精講典析
1. Science is developing so fast that it is beyond our imagination.（page 41）
科學的發展如此之快，超出我們的想像。
(1) beyond是介詞，常見用法為：
①（表示時間）遲于；過了……以后
Don’t stay there beyond midnight. 不要過了午夜還留在那兒。
② 超出（某種數量、限度）；超出……的范圍；非……可及
The switch on the wall was beyond the baby’s reach. 裝在墻上的開關嬰兒是摸不到的。
We saw a building some distance beyond the woods.
我們看見在樹林之外不遠的地方有一個建筑物。
It’s beyond human power. 它超出了人的力量。

③ 除……之外（常用于含疑問或否定意義的結構中）

除了他那頗為古怪的口音以外，我沒有注意到別的。
④ beyond作副詞時表示“再往前”或“再過去”。例如：
There is nothing beyond. 再過去就什么也沒有了。
The hill blocks our view. What’s beyond? 小山擋住了我們的視線。再往前是什么呢？
(2) imagination n. “想像力、空想、幻想物”，多用作不可數名詞。例如：
The story shows plenty of imagination. 這個故事表現出豐富的想像力。
Poets and artists have imagination. 詩人和藝術家都有想象力。
It does not take great imagination to guess what happened next. 隨后發生的事情不難想象。
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）科學家最近宣布，他們已克隆出第一個人類胚胎，這在全球范圍內引起了沸沸揚揚的辯論，許多人為之感到震驚。
(1) 句中that引導同位語從句，對抽象名詞announcement做具體說明。announcement 與引導詞that之間被by scientists隔開。例如：
They made a public announcement that the wages of the workers would be increased.
他們發布了通告，那些工人的工資將會提高。
His sudden announcement that she was leaving took us quite by surprise.
他突然說要離去, 這使我們非常驚奇。
(2) announcement n. “通告、公告”，可數名詞。例如：
There are several announcements in the newspaper today.
今天的這張報紙上有好幾個通告。
The company put up an announcement on the wall. 那家公司在墻壁上貼了一個通告。
The announcement about their marriage has appeared in the newspaper.
他們結婚的通告已經刊登在報紙上了。
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，一些科學家指出，如果你能夠克隆出人類胚胎，就可以制造出拯救人類生命的寶貴的組織和器官了。
(1) on the one hand意為“一方面”，on the other hand意為“另一方面”。兩個短語都是表連接作用的副詞性短語。可以同時用在一個句子中。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. 一方面我想去參加宴會，而另一方面我應當在家學習。
On the one hand this job doesn't pay very much, but on the other hand I can’t get another one.
一方面這份工作報酬不高，可另一方面我又找不到其他工作。
(2) 辨析：point out, point to, point at
注意這一組短語的區別。
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.
這本導游手冊講述了美洲早期的重要史實
Can you point out the church in the picture? 你能指出圖片里的教堂嗎？
He pointed out that the road was not safe that day. 他指出，那條道路那天不安全。
② point to “顯示……的位置/方向”。例如：

The hands of the clock pointed to half past eight. It was time we put our children to bed.
鐘的指針指在八點半上, 我們該讓孩子們上床睡覺了。

導游指著一座塔, 告訴我們說這是數百年前修建的。
It’s rude to point your fingers at people. 用手指指人是很失禮的。
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，包括一些科學家都反對并擔心如果人類以這種方式干涉自然的話，他們將制造出現實生活中的弗蘭肯斯坦怪物。
(1) interfere with sb./sth. “干涉、干預；擺弄、妨礙”。例如：
I am not going to be interfered with. 我不想別人干預我的事情。
He was afraid this would interfere with his study. 他擔心這會妨礙他的學習。
I don’t want to interfere with you; proceed with your work.
我不想打擾你了, 你繼續工作吧。
Who interfered with my camera? 誰擅自用過我的照相機?
(2) on one’s (the) way to/towards (doing) sth “即將做……”, 如果to后接一表地點的名詞，應理解為 “在去......的路上”。例如:
We’re on the way towards an election victory. 我們即將贏得大選。
He’s well on the way to establishing himself among the top ten players in the world.
他即將進入世界前十名頂尖選手的行列。

