二、重點(diǎn)與難點(diǎn)
L.53
1. I feel like going to a museum . 我想去參觀博物館。
此句中的短語動(dòng)詞feel like作“想（做某事）”、“愿意”、“感到象是……樣子”解，它表示主觀上的想法，后面跟名詞或動(dòng)名詞形式。例如：
I’m hungry , I feel like eating something . 我餓了，我想吃點(diǎn)什么東西。
She didn’t feel like going to see a film that moment , for she had too much homework to do .
那時(shí)她不想去看電影，因?yàn)樗性S多作業(yè)要做。
Do you feel like coffee or soft drink ? 你想喝咖啡還是飲料？
表示“想要做某事”的意思時(shí)，本課中還出現(xiàn)了 “would like to do sth” “plan to do sth”和would rather do sth .例如：
I’d like to visit the History Museum . 我想?yún)⒂^歷史博物館。
What are you planning to do this Sunday ? 你打算星期日做什么？
I’d rather stay at home . 我寧愿呆在家里。
2.So far as I know , it’s free . 據(jù)我所知，那個(gè)博物館是不收門票的。
a)句中的so / as far as I know作插入語，與句子中的其它部分關(guān)系不密切，通常用逗號(hào)分開，其意思是“就我所知”。另外，so / as far as通常引出一個(gè)分句，意思為“就……而言”，“盡……”，“至于……”，“到某種程度”。例如：
So / As far as I know , we won’t be late , because we have plenty of time .
就我可知我們是不會(huì)晚的，因?yàn)槲覀冇凶銐虻臅r(shí)間。
As far as he is concerned , he can’t offord such an expensive car .
就他而言，他買不起如此昂貴的車。
He promised to help me as far as he could . 他答應(yīng)要盡力地幫助我。
b)此句中的free意思是“免費(fèi)的”，“免稅的”。例如：
It’s free of charge and you don’t need to pay it .
這是免費(fèi)的，因此你不必付錢。
Does everyone in this country enjoy free medical care ?
這個(gè)國家的每個(gè)人都享受免費(fèi)醫(yī)療嗎？
3.Personally , I’d rather go to the Science Museum .
就我個(gè)人來說，我倒想去科學(xué)博物館。
此處的personally是副詞，意思是“就自己而言”，“就個(gè)人來說”，相當(dāng)于Speaking for myself或as far as I am concerned . 例如：
Personally , I agree with you . 就我個(gè)人來說，我還是贊同你的。
She said she disliked it , but personally I thought it was worth buying .
她說她不喜歡這個(gè)東西，但就我個(gè)人來說，我認(rèn)為值得買下來。
除此之外，personally一詞還有“親自地……”之意。例如：
The headmaster personally showed the guests around the school .
校長親自帶領(lǐng)來賓們參觀了學(xué)校。
4. They’ve got a special exhibition on this month .
他們這個(gè)月將舉辦一個(gè)特別的展覽會(huì)。
在此句中，have got…on相當(dāng)于have…on的意思，作“有（某項(xiàng)活動(dòng)）在進(jìn)行”解，這里的副詞on有“（某事）在發(fā)生或展示”的意思。例如：
What’s on tonight ? 今晚有什么活動(dòng)？
I’ve nothing on tonight ? 我今晚沒什么活動(dòng)。
I’m sorry I didn’t attend your party that night because I had a meeting on for that night .
對(duì)不起，那天晚上我沒有參加你的聚會(huì)，因我有個(gè)會(huì)。
L.54
1. To escape the pull of the earth , a rocket must reach a speed of 28.4400 km / h .
為擺脫地球的引力，火箭的速度達(dá)到每小時(shí)四萬公里。
a)句中的To escape the pull of the earth是動(dòng)詞不定式結(jié)構(gòu)，在句中作目的狀語，其作用同于In order to escape the pull of the earth .例如：
To master / In order to master English , you must practise every day .
為了精通英語，你應(yīng)該每天練習(xí)。
He worked day and night to finish his papers ahead of time .
為了提前完成論文，他日夜地工作。
b)這里要注意的是動(dòng)詞escape的用法，作為及物動(dòng)詞用時(shí)，后面跟名詞或動(dòng)名詞；作為不及物動(dòng)詞用時(shí)，后面跟介詞from，再加方位名詞。例如：
It is reported that two of the prisoners have escaped . 據(jù)報(bào)道兩個(gè)囚犯逃跑了。
A tiger escaped from the zoo . 一只老虎從動(dòng)物園跑了出來。
How can we escape the crowds ? 我們?nèi)绾伪荛_人群？
Those who break the law will not escape being punished .
觸犯了法律的人是逃脫不了懲罰的。
c)pull一詞在句中作名詞用，意思是“吸引力”，同gravity。例如：
It’s not easy to break away from the pull of the earth .
