精讲典析
1. Science is developing so fast that it is beyond our imagination.（page 41）
科学的发展如此之快，超出我们的想像。
(1) beyond是介词，常见用法为：
①（表示时间）迟于；过了……以后
Don’t stay there beyond midnight. 不要过了午夜还留在那儿。
② 超出（某种数量、限度）；超出……的范围；非……可及
The switch on the wall was beyond the baby’s reach. 装在墙上的开关婴儿是摸不到的。
We saw a building some distance beyond the woods.
我们看见在树林之外不远的地方有一个建筑物。
It’s beyond human power. 它超出了人的力量。

如果汤姆干不了这项工作，我也干不了。
③ 除……之外（常用于含疑问或否定意义的结构中）

除了他那颇为古怪的口音以外，我没有注意到别的。
④ beyond作副词时表示“再往前”或“再过去”。例如：
There is nothing beyond. 再过去就什么也没有了。
The hill blocks our view. What’s beyond? 小山挡住了我们的视线。再往前是什么呢？
(2) imagination n. “想像力、空想、幻想物”，多用作不可数名词。例如：
The story shows plenty of imagination. 这个故事表现出丰富的想像力。

It does not take great imagination to guess what happened next. 随后发生的事情不难想象。
2. A recent announcement by scientists that they have successfully cloned the first human embryo has caused much debate and has shocked many people around the world.（page 42, lines 1—3）科学家最近宣布，他们已克隆出第一个人类胚胎，这在全球范围内引起了沸沸扬扬的辩论，许多人为之感到震惊。
(1) 句中that引导同位语从句，对抽象名词announcement做具体说明。announcement 与引导词that之间被by scientists隔开。例如：
They made a public announcement that the wages of the workers would be increased.
他们发布了通告，那些工人的工资将会提高。
His sudden announcement that she was leaving took us quite by surprise.
他突然说要离去, 这使我们非常惊奇。
(2) announcement n. “通告、公告”，可数名词。例如：

3. On the one hand, some scientists point out that if you clone an embryo, you can produce valuable tissues and organs that could be used to save human life.（page 42, lines 3—5）一方面，一些科学家指出，如果你能够克隆出人类胚胎，就可以制造出拯救人类生命的宝贵的组织和器官了。
(1) on the one hand意为“一方面”，on the other hand意为“另一方面”。两个短语都是表连接作用的副词性短语。可以同时用在一个句子中。例如：
On (the) one hand, I want to go to the party, but on the other hand I ought to be studying at home. 一方面我想去参加宴会，而另一方面我应当在家学习。
On the one hand this job doesn't pay very much, but on the other hand I can’t get another one.
一方面这份工作报酬不高，可另一方面我又找不到其他工作。
(2) 辨析：point out, point to, point at
注意这一组短语的区别。
① point out“指出、使注意”的意思。例如：
This guide book points out the main facts of early American history.
这本导游手册讲述了美洲早期的重要史实
Can you point out the church in the picture? 你能指出图片里的教堂吗？

The hands of the clock pointed to half past eight. It was time we put our children to bed.
钟的指针指在八点半上, 我们该让孩子们上床睡觉了。

The guide pointed at a tower and told us that it was built hundreds of years ago.
导游指着一座塔, 告诉我们说这是数百年前修建的。
It’s rude to point your fingers at people. 用手指指人是很失礼的。
4. On the other hand, many people, including some scientists disagree and fear that if mankind interferes with nature in this way, they may be on their way to producing a real-life Frankenstein’s monster.（page 42, lines 5—7）
另一方面，很多人，包括一些科学家都反对并担心如果人类以这种方式干涉自然的话，他们将制造出现实生活中的弗兰肯斯坦怪物。

I am not going to be interfered with. 我不想别人干预我的事情。
He was afraid this would interfere with his study. 他担心这会妨碍他的学习。
I don’t want to interfere with you; proceed with your work.
我不想打扰你了, 你继续工作吧。
Who interfered with my camera? 谁擅自用过我的照相机?
(2) on one’s (the) way to/towards (doing) sth “即将做……”, 如果to后接一表地点的名词，应理解为 “在去......的路上”。例如:
We’re on the way towards an election victory. 我们即将赢得大选。
He’s well on the way to establishing himself among the top ten players in the world.
他即将进入世界前十名顶尖选手的行列。