5. However, in general the scientists were praised for their wonderful scientific breakthrough.（page 42, lines 12-13）但整體而言，科學家因為杰出的科學突破而受到贊揚。
辨析：in general, as a whole
這兩個短語意義比較接近，都有“總的說來；大體上；通常”的意思，在句子中位置也比較靈活，仔細斟酌還是有著微細的區別。
① in general強調“個體或局部”。例如：
Women in general like to shop for new clothes. 大多數婦女喜歡逛街買新衣服。
The class are, in general, very bright. 總的說來, 這個班級的學生都很聰明。

② 做名詞用“稱贊、贊美、贊揚、表揚”。例如：

③ in praise of短語常見在句中做狀語。例如：
He gave a speech in praise of the school. 他在講話中稱贊了這所學校。
The teacher spoke in praise of the child for his honesty. 他很誠實, 老師表揚了他。
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）但也有人認為，懷著摧毀它們的意圖來克隆人類胚胎，是對人類生命的不尊重。
(1) with the intention of “抱有……目的、打算”，是一短語介詞，在句中做狀語表目的。例如：

(2) 辨析：intention, goal, aim, purpose
這些名詞都指人想要達到的 “目的”，但各有側重。
① intention 只指某人想要追隨的行動方向。例如：
Do you have any intention of applying for the job? 你打算申請這個工作嗎？
It is not my intention to argue with you. 我不是想和你爭論。
If I've hurt your feelings, it was quite without intention.

我們的目標是賺足夠的錢使公司支撐下去。

④ aim 強調為追尋某種目的而努力奮斗的方向。例如：

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）盡管克隆人類胚胎在很多國家屬于非法，有些科學家已加緊研究，以便降生一個克隆的人類嬰兒。
(1) push ahead with短語在句中做“推進、推行”理解。例如：

無論發生什么情況, 我們都必須推行我們的增產計劃。
He promised to push ahead with economic reform. 他允諾繼續推行經濟改革。
We are pushing forward with our plan. 我們正堅決實施計劃。
(2) 辨析：push ahead，go ahead
兩個短語都有“前進”的意義，ahead是副詞，都是不及物詞組，但其區別也是明顯的。
① push ahead強調“向前推進、急速前進”
If we push ahead, we can get home before dark. 如果我們抓緊, 天黑前我們還能趕到家。
I want to push ahead on this project. 有關這個方案我想繼續取得進展。

8. Human life would no longer be unique; it would just be a product for sale. （page 43, lines 39-40）到那時人類生命將不再是獨一無二的了，將只是一個可供出售的產品。
(1) 辨析：unique, only
兩個詞做形容詞用都有“唯一的”的意思，但意義上區別較大。
① unique強調的是“區別和與眾不同”。例如：
The beauty of Dunhuang is unique in the world. 敦煌的美在世界上是獨一無二的。

(2) 辨析：for sale, on sale

She has put her house up for sale. 她現在的房子在出售。(狀語)

9. The human race is using up Earth’s resources. （page 43, line 41）人類正耗盡地球上的資源。
(1) use up “用光、耗盡”，use僅指動作過程，而use up則強調結果；英語中不少動詞都是如此。例如：

他知道怎樣使用這筆存款，用不了多久這筆錢會全部用完。
She didn’t want to end the relationship. But she finally had to end it up.