要擺接吻地球的吸引力不是那么容易的。
作動(dòng)詞用時(shí)，它還用“拉”，“托”，“拔”的意思。
Let’s go to the yard and pull up weeds . 咱們到院子里去拔草吧。
d)at a speed of表示“以……單位速度”，這時(shí)后面加速時(shí)的單位，speed一詞前面加不定冠詞。例如：
The car travels at a speed of 90 miles an hour .
小汽車以每小時(shí)80英里的速度行駛。
又如：You’ll find it’s a beautiful painting if you enjoy it at a distance of 3 metres .
如果你站在三米的距離以外來欣賞這幅畫，你就會(huì)覺得這是一幅漂亮的畫。
The plane is flying at a height of 10,000 metres .
飛機(jī)正在10,000米的高空飛行。
2.First , it must be light , the lighter the better , because it has to be sent up into space by a rocket .
首先，它必須很輕，越輕越好，因?yàn)樾l(wèi)星得用火箭把它送入太空。
“the lighter the better” 在句中是插入語，而且這是一個(gè)省略結(jié)構(gòu)，全句應(yīng)是這樣的，
The lighter the satellite is , the better it will be .這種結(jié)構(gòu)為：the + adj / adv .的比較級(jí) + the + adj / adv .的比較級(jí)，表示“越……，就越……”的意思。例如：
The more you read , the more you know . 你讀得越多，就知道的越多。
The more the better . 越多越好。
The sooner the better . 越快越好。
The higher it flies . the smaller it appears .它飛得越高，就顯得越小。
3.It has equipment for making electricity from sunshine , using very broad sun panels .
它有太陽能發(fā)電設(shè)備，用的是很寬大的太陽能電池帆板。
a)句中的make…from…的意思是“用……制成……”。它�？梢杂糜诓▌�(dòng)結(jié)構(gòu)，例如：
I made a table from this kind of material . (The table was made from this kind of material .)
我用這種材料做了一張桌子。
My mother made me a shirt from the material I didn’t like .
我媽媽用我不喜歡的面料給我做了一件襯衣。
b)equipment一詞是不可數(shù)名詞。如以下各句中：
A new factory with modern equipment will be built here .
在這里將要建一個(gè)具有現(xiàn)代化設(shè)備的工廠。
Radar equipment helps us a lot in our daily life .
雷達(dá)裝置在日常生活中頗有用處。
c)using very broad sun panels結(jié)構(gòu)是～ing短語形式，其作用是在句中用作方式狀語，修飾making electricity from sunshine。例如：
We Chinese eat our food , using chopsticks , while the westerners eat their food , using forks and Knives .
我們中國人用筷子吃東西，而西方人用刀子和叉子。
4.Once the satellite goes into its orbit round the earth , the panels are unfolded in order to catch the sunshine .
一旦衛(wèi)星進(jìn)入地球轉(zhuǎn)產(chǎn)，帆板就打下來吸收陽光。
a)once在句中是連詞，引導(dǎo)一個(gè)時(shí)間狀語從句，相當(dāng)于as soon as…，在這種從句中，也不用將來時(shí)態(tài)，而只用一般時(shí)或完成時(shí)。例如：
Once I decide to do something , I’ll try my best to do it well .
一旦我決定做什么事，我一定會(huì)盡力去把它做好。
Once we have gathered enough proof , we can accuse him at the court .
我們一旦得到足夠的證據(jù)，我們就可以在法庭上指控他。
A decision shouldn’t be changed once it is made .
一旦作出了決定，就不應(yīng)當(dāng)改變它。
另外，once還可以用作副詞，作“一次”，“曾經(jīng)一度”；“過去”解。例如：
I go to see my grandparents once a week . 我每星期去看我的祖父母一次。
The song was once very popular . 這首歌曾經(jīng)一度很流行。
b)動(dòng)詞unfold (展開)，它和fold (折疊)是一對(duì)反義詞。例如：
She opened the letter , unfolded it and than read it .
她拆開信封，把信折開然后讀了起來。
After reading the letter , she folded it and put it in the envelope again .
讀完信之后，她把信疊好，又放入信封。
在英語中，有不少動(dòng)詞可以用加前綴un- , dis- 的方法，構(gòu)成詞義相反的詞。如：
lock (上鎖) unlock (開鎖) like (喜歡) dislike (厭惡)
dress (穿衣服)undress (脫衣服) appear (出現(xiàn))disappear (消失)
5.They remain above the same place on the earth and travel round it in a very high circle .