5. However, in general the scientists were praised for their wonderful scientific breakthrough.（page 42, lines 12—13）但整体而言，科学家因为杰出的科学突破而受到赞扬。
辨析：in general, as a whole
这两个短语意义比较接近，都有“总的说来；大体上；通常”的意思，在句子中位置也比较灵活，仔细斟酌还是有着微细的区别。
① in general强调“个体或局部”。例如：
Women in general like to shop for new clothes. 大多数妇女喜欢逛街买新衣服。

② 做名词用“称赞、赞美、赞扬、表扬”。例如：

The audience was full of praise for the whole production. 观众对整部作品称赞不已。
③ in praise of短语常见在句中做状语。例如：

6. However, some people consider that cloning human embryos with the intention of destroying them shows no respect for human life.（page 42, lines 18—20）但也有人认为，怀着摧毁它们的意图来克隆人类胚胎，是对人类生命的不尊重。
(1) with the intention of “抱有……目的、打算”，是一短语介词，在句中做状语表目的。例如：

(2) 辨析：intention, goal, aim, purpose
这些名词都指人想要达到的 “目的”，但各有侧重。

③ goal 可指理想的或甚至遥远的目标。例如：

我们的目标是赚足够的钱使公司支撑下去。

④ aim 强调为追寻某种目的而努力奋斗的方向。例如：
His only aim in life is to enjoy himself. 他人生唯一的目的就是享受生活。

7. While cloning human embryos is illegal in many countries, some scientists are already pushing ahead with research so as to deliver a cloned human baby.（page 42, lines 27—28）尽管克隆人类胚胎在很多国家属于非法，有些科学家已加紧研究，以便降生一个克隆的人类婴儿。
(1) push ahead with短语在句中做“推进、推行”理解。例如：

无论发生什么情况, 我们都必须推行我们的增产计划。
He promised to push ahead with economic reform. 他允诺继续推行经济改革。
We are pushing forward with our plan. 我们正坚决实施计划。
(2) 辨析：push ahead，go ahead
两个短语都有“前进”的意义，ahead是副词，都是不及物词组，但其区别也是明显的。
① push ahead强调“向前推进、急速前进”
If we push ahead, we can get home before dark. 如果我们抓紧, 天黑前我们还能赶到家。
I want to push ahead on this project. 有关这个方案我想继续取得进展。

(1) 辨析：unique, only
两个词做形容词用都有“唯一的”的意思，但意义上区别较大。

(2) 辨析：for sale, on sale

She has put her house up for sale. 她现在的房子在出售。(状语)

9. The human race is using up Earth’s resources. （page 43, line 41）人类正耗尽地球上的资源。
(1) use up “用光、耗尽”，use仅指动作过程，而use up则强调结果；英语中不少动词都是如此。例如：

他知道怎样使用这笔存款，用不了多久这笔钱会全部用完。
She didn’t want to end the relationship. But she finally had to end it up.

她得把花园挖一挖, 结果在花园里挖出了一枚古硬币。
(2) 辨析：use up, run out, run out of
表示“用完”时，这些词组意义相同，但用法不同。
① use up是及物动词短语，其主语是人。例如：
I’ ve used up all the glue. = All the glue has been used by me. 我把胶水都用光啦。
② run out是不及物动词词组，表示“被用完了（become used up)”，含被动意义，其主
语通常是时间、金钱、食物等无生命名词。例如：
His money soon ran out. 他的钱很快就花完了。
Food supplies had run out towards the end of the trip. 在旅行快结束时，食物已经吃完了。
③ run out of 含有介词of，作及物动词用，“用完(=use up)”的意思。例如：

What if I've run out of money？我把钱花光了怎么办？
10. I am in complete agreement with human cloning.（page 43, lines 49—50）我完全同意克隆人类。
(1) in agreement with 是一短语介词，句中be in complete agreement with/about 是系表结构= quite agree with /about，意思是“完全同意；意见一致”，其介词短语还可以在句中做其他成分。例如：

I am quite in agreement with what you say. 我十分同意你说的话。

我发现自己的意见几乎完全与托尼一致。

11. Seven years ago, my 10-year-old daughter died of heart failure.（page 43, lines 52—53）七年前，我10岁的女儿死于心脏病。

In a cold winter, many wild animals may die of hunger.