She had to dig the garden. As a result, an old coin was dug up in the garden.
她得把花園挖一挖, 結果在花園里挖出了一枚古硬幣。
(2) 辨析：use up, run out, run out of
表示“用完”時，這些詞組意義相同，但用法不同。
① use up是及物動詞短語，其主語是人。例如：
I’ ve used up all the glue. = All the glue has been used by me. 我把膠水都用光啦。
② run out是不及物動詞詞組，表示“被用完了（become used up)”，含被動意義，其主
語通常是時間、金錢、食物等無生命名詞。例如：
His money soon ran out. 他的錢很快就花完了。
Food supplies had run out towards the end of the trip. 在旅行快結束時，食物已經吃完了。
③ run out of 含有介詞of，作及物動詞用，“用完(=use up)”的意思。例如：

What if I've run out of money？我把錢花光了怎么辦？
10. I am in complete agreement with human cloning.（page 43, lines 49-50）我完全同意克隆人類。
(1) in agreement with 是一短語介詞，句中be in complete agreement with/about 是系表結構= quite agree with /about，意思是“完全同意；意見一致”，其介詞短語還可以在句中做其他成分。例如：

我發現自己的意見幾乎完全與托尼一致。

11. Seven years ago, my 10-year-old daughter died of heart failure.（page 43, lines 52-53）七年前，我10歲的女兒死于心臟病。
辨析：die of, die from

In a cold winter, many wild animals may die of hunger.
在嚴寒的冬天，很多野生動物會死于饑餓。

12. Question things you do not understand or that do not appear to make sense. (page 43) 對于你不了解的地方，或者似乎講不通的地方，要提出問題。
辨析：appear, seem
兩個詞做系動詞用都有“似乎、好像”的意思，含義似乎沒有多大差異，在句型結構上也基本一樣，有時候也能互換，微細的區別仍然值得注意。
① appear暗含“的確如此”含義，如果要表示某種判斷而得出的印象最好用appear。appear還可以是行為動詞“出現，顯現”的意思。例如：

看來他對音樂還有一定的鑒賞力。
They appear / seem to have misunderstood me. = It appears /seems that they have misunderstood me. 他們似乎誤解了我。

那個女演員三十五歲了，但是她看上去年輕得多。
② seem所表示的“似乎”或“看來”是以客觀的跡象為依據。還可以有It seems as if…句型，而appear則不能用于此句型。例如：
She seems a clever girl. = It seems that she is a clever girl. 她好像是個聰明的姑娘。
The baby seems (to be) asleep. = It seems that the baby is asleep. 那嬰孩好像是睡著了。

13. Why do some people think they have the right to go against nature?（page 45）為什么有些人認為他們有權與自然對抗呢？
辨析：go against, be against
他們基本同義，都有“反對、違背、不利于”的意思，仍有區別。
① go against sb. /sth 指“動作”。例如：
Don’t go against your parents /your parents’ wishes. 不要違背父母親的愿望。

② be against指“狀態”。例如：

14. I believe that strict laws should be put in place and governments should do more to stop human cloning.（page 45）我認為應該嚴格立法，政府也該采取更多的措施阻止人類克隆。
in place 在句中作狀語，意思是“在對的位置”、“在適當的位置”，其反義短語out of place“不合適; 不恰當”。在句中做表語有“合適的；恰當的”的意思。例如：

精講典析
1. This is the organ that controls the rest of the organs, just like the headmaster controls the school.（page 47）正是這個器官控制其他器官，正如校長控制學校一樣。
辨析：the rest, the other
兩者都有“其他的、其余的”的意義，但他們的區別較大。
① rest是名詞，即可指人也可指物，多指某一整體范圍之內的其他；the rest (of +名詞) 做主語時，謂語動詞可以用單數形式，也可以用復數形式，應視the rest所代替的那個名詞而定。例如：
I have got two bright students in the class, but the rest (of the students) are average.
這個班我有兩個聰明的學生，其余的平常。
I’ll keep one third of the money and the rest (of the money) is for you.

The beginning of the lecture was boring, but the rest was interesting.
開始部分演講十分枯燥，但是其余部分很有趣。
The rest of the bicycles are on sale today. 其余的自行車今日上市銷售。
② other是代詞，單數是兩者中的“另一”，復數才指“其余的(人或物)”；多指若干個個體中的其余部分。做形容詞用時亦是如此。例如：
She gave me one book last week and promised to bring the other on Wednesday.
她上周給了我一本書，并承諾星期三帶來另一本。

2. He is always working in his lab, trying to figure out all the mysteries that make him puzzled.（page 49）他總是在實驗室工作，盡力去弄明白所有使他困惑的奧秘。
figure out在句中意為“弄明白”; figure out還可表示“計算出”或“解決”。例如：
I just can’t figure him out. 我簡直摸不透他。
No one can figure out how the fire started. 沒有人弄得清這場火災是怎么引發的。
Could you help me figure out this problem? 你能幫我解決這問題嗎?

