主要語(yǔ)言點(diǎn)
In 1929, three years after his flight over the North Pole, the American explorer, R. E. Byrd, successfully flew over the South Pole for the first time. 1)three years after his flight over the North Pole用作1929的同位語(yǔ)，補(bǔ)充說(shuō)明在這一年發(fā)生的事情。the North Pole，北極，注意首字母要大寫(xiě)。 2)R. E. Byrd用作explorer的同位語(yǔ)。注意英語(yǔ)里的名字經(jīng)常可以縮略為大寫(xiě)首字母，右下角加上句點(diǎn)，但姓氏一般不能縮略。 3)successfully，源自succeed，名詞為success。 4)the South Pole，南極。 5)for the first time，首次、第。
Though, at first, Byrd and his men were able to take a great many photographs of the mountains that lay below, they soon ran into serious trouble. 1)at first，起初、一開(kāi)始。與后面的soon形成先后順序的呼應(yīng)。 2)take photographs，拍照。 3)a great many，許多、大量。只能用來(lái)修飾可數(shù)名詞。 4)mountain，山脈。注意與hill(丘陵)的區(qū)別。 5)lie，位于。其過(guò)去式和過(guò)去分詞分別為lay和lain。注意當(dāng)lie表示撒謊時(shí)，其過(guò)去式和過(guò)去分詞都是lied。 6)run into，遇到、陷入。后面一般都接difficulty或trouble等表示問(wèn)題或麻煩的詞語(yǔ)。 7)serious，嚴(yán)重的。
At one point, it seemed certain that their plane would crash. 1)at one point，在某個(gè)地方。 2)it seems certain that...，可以作為常用句型來(lái)用，表示什么事情似乎肯定會(huì)發(fā)生。 3)crash，墜毀。
It could only get over the mountains if it rose to 10,000 feet. 1)get over，超越、越過(guò)。 2)rise to+高度，表示上升到什么高度。
Byrd at once ordered his men to throw out two heavy food sacks. 1)at once在此提前到ordered前面，既可以起到強(qiáng)調(diào)作用，又可以避免放到句末引起歧義，讓讀者誤以為at once是用來(lái)修飾throw out的。 2)order sb. to do sth.，命令某人做某事。 3)throw out，扔出去。 4)sack，袋子。一般是指紙袋或塑料袋。
The plane was then able to rise and it cleared the mountains by 400 feet. 1)rise，爬升。 2)clear，越過(guò)。相當(dāng)于fly over。 3)by 400 feet，在山脈上空400英尺處。
Byrd now knew that he would be able to reach the South Pole which was 300 miles away, for there were no more mountains in sight. 1)reach，到達(dá)。相當(dāng)于get to或arrive at。 2)注意本句話中的which引導(dǎo)的是限定性定語(yǔ)從句，用來(lái)修飾先行詞the South Pole。但是，因?yàn)閠he South Pole具有性，所以只能被非限定性定語(yǔ)從句修飾，所以應(yīng)該要在Pole后面加上逗號(hào)，使得which引導(dǎo)的從句變?yōu)榉窍薅ㄐ缘亩ㄕZ(yǔ)從句。 3)for，因?yàn)?。它引?dǎo)的句子是并列句，表原因，只能放在后面，不能位于句首。 4)no more，相當(dāng)于not...any more。 5)in sight，視線所及。
The aircraft was able to fly over the endless white plains without difficulty. 1)aircraft，飛機(jī)。相當(dāng)于plane。 2)endless，無(wú)邊無(wú)際的、無(wú)盡的。源自end，-less是常見(jiàn)的否定后綴。 3)plain，平原。注意與plateau(高原)的區(qū)別。 4)without difficulty，毫不費(fèi)力地、輕松地。

重要句型或語(yǔ)法
1、動(dòng)名詞
與第20課側(cè)重“動(dòng)詞+動(dòng)名詞”的用法不同的是，本課新增了“介詞+動(dòng)名詞”、同一動(dòng)詞后接不定式和動(dòng)名詞、主動(dòng)表被動(dòng)的用法。如：
Both men started running through the trees.
The strap needs mending.
I am very keen on cycling.
He sat there without saying anything.
I must apologize for not letting you know earlier.
They continued to run. vs. They continued running.
I'd love to sit in the garden. vs. I love sitting in the garden when it's fine.