12. Question things you do not understand or that do not appear to make sense. (page 43) 对于你不了解的地方，或者似乎讲不通的地方，要提出问题。
辨析：appear, seem
两个词做系动词用都有“似乎、好像”的意思，含义似乎没有多大差异，在句型结构上也基本一样，有时候也能互换，微细的区别仍然值得注意。
① appear暗含“的确如此”含义，如果要表示某种判断而得出的印象最好用appear。appear还可以是行为动词“出现，显现”的意思。例如：
It appeared that he had a taste for music. = He appeared to have a taste for music.
看来他对音乐还有一定的鉴赏力。
They appear / seem to have misunderstood me. = It appears /seems that they have misunderstood me. 他们似乎误解了我。

那个女演员三十五岁了，但是她看上去年轻得多。
② seem所表示的“似乎”或“看来”是以客观的迹象为依据。还可以有It seems as if…句型，而appear则不能用于此句型。例如：

The baby seems (to be) asleep. = It seems that the baby is asleep. 那婴孩好像是睡着了。

13. Why do some people think they have the right to go against nature?（page 45）为什么有些人认为他们有权与自然对抗呢？
辨析：go against, be against
他们基本同义，都有“反对、违背、不利于”的意思，仍有区别。
① go against sb. /sth 指“动作”。例如：
Don’t go against your parents /your parents’ wishes. 不要违背父母亲的愿望。
He went against the advice of his colleagues and resigned. 他不顾同事们的劝告辞了职。
② be against指“状态”。例如：

14. I believe that strict laws should be put in place and governments should do more to stop human cloning.（page 45）我认为应该严格立法，政府也该采取更多的措施阻止人类克隆。
in place 在句中作状语，意思是“在对的位置”、“在适当的位置”，其反义短语out of place“不合适; 不恰当”。在句中做表语有“合适的；恰当的”的意思。例如：

Some of these books are out of place. Please put them in right order.
有些书位置不对, 请把它们按顺序放好。

精讲典析
1. This is the organ that controls the rest of the organs, just like the headmaster controls the school.（page 47）正是这个器官控制其他器官，正如校长控制学校一样。
辨析：the rest, the other
两者都有“其他的、其余的”的意义，但他们的区别较大。
① rest是名词，即可指人也可指物，多指某一整体范围之内的其他；the rest (of +名词) 做主语时，谓语动词可以用单数形式，也可以用复数形式，应视the rest所代替的那个名词而定。例如：
I have got two bright students in the class, but the rest (of the students) are average.
这个班我有两个聪明的学生，其余的平常。
I’ll keep one third of the money and the rest (of the money) is for you.
我留下三分之一的钱，其余的给你。
The beginning of the lecture was boring, but the rest was interesting.
开始部分演讲十分枯燥，但是其余部分很有趣。
The rest of the bicycles are on sale today. 其余的自行车今日上市销售。
② other是代词，单数是两者中的“另一”，复数才指“其余的(人或物)”；多指若干个个体中的其余部分。做形容词用时亦是如此。例如：
She gave me one book last week and promised to bring the other on Wednesday.
她上周给了我一本书，并承诺星期三带来另一本。
I went swimming while the others played basketball. 我去游泳, 其余的人都去打篮球了。

2. He is always working in his lab, trying to figure out all the mysteries that make him puzzled.（page 49）他总是在实验室工作，尽力去弄明白所有使他困惑的奥秘。
figure out在句中意为“弄明白”; figure out还可表示“计算出”或“解决”。例如：
I just can’t figure him out. 我简直摸不透他。
No one can figure out how the fire started. 没有人弄得清这场火灾是怎么引发的。
Could you help me figure out this problem? 你能帮我解决这问题吗?
I have figured out how much during the week I spent. 我算出了这个星期花了多少钱。
3. He must have been working too hard to notice!（page 49）他可能太专注于工作了，根本没有注意到。
must have been working是情态动词must 接动词的现在完成进行时，表示对过去事情的推测，意思是“肯定一直在……”，“想必一直在……”。例如：
John must have been playing football and Mary must have been doing her homework.约翰肯定一直在踢足球，而玛丽想必一直在做作业。
You must have been overdoing things a bit. 想必你一直以来都过于劳累。
3. I think we should be cautious and use good judgment when making decisions about cloning.（page 49）我认为在就克隆问题作出决策时，应当慎重行事，作出理智判断。
辨析：cautious, careful

