　　二、重点与难点
　　l.53
　　1. i feel like going to a museum . 我想去参观博物馆。
　　此句中的短语动词feel like作＂想（做某事）＂、＂愿意＂、＂感到象是……样子＂解，它表示主观上的想法，后面跟名词或动名词形式。例如：
　　i’m hungry , i feel like eating something . 我饿了，我想吃点什么东西。
　　she didn’t feel like going to see a film that moment , for she had too much homework to do .
　　那时她不想去看电影，因为她有许多作业要做。
　　do you feel like coffee or soft drink ? 你想喝咖啡还是饮料？
　　表示＂想要做某事＂的意思时，本课中还出现了 ＂would like to do sth＂ ＂plan to do sth＂和would rather do sth .例如：
　　i’d like to visit the history museum . 我想参观历史博物馆。
　　what are you planning to do this sunday ? 你打算星期日做什么？
　　i’d rather stay at home . 我宁愿呆在家里。
　　2.so far as i know , it’s free . 据我所知，那个博物馆是不收门票的。
　　a)句中的so / as far as i know作插入语，与句子中的其它部分关系不密切，通常用逗号分开，其意思是＂就我所知＂。另外，so / as far as通常引出一个分句，意思为＂就……而言＂，＂尽……＂，＂至于……＂，＂到某种程度＂。例如：
　　so / as far as i know , we won’t be late , because we have plenty of time .
　　就我可知我们是不会晚的，因为我们有足够的时间。
　　as far as he is concerned , he can’t offord such an expensive car .
　　就他而言，他买不起如此昂贵的车。
　　he promised to help me as far as he could . 他答应要尽力地帮助我。
　　b)此句中的free意思是＂免费的＂，＂免税的＂。例如：
　　it’s free of charge and you don’t need to pay it .
　　这是免费的，因此你不必付钱。
　　does everyone in this country enjoy free medical care ?
　　这个国家的每个人都享受免费医疗吗？
　　3.personally , i’d rather go to the science museum .
　　就我个人来说，我倒想去科学博物馆。
　　此处的personally是副词，意思是＂就自己而言＂，＂就个人来说＂，相当于speaking for myself或as far as i am concerned . 例如：
　　personally , i agree with you . 就我个人来说，我还是赞同你的。
　　she said she disliked it , but personally i thought it was worth buying .
　　她说她不喜欢这个东西，但就我个人来说，我认为值得买下来。
　　除此之外，personally一词还有＂亲自地……＂之意。例如：
　　the headmaster personally showed the guests around the school .
　　校长亲自带领来宾们参观了学校。
　　4. they’ve got a special exhibition on this month .
　　他们这个月将举办一个特别的展览会。
　　在此句中，have got…on相当于have…on的意思，作＂有（某项活动）在进行＂解，这里的副词on有＂（某事）在发生或展示＂的意思。例如：
　　what’s on tonight ? 今晚有什么活动？
　　i’ve nothing on tonight ? 我今晚没什么活动。
　　i’m sorry i didn’t attend your party that night because i had a meeting on for that night .
　　对不起，那天晚上我没有参加你的聚会，因我有个会。
　　l.54
　　1. to escape the pull of the earth , a rocket must reach a speed of 28.4400 km / h .
　　为摆脱地球的引力，火箭的速度达到每小时四万公里。
　　a)句中的to escape the pull of the earth是动词不定式结构，在句中作目的状语，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 .
　　为了精通英语，你应该每天练习。
　　he worked day and night to finish his papers ahead of time .
　　为了提前完成论文，他日夜地工作。
　　b)这里要注意的是动词escape的用法，作为及物动词用时，后面跟名词或动名词；作为不及物动词用时，后面跟介词from，再加方位名词。例如：
　　it is reported that two of the prisoners have escaped . 据报道两个囚犯逃跑了。
　　a tiger escaped from the zoo . 一只老虎从动物园跑了出来。
　　how can we escape the crowds ? 我们如何避开人群？
　　those who break the law will not escape being punished .
