Its elegant products and smart operating system, and its struggles against IBM and Microsoft in the 1980s, are especially appealing in a country that prides itself on being fashionable, clever and revolutionary. Apple's two stores in central Paris lie in locations that are dear to French hearts—under the Louvre and directly opposite the Opera.But the love affair is fading—in official circles at any rate—as concerns grow that the technology giant's market control does harm to a business in which French companies have been successful: designing applications for mobile devices. The government has complained Apple's eviction（逐出）from its application store of a popular product developed by a French start-up firm—AppGratis. AppGratis offers its users one free application a day, charging developers for making products known to a wider audience.Simon Dawlat, the boss of AppGratis, thinks the application performs a valuable service in providing "a continuous stream of editorial picks" of the highest quality from the complex world of applications. Around 12 million people have downloaded AppGratis, he says, and perhaps a quarter of them at least consider the chosen application each day. First marketed outside France in 2012, AppGratis has at times been the most popular free entertainment download for devices running Apple's iOS operating system in 78 countries including the United States, according to App Annie, a market-research firm. In early 2013 AppGratis had raised more than $13 million for an expansion that has now been put on hold.Apple says AppGratis disobeyed its bans on promoting other publishers' products and on using "push" notifications（通知）for paid marketing. Apple dislikes apps that serve as shopfronts for other ones. It worries that "app-discovery" products can help developers with deep pockets move their applications up the league tables and disturb the market. So it is rather puzzling that a version of AppGratis for iPads was approved less than a week before the mobile-phone version was evicted from the app store, and that other app-discovery applications are still available there. Perhaps AppGratis was growing too popular too quickly and that was its real fault.Fleur Pellerin, France's digital-economy minister, blamed Apple on April 11th for its cruel treatment of AppGratis and spoke of tightening the regulation of giant Internet firms, in France and at European Union level. The country's competition authority is looking into the relationship between app stores—Google's no less than Apple's—and developers. The French have a lengthening list of grievances（抱怨）against the Internet giants, includingtheir failure to pay serious taxes, the refusal of Microsoft's Skype to register as a telecoms operator and Twitter's refusing to name those behind an outburst of racists. Ms Pellerin may not manage to cut them down to size; others have tried and failed. But for Apple and France, at least, it is looking increasingly like the end of the affair.（1）What can been inferred from Paragraph 3?A AppGratis is a branch company of Apple.B AppGratis' new application is considered a threat to Apple.C The products of AppGratis are considered of low quality byApple. D AppGratis develops very well in France.（2）In the last paragraph, many big Internet companies are mentioned to show that ______.A these companies must cooperate with French companies to seek developmentB the development of these companies prevents that of French domestic companiesC French government is starting a new supervision policy toward these companiesD big digital companies are facing a brighter future in France4. "The Book That Can't Wait"is a great new idea that seeks to strengthen bonds between fi rst time writers and their readers by getting their books read quickly．Argentinean independent publishers Eterna Cadencia are publishing a collection of short s tories by new South American authors using special ink that slowly disappears once it comes in contact with sun and air, completely vanishing within 2months after the book has been op ened．This makes for an interesting approach to motivating book buyers to read books mor e quickly, giving first-time authors the attention they need to survive．"The Book That Can't Wait"tackles an important problem for new authors: How to get read ers．The creative independent publishers teamed up with DRAFTFCB in the city of Buenos A ires to develop this project．"Books are very patient objects．We buy them, and then they wait for us to read them．Da ys, months, even years．That's OK for books, but not for new authors．If people don't read t heir first book, they'll never make it to a second, "says the project coordinator Tito Santana． That's why Etema Cadencia, which also runs its own bookstore, has decided to create some thing different to launch its new authors into the market．It presented its first"The Book Th at Can't Wait"for the critics and the press last month．