If I had been more cautious, I might have done better. 我要是再谨慎一点，可能做得更好。
We should be cautious of strangers. 我们应该提防陌生人
The bank is very cautious about lending money. 银行在贷款方面十分慎重。
② careful侧重做事谨慎、留心，特别注意一些细节地方，着眼于“行动”。例如：

Be careful not to lose her address. 小心别把她的地址给弄丢了。
4. Although it involves some cost on your part, you will definitely agree it’s worth it! （page 49）尽管要支付一笔费用，但你肯定会认为是值得的。
(1) involve vt. "使卷入、牵涉、包括”，常用句型：involve sb. in 使参与〔陷入, 牵扯到〕

The project involved great expense. 那项工程开支巨大。

There was a series of errors on my part. 我犯了一连串的错误。
5. Treated with electricity, the cell tissue will split into several parts.（page 50）采用电疗，这个细胞的组织会分裂成几个部分。
split into, divide into, separate into
这一组短语都有“分成 /为……”的意义，在句型结构上也非常接近, 归纳如下：
① 主语是sth.动词与介词into不拆分。例如：
The river splits into three smaller streams at this point. 这条河在此处分成三条小河
The class separated into several smaller groups to talk about the subject.
这个班的学生分成了几个小组讨论这个问题。

词根加上前缀或后缀而构成的新词叫派生词。通常前缀改变词义，后缀改变词性。如unbelievable一词，其构成为：un—believe—able，前缀un- 表否定，形容词后缀 -able表示“能够的”，由此可推断unbelievable的意思为“not able to believe”(难以置信的)。因此，掌握一些有关前缀的和后缀的知识对学习英语词汇有很大的帮助。