　　触犯了法律的人是逃脱不了惩罚的。
　　c)pull一词在句中作名词用，意思是＂吸引力＂，同gravity。例如：
　　it’s not easy to break away from the pull of the earth .
　　要摆接吻地球的吸引力不是那么容易的。
　　作动词用时，它还用＂拉＂，＂托＂，＂拔＂的意思。
　　let’s go to the yard and pull up weeds . 咱们到院子里去拔草吧。
　　d)at a speed of表示＂以……单位速度＂，这时后面加速时的单位，speed一词前面加不定冠词。例如：
　　the car travels at a speed of 90 miles an hour .
　　小汽车以每小时80英里的速度行驶。
　　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离以外来欣赏这幅画，你就会觉得这是一幅漂亮的画。
　　the plane is flying at a height of 10,000 metres .
　　飞机正在10,000米的高空飞行。
　　2.first , it must be light , the lighter the better , because it has to be sent up into space by a rocket .
　　首先，它必须很轻，越轻越好，因为卫星得用火箭把它送入太空。
　　＂the lighter the better＂ 在句中是插入语，而且这是一个省略结构，全句应是这样的，
　　the lighter the satellite is , the better it will be .这种结构为：the + adj / adv .的比较级 + the + adj / adv .的比较级，表示＂越……，就越……＂的意思。例如：
　　the more you read , the more you know . 你读得越多，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 .它飞得越高，就显得越小。
　　3.it has equipment for making electricity from sunshine , using very broad sun panels .
　　它有太阳能发电设备，用的是很宽大的太阳能电池帆板。
　　a)句中的make…from…的意思是＂用……制成……＂。它常可以用于波动结构，例如：
　　i made a table from this kind of material . (the table was made from this kind of material .)
　　我用这种材料做了一张桌子。
　　my mother made me a shirt from the material i didn’t like .
　　我妈妈用我不喜欢的面料给我做了一件衬衣。
　　b)equipment一词是不可数名词。如以下各句中：
　　a new factory with modern equipment will be built here .
　　在这里将要建一个具有现代化设备的工厂。
　　radar equipment helps us a lot in our daily life .
　　雷达装置在日常生活中颇有用处。
　　c)using very broad sun panels结构是 ing短语形式，其作用是在句中用作方式状语，修饰making electricity from sunshine。例如：
　　we chinese eat our food , using chopsticks , while the westerners eat their food , using forks and knives .
　　我们中国人用筷子吃东西，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 .
　　一旦卫星进入地球转产，帆板就打下来吸收阳光。
　　a)once在句中是连词，引导一个时间状语从句，相当于as soon as…，在这种从句中，也不用将来时态，而只用一般时或完成时。例如：
　　once i decide to do something , i’ll try my best to do it well .
　　一旦我决定做什么事，我一定会尽力去把它做好。
　　once we have gathered enough proof , we can accuse him at the court .
　　我们一旦得到足够的证据，我们就可以在法庭上指控他。
　　a decision shouldn’t be changed once it is made .
　　一旦作出了决定，就不应当改变它。
　　另外，once还可以用作副词，作＂一次＂，＂曾经一度＂；＂过去＂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 . 这首歌曾经一度很流行。
　　b)动词unfold (展开)，它和fold (折叠)是一对反义词。例如：
　　she opened the letter , unfolded it and than read it .
　　她拆开信封，把信折开然后读了起来。
　　after reading the letter , she folded it and put it in the envelope again .
　　读完信之后，她把信叠好，又放入信封。
　　在英语中，有不少动词可以用加前缀un- , dis- 的方法，构成词义相反的词。如：
　　lock (上锁) unlock (开锁) like (喜欢) dislike (厌恶)
　　dress (穿衣服)undress (脱衣服) appear (出现)disappear (消失)
　　5.they remain above the same place on the earth and travel round it in a very high circle .