3. He must have been working too hard to notice!（page 49）他可能太專注于工作了，根本沒有注意到。
must have been working是情態動詞must 接動詞的現在完成進行時，表示對過去事情的推測，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.約翰肯定一直在踢足球，而瑪麗想必一直在做作業。
You must have been overdoing things a bit. 想必你一直以來都過于勞累。
3. I think we should be cautious and use good judgment when making decisions about cloning.（page 49）我認為在就克隆問題作出決策時，應當慎重行事，作出理智判斷。

If I had been more cautious, I might have done better. 我要是再謹慎一點，可能做得更好。
We should be cautious of strangers. 我們應該提防陌生人

② careful側重做事謹慎、留心，特別注意一些細節地方，著眼于“行動”。例如：
I begged him to be more careful. 我求他更謹慎些。
Be careful not to lose her address. 小心別把她的地址給弄丟了。
4. Although it involves some cost on your part, you will definitely agree it’s worth it! （page 49）盡管要支付一筆費用，但你肯定會認為是值得的。
(1) involve vt. "使卷入、牽涉、包括”，常用句型：involve sb. in 使參與〔陷入, 牽扯到〕
involve sb. with 與(某人)有密切關系。例如：
Buying an expensive car involved him in debt. 買一輛昂貴的汽車使他負債累累。
The project involved great expense. 那項工程開支巨大。
Don’t involve me in your quarrel. 不要把我卷進你們的爭吵中。

5. Treated with electricity, the cell tissue will split into several parts.（page 50）采用電療，這個細胞的組織會分裂成幾個部分。

詞匯奧秘
派生詞：前綴和后綴
詞根加上前綴或后綴而構成的新詞叫派生詞。通常前綴改變詞義，后綴改變詞性。如unbelievable一詞，其構成為：un-believe-able，前綴un- 表否定，形容詞后綴 -able表示“能夠的”，由此可推斷unbelievable的意思為“not able to believe”(難以置信的)。因此，掌握一些有關前綴的和后綴的知識對學習英語詞匯有很大的幫助。
1. 常見的前綴：
un-, im-, in-, dis-, ir-, non- 不；無
unfair不公平的 uncover揭開(蓋子) imperfect不完美的