2、結(jié)果狀語(yǔ)從句
本課里出現(xiàn)了so/such...that...引導(dǎo)的結(jié)果狀語(yǔ)從句，如：
Mrs. Sterling got so angry that she ran after them.
The men got such a fright that they dropped the bag and ran away.
課文主要語(yǔ)言點(diǎn)
Mrs. Anne Sterling did not think of the risk she was taking when she ran through a forest after two men. 1)think of，想到。注意與think about(思考的區(qū)別。 2)注意she was taking是先行詞the risk的定語(yǔ)從句，中間省略了關(guān)系代詞that或which。 3)take a risk，冒險(xiǎn)。注意risk也可以作為動(dòng)詞，表示冒險(xiǎn)，如：risk doing sth.，冒險(xiǎn)做某事;risk one's life for sth.，為了某事冒著生命的危險(xiǎn)。 4)注意在when she ran through a forest after two men中，ran后面原本應(yīng)該先緊接after two men的，因?yàn)閞un after是固定搭配，表示追趕。但是，作者卻在中間插入了through a forest，這是出于對(duì)下一句話銜接的需要，因?yàn)樽髡呦胍磉_(dá)的重點(diǎn)就是two men，下一句話的開(kāi)頭中的they指的就是two men。 5)through a forest，穿過(guò)森林。注意從某地方內(nèi)部或里面穿過(guò)，一般用through，如果從某地方表面穿過(guò)，一般用across。
They had rushed up to her while she was having a picnic at the edge of a forest with her children and tried to steal her handbag. 1)可提問(wèn)學(xué)生為什么此處的rush要采用過(guò)去完成時(shí)(因?yàn)檫@句話是基于上一句話的過(guò)去時(shí)間來(lái)講的，rush的動(dòng)作發(fā)生在think of之前，即過(guò)去的過(guò)去)。 2)rush up to sb.，向某人沖過(guò)去。 3)have a picnic，野餐。注意picnic的發(fā)音，第一個(gè)c會(huì)發(fā)生爆破音的消失現(xiàn)象;此外，picnic也可以用作動(dòng)詞，其現(xiàn)在分詞為picnicking。 4)at the edge of，在...邊緣。 5)注意區(qū)分try to do(努力做)與try doing(嘗試做)的區(qū)別。 6)注意steal(偷)與rob(搶)的區(qū)別。注意steal的過(guò)去式和過(guò)去分詞為stole何stolen。
In the struggle, the strap broke and, with the bag in their possession, both men started running through the trees. 1)struggle，掙扎、斗爭(zhēng)。 2)with the bag in their possession在此用作插入語(yǔ)，表示伴隨。這是一種獨(dú)立主格結(jié)構(gòu)，即“with+名詞+介詞短語(yǔ)”的結(jié)構(gòu)。 3)possession是possess的名詞。in one's possession，擁有、掌握。 4)start to do和start doing用法差不多，但要注意動(dòng)名詞一般表示動(dòng)作會(huì)持續(xù)下去，而不定式則只表示動(dòng)作的開(kāi)始。
Mrs. Sterling got so angry that she ran after the them. 1)注意so...that...引導(dǎo)的結(jié)果狀語(yǔ)從句，so用來(lái)修飾形容詞或副詞。 2)注意get angry與be angry相比，動(dòng)作含義更強(qiáng)，所以作者采用了get angry的表達(dá)，來(lái)突出Mrs. Sterling非常生氣。
She was soon out of breath, but she continued to run. 1)out of breath，上氣不接下氣、急喘氣。 2)continue to do和continue doing意思和用法都差不多，表示繼續(xù)做某事。
When she caught up with them, she saw that they had sat down and were going through the contents of the bag, so she ran straight at them. 1)catch up with，追上、趕上。 2)注意因?yàn)閟aw是過(guò)去式，所以其賓語(yǔ)從句的謂語(yǔ)動(dòng)詞sit采用了過(guò)去完成時(shí)的用法。 3)go through，翻看、查看。 4)content，內(nèi)容、物品、目錄。 5)run straight at sb.，徑直朝某人跑去。
The men got such a fright that they dropped the bag and ran away. 1)注意such...that...引導(dǎo)的結(jié)果狀語(yǔ)從句，such用來(lái)修飾名詞。 2)fright，害怕，用作名詞。其動(dòng)詞形式為frighten。 3)drop，丟棄、丟掉。注意其過(guò)去式要雙寫(xiě)p再加ed。 4)run away，逃跑。
The strap needs mending,' said Mrs. Sterling later, 'but they did not steal anything.' 1)注意本句中的sth need doing，是主動(dòng)表被動(dòng)的用法，相當(dāng)于sth. need to be done。類(lèi)似的用法有：sth. want doing，但此時(shí)的want doing不能改為want to be done的用法。 2)mend，修理、修補(bǔ)。

復(fù)習(xí)
本課為復(fù)習(xí)課，主要復(fù)習(xí)第10、第21和第34課中的重點(diǎn)語(yǔ)法內(nèi)容——被動(dòng)語(yǔ)態(tài)。其中，第10課側(cè)重的是不同時(shí)態(tài)中的被動(dòng)語(yǔ)態(tài)的用法，第21課側(cè)重的是情態(tài)動(dòng)詞與被動(dòng)語(yǔ)態(tài)的連用，第34課側(cè)重的是be done to do的用法。如：This bridge was built in 1942. / I must be paid for this. / I was told to wait for him.