它們（衛(wèi)星）保持在地面上周一位置的上方，在高空中環(huán)繞地球運(yùn)行。
句中的circle一詞是作為名詞用的，它還可以用作動(dòng)詞。名詞時(shí)其意為“圓”，“圈”，而作動(dòng)詞時(shí)，則作“環(huán)繞”，“傳播”解。例如：
The children were standing in a circle , playing games .
孩子們站成一個(gè)圈，做游戲。
The teacher asked his students to use their compasses to draw circles .
老師要求學(xué)生們用圓規(guī)畫圓。
He is well known in bussiness circle and has a large circle of friends .
他在商界是知名人士而且也有很多朋友。
The moon circles the earth every 28days . 月亮每28天繞地球一圈。
The plane circled the airport before landing . 飛機(jī)著陸前圍繞機(jī)場盤旋。
The news circled round very quickly . 這消息很快就傳開了。
6.It is possible to say not only what the weather is like at present , but also what is likely to happen in the next day or two .
因此，它不僅可以報(bào)告當(dāng)前的天氣情況，而且可以預(yù)報(bào)未來一兩天內(nèi)天氣可能會(huì)發(fā)生的情況。
a)It is possible to say…是一個(gè)由it作形式主語的句子，真正的主語是不定式to say…，隨后的兩個(gè)what-clause都是不定式to say的賓語從句，由not only…but also (不僅……而且……)連接。
b)What is likely to happen…中的likely為表語形容詞，意思是“很可能的”，后面常跟不定式短語，其結(jié)構(gòu)是：be likely to do sth。例如：
Tom is likely to win the game . 湯姆很可能會(huì)獲勝。
The volcano is likely to break out . 這座火山可能會(huì)爆發(fā)。
He is not likely to do it by himself . 他不大可能獨(dú)自做這件事。
c)句中的介詞短語at present意思是“現(xiàn)在”，“目前”，相當(dāng)于now一詞。例如：
I don’t need any help at present . 我目前還不需要任何幫助。
We’re getting along quite well at present . 我們目前相處得還不錯(cuò)。
需要注意的是present一詞，它既可作形容詞（在場的，出席的），又可作名詞（禮物）和動(dòng)詞（介紹，引見，贈(zèng)予），但作動(dòng)詞時(shí)的讀音則為 [pri’zent]。例如：
Were you present at the meeting yesterday ? 你出席昨天的會(huì)議了嗎？
Most of the people present were for the decision . 大多數(shù)在場 的人都贊成這一決定。（當(dāng)present一詞作定語時(shí)，放在被修飾的名詞之后，而不能放在其前面。）
I got a lot of presents on my birthday . 在我生日那天我收到了許多禮物。
The book was a present from my brother . 這本書是哥哥贈(zèng)送給我的。
They presented a sum of money to the school where they studied years ago .
他們向多年前曾經(jīng)就讀的學(xué)校贈(zèng)送了一筆款項(xiàng)。
Allow me to present my friend to you . 請(qǐng)?jiān)试S我把我的朋友介紹給你。
7.Ships and planes can be warned so that they can keep out of the path of the hurricane .
可以給船只和飛機(jī)發(fā)出警報(bào)，使它們能夠避開颶風(fēng)經(jīng)過的路線。
此句中的短語動(dòng)詞keep out of意為“不牽涉進(jìn)去”，“不要惹事”，“避開”（stay away from something bad）。例如：
Children are warned to keep out of the water . 警告孩子們離開水域。
Do keep out of the rain if you haven’t a raincoat . 沒帶雨衣那就避一下雨。
Mother asked Bill to keep out of trouble while she was away .
媽媽警告比爾在她外出時(shí)不要惹麻煩。
L.55
1.Today there are more than 100 nations in this group and dozens of satellites have been put into space .
今天這個(gè)集團(tuán)已擁有200多個(gè)成員國，數(shù)十枚衛(wèi)星已經(jīng)被送入太空。
句中的dozen為名詞，意為“一打”（相當(dāng)于a set of twelve），常用作單復(fù)同形，尤其在基數(shù)詞后。例如：
I bought two dozen pencils . 我買了兩打鉛筆。
I’d like to buy a dozen eggs . 我想買一打雞蛋。
注意：在這二個(gè)句子中，dozen不加s，后面也不用of。但如果dozen后面有these , those , them , us等詞時(shí)，dozen之后就要用of。例如：
Two dozen of them have passed the exam 他們中的二十四個(gè)人考試及格了。
另外，dozen表示不確切的多數(shù)時(shí)，其后加s，并用of，構(gòu)成了詞組dozens of…
這時(shí)表示的是一個(gè)較模糊的數(shù)的概念。例如：
Every morning several dozens of people gather in the park to do morning exercise .
