1．I am going to buy the overcoat if the shopowner       lower the price．（　�。�
A．mustB．shouldC．couldD．will

分析 如果店主愿意降低價(jià)格，我打算把這件外套買下來(lái)．

解答 答案是D．本題考查情態(tài)動(dòng)詞will表示"意愿"．情態(tài)動(dòng)詞will 可以表達(dá)"意愿"，這時(shí)可以用在條件狀語(yǔ)從句中．本題表達(dá)的是"如果店主愿意降低價(jià)格"，所以答案是D．must表示"必須；肯定；偏要"；B項(xiàng)should 表示"應(yīng)該；萬(wàn)一；竟然'"；D項(xiàng)表示"可能；能夠"，所以A、B和C均不符合題意．

點(diǎn)評(píng) 要在正確理解情態(tài)動(dòng)詞的基本含義的基礎(chǔ)上，整體理解語(yǔ)境中的情感態(tài)度，做出合理的判斷．

9．Online clothes shoppers will be told exactly what size is best．for them using new software which combines with their web camera or smart phone to form a"3D tape measure"．
Scientists from Surrey University and design experts from the London College of Fashion are developing a program which can take precise （精確的） waist，hip，chest and other measurements from camera images．
Using the person's height as a starting point，the software will be able to build up a 3D image and estimate their size at various different points on the body，based on their overall proportions．
The result will be a more accurate sizing guide than previous systems based on waist size or a"small/medium/large"scale，which rely on limited measurements and the buyer's perception of their own body size．
Shoppers and retailers（零售商）who choose to sign up for the project could save millions of pounds a year in postage costs by removing the need to order multiple sizes of the same garment（服裝） and send back ill-fitting clothes，researchers claimed．
The project，sponsored by the Engineering and Physical Sciences Research Council（EPSRC），is expected to be brought to market within two years．
After choosing an item，the shopper will activate the software，enter their height，stand in front of their webcam or smart phone in their underwear and take a photograph．
The software will not store or transmit the image to the internet，but will use it to judge the person's dimensions at various points on their body．
Philip Delamore of the London College of Fashion said："The potential benefits for the fashion industry and for shoppers are huge．Currently，it's common for online shoppers to order two or three different sizes of the same item of clothing at the same time，as they're unsure which one will fit best．"
51．What is the essential part of a 3D tape measure？A
A．a(chǎn) software                           B．a(chǎn) webcam
C．a(chǎn) microphone                         D．a(chǎn) smart phone
52．What can we learn about the 3D tape measure？C
A．It will store or transmit the image to the internet．
B．It is based on the buyer's perception of their size．
C．It will be a co-working production．
D．It uses a person's weight as a starting point．
53．Compared with the traditional sizing system，a 3D tape measure isB．
A．quicker                              B．more precise
C．more beautiful                       D．more vivid
54．How can the 3D tape measure benefit online shoppers？D
A．Online shoppers will get their ordered garment in time．
B．Online shoppers will get their ordered garment more quickly．
C．Online shoppers will get an ordered garment of high quality．
D．Online shoppers will get an ordered garment to their measure．
55．What is the right order for a shopper to form a 3D tape measure？C
①to take a photo with a webcam
②to activate the software
③to enter his/her height
④to judge his size by analyzing his image

16．The Hard Truth
One day，Marissa noticed a spiderweb，shining in the sunlight．A spider was spinning （36）A on it．The spider wasn't trying to be something else，like a butterfly or a bee，Marissa thought．It was happy to be exactly what it was and to do what it was good at．
What came naturally to Marissa was （37）B．She could paint or draw all day long and never get bored．However，a few weeks ago Marissa signed up for high jump．Because her mother had been a high jump （38）Din school，she thought it would make her mother happy．But now she （39）A that however hard she worked，she would never be a high jump star like her mother．
One night，halfway through her homework，Marissa fell （40）C．When she woke up，the clock read 1：00A．M．Marissa got into a panic．There was still so much （41）A to do，but she really needed her rest for track practice．Marissa had always been a good student，but now track was risking her （42）C．
Then a dark thought crossed Marissa's mind．If she （43）D some of her classes，she would be off the track team．That was one way to solve her problem．
After a week of （44）B her homework，letters had been mailed out to parents listing grades，and Marissa knew the letters would show that her grades had （45）C a lot．She walked home with slow heavy steps，knowing her （46）A plan had worked．
Just as Marissa had （47）B，her mother was waiting with the （48）D in her hand．"What's happening to your grades？And more importantly，what's happening to you？"she asked．
With tears in her eyes，Marissa admitted her （49）C．"I only joined the track team to make you proud of me．I hated it，（50）D I didn't want to disappoint you．I thought if I were failing in my classes，Coach would kick me off the team．What a （51）C I've made of everything．"
Marissa watched her mother's face turn from anger to （52）B．"Marissa，I was always proud of you．You didn't need to do the high jump to make me happy．Now you have a lot of hard work in front of you because you made a bad （53）D．"
Marissa thought again about the spider．She realized she had lost sight of her （54）C and twisted her web．Now she had to go back and （55）A that web．

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．