課文主要語(yǔ)言點(diǎn)
1)The whole village soon learnt that a large sum of money had been lost. 1)the whole village，整個(gè)村莊。
2)learn，學(xué)習(xí)、得知。當(dāng)表示“學(xué)習(xí)”時(shí)，其過(guò)去式和過(guò)去分詞多為learned，而當(dāng)表示“得知”時(shí)，其過(guò)去式和過(guò)去分詞多為learnt。
3)a sum of，一筆。一般后接money。
4)可提問(wèn)學(xué)生為什么be lost要用過(guò)去完成時(shí)。另外，要注意的是，此處的lost是形容詞化的過(guò)去分詞。
Sam Benton, the local butcher, had lost his wallet while taking his savings to the post office.
1)the local butcher，當(dāng)?shù)氐娜怃伬习?。該短語(yǔ)在句中用逗號(hào)隔開(kāi)，作為Sam Benton的同位語(yǔ)，補(bǔ)充說(shuō)明其身份。 local，當(dāng)?shù)氐摹?BR> 2)注意taking his savings to the post office中的taking...其實(shí)是省略結(jié)果，其完整形式為while he was taking。之所以能夠省略，是因?yàn)榍昂髢删湓挼闹髡Z(yǔ)是相同的，都是the butcher。
3)注意savings一定要用s形式才能表存款。 4)注意給學(xué)生介紹，郵局也有儲(chǔ)蓄功能，即便在沒(méi)有郵儲(chǔ)銀行之前，郵局也有過(guò)儲(chǔ)蓄的功能。所以，課文里會(huì)說(shuō)到the butcher帶著儲(chǔ)蓄去郵局的情節(jié)。
Sam was sure that the wallet must have been found by one of the villagers, but it was not returned to him.
1)be sure that...，肯定...。that后接賓語(yǔ)從句。
2)return sth. to sb.，把某物歸還某人。
Three months passed, and then one morning, Sam found his wallet outside his front door.
1)“時(shí)間段+passed, and then...”可以用作常用句型，表示“過(guò)了多長(zhǎng)時(shí)間后，事情發(fā)生了。
2)注意區(qū)分passed(動(dòng)詞，經(jīng)過(guò))和past(介詞，經(jīng)過(guò))。
It had been wrapped up in newspaper and it contained half of the money he had lost, together with a note which said: 'A thief, yes, but only 50 percet a thief!'
1)wrap up，打包、包裹。
2)contain，包含、含有。
3)注意he had lost用作money的定語(yǔ)從句，中間省略了that/which。
4)together with sb.，與某人一起。
5)which said...用作note的定語(yǔ)，注意said表示“寫(xiě)著”。
6)per cent，百分之...。注意也可以連起來(lái)寫(xiě)作：percent。
Two months later, some more money was sent to Sam with another note" 'Only 25 per cent a thief now!'
1)時(shí)間段+later，多少時(shí)間之后。
2)another，另一個(gè)、在一個(gè)。也可以后接附復(fù)數(shù)可數(shù)名詞。
In time, all Sam's money was paid back in this way.
1)in time，后、終于。
2)pay back，償還。
The last note said: "I am 100 per cent honest now!" honest，誠(chéng)實(shí)的。注意honest的h不發(fā)音。