语法知识
过去分词
过去分词作非谓语动词用时，它具有形容词和副词的语法特征，在句子中做定语、表语、宾语补足语和状语。过去分词常表示被动意义；在时间关系上，过去分词通常表示动作已完成；不及物动词的过去分词，不表示被动意义，只表示完成意义。
1. 用法
定语 The injured boy was sent to hospital.
He carefully studied the stamps collected in London.
表语 The glass is broken.
宾语补足语 You must get your hair cut.
状语 The old man stood up, supported by his son.
He came into his office, followed by two guards.
Seen from the top of the hill, the city is more beautiful.
① 作定语。单个过去分词或复合词一般放在所修饰的名词前；过去分词短语作定语时，则放在所修饰的词后面，被修饰的词和过去分词应是被动的逻辑主谓关系即主动意义上的动宾关系或逻辑上的系表结构表状态，都可以转换成一个含有被动语态或系表结构的定语从句。例如：
man-made satellites（人造卫星），school-run factories（校办工厂）
Students always grow with newly found knowledge. (page 47)
学生总是用新发现的知识伴随着自己成长。
A surprised look appeared on his face when he heard that his friend had died．
当他听说他的朋友死了，他脸上显示出吃惊的表情。
A letter(that is) posted today will reach him the day after tomorrow．
今天发出的信后天他能收到。（post与a letter存在意义上的动宾关系。）
I want a child (that is) genetically related to me. (page 42, lines 24-25)
我想一个在基因上有关系的孩子。
② 作表语。表示主语所处的状态; 除了系动词be外，还有其他的系动词也常见用过去分词做表语。常用作表语的过去分词有interested，excited，disappointed，delighted，discouraged， drunk，amused，astonished，tired，surprised， pleased，satisfied，worried，upset，married，frightened等。例如：
That’s disappointed. I think you’ll be pleased when it’s finished. (page 51)
真让人失望。我想作业做完的时候，你会开心的。
He sounded so thrilled. (page 49) 他听起来如此激动。
Otherwise you will get bored. (page 49) 否则你会觉得无聊。
I’m totally burnt out. (page 51) 我完全筋疲力尽了。
③ 作宾补。和宾语一起构成复合宾语，宾语是其逻辑主语。 have, make, get, keep, hear, feel, see, find, watch, notice, imagine, consider, want, wish, desire, like等动词常接过去分词作宾补。
He is always working in his lab, trying to figure out all the mysteries that make him puzzled.（page 49）他总是在实验室工作，尽力去弄明白所有使他困惑的奥秘。
He spoke loudly in order to make himself heard.
I’m gong to have my house repaired next week.
He had to get the form signed by a doctor.
He heard his name called.
I found the city greatly changed.
④ 作状语。常修饰谓语动词所表示的动作，可表示时间、原因、方式、伴随等，其逻辑主语是句子的主语，主语和过去分词同样构成逻辑主谓的被动关系，可以同相应的状语从句进行转换。例如：
Treated with electricity, the cell tissue will split into several parts.（page 50）= When it is treated with electricity, the cell tissue will split into several parts.
采用电疗，这个细胞的组织会分裂成几个部分。(表时间)
Given more time, I’ll work out all the maths problems．=If I am given more time, I’ll work out all the maths problems．(表条件)
Driven by a greater demand of vegetables, farmers have built more green houses. =As they are driven by a greater demand of vegetables, farmers have built more green houses. (表条件)
⑤ with+名词(或代词)+过去分词
在介词with的复合结构中，过去分词和前面的名词或代词构成逻辑主谓的被动关系, with复合结构在句中做状语。例如:
I sat in my room for a few minutes with my eyes fixed on the ceiling.
我在房间坐了一会儿，眼睛盯着天花板。（表伴随）
She had to walk home with her bike stolen. 自行车被偷，她只好步行回家。（表原因）
I had the TV on with the sound turned down. 我让电视机开着，但音量调低了。（表方式）
2. 分词的独立结构
当过去分词做状语表时间、条件、让步或方式时，可以在分词前加上相应的连词when /while / before /after /since /if /unless /though等；在状语从句中，当主从句的主语一致且谓语中含有系动词或助动词be时，从句的主语和be就可省略。例如：
Unless invited to speak, he remained silent.
When offered help, one often says “Thank you.” or “It’s kind of you.”
When completed, the museum will be open to the public next year.
When asked why he went there, he said he was sent there to be trained for a space flight.
3. 过去分词与现在分词完成被动式的用法比较
现在分词的完成被动式作状语，有时可与过去分词换用。过去分词侧重于动作的被动，现在分词完成被动式侧重于动作的完成(即强调与谓语动作的先后关系)。如果不强调动作的先后，只强调动作的被动，这时只用过去分词，不用现在分词完成被动式。例如：
Having been discussed (Discussed) many times, the problems were settled at last.
Having been shown around the Water Cube, we were then taken to see the Bird’s Nest for the 2008 Olympic Games.
4. 作状语时表示主动意义的过去分词
有些过去分词因为来源于系表结构，其本身已经是形容词了，作状语时不表被动而表主动意义。常见的这类词有：lost（迷路的、迷失的），seated（就座的），hidden（隐秘的、隐藏的），absorbed in（投入的、全神贯注的），born（出生的、产生的），dressed in（穿戴好的），tired of（厌倦的、厌烦的）等。例如：
Absorbed in deep thought, he didn’t hear the sound.
Born in this beautiful town, he hates to leave it.
Faced with so much trouble, we failed to complete the task on time.
Interested in the subject, he spent much time reading the books.

9. Would anyone say that economic development should be stopped in favour of nature? （page 58, lines 9—10）会有人说为了照顾自然就该停止经济发展吗？

turn out常用于两种句型结构。
① It turns out that … “结果是……” ; 如果that从句中是一般过去时，可以表示“没想到是……”，“原来却是……”。例如：
It turns out that the method doesn’t work well. 结果是这个方法不管用。

11. It is mankind’s responsibilities to find solutions that are acceptable for everyone, and everything. (page 58, lines 32-33) 找出对任何人、任何事物都可以接受的方案，是人类的责任。
① 这是一强调句，强调部分是句子的主语mankind’s responsibilities to find solutions

