12．Sustainable development is applied to just about everything from energy to clean water and economic growth，and as a result it has become difficult to question either the basic assumptions behind it or the way the concept is put to use．This is especially true in agriculture，where sustainable development is often taken as the sole measure of progress without a proper appreciation of historical and cultural perspectives．
To start with，it is important to remember that the nature of agriculture has changed markedly throughout history，and will continue to do so．Medieval agriculture in northern Europe fed，clothed and sheltered a predominantly rural society with a much lower population density than it is today．It had minimal effect on biodiversity，and any pollution it brought about was typically localized．In terms of energy use and the nutrients captured in the product it was relatively inefficient．
Contrast this with farming since the start of the industrial revolution．Competition from overseas led farmers to specialize and increase yields．Throughout this period food became cheaper，safe and more reliable．However，these changes have also led to habitat loss and to diminishing biodiversity．
What's more，demand for animal products in developing countries is growing so fast that meeting it will require an extra 300million tons of grain a year by 2050，yet the growth of cities and industry is reducing the amount of water available for agriculture in many regions．
All this means that agriculture in the 21st century will have to be very different from how it was in the 20th．This will require complete thinking．For example，we need to move away from the idea that traditional practices are inevitably more sustainable than new ones．We also need to abandon the notion that agriculture can be"zero impact"．The key will be to abandon the rather simple and static measures of sustainability，which centre on the need to maintain production without increasing damage．
Instead we need a more dynamic interpretation，one that looks at the pros and cons of all the various way land is used．There are many different ways to measure agricultural performance besides food yield：energy use，environmental costs，water purity，carbon footprint and biodiversity．It is clear，for example，that the carbon of transporting tomatoes from Spain to the UK is less than that of producing them in the UK with additional heating and lighting，but we do not know whether lower carbon footprints will always be better for biodiversity．
What is crucial is recognizing that sustainable agriculture is not just about sustainable food production．

10．Italians like to say that when it comes to alcohol，they have a sipping （小酌） culture rather than a drinking culture．That means that while Italians may enjoy a glass of wine or beer，they don't usually get very drunk．
That's not true any more．The new study by the Italian National Health Institute found that 63 percent of Italians under age 18 get drunk on the weekends．Now，the city of Milan has created a law that will stop anyone under 16 from buying alcohol．Anyone who sells or gives alcohol to a person under 16 can be fined up to    700．Young people who feel that the new law is unfair should go to the US for some perspective （观点）．The US has the highest drinking age in the world； It's illegal for anyone under 21 to buy alcohol，and stores or restaurants that are caught selling alcohol to people under the legal age risk losing their licenses，
Many young Americans complain that the drinking laws are unfair； They are allowed to vote in elections and join the army at age 18，so why wait another three years just to buy a bottle of beer？
These young people have found help in an unusual place．Last year，more．than 100 presidents of US universities joined together to ask lawmakers to consider changing the drinking age．They argued that the law doesn't stop underage college kids from getting drunk-it just makes them want to drink more．
For now，the law seems unlikely to change．But US teenagers who want alcohol can go north 10 Canada，where the drinking age is 18-19，or south to Mexico where the legal age is 18．Throughout much of Asia，Africa and Europe，the legal drinking age ranges 16-18．
In plenty of places though，the official drinking age is ignored，and even young children can buy alcohol if they have the money to pay for it．
No matter how old you are，you should always be responsible with alcohol．Teenagers in Milan are now learning that their reckless （不顾后果的） drinking behavior may come at a high price．
 53．The new law by the city of MilanC．
     A．is welcomed by Italian young people
     B．aims to keep Italy's sipping culture alive
     C．forbids selling alcohol to people under 16
     D．has reduced the number of underage youths getting drunk

    A．they've received complaints from many young Americans about the unfairness of the laws
    B．hey agree that people old enough to vole and join the army should be allowed to drink．
    C．they don't want to see US teenagers going to neighboring countries for a drink
    D．they believe the law is pushing underage youths toward alcohol instead of stopping them
56．What can we infer from the passage？A
    A，In many places the shop owners don't mind selling alcohol to underage customers．
    B．The author thinks that US teenagers should go to Canada or Mexico to drink．
    C．Restaurants in the US don't sell alcohol to people under 21 for fear of a    700 fine．
    D．Teens in Milan have to pay a lot of money for their reckless drinking behavior．
9．While taking pictures of a curious five-month-old fox，photographer Simbn Czapp soon realized his subject had quite an interest in photography herself．The clever fox was so curious about the camera equipment that she climbed it on top of it．And while she was supposed to be the subject of the shoot，the fox stood on the shutter release button （快门按钮）and took her own frames．
Mr Czapp visited the New Forest Wildlife Park to capture images of new arrival Jessie．She has been at the animal park in Ashjurst，Hampshire-home to wolves，deer and other animals in 25 acres of ancient woodland-after being abandoned by her mother．
Mr Czapp said，"Jessie was very playful and curious and not at all camera shy．Soon after I arrived she was chewing my shoes and everything seemed to be a game to her．Then she started exploring the camera I had set up on a tripod （三脚架）．She stood on her back legs to look at the back of the camera．She balanced her front paws on it and at one point knocked it over．"
He put the camera back on the tripod and Jessie soon jumped back up．At one point she had all four paws on the camera and was keeping her balance．Mr Czapp added，"She jumped up there several times and I realized it could make a good picture．As I was leaving with the public's viewing window behind me，I thought I heard the camera go off but didn't think much of it．But when I checked the memory card afterwards，I was amazed to see Jessie had actually taken two pictures of me photographing her．I couldn't believe a fox had gained an advantage over me!Jessie is a lovely little fox．There were some lovely photos of her but she obviously thought the photographer was worthy of a picture too!，
44．The underlined word"frames"in Paragraph 1 probably means"B"．

8．A woman named Emily was asked by the woman recorder to state her oocupation at the County Clerk's office．She hesitated，not knowing how to answer．
"Do you have a job，（21）Dare  you just a…．"explained the recorder．
"Of course I have a job，"answered Emily．"I'm a （22）C．"
"We don't list'mother'as an occupation…'housewife'（23）Ait，"said the recorder．
However，I disagree with the recorder．

7．When I was eight，I wrote my first poem．My mother read and cried．"Buddy，you didn't really write this beautiful poem!"
Shyly，but （36）A，I said yes．She poured out her （37）A．"It was nothing short of talent!"
"What time will Father be home？"I asked．I could hardly wait to （38）B my work to him．
I spent quite some time （39）D for his arrival．I wrote the poem out in my finest flourish （花体字），drew a fancy border around it，and （40）B I placed it right on my father's plate on the dining table．My father had begun his motion-picture career as a writer．I was sure he would be able（41）C my poem．
At almost 7o'clock my father burst in．He seemed （42）A．He circled the dining-room table，complaining about his employees．

"If you don't mind，I'd like to decide for myself．"Father said．
I （43）C my head as he read that poem．It was only ten lines．But it seemed to take hours．Then I heard him dropping the poem back on the table．Now came the moment of （44）C．
"I think it's terrible，"he said．
I couldn't look up．My eyes were getting （45）A．

6．It was already dark when an old man came to a small town．He found an inn and wanted to stay there for the night．After he had gone to his room，the owner said to his wife，"Look at his bag，dear．I'm sure there are lots of valuable things in it．I want to steal it when he is asleep．"