　　它们（卫星）保持在地面上周一位置的上方，在高空中环绕地球运行。
　　句中的circle一词是作为名词用的，它还可以用作动词。名词时其意为＂圆＂，＂圈＂，而作动词时，则作＂环绕＂，＂传播＂解。例如：
　　the children were standing in a circle , playing games .
　　孩子们站成一个圈，做游戏。
　　the teacher asked his students to use their compasses to draw circles .
　　老师要求学生们用圆规画圆。
　　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天绕地球一圈。
　　the plane circled the airport before landing . 飞机着陆前围绕机场盘旋。
　　the news circled round very quickly . 这消息很快就传开了。
　　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，它不仅可以报告当前的天气情况，而且可以预报未来一两天内天气可能会发生的情况。
　　a)it is possible to say…是一个由it作形式主语的句子，真正的主语是不定式to say…，随后的两个what-clause都是不定式to say的宾语从句，由not only…but also (不仅……而且……)连接。
　　b)what is likely to happen…中的likely为表语形容词，意思是＂很可能的＂，后面常跟不定式短语，其结构是：be likely to do sth。例如：
　　tom is likely to win the game . 汤姆很可能会获胜。
　　the volcano is likely to break out . 这座火山可能会爆发。
　　he is not likely to do it by himself . 他不大可能独自做这件事。
　　c)句中的介词短语at present意思是＂现在＂，＂目前＂，相当于now一词。例如：
　　i don’t need any help at present . 我目前还不需要任何帮助。
　　we’re getting along quite well at present . 我们目前相处得还不错。
　　需要注意的是present一词，它既可作形容词（在场的，出席的），又可作名词（礼物）和动词（介绍，引见，赠予），但作动词时的读音则为 [pri’zent]。例如：
　　were you present at the meeting yesterday ? 你出席昨天的会议了吗？
　　most of the people present were for the decision . 大多数在场 的人都赞成这一决定。（当present一词作定语时，放在被修饰的名词之后，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许多礼物。
　　the book was a present from my brother . 这本书是哥哥赠送给我的。
　　they presented a sum of money to the school where they studied years ago .
　　他们向多年前曾经就读的学校赠送了一笔款项。
　　allow me to present my friend to you . 请允许我把我的朋友介绍给你。
　　7.ships and planes can be warned so that they can keep out of the path of the hurricane .
　　可以给船只和飞机发出警报，使它们能够避开飓风经过的路线。
　　此句中的短语动词keep out of意为＂不牵涉进去＂，＂不要惹事＂，＂避开＂（stay away from something bad）。例如：
　　children are warned to keep out of the water . 警告孩子们离开水域。
　　do keep out of the rain if you haven’t a raincoat . 没带雨衣那就避一下雨。
　　mother asked bill to keep out of trouble while she was away .
　　妈妈警告比尔在她外出时不要惹麻烦。
　　l.55
　　1.today there are more than 100 nations in this group and dozens of satellites have been put into space .
　　今天这个集团已拥有200多个成员国，数十枚卫星已经被送入太空。
　　句中的dozen为名词，意为＂一打＂（相当于a set of twelve），常用作单复同形，尤其在基数词后。例如：
　　i bought two dozen pencils . 我买了两打铅笔。
　　i’d like to buy a dozen eggs . 我想买一打鸡蛋。
　　注意：在这二个句子中，dozen不加s，后面也不用of。但如果dozen后面有these , those , them , us等词时，dozen之后就要用of。例如：
　　two dozen of them have passed the exam 他们中的二十四个人考试及格了。
　　另外，dozen表示不确切的多数时，其后加s，并用of，构成了词组dozens of…
　　这时表示的是一个较模糊的数的概念。例如：
　　every morning several dozens of people gather in the park to do morning exercise .