語法知識
過去分詞
過去分詞作非謂語動詞用時，它具有形容詞和副詞的語法特征，在句子中做定語、表語、賓語補足語和狀語。過去分詞常表示被動意義；在時間關系上，過去分詞通常表示動作已完成；不及物動詞的過去分詞，不表示被動意義，只表示完成意義。
1. 用法
定語 The injured boy was sent to hospital.
He carefully studied the stamps collected in London.
表語 The glass is broken.
賓語補足語 You must get your hair cut.
狀語 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 作定語。單個過去分詞或復合詞一般放在所修飾的名詞前；過去分詞短語作定語時，則放在所修飾的詞后面，被修飾的詞和過去分詞應是被動的邏輯主謂關系即主動意義上的動賓關系或邏輯上的系表結構表狀態，都可以轉換成一個含有被動語態或系表結構的定語從句。例如：
man-made satellites（人造衛星），school-run factories（校辦工廠）
Students always grow with newly found knowledge. (page 47)
學生總是用新發現的知識伴隨著自己成長。
A surprised look appeared on his face when he heard that his friend had died．
當他聽說他的朋友死了，他臉上顯示出吃驚的表情。
A letter(that is) posted today will reach him the day after tomorrow．
今天發出的信后天他能收到。（post與a letter存在意義上的動賓關系。）
I want a child (that is) genetically related to me. (page 42, lines 24-25)
我想一個在基因上有關系的孩子。
② 作表語。表示主語所處的狀態; 除了系動詞be外，還有其他的系動詞也常見用過去分詞做表語。常用作表語的過去分詞有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)
真讓人失望。我想作業做完的時候，你會開心的。
He sounded so thrilled. (page 49) 他聽起來如此激動。
Otherwise you will get bored. (page 49) 否則你會覺得無聊。
I’m totally burnt out. (page 51) 我完全筋疲力盡了。
③ 作賓補。和賓語一起構成復合賓語，賓語是其邏輯主語。 have, make, get, keep, hear, feel, see, find, watch, notice, imagine, consider, want, wish, desire, like等動詞常接過去分詞作賓補。
He is always working in his lab, trying to figure out all the mysteries that make him puzzled.（page 49）他總是在實驗室工作，盡力去弄明白所有使他困惑的奧秘。
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 作狀語。常修飾謂語動詞所表示的動作，可表示時間、原因、方式、伴隨等，其邏輯主語是句子的主語，主語和過去分詞同樣構成邏輯主謂的被動關系，可以同相應的狀語從句進行轉換。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.
采用電療，這個細胞的組織會分裂成幾個部分。(表時間)
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．(表條件)
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. (表條件)
⑤ with+名詞(或代詞)+過去分詞
在介詞with的復合結構中，過去分詞和前面的名詞或代詞構成邏輯主謂的被動關系, with復合結構在句中做狀語。例如:
I sat in my room for a few minutes with my eyes fixed on the ceiling.
我在房間坐了一會兒，眼睛盯著天花板。（表伴隨）
She had to walk home with her bike stolen. 自行車被偷，她只好步行回家。（表原因）
I had the TV on with the sound turned down. 我讓電視機開著，但音量調低了。（表方式）
2. 分詞的獨立結構
當過去分詞做狀語表時間、條件、讓步或方式時，可以在分詞前加上相應的連詞when /while / before /after /since /if /unless /though等；在狀語從句中，當主從句的主語一致且謂語中含有系動詞或助動詞be時，從句的主語和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. 過去分詞與現在分詞完成被動式的用法比較
現在分詞的完成被動式作狀語，有時可與過去分詞換用。過去分詞側重于動作的被動，現在分詞完成被動式側重于動作的完成(即強調與謂語動作的先后關系)。如果不強調動作的先后，只強調動作的被動，這時只用過去分詞，不用現在分詞完成被動式。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. 作狀語時表示主動意義的過去分詞
有些過去分詞因為來源于系表結構，其本身已經是形容詞了，作狀語時不表被動而表主動意義。常見的這類詞有：lost（迷路的、迷失的），seated（就座的），hidden（隱秘的、隱藏的），absorbed in（投入的、全神貫注的），born（出生的、產生的），dressed in（穿戴好的），tired of（厭倦的、厭煩的）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.

這兩個詞都有 “多數，大多數”的意思，但區別較大。

(3) 辨析：seek, search for, look for, hunt for

At that very moment the telephone bell rang. 恰好在那個時候，電話鈴響了。
These pills are the very thing for your cold. 這些藥丸治你的感冒正合適。
(2) resistant to是形容詞短語，意為“對……有抵抗力的”或“耐……的”, 在句中做后置定語。例如：
A healthy diet creates a body (that is) resistant to disease.
保健飲食有助于增強體內對疾病的抵抗力。
We need building materials which are resistant to heat. 我們需要耐熱的建筑材料。
(3) 辨析：be harmful to, harm, do harm to, be bad for

Pollution does great the harm to the environment. 污染對環境造成損害。
It’s unlikely to do much harm to the engine. 這不大可能會嚴重損壞發動機。
The drought did a lot of harm to the crops. 干旱給莊稼帶來許多危害。
④ be bad for除還有“對……有害”的意思外，還有“不利于“的意思。例如：

Often they do not realize that the choices they make are bad for / harmful to the environment. (page 58, lines 23-24) 他們往往沒意識到自己所做的選擇對環境是有害的。
7. So far, research has been limited to increasing production profits, rather than ensuring safety.（page 57）到目前為止，研究一直局限于提高生產利潤，而不是確保安全性。

The farther hill is five kilometers away. 那座更遠的小山在五公里以外。(adj.)
I can throw the ball farther than you can. 這個球我能比你扔得遠。(adv.)