The invention is a success．Hundreds of people came to the bookstore to pick up a copy．To help spread the word, they gave away the first edition to customers for free．The very same day it was released, the publishing ho use claimed that it received thousands of requests for more copies of the book．So it will pri nt a new edition later this month to satisfy the demand．And the best result? This time they have the guarantee that their new authors will be read．The company plans to use the book as a platform for other titles, because they believe there is a lot of literature out there that do esn't deserve to wait on the shelf．And these books won't wait at all．（1）The main purpose of publishing"The Book That Can't Wait"is to________．A sell more books．B make it fun to read．C invent a new kind of book．D getnew authors'books read quickly．（2）The DRAFTFCB mentioned in Paragraph 3is most probably________．A an organization involved in the project．B a new South American author．C an i ndependent bookstore．D an area of Buenos Aires．（3）By saying"Books are very patient objects"in Paragraph 4，Tito Santana actually means________．A books never know when you read them．B books must be read very carefully．C books can usually be read at any time．D books can sometimes have emotions．（4）What can we learn from the passage？________A Light and air can make the books disappear within two months．B The approach has only been applied to works of some new authors．C Books printed using the new techn ology have been best-sellers． D The company will publish all its books in the future using the new ink．（5）What is the author's attitude towards this new kind of book？________A Approving．B Doubtful．C Uninterested．D Opposed．5. At 10: 35a．m．on December 17, 1903, two brothers from Ohio flew the first successful airplane for 12seconds and 120feet along a beach in Kitty Hawk, North Carolina．With Orvil le flying first, the brothers took turns as pilot, and they flew three more times that day．On t heir fourth try, they managed to go 852feet in 59 seconds--an amazing feat at the time．The two brothers had invented powered flight．Orville and Wilbur Wright owned a bicycle shop in Dayton, Ohio．Although they had not g one to school to learn about airplanes or engineering, they were good mechanics．By repairi ng bicycles, they had learned how gears and pulleys worked．They also learned to take caref ul notes about what they saw．Each time they made a new design and tested a machine, the y took notes and made drawings．They would study these to figure out what they could do b etter the next time．Before the Wright brothers flew, they did many things to prepare for this extraordinary ach ievement．They read everything they could find about air, balloons, and kites．Then they m ade careful sketches of what they wanted to build．They began by making model kites to lea rn how air flowed over wings．They made them bigger and bigger until they had a glider-a kite that is big enough to hold a person, but with no engine．The Wright brothers made thr ee gliders before building their first airplane．Each time they made a glider, they would test it, make careful observations, and then improve their design．When they made a glider that flew well, they added an engine．This step was harder than i t sounds, because they had to find an engine that was both light-weight and powerful．The engines that they could buy were either too heavy or too weak, so they asked their friend Charlie Taylor to help them build one．The first engine that Charlie built broke almost immediately, but the second one worked well．After Orville and Wilbur installed the engine in their plane, they were almost ready．They simply had to wait for the perfect day with just the fight amount of wind．On the morning ofDecember 17, 1903, they had their chance．And the airplane flew into history．（1）What was the speed of the first flight？________A 10feet per second．B 120feet per minute．C 12feet per second．D 1200fee t per hour．（2）What can we learn about the Wright brothers from Paragraph 2？________A They had little formal education．B They owned a successful business．C They were very thorough in their work．D They had experienced many failures．（3）The brothers constructed a number of kites in order to________．A test the materials they would use for their plane．B prove that building a flying mach ine was possible．C see which shape could support the most weight．D improve th e design of their plane's wings．（4）Which of the following is true according to the passage？________A The Wright brothers built all the parts of their first plane．B Wilbur Wright flew 852f eet on December 17，1903． C There was no wind on the day the Wright brothers flew． D Orville Wright went on to become a professional pilot．（5）In what order did the following events occur？________A c，f，e，b，a，d.B b，c，a，f，d，e．C b，a，f，e，c，d.D d，e，a，f，c，b．