　　每天清晨好几十人聚集在公园进行晨炼。
　　i’ve been to the great wall dozens of times . 我去过长城许多次了。
　　2.they can tell the difference between healthy plants and plants that are diseased .
　　它们（摄像机）还可以识别健康植物和患病植物之间的差异。
　　a)动词tell在本句中的意思是＂区分＂，＂分清＂。例如：
　　i can’t tell the difference between margarine and butter .
　　我尝不出人造黄油和黄油有什么区别。
　　can you tell tom from his twin brother ?
　　你能分辨出汤姆和他的孪生兄弟吗？
　　另外，＂tell…from…＂也是＂说出＂，＂分清……和……的区别＂的意思。例如：
　　colour-blind people can’t tell red from green .
　　患有色盲的人分不清红色和绿色。
　　the twins are so much alike that it’s impossible to tell one from the other .
　　这对双胞胎非常相像，几乎不可能把他们分辨出来。
　　b)在这个句子中，that are diseased是定语从句，修饰先行词plants。而这个定语从句中的diseased是形容词，在从句中作表语，其意为＂有病的＂，＂病态的＂。例如：
　　the tree in front of the house is diseased and it must be cut down .
　　房前的这棵树有病，必须将其砍掉。
　　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 .
　　从地球上观察太空存在一个问题，这就是地球的大气中有着大量的尘埃。
　　a)句中的介词短语looking into space from the earth在句中作定语，修饰名词problem，介词with在句中的意思是＂就……来说。＂例如：
　　but with them the situation is quite different . 就他们来说，情况就大不一样了。
　　the chief difficulty with these men was that they were old .
　　这些人的主要困难是年纪太大了。
　　b)look into这一短语动词是＂观察＂，＂窥视＂的意思。例如：
　　he looked into the room , but saw nothing .
　　他们朝房间里看了看，但是什么也没看见。
　　另外，look into还有＂调查＂，＂了解＂，＂研究＂的意思。例如：
　　we’ll look into the matter together . 我们将一起调查这件事。
　　perhaps you wouldn’t mind looking into it for me ?
　　也许你不介意帮我了解一下这事吧？
　　he said he was looking into the possibility of buying a house .
　　他说他正在研究买房的可能性。
　　4.the dusty air makes it difficult to get a clear picture of space .
　　充满尘埃的大气给拍摄太空的清晰图象造成了困难。
　　在这个句子中含有一个带有it作为形式宾语的复合结构，这就是make it difficult to get a clear picture，而真正的宾语则是动词不定式短语to get a clear picture .
　　英语中有些及物动词，其后要求跟复合宾语时，都可以跟一个带形式宾语it的复合结构；这些动词有find , suppose , think , make , consider等。而在这种复合结构中，往往有一个形容词或名词作宾语补足语。例如：
　　i. consider it great honour to have been invited to such an important meeting .
　　我认为被邀参加如此重要的会议是极大的荣幸。
　　he found it rather difficult to work the problem out without any help .
　　他觉得没有任何帮助而解决这一难题是相当困难的。
　　children should make it a rule to wash hands before meals .
　　孩子们应当有一个规矩，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 .
　　他这人很怪，因此我们觉得很难与他相处。
　　ii. grammar语法
　　the attributive clause定语从句
　　这里着重复习一下关于＂介语+关系代词＂引导的定语从句。指人用关系代词whom , 指物用关系代词which。whom和which都是介词的宾语。例如：
　　this is the room in which he lives .= this is the room where he lives .
　　第二句中的where是关系副词，而第一句中的in which = where，介词in在前时，关系代词which不能省略，也不能用that代替。上面的句子也可以改写成：
　　this is the room (which / that) he / lives in .
　　从这句子中可以看出介词in在后时，关系代词用which或that均可，且都可以省略。请看下面二组句子，1)中的句子是错误的，而2)中的则是正确的。
　　1)the earth on where we live is a big ball .
　　the earth where we live on is a big ball . 我们所居住生活的地球是球状的。
　　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 .
