6、xth century在第六世紀(jì)in nineteenth century.在十九世紀(jì)三、知識點(diǎn)講解1.I think the telephone was invented before the car. 我認(rèn)為電話在汽車之前發(fā)明的。(1) I think 后接的一個(gè)分句做 I think 的賓語 ,這個(gè)分句稱叫做賓語從句。(2)was invented 是被動(dòng)語態(tài) .(3)invent 做動(dòng)詞 ,意為 “發(fā)明 ,創(chuàng)造 ”,其名詞有兩種形式:一種為 inventor發(fā)“明者 ”。一種為invention發(fā)明“ ,創(chuàng)造 ”2/21例如 :Edison was a great inventor,

7、he invented more than 1,000 inventions in his life.2.It s used for scooping really cold ice cream它是.用來舀十分冰冷的冰淇淋的.句型 be used for 意為“被用來做 ”,介詞 for 表示用途 ,后接名詞或動(dòng)名詞。如 :(1) sweater is used for keeping warm. 毛衣是用來保暖的。(2) The knife is used for cutting. 小刀是用來切削東西的。3.The custom said they weren t salty這enough個(gè)

8、顧客.說菜不夠咸。(1)said 后是賓語從句 ,省略了 that.當(dāng)賓語從句主句用一般過去時(shí),從句也要用過去的某種時(shí)態(tài)。如 :He asked me whom I was waiting for.他問我在等誰.(2)enough 修飾形容詞或副詞時(shí)應(yīng)后置. 如 :The little child was not old enough to go to school.這個(gè)小孩太小了,不能去上學(xué) .但 enough 修飾名詞時(shí) ,可以放在名詞之前,也可以放在名詞之后。如:I have enough money to buy it.( I have money enough to buy it.)

11、ll 連用。若主從句的主語相同,且從句謂語含有動(dòng)詞be,可將從句主語和動(dòng)詞be 省略 .如:Although (it was)snowing, it was not very cold.雖然在下雪 ,但是天氣不是很冷.There is air around us, although we can t see it.盡管我們看不見,但是我們周圍全是空氣.Although (he is) quite young, he knows a lot.雖然他很年輕,但是他很懂事 .(3)notuntil 意為 “直到才 ” until引導(dǎo)一個(gè)時(shí)間狀語從句.如4/21He didn t go to bed

12、until his father came home直.到他爸爸回家時(shí)他才睡覺.6.According to an ancient Chinese legend, the emperor Shen Nong discovered tea when he wasboiling drinking water over an open air.根據(jù)中國古代的一個(gè)傳說, 神農(nóng)帝在戶外的火上燒飲用水時(shí)發(fā)現(xiàn)了茶葉.(1) According to 是個(gè)短語介詞 ,意為 “根據(jù) 。依照 ”后接代詞 ,名詞或由疑問詞以及 whether 引出的名詞性從句 .如 :According to the radio,

13、 it will rain tomorrow.根據(jù)收音機(jī)說 ,明天有雨 .According to what you said just now, he was right then.根據(jù)你剛才說的,那么他就對了.(2) 介詞 over 在此意為 “在 正上方 ”而介詞 above 指 “在 的上方 ”。介詞 on 指“在的上面 ”7.Some leaves from a nearby bush fell into the water and remained there for some time.一些葉子從附近的灌木叢落到水里.并在水里浸泡了一段時(shí)間.(1) leaf 的復(fù)數(shù)形式為 lea

14、ves(2) remain 表示 “繼續(xù)留在某處 ”如How long will you remain here?你要在此地停留多久?(3) fall into落入“,陷入 ”如:He was drunk and fell into the water. 他酒醉跌落水中.5/21三、語法知識1. 被動(dòng)語態(tài)謂語動(dòng)詞的語態(tài)表示句子的主語和謂語動(dòng)作之間的關(guān)系：1）當(dāng)句子的主語是謂語動(dòng)作的執(zhí)行者時(shí)，主、謂之間的關(guān)系稱為主動(dòng)語態(tài)；2）當(dāng)句子的主語是謂語動(dòng)作的承受者時(shí)，主、謂之間的關(guān)系稱為被動(dòng)語態(tài)。例如：I teach English. （主動(dòng)語態(tài)）我教英語。Our English is taught b

15、yhim. （被動(dòng)語態(tài)）我們的英語是由他教的。He speaks English.（主動(dòng)語態(tài)）他說英文。English is spoken in many countries all over the world.（被動(dòng)語態(tài)）世界許多國家都講英語。在被動(dòng)語態(tài)的句子中，謂語部分的結(jié)構(gòu)是be + p.p. （過去分詞）。被動(dòng)語態(tài)的句子有時(shí)態(tài)的變化，這個(gè)變化反映在be 動(dòng)詞上。也就是說，把一個(gè)句子做成被動(dòng)語態(tài)的句子，只需要寫出 BE 動(dòng)詞的所需時(shí)態(tài)，再加上所給動(dòng)詞的過去分詞就行了。當(dāng)然，這只是指謂語部分而言。我們知道， be 動(dòng)詞作為一個(gè)獨(dú)立的謂語動(dòng)詞有自己現(xiàn)在分詞（being）和過去分詞（ bee

16、n）。那么，下面我們來看看be 在各種時(shí)態(tài)中的變化形式：一般現(xiàn)在時(shí)am / is / are一般過去時(shí)was / were一般將來時(shí)shall / will + be過去將來時(shí)would / should + be現(xiàn)在進(jìn)行時(shí)am / is / are + being過去進(jìn)行時(shí)was / were + being現(xiàn)在完成時(shí)have / has + been過去完成時(shí)had + been說明： 1）以上的八個(gè)時(shí)態(tài)可用于被動(dòng)式，其它沒有列舉的時(shí)態(tài)都不宜用于被動(dòng)語態(tài)的句子中。2）另外，表中被斜線隔開的詞表示，供根據(jù)具體情況作選擇。弄清楚了be 在各種時(shí)態(tài)中的變化形式以后，我們就能很輕松地寫出被動(dòng)語態(tài)的

17、各種時(shí)態(tài)了。我們可看看下面的實(shí)例：English is spoken in many countries all over the world .（一般現(xiàn)在時(shí)）世界上許多國家都講英文。Some TV sets for sale in the department store were stolen last night. （一般過去時(shí)）6/21那家商場用來出售的部分電視機(jī)昨晚被盜。He won't be allowed , by his father, to marry Mary.（一般將來時(shí)）他父親不會讓他娶瑪麗為妻的。They would be sent to the army w

18、hen they finished the training.（過去將來時(shí)）他們結(jié)束訓(xùn)練時(shí)將被派往部隊(duì)。The project is being carried out.（現(xiàn)在進(jìn)行時(shí)）這個(gè)計(jì)劃正在執(zhí)行中。The case was being investigated then.（過去進(jìn)行時(shí)）那時(shí)這案子正在調(diào)查中。This novel has been translated into several languages.（現(xiàn)在完成時(shí)）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(shí)）他們說生產(chǎn)成本已經(jīng)下降了