每天清晨好幾十人聚集在公園進(jìn)行晨煉。
I’ve been to the Great Wall dozens of times . 我去過長城許多次了。
2.They can tell the difference between healthy plants and plants that are diseased .
它們（攝像機(jī)）還可以識(shí)別健康植物和患病植物之間的差異。
a)動(dòng)詞tell在本句中的意思是“區(qū)分”，“分清”。例如：
I can’t tell the difference between margarine and butter .
我嘗不出人造黃油和黃油有什么區(qū)別。
Can you tell Tom from his twin brother ?
你能分辨出湯姆和他的孿生兄弟嗎？
另外，“tell…from…”也是“說出”，“分清……和……的區(qū)別”的意思。例如：
Colour-blind people can’t tell red from green .
患有色盲的人分不清紅色和綠色。
The twins are so much alike that it’s impossible to tell one from the other .
這對(duì)雙胞胎非常相像，幾乎不可能把他們分辨出來。
b)在這個(gè)句子中，that are diseased是定語從句，修飾先行詞plants。而這個(gè)定語從句中的diseased是形容詞，在從句中作表語，其意為“有病的”，“病態(tài)的”。例如：
The tree in front of the house is diseased and it must be cut down .
房前的這棵樹有病，必須將其砍掉。
She is not only diseased in body but also in mind . 她身心都有毛病。
3.The problem with looking into space from the earth is that there is a lot of dust in the earth’s air .
從地球上觀察太空存在一個(gè)問題，這就是地球的大氣中有著大量的塵埃。
a)句中的介詞短語looking into space from the earth在句中作定語，修飾名詞problem，介詞with在句中的意思是“就……來說。”例如：
But with them the situation is quite different . 就他們來說，情況就大不一樣了。
The chief difficulty with these men was that they were old .
這些人的主要困難是年紀(jì)太大了。
b)look into這一短語動(dòng)詞是“觀察”，“窺視”的意思。例如：
He looked into the room , but saw nothing .
他們朝房間里看了看，但是什么也沒看見。
另外，look into還有“調(diào)查”，“了解”，“研究”的意思。例如：
We’ll look into the matter together . 我們將一起調(diào)查這件事。
Perhaps you wouldn’t mind looking into it for me ?
也許你不介意幫我了解一下這事吧？
He said he was looking into the possibility of buying a house .
他說他正在研究買房的可能性。
4.The dusty air makes it difficult to get a clear picture of space .
充滿塵埃的大氣給拍攝太空的清晰圖象造成了困難。
在這個(gè)句子中含有一個(gè)帶有it作為形式賓語的復(fù)合結(jié)構(gòu)，這就是make it difficult to get a clear picture，而真正的賓語則是動(dòng)詞不定式短語to get a clear picture .
英語中有些及物動(dòng)詞，其后要求跟復(fù)合賓語時(shí)，都可以跟一個(gè)帶形式賓語it的復(fù)合結(jié)構(gòu)；這些動(dòng)詞有find , suppose , think , make , consider等。而在這種復(fù)合結(jié)構(gòu)中，往往有一個(gè)形容詞或名詞作賓語補(bǔ)足語。例如：
I. consider it great honour to have been invited to such an important meeting .
我認(rèn)為被邀參加如此重要的會(huì)議是極大的榮幸。
He found it rather difficult to work the problem out without any help .
他覺得沒有任何幫助而解決這一難題是相當(dāng)困難的。
Children should make it a rule to wash hands before meals .
孩子們應(yīng)當(dāng)有一個(gè)規(guī)矩，就是用餐前要洗手。
He’s such a strange person that we all find it hard to get along with him .
他這人很怪，因此我們覺得很難與他相處。
II. Grammar語法
The attributive Clause定語從句
這里著重復(fù)習(xí)一下關(guān)于“介語+關(guān)系代詞”引導(dǎo)的定語從句。指人用關(guān)系代詞whom , 指物用關(guān)系代詞which。whom和which都是介詞的賓語。例如：
This is the room in which he lives .= This is the room where he lives .
第二句中的where是關(guān)系副詞，而第一句中的in which = where，介詞in在前時(shí)，關(guān)系代詞which不能省略，也不能用that代替。上面的句子也可以改寫成：
This is the room (which / that) he / lives in .
從這句子中可以看出介詞in在后時(shí)，關(guān)系代詞用which或that均可，且都可以省略。請(qǐng)看下面二組句子，1)中的句子是錯(cuò)誤的，而2)中的則是正確的。
1)The earth on where we live is a big ball .
The earth where we live on is a big ball . 我們所居住生活的地球是球狀的。
The earth on that we live is a big ball .
2)The earth on which we live is a big ball .
The earth which we live on is a big ball .
The earth that we live on is a big ball .
The earth we live on is a big ball .
The earth where we live is a big ball .
