a class meeting next Wednesday. (對)教室墻上有四扇窗戶。There are four windows in the wall of the classroom.= The classroom has four windows in the wall.2. All plants need light and water.所有的植物都需要陽光和水。注：need在這為

5、實義動詞，可用于各種句型，有人稱和數(shù)的變化。Need也可作情態(tài)動詞，但僅用于否定句或疑問句中，后接動詞原形。例：Does he need to hand in his examination paper now?他需要現(xiàn)在交卷嗎？-Must I finish my homework now?我必須先在完成我的作業(yè)嗎？-No，you neednt.不，不需要。3.There are also many people like you and me on Earth.地球上也有很多像你我一樣的人。注：also, 副詞。意為“也”。例：Tom is going to Canada, Linda is

6、 also going to Canada.湯姆打算去加拿大，琳達(dá)耶也打算去。析：also,too和either三者都表示“也”，其中also和too可以替換，都可以用于肯定句和疑問句，但位置不同。also常放在實義動詞前，be動詞、連系動詞后面；too常放在句末，too前面要加逗號。either只用于否定句。例：She plays the piano and sings, too. =She plays the piano and also sings. 她會彈琴也會唱歌。 I dont like the pink one, I dont like the red one either. 我

7、不喜歡那個粉色的，我也不喜歡那個紅色的。3. Its important for us to protect the Earth for our future.為了我們的未來，保護地球很重要。 注:It在句中作形式主語，整整的主語為不定式to protect the Earth.動詞不定式作主語，可以放在句前也可以放在句后。 句中的謂語動詞用單數(shù)。語法專講：名詞的數(shù)：名詞按其所表示的事物的性質(zhì)可分為可數(shù)名詞和不可數(shù)名詞兩類?？蓴?shù)名詞有復(fù)數(shù)形式。不可數(shù)名詞一般沒有復(fù)數(shù)形式?？蓴?shù)名詞的單數(shù)往往要與補丁冠詞a或an連用，復(fù)數(shù)則使用其復(fù)數(shù)形式。1 可數(shù)名詞的單復(fù)數(shù)1. 單數(shù)可數(shù)名詞表示名詞的單數(shù)，要在

8、名詞前加不定冠詞a或an. a加載以輔音開頭的名詞前，an加在以元音開頭的名詞前。如： a book an apple 2. 復(fù)數(shù)可數(shù)名詞 名詞的復(fù)數(shù)形式是在單數(shù)名詞后加上-s或“-es構(gòu)成的，其復(fù)數(shù)的一半構(gòu)成方法如下表：情況 構(gòu)成方法 例詞一般情況 在詞尾加sdesk-desksgirl-girls以s,x,ch,sh結(jié)尾的詞在詞尾加-esbus-busesFish-fishes以輔音字母加y結(jié)尾的詞變y為i再加-esFamiliesParty-parties以元音字母加y結(jié)尾的詞在詞尾加-sDay-daysKey-keys以f或fe結(jié)尾的詞變f或fe為v再加-esKnife-knivesW

9、ife-wives 以輔音字母加o結(jié)尾的詞在詞尾加-esPotato-potatoesHero-heroes 以元音字母加-o結(jié)尾的詞在詞尾加-sRadio-radiosZoo-zoos注意：（1）少數(shù)以輔音字母加o結(jié)尾的名詞變?yōu)閺?fù)數(shù)時只加-s。 如：photo-photos相片 piano-pianos鋼琴（2） 一些名詞的不規(guī)則變化a. 元音發(fā)生變化 man-men男人 woman-women女人 foot-feet腳 tooth-teeth牙b. 單復(fù)數(shù)形式相同Deer-deer鹿 fish-fish魚 sheep-sheep綿羊 Chinese-Chinese中國人c. 詞尾發(fā)生變化C

10、hild-children孩子 ox-oxen公牛d. 有些名詞只有復(fù)數(shù)形式Clothes衣服 trousers褲子 glasses眼鏡 scissors剪子2、 不可數(shù)名詞1. 不可數(shù)名詞的確切數(shù)量的表達(dá)方式當(dāng)表示不可數(shù)名詞的確切數(shù)量時，通?？稍诓豢蓴?shù)名詞前面加上表示數(shù)量的單位詞。a glass of water一杯水 two glasses of water兩杯水A kilo of meat一公斤肉 two kilos of meat兩公斤肉2. 不可數(shù)名詞的不確切數(shù)量的表達(dá)方式當(dāng)表示不可數(shù)名詞的各種大概、不確切的數(shù)量時，課運用下列單詞和短語：單詞：not (any) / no沒有 lit

11、tle幾乎沒有 a little / some一些 most大部分， all全部 短語：a lot of / lots of /plenty of / much / a great deal of/. 許多There be結(jié)構(gòu)There be結(jié)構(gòu)又叫存在句，它是英語中一種常見的句型結(jié)構(gòu)，表示“在某地存在某人或某物”。1、 there be 結(jié)構(gòu)的肯定式2、 There be結(jié)構(gòu)的主謂一致（就近原則）3、 There be結(jié)構(gòu)的疑問式4、 There be 結(jié)構(gòu)的否定式。課后練習(xí)：I.根據(jù)句意及首字母提示完成單詞 1.They went for walks together in the f_.