6. Expensive perfumes （香水） come in tiny bottles, but many hide a whale-sized secret． To perfect a particular smell, perfume-makers often use an ingredient that comes from sperm whales, called ambergris．But using ambergris, which helps a perfume last longer, is strongly opposed by many people who think it is wrong to kill whales just so we can smell sweet．Joerg Bohlmann is neither a perfumer nor a whale expert．He's a plant biologist at the University of British Columbia in Canada．But his discovery of a new plant gene （基因） might push whales out of the perfume business．The gene comes from fir trees, found throughout North America and commonly used as Ch ristmas trees．The trees produce a chemical that can be used in perfume in place of ambergr is--but with a catch．"There's a problem that many people wouldn't consider．In the tree, the chemical is mixed with many others．That makes separation a challenge, "Bohlmann says．"It's like trying to i solate sugar from a biscuit．"This is where science becomes useful．When Bohlmann learned that fir trees produce the ambergris-like chemical, he decided to use his gene know-how to find the instructions for how to make the ambergris-substitute．Bohlmann found that gene and took it out of the tree cells．Then he did something that mi ght sound strange to someone who doesn't work in genetics: Bohlmann put the gene from the tree into yeast （酵母） cells．Yeast may sound familiar because it's used to make things like bread, wine and beer．Biol ogists like to work with yeast because it easily adopts new genes and changes its features an d behaviour．When Bohlmann put the fir tree gene into the yeast, the yeast started making t he same chemical that had been produced by the tree．Perfumers pay big money for ambergris because it is a fixative, which means it holds a sme ll in place on a person's body．"Cheap perfumes smell good in the first hour or so and then everything is gone, "explains B ohlmann．"But expensive perfumes are much more stable．Their smell lasts much longer, f or hours or even a day after you apply them．"The new chemical, made from the tree genes, can be used as a fixative, too．And using yea st to make it is far cheaper than acquiring ambergris．Bohlmann admits he never thought he'd get into the perfume business．But now, he says, producers have been calling to find out how to use his technology in new perfumes．（1）It can be inferred from the passage that if a perfume contains ambergris，________A its user probably supports whale hunting．B its smell will last for about an hour．C there will be a whale symbol on the bottle．D it is probably very expensive．（2）The underlined expression"with a catch"in Paragraph 3means________A being difficult to hold.B having a hidden problem．C needing further testing.D being too similar．（3）According to the passage，why are yeast cells often used in genetic research？________ A They can take on the characteristics of other genes． B They can reproduce much fast er than other cells． C They share some of the qualities of plant genes． D They're much cheaper to use than ambergris．（4）What can we learn about Joerg Bohlmann from the passage？________A He is opposed to whale hunting．B He made his discovery during Christmas．C He has worked in the perfume industry for many years．D He has previously done gene tic research．（5）What is the best title for the passage？________A The Christmas tree's secret．B The sweet smell of success．C Whale-free perfume． D Save the whale．第二节信息匹配（共1小题；每小题10分，满分1O分）阅读下列应用文及相关信息，并按照要求匹配信息．7.

underst and the causes of the problem and find a solution．In the last 10years，studies have found an alarming increase in：•Obesity--The number of overweight middle school students has doubled．Poor diet，especially the overeating of junk food and the overdrinking of soft drinks，and the lack of physical activity are identified as the main reasons for this problem．•Poor eyesight--More students now wear glasses and from an earlier age．Long hours of study and heavy us e of computers and mobile phones are most commonly blamed．•Stress--Students feel under more pressure to succeed than ever before．The long hours of study and homework they must do to achieve success，plus pressure from parents and schools are the main causes．Some have suggested including Physical Education （P．E．） in the Gaokao as a possible sol ution to students'health problems．They say this will force students to be more active，play sports and therefore lose weight．Others，however，oppose the idea，saying that adding one more test to the Gaokao would only increase students'workload and s tress and would actually worsen their overall health．Although there is no easy answer，all agree that something must be done to stop the serious decline in students'health．[写作内容]1）以约30个词概括这段短文的内容；2）然后以约120个词就"健康与学习"的话题进行写作，内容包括：①你是否赞成体育人高考及原因；②健康与学习的关系；③你认为还有什么方式可以帮助学生提高身体素质．[写作要求]1）在作文中可以使用自己亲身的经历或虚构的故事，也可以参照阅读材料的内容，但不得直接引用原文中的句子；2）作文中不能出现真实姓名和学校名称．[评分标准]概括准确，语言规范，内容合适，篇章连贯．2013年广东省广州市高考英语二模试卷答案1.

