11.Gold
India is the world's largest market for gold jewellery.In much of Asia,the Middle East and India,around two-thirds of the jewellery purchased is used as a way of saving money as well as being worn as a decorative item.The use of jewellery as a way of saving money is often important in rural areas where finding a bank is difficult or even impossible.People buy gold because its value stays strong even when the value of money goes down.
Gold jewellery has often been a woman's only valuable possession,and in some families this is still true.A woman's gold can therefore be her only protection against personal misfortune.Today,all around the world,sales of gold jewellery have grown by over 20% per year,because everyone is confident that gold won't lose its value.Demand for gold is so high that gold mines cannot supply enough.
Gold's function as a decoration,as jewellery,has been evident for thousands of years.Since the earliest times,the beauty and richness of gold,along with the fact that it does not change its colour,has meant that it has always been the favourite metal of jewellers.The earliest gold jewellery dates from the Sumerian civilisation that was at its most powerful around 6,000years ago.In the Middle Ages,ancient people attempted to make gold from other metals.They used gold in medicines designed to fight old age and prolong life.
Gold also performs important functions in many aspects of everyday life.It does not react when it comes into contact with other substances and this,along with other unique properties,makes it useful in medicine and many other areas that we consider essential to our modern lives.
During heart surgery,gold-covered"stent"are put into blocked arteries to help the flow of blood.These gadgets need to be carefully positioned.Gold is ideal for this because it shows up clearly on X-rays and can easily be located by doctors.A pacemaker,a device inserted in the body to keep the heartbeat regular,also contains gold.Gold is used in all of these applications because of its high level of reliability.Gold also helps doctors to deliver precise doses of powerful drugs to the parts of the body where they are required.
Gold has many other applications in modern life as it conducts electricity very efficiently.The standard touch-tone telephone contains 33contacts made from gold.Air-bag systems fitted in more than 30million cars around the world rely on gold-coated electrical contacts.And every time you touch a key on your computer it strikes a gold circuit that sends your command to the computer's microprocessor.In fact,you have probably never realised how much gold there is in your everyday life.

(Note:Answer the questions or complete the statements in NO MORE THAN TEN WORDS.)
78.Compared with money,people prefers gold because ofits stroger value than money.
79.Gold were used in medicines because ancient people believed it couldfight old age and prolong life.
80.Why can gold be used in pacemaker?Because it has a high level of reliability
81.What makes the application of gold in electronic products possible?It is because it conducts electricity very efficiently.

分析 文章大意:本文介紹了金子在古代和現(xiàn)代的各種用途.除了用作首飾,在古代人們就知道在貨幣貶值的時(shí)候金子的價(jià)值也是穩(wěn)定的.所以人們更喜歡儲(chǔ)藏金子以達(dá)到保值的作用.在中世紀(jì)人們把金子用于藥物,因?yàn)樗麄冋J(rèn)為金子有對抗變老和延長生命的作用.金子在現(xiàn)代社會(huì)因?yàn)樗行У貙?dǎo)電性和它的穩(wěn)定性,有了更多的其他的用途.例如在心臟起搏器和造影技術(shù)上的運(yùn)用以及電力設(shè)備中的作用

解答 78.Compared with money,people prefers gold because of its stroger value than money.根據(jù)第一段的末尾 People buy gold because its value stays strong even when the value of money goes down.可以知道即使在貨幣貶值的時(shí)候金子的價(jià)值也是穩(wěn)定的.所以人們更喜歡儲(chǔ)藏金子而不是貨幣.
79.Gold were used in medicines because ancient people believed it couldfight old age and prolong life.根據(jù)第三段的末尾They used gold in medicines designed to fight old age and prolong life.可以知道古代人把金子用于藥物是因?yàn)樗麄冋J(rèn)為金子有對抗變老和延長生命的作用.
80.Because it has a high level of reliability.根據(jù)第五段第三行Gold is used in all of these applications because of its high level of reliability.可以知道金子能有這些用途是因?yàn)樗鼧O高的可信賴性,也就是它的穩(wěn)定性.
81.It is because it conducts electricity very efficiently.根據(jù)最后一段第一行Gold has many other applications in modern life as it conducts electricity very efficiently可以知道金子在現(xiàn)代社會(huì)有其他的用途是因?yàn)樗行У貙?dǎo)電性.

6.By Jerilyn Watson Broadcast:February 14,2010.
Welcome to THIS IS AMERICA,in VOA Special English.I'm Steve Ember.And I'm Faith Lapidus.February fourteenth is Valentine's Day.So this is a good time to play some love songs as we explore the subject of dating.
VOICE ONE:Valentine's Day is a special time for love.Millions of people will receive flowers,chocolate or some other gifts.Others might get just a phone call or an electronic message from someone they care about.Still others would be happy just to have someone special in their life on Valentine's Day.
VOICE TWO:Traditionally,there are many ways for people to meet.Some meet at work.Others meet by chance.Still others look for help from services that bring people together.Friends and family members might offer to help.They might plan a blind date.This is a meeting between two people who have never seen each other before.A lot of people try to improve their chances by looking in places where people with similar interests go,such as a place of religion,a bookstore,health club and sports team where men and women play together.

A.Valentine's Day                     
B.how to make friends in daily life.
C.dating between men and women        
D.how to keep your marriage.

16.I'm a thin girl sitting in the examination hall among my classmates with a sheet of questions in front of me.The only difference between my classmates and me is that they are all busy filling out their sheets,while I am just sitting,staring at the wall in front of me.
  With no words coming to my rescue,I helplessly glance down at the title of the essay:"My Father".
  Since I do not have a clear impressionof him,I can only describe him on the basis of what I have heard from my mother and other relatives.They all told me that he was caring,hard-working,a man of his word and did everything to keep his family happy.They stopped talking about him as suddenly as he disappeared from our lives.He went to work one day and never returned.My mother ran from hospitals to police station and even to mortuaries (太平間) but found no trace of him.He was gone as if he never existed.
  While growing up I gradually knew he was taken away by security forces because he was against the state.I do not know how far that is true.He was an ordinary manworking day in and day out to make ends meet and put food on our table.He was hardly concerned about the state of affairs in Pakistan.
  I understand that my teachers are probably expecting me to writeflowery words about him but how I can be expected to write about a man who never existed.Perhaps,it would be unfair to say he never existed.He still does in my memories.He was a fruit businessman and owned a shop.Every evening he would return from work with dates (棗) or sweets,and his hands were never empty.I also remember that he took me to the Koh-eMuras once; he told me that this was a very sacred (神圣的) place,asking me to fold my hands and ask Allah for whatever I wanted.I remember folding my hands and praying hard for every day to be a happy day.
注意:
1、所續(xù)寫短文的詞數(shù)應(yīng)為150左右.
2、應(yīng)使用5個(gè)以上短文中標(biāo)有下劃線的關(guān)鍵詞語.
3、續(xù)寫部分分為兩段,每段的開頭語已為你寫好.
4、續(xù)寫完成后,請用下劃線標(biāo)出你所使用的關(guān)鍵詞語.
Paragraph 1:
    Ever since I have lost him,I have been faced with a deep sense of loss-a feeling which is
difficult for me to describe in words.______________________________________________
Paragraph 2:
   Strangely,I am just as hopeful as I am angry._____________________________________