课题实践
How to write a formal letter
1. 正式信函的写作原则
由于电子邮件的普及，书信写得越来越少，但一旦我们要写，那一定是很重要的信件，比如说求职信、投诉信等。因此，我们要让书信给读者留下深刻印象，起到预期的作用。写书信时我们要遵循下列原则：
in the correct format 格式正确
short and to the point 简短，切中要害
relevant 具有相关性
free of any grammatical or spelling mistakes 没有语法和拼写错误
polite, even if you’re complaining 有礼貌，哪怕是投诉信
well presented陈述恰当
2. 正式信函的写作格式要求
正式信函要求格式规范，要包含信件构成的各个要素：
写信人地址：在信的右上角
收信人地址：在信的左上角，接着写信人地址下面写。
日期：可在左边，也可在右边，月份不用缩写
称呼：用“Dear+姓”，不知道姓名时用Dear Sir或Dear Madam。不知道是Mrs 还是Miss时，可以使用Ms。
结尾：使用Yours Faithfully，Yours Sincerely结尾。
签名：在左下方，与正方开头对齐。商务信件中，须在签名后列出自己所属的公司，自己的职位及公司地址，电话簿。
3. 信的内容
第一段简要说明写信的目的，是问询、投诉还是请求等。
第二部分可以是一段，也可以是几小段，是书信的主体内容。英文信不宜过长，因此要
简明扼要说明事情。要清晰、紧凑，逻辑性强。
最后一段正式书信中往往写明你希望收信者采取什么行动。常用结束语有：
Awaiting your good news.
Looking forward to your early reply.
Hoping to hear from you soon.
We await your good news.
I hope to hear from you very soon.
We look forward to your reply at your earliest convenience. 静候佳音
I look forward to our next meeting in Los Angeles. 期待我们下次在咯杉矶的会面。
Your early reply will go highly appreciated. 急盼佳音。
We shall be pleased to send you what you wanted, 如果你需要些什么，我们会非常乐意给
你寄过去 。
The help you give me is sincerely valued. 你给我的帮助非常宝贵。
I hope everything will go well with you. 我祝你万事如意。
Please let us know if you want more information. 如果需要更多的信息，请尽管通知我。
I hope you always enjoy yourself. 我希望你永远开心。
I wish you every success in the coming year. 我祝你来年一切如愿。
Please remember me to your family. 请代我向你的家人问好。
All the best. 祝你万事如意。
With love and good wishes. 给你最好的祝愿。
现在，假如你叫Louise Longford，是个健美教练，想要去一家叫做Fitness First的公司应聘，请给Mr G. Sands写一封求职信。
首先确定信的格式；然后在第一段说明写信的目的是应聘健美教练；中间段落列出自己的优点，说明自己能胜任这份工作；最后一段写出自己的希望。
Louise Longford的求职信：
12, Kenmore Road
Littletown
LT12 9BH
1st December 2009
Mr G. Sands
Fitness First
Lake Road
Littletown
LT1 5MX
Dear Mr Sands
Re: Fitness Instructor FF/32
I am writing to apply for the job of Fitness Instructor, as advertised in Thursday's Courant. This is an ideal job for me given my enthusiasm for sport, my related experience and qualifications.
Sport and fitness training have always been important to me, which is why I chose to take a BTEC Diploma in Sports Science. I obtained distinctions in the Sports Anatomy & Physiology and Sports Injuries modules last year and am confident that I will get similar marks in Exercise Physiology, Mechanics of Sport and Sports Supervision & Management this year. I am a confident user of Microsoft Office xp and have worked extensively with Fitness Publisher, a program for analysing fitness.
As you can see from my CV, I've taken the opportunity to gain extra qualifications that were on offer at college, which has helped me get part-time work as a pool attendant. I'm called on to provide cover during busy times so am used to working irregular hours at short notice. I've also run a lunchtime aerobics class at college since the start of this year.
I finish college in six weeks and am keen to find a job rather than carry on with further full-time study. I could start any part time work or training sooner as many of my classes are finishing and most of my assignments are done. I look forward to hearing from you.
Yours sincerely，
Louise Longford
书信写完后，要根据上述原则进行检查，以保证书信质量。相信看过你写的求职信，Mr Sands会很乐意招聘你。