Version one：Using solar panels to get energy from the sun，solar cars look similar to ordinary cars，but they have several advantages．They produce little noise and almost no air pollution，which is great for the environment．Also，as they're comparatively smaller，solar cars are easy to drive and park．However，solar cars are much more expensive to buy than normal cars，and they're much less powerful，with a top speed of only 70 km/h．The biggest problem of all is that they can only be driven about 100 km before their battery needs recharging/to be recharged．Version two：Solar cars，which get their energy from the sun through solar panels，look similar to ordinary cars，but they have several advantages．They produce little noise and almost no air pollution，so they're quite good for the environment．Also，as they're comparatively smaller，solar cars are easy to drive and park．However，not only are they much more expensive to buy than normal cars，they're also less powerful，with a top speed of only 70 km/h．The biggest problem of all is that they can only be driven about 100 km before their battery needs recharging/to be recharged．9.

It is often said that “a healthy mind needs a healthy body.” With good health, you have enough energy to perform at your best. I think the core issue is how to get students healthier. Besides a test, I think schools should do things such as stop selling the soft drinks and junk food, as well as give students less homework and more time for outdoor activities.
Using solar panels to get energy from the sun, solar cars ,(或Solar cars, which get their energy from the sun through solar panels) ,look similar to ordinary cars but they have several advantages. They produce little noise and almost no air pollution, which is great for the environment. Also ,as they are comparatively smaller, solar cars are easy to drive and park. However, solar cars are much more expensive to buy than normal cars, and they’re much less powerful, with a top speed of only 70km/h. The biggest problem of all is that they can only be driven about 100 km before their battery needs rechs passage lists some of the causes for the decline of Chinese students’ health and discusses one possible solution to the problem –including P.E. in the Gaokao. In my opinion, it’s unreasonable to include P.E. in the Gaokao. While students may spend more time doing physical exercise to prepare for the test, this doesn’t mean they will improve their health. On the contrary, additional test pressure and excessive exercise may make their health worse. Moreover, it’s unfair to students born with health problems and to those not gifted in sports.

实验设计和结果如下表所示(中药制剂和四环素都用生理盐水溶解)，请据表分析回答：(1)若要观察小鼠皮下脂肪细胞中的脂肪颗粒，可用染色。
(2)现有健康的体重相近、发育状况相同的雌雄小鼠各100只，按上表的实验设计应如何对这些小鼠进行分组? 。
表中所示的实验自变量有。
(3)甲组和乙组对照可说明。
上表实验结果可初步说明该中药制剂能对小鼠起什么作用? 。
(4)研究人员认为，还需要观察中药制剂对小鼠(没有注射四环素)肝脏脂肪含量的影响。
请完善实验设计并回答问题：1．实验步骤：①步骤一：按上表所示的实验设计的要求增加3组小鼠，并编号。
②步骤二：这3组小鼠除每天喂养相同的饲料外，每天还需分别喂，共11天。
同时在第8至11天注射等量生理盐水，保持其它条件适宜且相同。
③步骤三：测量并统计实验结果。
Ⅱ．讨论：①将得到的实验结果与上表的组的结果进行对照，然后得出结论。
②步骤二中需要“保持其它条件适宜且相同”，其原因是。