The church is much further / father than you think. 教堂比你想像的遠得多。(adj.)
For some time I had wanted to move further / farther from London. (adv.)
有一段時間我曾想要搬到離倫敦更遠的地方。

Personally speaking, I ’m in favour of the scheme. 就本人而言，我贊同這個計劃。

“in +名詞+ of”結構的常用短語還有：

10. Most of the time it turns out that humans are not really profiting when they damage the environment.（page 58, lines 29-30）多數情況下的結果就是，人類在破壞環境之際并沒有真正受益。

11. It is mankind’s responsibilities to find solutions that are acceptable for everyone, and everything. (page 58, lines 32-33) 找出對任何人、任何事物都可以接受的方案，是人類的責任。
① 這是一強調句，強調部分是句子的主語mankind’s responsibilities to find solutions
② be acceptable for / to sb. 可理解為“為……所接受、對……適合”。介詞for多用來指物，而to較為多見用來指人。例如：

課題實踐
How to write a formal letter
1. 正式信函的寫作原則
由于電子郵件的普及，書信寫得越來越少，但一旦我們要寫，那一定是很重要的信件，比如說求職信、投訴信等。因此，我們要讓書信給讀者留下深刻印象，起到預期的作用。寫書信時我們要遵循下列原則：
in the correct format 格式正確
short and to the point 簡短，切中要害
relevant 具有相關性
free of any grammatical or spelling mistakes 沒有語法和拼寫錯誤
polite, even if you’re complaining 有禮貌，哪怕是投訴信
well presented陳述恰當
2. 正式信函的寫作格式要求
正式信函要求格式規范，要包含信件構成的各個要素：
寫信人地址：在信的右上角
收信人地址：在信的左上角，接著寫信人地址下面寫。
日期：可在左邊，也可在右邊，月份不用縮寫
稱呼：用“Dear+姓”，不知道姓名時用Dear Sir或Dear Madam。不知道是Mrs 還是Miss時，可以使用Ms。
結尾：使用Yours Faithfully，Yours Sincerely結尾。
簽名：在左下方，與正方開頭對齊。商務信件中，須在簽名后列出自己所屬的公司，自己的職位及公司地址，電話簿。
3. 信的內容
第一段簡要說明寫信的目的，是問詢、投訴還是請求等。
第二部分可以是一段，也可以是幾小段，是書信的主體內容。英文信不宜過長，因此要
簡明扼要說明事情。要清晰、緊湊，邏輯性強。
最后一段正式書信中往往寫明你希望收信者采取什么行動。常用結束語有：
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. 靜候佳音
I look forward to our next meeting in Los Angeles. 期待我們下次在咯杉磯的會面。
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，我們會非常樂意給
你寄過去 。
The help you give me is sincerely valued. 你給我的幫助非常寶貴。
I hope everything will go well with you. 我祝你萬事如意。
Please let us know if you want more information. 如果需要更多的信息，請盡管通知我。
I hope you always enjoy yourself. 我希望你永遠開心。
I wish you every success in the coming year. 我祝你來年一切如愿。
Please remember me to your family. 請代我向你的家人問好。
All the best. 祝你萬事如意。
With love and good wishes. 給你最好的祝愿。
現在，假如你叫Louise Longford，是個健美教練，想要去一家叫做Fitness First的公司應聘，請給Mr G. Sands寫一封求職信。
首先確定信的格式；然后在第一段說明寫信的目的是應聘健美教練；中間段落列出自己的優點，說明自己能勝任這份工作；最后一段寫出自己的希望。
Louise Longford的求職信：
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
書信寫完后，要根據上述原則進行檢查，以保證書信質量。相信看過你寫的求職信，Mr Sands會很樂意招聘你。
