  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 后接的一個分句做i think 的賓語,這個分句稱叫做賓語從句.

  (2)was invented 是被動語態(tài).

  (3)invent 做動詞,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”

  例如:edison was a great inventor, 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 enough.這個顧客說菜不夠咸.

  (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,從句也要用過去的某種時態(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應(yīng)后置.如:

  the little child was not old enough to go to school.這個小孩太小了,不能去上學(xué).

  但enough 修飾名詞時,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.)

  4.the potato chips were invented by mistake.由于錯誤,薯片被發(fā)明了.

  mistake 做名詞,意為 “弄錯,誤解”如:

  you have made a foolish mistake.你犯了一個愚蠢的錯誤.

  mistake 作動詞,意為 “弄錯,誤解”如:

  she didn’t speak very clearly so i mistook what she said.她講的不清楚,所以我誤解了她的話.

  by mistake 意為 “錯誤地,弄錯地”.

  i took his backpack by mistake. 我錯拿了他的書包.

  he put salt in her cup of tea by mistake.他錯把鹽放進(jìn)她的茶里.

  5.although tea wasn’t brought to the western world until 1610, this beverage was discovered over three thousand years before that.雖然,茶直到16XX年才傳入西方世界,但是這種飲料在三千多年前就被發(fā)現(xiàn)了.

  (1)although 作連詞,意為 “雖然,盡管”,引導(dǎo)讓步狀語從句,我們不能根據(jù)漢語習(xí)慣.在后面使用連詞but,不過它可以與yet, still連用;若主從句的主語相同,且從句謂語含有動詞be,可將從句主語和動詞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) not…until 意為 “直到……才”until 引導(dǎo)一個時間狀語從句.如

  he didn’t go to bed until his father came home.直到他爸爸回家時他才睡覺.

  6.according to an ancient chinese legend, the emperor shen nung discovered tea when he was boiling drinking water over an open air.

  根據(jù)中國古代的一個傳說, 神農(nóng)帝在戶外的火上燒飲用水時發(fā)現(xiàn)了茶葉.

  (1) according to 是個短語介詞,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, 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間.

  (1) leaf的復(fù)數(shù)形式為leaves

  (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.

  三、語法知識

  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(guān)系:

  1)當(dāng)句子的主語是謂語動作的執(zhí)行者時,主、謂之間的關(guān)系稱為主動語態(tài);

  2)當(dāng)句子的主語是謂語動作的承受者時,主、謂之間的關(guān)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(jié)構(gòu)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(dāng)然,這只是指謂語部分而言。我們知道,be動詞作為一個獨(dú)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

  過去將來時 would / should + be

  現(xiàn)在進(jìn)行時 am / is / are + being

  過去進(jìn)行時 was / were + being

  現(xiàn)在完成時 have / has + been

  過去完成時 had + been

  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,供根據(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(shí)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. (一般過去時)

  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 larra. (一般將來時)

  他父親不會讓他娶拉拉為妻的。

  they would be sent to the army when they finished the training. (過去將來時)

  他們結(jié)束訓(xùn)練時將被派往部隊。

  the project is being carried out.(現(xiàn)在進(jìn)行時)

  這個計劃正在執(zhí)行中。

  the case was being investigated then.(過去進(jìn)行時)

  那時這案子正在調(diào)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。
